How Set Model Item Hidden Property Programmatically?

Jun 1, 2006

I have a requirement to create a Report Builder Model programmatically and include only a subset of the Entities (Tables) in the Database referenced by the Data Source. What I have to do is create pre-filtered 'datasets' with application security (Role, User) already applied.

When I build a Model via GenerateModel() I get every table. This is because, unlike using Model Designer, I do not get to pick and choose which tables are to be included in the Data Source View.

Note: I cannot apply any security to the Model itself. This is as painful as applying security (table, column, row) directly to the database.

The answer is to set the Hidden 'property' at the Entity Level. I was hoping to use GetProperties() and SetProperties() but this is limited to Catalog Items? I know I can do this by 'editing' the SMDL(XML) and inserting

<Hidden>true</Hidden>

for the Entities I don't want to see but there *has* to be a better way.

Referencing One Item's Hidden Property In Order To Set Another's Hidden Property

Feb 15, 2007

Hello,

I have a group I'll call G4.

The header table row for G4 contains 3 textboxes containing the sums of the contents within G4. The header table row for G4 is visible while it's contents, including the G4 footer table row, is kept invisible until the report user drills down into the group.

When the report user drills down into G4 the footer table row becomes visible and the sums of the contents of the group are displayed for a second time.

At this point I want the sums in the header to be set to invisible when the sums in the footer are made visible by the drilldown.

When I try to reference the hidden property of textbox66 in the G4 footer in order to set the hidden property of header textbox57 in the G4 header I get to this point...

=IIF(reportitems!textbox66.

When it fails to give me an option of choosing the .Hidden property and instead only gives me a .Value.

If I complete the IIF statement manually so that it spells out .....

=IIF(ReportItems!Textbox66.Hidden = False, True, False)

...the report chokes on it.

So my question is, how do I reference the hidden property of one or more textboxes in a group to use as condition checks to set the hidden property of another textbox in that same group?

Thank you for any help you can provide. We are only now beginning to implement reporting services and I have not yet had the chance to research this in greater detail for lack of time.

Export To Excel, CSV, XML With Expression In Hidden Property Omits Data

Jun 7, 2007

I have a matrix table with a rectangle in the data cell. The rectangle has an image and textbox. The textbox has an expression in it's Hidden property based on the column name. The report renders fine on screen. When the report is exported to Excel, CSV, XML the textbox contents are not output (the images display as expected). I've tried setting the DataElementOutput to Output/Yes with no success. Exporting to TIFF, PDF, Web Archive/MTHML is fine.

Programmatically Change Property

Apr 24, 2006

In the old DTS, we can use the ActiveX Script to change any task's property programmatically.

Can we still do it in SSIS? Using the Script task? It seems changing the value of variables then use a expression can do some of the work, but what if a task has no expression defined?

Say, I want to change the Fuzzy look up reference table name.

Can we do it?

Model Item Security Setting

Jan 4, 2008

Hi
I just deploy a report model and want use report builder to create ad-hoc using this report model.
I want some entitis and attributes are not visiable for some user, so I config the model item security for this model.
But no matter which user I use to login the report server, I always can access all the entities.
Even I delete all the groups and users in "Permissions" property of the model, I still can access this model through report builder.
All the user I used to test are local user of server with report service, my server is SQL Server 2005+SP2.

How can I fix it?

Report Model Item Security Has No Effect

Apr 25, 2007

Hi,



I am trying to use a very easy and simple feature of a reportmodel, model item security.

In my example i have two users; HGHJohn and HGHJKooi



I want to test if I am able to restrict access in the model to a whole entity. HGHJKooi shouldn't be able to see the entity 'Customers'.



These are the steps I executed:

1. In Sqlserver management studio I opened the properties of my model and navigated to the tabpage 'model item security'.

2. I activated the option 'secure individual model items...'

3. In the root of the model I declared two users(groups) as specified above

4. Automatically all nodes inherit these settings from the root.

5. For the entity 'Relations' I change the default, by selecting 'use these roles for each group or user account'

6. I removed HGHJKooi from this list, leaving only 'HGHJohn as model item browser



What I expected at this moment is that when I login the system as HGHJKooi, then I won't see this entity, but I still can! Does anybody know a solution to this problem?

Programmatically Create A Report Model

Jul 14, 2007

Hello,

What we'd like to do is programmatically generate and maintain a report model based on how the individual install is configured. I've found some documentation that makes me believe this is possible, but I'm hoping someone can nudge me in the right direction. The ReportingServices2005 class has several model related methods (CreateModel) and I found the .xsd for the semantic model XML file
(http://schemas.microsoft.com/sqlserver/2004/10/semanticmodeling/SemanticModeling.xsd),
but no real documentation on how to put together a Report Model document from scratch. Looking at the files generated from BIDS is somewhat overwhelming and I have no idea where I'd pull most of the information.


