Power Pivot :: Structural Data Model Changes In Data Source Leads To Errors
Oct 12, 2015
I've question about how to handle structural datamodel changes in a datasource of PowerPivot. Suppose I'm developing a starmodel in SQL Server and sometimes a datatype changes or a name of a field changes in a table. It seems to me that PowerPivot handle this not gracefully as Analysis MD does (mostly). I received an error because of a wrong fieldname or even no error when a dattype changes in PowerPivot. Is this common or do I something wrong here. Does this mean that every time the datamodel changes the PowerPivot should be recreated? Or am I missing the clue here?
I have an Excel 2013 file with lots of DAX connected to an Azure database. I'd like to reuse all that work by changing the data source for the PowerPivot model to a different database which is an exact copy (just empty) on the same server, but Excel won't let me. In PowerPivot I can change the database connection, the user ID and password as well as the connections name. When opening each table properties (inside PowerPivot model) the new connection is used and all old data is removed, but as soon as I refresh using Existing connections, both from PowerPivot or from the Excel Data tab, the old connection is used and old data is reloaded.
If I use Existing connections from inside PowerPivot, I can se that the new connection is highlighted and has the correct variable, but I think maybe that one is run first, then the old one is run afterwards (or something like that).
On the Excel Data tab, I can see that the old connection is the only one Excel itself seems to know about, but I cannot change anything there as it's read-only.
There must be a way to change this. Even with copy and paste it would take me days to recreate this Excel file from scratch and it would be a serious flaw and reduction of usability for PowerPivot.
I don't know if the question has been nailed down. Aside from deleting tables, can we delete the *content* of data within the tables. It doesn't seem crazy that, if you can pull in data from a feed then you should be able to remove the content out again (without also destroying the user's meta-data work ). Reasons for this include:
- Security (a user may not have rights to see *my* data and should go refresh their own) - Size (workbook doesn't need to have GB's of irrelevant data saved to disk in a workbook if it was just useful during development phase to a pre-production data feed) - Bad data (pre-production data feed is not good data) - User-friendliness (data feed was refreshed 2 years ago and workbook was saved to file server. Users shouldn't be presented with irrelevant data, but should get empty pivot tables until they go do their refresh)
Obviously Excel internally knows how to clear out PowerPivot data, given the prompt shown here: [URL] ....
But how does a user initiate this on their own (corruption aside)?
Previous time this question was asked, without a real resolution: [URL] ....
1) Production data with column headers: Key, Facility, Line, Time, Output 2) Costs data with column headers: Key, Site, Cost Center, Time, Cost
The tables have a common key named obviously as Key. The data looks like this:
Key Facility Line Time Output Alpha
I would like to have two pivot tables which I can filter with ONE slicer based on the column Key. The first pivot table shows row labels Facility, Line and column labels Time. Value field is Output. The second pivot table shows row labels Site, Cost Center, and column lables Time. Value field is Cost.How can I do this with Power Pivot? I tried by linking both tables above to a table with unique Keys in PowerPivot and then creating a PivotTable where I would have used the Key from the Keys table.
I need to create a data model for powerview report but I don't have data right now. The data will be loaded later after I create the report. What technique should I use??
I have created 60 queries and added them to my data model in Power Pivot/Excel 2016. I created some calculated fields for one of my queries but I would LOVE to know how to just copy these across all queries in the data model instead of having to create them in the data model for one query at a time. That will take forever.
Is it possible to generate automatic refresh of excel 2013 table which displays some table of a power pivot model on file open?? I dont want to use pivottable (which supports this ...)
Is it possible to include a currency symbol in an amount-field in PowerPivot/Pivottable based on a Currency column in a table? Something as the same as with SSAS MD. And I don't want fixed values in my code.
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).
I'm currently working on a BI architecture for a customer, and consider to propose the Power BI data catalog as a data distribution layer. The customer will use Power BI, but also has other BI tools.
Are data sets in the data catalog available to other clients than Power Query alone? E.g. are there OData feed endpoints available? If not, what would be the best way to give other tools access to the data?
I have some data in Excel - sheet1 which would be static.