Finally, I want to create Report Model(.smdl) file without Report Model Designer.

I want to Implement CreateModel Method to create new model, any source code sample..??


Any help that can be provided would be greatly appreciated. Thanks!

Process A Mining Model Programmatically

Mar 28, 2007

I have tried to process a data mining model that I have produce programmatically. I use the following code for processing



Private Sub BtProcess_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtProcess.Click

' Now some different styles of processing

'Process mining structure first - don't process the models though

' ms.Process(ProcessType.ProcessStructure)

ms.Process(ProcessType.ProcessStructure)

DeclareBox.Text = "Process Data Mining Structure"

' Process the mining model only (because the structure has been processed above

' We could have said ProcessDefault without processing the structure first, though

mm.Process(ProcessType.ProcessDefault)

DeclareBox.Text = "Process Data Mining Model"

End Sub



I use the following code for data mining model and is correctly designed



Private Sub CreateMiningModel()

Dim mc As MiningModelColumn

mm = ms.MiningModels.Add(CbDatabase.Text & " miningmodelName") ', Utils.GetSyntacticallyValidID(miningmodelName, Type.GetType(MiningModel)))

mm.Algorithm = "Microsoft_Decision_Trees"

mm.AlgorithmParameters.Add("COMPLEXITY_PENALTY", 0.3)

mc = New MiningModelColumn("SUMCODE", "SUMCODE")

mc.SourceColumnID = ms.Columns("SUMCODE").ID

mc.Usage = "Key"

mm.Columns.Add(mc)

mc = New MiningModelColumn("STAFF_YES", "STAFF_YES")

mc.SourceColumnID = ms.Columns("STAFF_YES").ID

mc.Usage = "Input"

mm.Columns.Add(mc)

mc = New MiningModelColumn("D_G_OZODIS_IPER", "D_G_OZODIS_IPER")

mc.SourceColumnID = ms.Columns("D_G_OZODIS_IPER").ID

mc.Usage = "PredictOnly"

mm.Columns.Add(mc)



and I received the following error message. Any Ideas? What is wrong with this? Thank you in advance

Analysis :: Hidden Power Pivot KPIs - Not Hidden In SSAS

Aug 20, 2015

Given a model in Power Pivot with a number of KPIs that are hidden with the 'hide from client tools' option. After restoring the model in SSAS and connecting to the model from Excel, the KPIs are visible under a separate category/table "KPIs".

Other hidden items in the model like columns and measures remain invisible.

Is this normal behavior and what can I do about this?

SSRS -- Security Filter And Model Item Security Setting

Jul 31, 2007



Hi,


I have posted this issue for a week, haven't got any reply yet, I posted it again and desperately need your help.


The article http://msdn2.microsoft.com/en-us/library/ms365343.aspx says:
Model Item Security can be set for differnt security filters, but when I use SQL Server Management Studio to set Model Item Security, it seems "Permissions" property surpass "Model Item Security" property. -- My report server is using Custom Authentication.



For example, in "Permissions" property of the model, if I checked "Use these roles for each group or user account" without setting any user or group, no matter what users I added to "Model Item Security" with "Secure individual model items independently for this model" checked, NO one user can see the model on report manager and report builder;

in above situation, if I added "user1" and gave role such as "Browser" role to "user1" in "Permissions" property, if I checked "Secure individual model items independently for this model" in "Model Item Security" property, even I did NOT grant "user1" to root model and any entities under the model, the "user1" is able to access the model and all entities in report builder.



My question is on the same report model, how to set "AdminFilter" (empty security filter) for administrator permissions and set "GeneralFilter" (filtered on UserID) for general user based on their UserID?


The article also says:

"Security filters are always applied, even for users who have Content Manager or Administrator permissions to the model. To allow administrators or other users to see all rows of an entity on which row-level security is defined, you can create an empty security filter (which always returns True) and then use the filter to grant those users access to all the rows."



So I defined 2 filters "GeneralFilter" and "AdminFilter" for "Staff" entity for my report model "SSRSModel", I expect after I deployed the report model, the administrator users use report builder to build reports with all rows available, and the non-admin users can only see rows based on their UserID.



I can only get one result at a time but not both:

either the rows are filtered or not filtered at all, no matter how I set the "SecurityFilter" for the entity: I tried setting both "AdminFilter" and "GeneralFilter" for SecurityFilter at the same time, combination of "DefaultSecurityFilter" and "SecurityFilter", or one at a time.



Your help is highly appreciated!

Help, Running A Control Flow Item Does Not Kick Off The Next Item

Mar 6, 2007

Hi,

Here's my problem. I have 2 tasks defined in my Control Flow tab:

EXECUTE SQL--------->EXECUTE DTS 2000 PACKAGE

When I attempt to run it, by right-clicking the EXECUTE SQL task, and selecting "Execute Task", it only runs the EXECUTE SQL part (successfully), and does not "kick off" the EXECUTE DTS 2000 PACKAGE, after it is done running (even though it completes successfully, as shown by the green box).

Yes, they are connected by a dark green arrow, as indicated in my diagram above.

Why is this?? Am I missing something here? Need help.

Changing Code Page Property Using Property Expression Doesn't Work

Jun 16, 2006

I am having problems exporting data into a flat file using specific code page. My application has a variable "User::CodePage" that stores code page value (936, 950, 1252, etc) based on the data source. This variable is assigned to the CodePage property of desitnation file connection using Property expression.

But, when I execute the package, the CodePage property of the Destination file connection defaults to the initial value that was set for "User:CodePage" variable in design mode. I checked the value within the variable during runtime and it changes correctly for each data source. But, the property of the destinatin file connection doesn't change and results in an error.

[Flat File Destination [473]] Error: Data conversion failed. The data conversion for column "Column01" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.".

[DTS.Pipeline] Error: The ProcessInput method on component "Flat File Destination" (473) failed with error code 0xC02020A0. The identified component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running.

If I manually update the variable with correct code page and re-run the ETL, everything works fine. Just that it doesn't work during run-time mode.

Can someone please help me resolve this.

Thanks much.

Value Of A Readonly Property Of Custom Task Is Not Updated In Property Window

Apr 17, 2008

Hi,

I developed a simple custom control flow component which has several read/write properties and one readonly property (lets call it ROP) whichs Get method simple returns the value of a private variable (VAR as string). In the Execute method the VAR has a value assigened. When I put the value of ROP or VAR into MsgBox I can see the correct value. However when I execute the component I can not see the value of the ROP in the property window. I see the property but its value is empty string. For example when I put a breakpoint to postexecute or check the property before click OK in a MsgBox I would expect that the property value would be updated in SSIS as well. Is there a way how to display correct values of custom tasks properties in property window?

Thanks for any hints.

(URGENT) Cannot Be Written To The Property. The Expression Was Evaluated, But Cannot Be Set On The Property

May 7, 2008

Untill recently I had a smooth running SSIS package,but suddenly it throws error syaing
"OnError,,,,,,,The result of the expression

"@[User:trTextFileImpDirectory] +"SomeTextStringHere"+ @[User:trANTTextFileName] +(DT_STR,30,1252) @[User:taging_Date_Key]+ "SomeTextStringHere"
" on property "ConnectionString" cannot be written to the property. The expression was evaluated, but cannot be set on the property."

I have child SSIS package running under a parent package (through execute package task)

I have few flat file connection managers in child package for text file import , in which I am building text file path dynamically at run time by assigning an expression in connection string property of connection manager.
The Expression is as follows



"@[User:trTextFileImpDirectory] +"SomeTextStringHere."+ @[User:trANTTextFileName] +(DT_STR,30,1252) @[User:taging_Date_Key]+ +"SomeTextStringHere"

Where @[User:trTextFileImpDirectory] is a variable which contains path of directory containg text
files.Value in this variable is assigned at runtime from parent package's variable,which in turns fetch
value from a configuration file on local server.

With my current configuration this path has been configured to some other server's directory over network ( I.e my package picks text files from some other servers folder over network)

While
"Some string here"+ @[User:trANTTextFileName]" part of file name string.

(DT_STR,30,1252) @[User:taging_Date_Key] Contain the date of processing ,value in this variable is also picked up at run time from parent package variable.

1) So can someone give me some insight into possible reason of failures.
2) Is it possible that problem arises if directory (from which I m picking text files) is assigned password or is there exist some problem in accessing forlders over network ?
3) Or there can be some problem in package configuration at design time( I.e where I m assigning value in variable from parent package vriables)?

The report shows orders that customers have placed that contain 0 promo items, All promo items (all items in order are promo items), and a mix of promo and non promo (at least 1 promo item and 1 non-promo item). Ive simplified this a bit for ease of understanding but lets assume we have 2 tables: A Promo table that contains the items on promotion and the dates that promotion is valid, and a Sales table, that contains the order number, order date, and sku ordered.