Now I need to import data from SQL Server (using a query) and Union above static data with this SQL data and later I will have to create PowerPivot table in Sheet2.
Which is suitable option for me to import data from SQL to excel as I see "From SQL Server" option under "Data" and "Power Query" tab as well.
How to merge above SQL data with existing static data?
I am trying to build various reports that compares data over time. I have one that measures Year Over Year % difference for number of incoming projects. I managed to do that easily by calculating the following
Where Projects is the metric in question, TrendData is the table that contains project data and CalendateDate is the Date Table. But now I am trying to compare the same YTD projects data to number of projects that came in the last 6 months. How do our projects compare to average number of projects that came in last 6 month period.
I tried the the DATEADD function instead but got no luck and data came out wrong!
Is there an open APISDK for sharepoint's power pivot galleries allowing on demand processing of a power pivot model over there? Ideally from a SSIS package?
I have a pivot table that connects to our data warehouse via a PowerPivot connection. The data contains a bunch of comment fields that are each between 250 and 500 characters. I've set the columns in this pivot table to have the 'Wrap Text' set to true so that the user experience is better, and they can view these comment fields more clearly.
However, whenever I refresh the data, the text wrapping un-sets itself. Interestingly, the 'Wrap Text' setting is still enabled, but I have to go and click it, then click it again to actually wrap the text. This is very burdensome on the user, and degrading the experience.
Any way to make this text wrapping stick so that I don't have to re-set it every time I refresh the data?
i have a model contains fact of account revenue , a time dimension and scd of account.
the scd (type 2) is changing when an account get a new color.
when i queries the model by PowerPivot i sometimes get wrong color for an account in a date priod , for example , I would expect to see color 3 for account 1 at 04-06-2010 , But instead I see color 1 - as you can see in the picture bellow.
FACT , SCD :
Result
i process all , deploy , mark dim_time as date dim , and i still cant find the error.
I am getting this exception "An error occurred while loading the model for the item or data source '<filename.extension'>. Verify that the connection information is correct and that you have permissions to access the data source."" when I click in Power View icon in Power Pivot Gallery SharePoint.I tried steps mention this TechNet article but the issue is still not resolved.URL...
Is it possible to rename a field-name from ( tabular powerpivot ) model to a different Presented-name for the end user ?
usualy the names in the source model are Understandable to the developer , and its Custom to his understanding and nees , but for the end user its not - its not understandable , to long and so far form the regular terms in his Business , and also the language Might be non-English..
I am connecting to an Access data source which is password protected. But when I set up the connection in PowerPivot what User name do I need to use for the connection. I have tried various log on user names but non have worked.
I have a formula that should use data from 2 slicers:
Spend per period (changing currencies & dates):=[Spend per period]*CALCULATE([Sum of Value],FILTER(Currency,Currency[Date]=[End Date]),FILTER(Currency,Currency[Attribute]=CurrencySlicer[Attribute]))
I managed to link the [End Date] from the slicer to the formula, however the [Attribute] field is not numeric so I can't duplicate the same methodology.
{FYI: End Date:=LASTDATE('Finish Date Slicer'[Column1]) }
I assume that I need to build a formula to extract the data chosen in the slicer, and can't connect it directly to the slicer.
I have a powerpivot table which groups customers into ranges of sales figures. When I use a slicer to slice by region, I lose some of the ranges because they contain no data. I need them to show up even if there is no data. I've checked all of the boxes to "Show items with no data on columns (and Rows). But this has no effect. I created a measure using the following formula which also has no effect.
My PowerPivot report is using quite large data that can be split by subsidiary. I’d like to let user select subsidiary. The selection would trigger change of the PowerPivot’s data connection so that the SQL would change into “SELECT
* FROM dbo.ECSPURSL00 WHERE Subsdiary = 'selected subsidiary'”.
The Excel 2013 has Model class that should manage the PowerPivot data sources. The object explorer shows CreateModelWorkbookConnection method, but I can't figure out the VBA syntax.