I've already written code that finds orders that have at least 1 promo item in them, and using that, I can determine what orders have 0 promo items in them. Where I am stuck is taking the orders that have at least 1 promo item in them, and separating them into orders that have only promo items, and those that have both promo and not promo items in them. Also, there are several promos throughout the year (called "Offers") so in my code below, you can see 2 different Offers ("JF" and "MA") with their corresponding dates they are valid. They will never overlap. My results also have to be split out by Offer so management can look at the results of each offer separately. Here is some code:

Code:
create table #Promos (
Offer varchar(2) null,
SKU int null,
StartDt date null,
EndDt date null

[Code] ....

So my results should show OrderNo A1111 in the Promo and No Promo group because of SKU 5 not being promotional during the time that order was placed. OrderNo A2222 should be in the Promo Only group because both SKUs on the order were promotional at the time the order was placed.

Power Pivot :: Building A Model Based On Multinational Model With Different Languages?

Oct 19, 2015

I need to develop a language specific dwh, meaning that descriptions of products are available from a SAP system in multiple languages. English is the most important language and that is the standard. But, there are also requirements of countries that wants productdescriptions in their language. 

Productnr Productdesc Language
1            product       EN
1            produkt       DE

One option is to column the descriptions, but that is not very elegantly. I was thinking of using bridge tables to model this but you have to always select a language in a filter (I think)..

I'm thinking of a technical solution, such that when a user logs on, the language is determined and a view determines whether to pick a certain product table specific for a certain language. But then I don't have the opportunity to interchange the different language specific fields in a report (or in my case PowerPivot).

Can We Pause Log Shipping, Bring Primary Db To Simple Recovery Model And Then Back To Full R Model?

Apr 25, 2008



We have the following scenario,

We have our Production server having database on which Few DTS packages execute every night. Most of them have Bulk Insert stored procedures running.

SO we have to set Recovery Model of the database to simple for that period of time, otherwise it will blow up our logs.

Is there any way we can set up log shipping between our production and standby server, but pause it for some time, set recovery model of primary db to simple, execute DTS Bulk Insert Jobs, Bring it Back to Full recovery Model AND finally bring back Log SHipping.

It it possible, if yes how can we achieve this.

If not what could be another DR solution in this scenario.

Thanks Much

MS Time Series - Quick To Process The Model But Takes Very Long Time To Open Mining Model Viewer

Oct 27, 2007

Hi all,

I have MS Time Seeries model using a database of over a thousand products each of which has hundreds of cases. It amazingly takes only a few minutes to finish processing the model, but when I click Mining Model Viewer to view the models, it takes many hours to show up. Once the window is open, I can choose model for different products almost instantly. Is this normal?

Can someone please give a query for getting the list of all hidden reports from "Report Server Database" tables?

Hidden Parameters

Dec 14, 2005

Is there any way to have a parameter hidden for a report without it being Read-Only? I want the user to be able to select a specific parameter within a report and have another parameter passed via URL.

Should Hidden Stored Procedures Be Used?

Mar 16, 2004

Should stored produres that are "hidden" from us users be used?
I'm thinking in particular of using sp_MSgetversion to get the SQL Server version number and to be able to run different script if i'm on SQL Server 7.

Why are they not documented in the first place? Is it because they might change and they don't want us to use them?

Hidden Expression For Table

May 23, 2008

Hi all,

My report has a number of tables.
These table design is as [Total(numeric),Year(numeric),Month(varchar(15)].
Each table on report is populated based on individual tables in Mngt Studio.

My problem is.If table is empty,the table on report does not get populated/displayed.It is hidden.How do I return a message,Example {"No Value for table A"} instead and show the table in report only when the table has some value.

I have written an expression like this.But it just hides the table if its empty,and im not able to return a value "No Value"instead.

=IIF(Fields!Month.Value IS Nothing,"No Value for table A",False)

I have a package with an Execute Process task that is running csvde. I need the window style to be "hidden" in order to be able to run the package as a job. However, selecting the "hidden" option is not causing the window to not be displayed. Am I missing something?



Thanks,

Null Hidden Parameter

Aug 1, 2007

In my report I have a dataset that is returning an ID field among other things. I am setting a hidden parameter = to that ID field. That parameter is then used to return another dataset.

My problem is that the original dataset with the ID field does not always bring back data (this is expected). If data is not brought back, I get an error when I try to execute the report ("The 'X' parameter is missing a value").

I have the parameter set to "Allow Null Values".

This value is not required in the SQL Server stored procedure that returns values for the new dataset.
The parameter is of type Integer. (So I am not able to set the "Allow Blank Value" property)
This is NOT a multi-value parameter.


Does anyone have any suggestions/ideas/workarounds to solve my problem?