I have a DATESMTD function which is not working. This is what is happening, if there is no row data for the month it creates a month to date total similar to the year to date total instead of zero. See below my formula:
MTDSUM:=CALCULATE(SUM('Combined Years Dataset'[Net]),DATESMTD('Combined Years Dataset'[Period2]),'Date'[date])
Period 2 is a column with dates (end of monthdates) in a table called Combined Years Dataset.
So, if I have $200.00 data for Aug and no data for Sept, the system puts in 200.00 as the month to date for Sept instead of zero. What can I do to make the system insert zero in the month to date column instead of the $200.00. What am I doing wrong in the formula.
how to combine measures and fields coming from an analytical model (tabular) along with some Excel calculations. Basically I want to provide users with a simple report (to be displayed in SharePoint Excel services) containing charts and slicers. The data comes from a tabular model, and most of the calculations are in the model as well.However there is some little tweaking that must be done. For example I might need additional calculated columns, but I don't feel the need to modify the tabular model for that. I was wondering if I could do this within Excel as well -- but without having to bring all the data through a pivot table, then manipulate it and then show it on the report. So to be clear I do not want any pivot tables lying around, even if on a hidden sheet.
I noticed that when selecting a pivot chart in Excel, at the ribbon menu under "PIVOTCHART TOOLS"/"ANALYSE" there is a group of buttons named "Calculations". One of them is named OLAP Tools.Is it fair to assume that these options will allow me to create new measures at the Excel side, without affecting my tabular model?
I have been given a request by a business analyst to update the text 'old' to 'new' within the column names / measure names and associated calculations within a PowerPivot model. There are hundred of columns / measures / calculations, etc. which need to be renamed.
Is there any way of updating these changes to the model other than making these changes manually or is there some way of doing the following type of operation in PowerPivot; -
UPDATE tblColumnNames SET Column_name, etc REPLACE ('old','new', all columns),('old','new', all measures),('old','new', all calculations) FROM tblColumnNames
I am trying to import the data from SharePoint into my PowerPivot window as a Datafeed. I am able to successfully import the whole data from SharePoint list. But, now i would like to apply a filter (Where Clause) before importing the data.
When we deploy any PowerPivot Data Model to SharePoint 2013, we get the following options-
1. Create New PowerPivot Report 2. Create New PowerView Report 3. Schedule Data Refresh
These options work fine as long as we deploy a normal Excel Data Model file like .xlsx . However, When I deploy Data Model with some VBA code (Macros, VB functions) contained within it i.e. Macro Enabled file - .xlsm,the above options didn't work. I got following error while creating a New PowerView report as It says that your Excel has unsupported features like Macro function.Can't we create a new PowerPivot/PowerView report with Macro Enabled Data Model? Is this not supported in SharePoint 2013?
Purpose - relate Server to Software, and Server to App and display it in power view.Current State - I am able to display that Server/Software and Server/App combos separately in power view. However when I add Server/Software/App it throws the warning as seen below. This leads me to believe the relationships aren't transitive so to speak.
Supporting Info - v_gs_installedsoftware is the software table. It relates to v_r_system which is the server table through resource id. The software table can have many rows with the same resource id, however the server table only has unique resourceids (think of it as a server can have many software products installed). Table1 is the application table, it relates to the v_r_system table through the resourceid. Each server from the server table can have many applications that it actually plays a role in (think of a web server that hosts multiple websites for different business units).
I have an Excel database file that contains the total passenger passes from a specific location. The total number of passenger passes is counted in a period of 2 minutes(e.g. 14:45:00 to 14:46:59). I have imported my database into PowerPivot and have also created relevant PivotTables and PivotCharts with some slicers to analyze them. How can I create a slicer which filters data in greater periods of time like hour, day or month?
Trying to modify the workbook connection string but it is greyed out and unable to change the Provider= from SQLNCL10 to SQLOLEDB. I am able to change the PowerPivot Data Connections connection string but not the workbook connection string. On the forum only see where people have asked the question but it seems like the people who've asked ended up recreating the data models.
I have uploaded excel report with data model , but when i click on ,anage data refresh link it is showing shedular disable. I have check logs then I am getting analytics server connection time out error.
Right now architecture of system having different analytics server and sharepoint server is also different. Any better solution due to which i can able to schedule my reports.
