Forecasting TimeSeries From Cube

Mar 30, 2007

I've saw many tutorials about using TimeSeries. But all of them using a table. But I'm using a cube to represent data. So I'm trying to build forecast from cube, but it doesn't so good as in could be.
I've got the same problem as desribed in Microsoft's tutoral Adventure work. So I need to forecast a series of sales.
The problem is that I can't create second key value, as it shown in tutorial. So I can't split good's sales. I have created dimentions for goods and for time. So cube's browser shows me very handsome view, but the problem with mining model still remains...
Please, help me! How can I solve this problem?
Can I create a separate table from cube to build forecast by this table?
Or I can solve this problem not using tables?

Product Sales Forecasting.

Jul 13, 2006

Hi,

We are trying to forcast product sales for next three months based on their sales for previous 12 months. In this case, Microsoft Time Series algorithm requires the sales data to be present  for each product for past 12 months (???). However, our products have typical life span of 6 months and obviously the new products will not have sales before they were added. Any help will be very much appreciated.

Thanks

Riju

Forecasting Mining Model, Performance And Viewer

Jan 31, 2008



In order to setup my forecasting mining model I have created a special view that runs against my fact table and creates time series on the level I need.




Code Snippet
Select DFUKEY, DATE, QTY from Dim_FACT where DFKEY like '020%'

So I get the following input fr my model:


time series key (e.g. DFUKEY)

date (time key)

QTY (to be predicted)

For testing purposes I created a small view (similar to AdventureWorks) that only contained a few time series. The model was created and processed in ~2 minutes or less. The viewer came up almost immediately and I was able to see results.

Now my real view has about 25000 time series I need a forecast for and that I also like to review in the viewer. If I create a mining model against that bigger view the processing takes ~15m or so and the viewer is likely to time out.

The worst part thought is when I try to get the forecast for a time series (see query below) it takes minutes before the answers come back.




Code Snippet
SELECT FLATTENED [DFUKEY], PredictTimeSeries([QTY], 12)

FROM [TimeSeries]
WHERE [DFUKEY] = '02078147AG'




I would understand if without the WHERE clause it would take long but as is?

I am pretty sure I created the model the right way so I wonder if somebody can give me recommendations as to how forecast larger numbers.

Finally I intend to call the foarcast for a particular series using an Action from within a cube.

Thanks in advance.
Dirk

Analysis :: Possible To Create Multiple Data Source View Having Same Datasource?

Jul 27, 2015

1. As per my current development SQL Sever Analysis Database consists of two Cube (Cube A and Cube B).  Cube A and Cube B share the same data source view (DSV1). The source for both these cubes has the same data source (DS1).

2. As per the requirement I need to create third Cube i.e. Cube C. Is it possible to create a second Data Source View (DSV2). The Source of second Data Source View (DSV2) will be the same data source(DS1).

I am thinking to create second Data Source View (DSV2) for Cube C because existing layout of the DSV1 has become complex. I wanted to know the pros and cons of creating a multiple data source view with same data source

Analysis :: Grand Totals Not Adding Up In Power View On Molap Cubes?

Nov 12, 2015

My Power view reports do not show the grand totals correctly.  I think my issue relates perfectly to [URL]. However we have updated service pack 2 on both the sql data warehouse and the ssas box.  They are 2012.  However the power view is still incorrect.  Pivot tables seem to work just fine.  In AS I have a 2 separate measure groups that has a total count.  I then use mdx to bring those two together.  Something I have done many times in past with as 2008.  My mdx looks like this below.  I then hide Total Count EC (from measure group 1) and Total Count SF (from measure group 2). This way I have 1 total count value and they can use another dimension to see the two separate if needed. 

CREATE
MEMBERCURRENTCUBE.MEASURES.[Total
Count New] AS
//
([Measures].[Total Count] + [Measures].[Total Count SF]),
DISPLAY_FOLDER
=
'Totals', 
ASSOCIATED_MEASURE_GROUP=
'Report',
FORMAT_STRING
=
"#,#0",
VISIBLE=
1;

The measure Total Count EC works just fine but the Total Count (MDX) does not .  All in Power Pivot works fine but in Power View the grand totals are not correct.

Analysis :: How To Save Parameter From A Report Created In Browse View Under Cube

Nov 10, 2015

After connected to Analysis Services and following the path below:

Analysis Service - Databases - Cubes

I create the parameters for a custom report after right click on a specific Cube and select Browse to arrive at a view where i can define dimensions and parameters as well as drag and drop measure to the report rows and columns. The left top File bottom only give me a Save Selection or Save ALL option. However, i'm not sure where it saves it to or if it saves the settings for this custom report at all.

I pull this report monthly and it's a pain to recreate all the parameters. How to save this template for future pulls or maybe even incorporate the pull into excel for monthly refresh instead?

Problem With Forecasting With Excel 2007 DM Add-in Using Drill-through Data From SSAS 2005!

Sep 18, 2007


Im having a problem with Excel 2007 DM and SQL 2005 and I hope someone out there has a solution.

Consider the following environment:

Windows XP SP2 or Windows Vista, Excel 2007, Data Mining Add-in, SSAS 2005 (with session mining models enabled, an AdventureWorksDW cube deployed and drill-through actions available).

Now take the following steps:

1. In Excel 2007 set up a connection to SSAS

2. Connect to the cube and create a new pivot table report (drag and drop whatever you like)

3. Right-click on one of the cell values in the data region and either select a drill-through action, or, select Show Details in the context menu

4. Ensure that you have at least 10 detailed records that are generated on a new worksheet page; you should have a time-based column in your detailed records

5. Select the table of detailed data, then select the Analyze tab (within the Table Tools grouping) which appears in the topmost menu above the ribbon

6. Click the Forecast button in the ribbon and choose both the field which you want to predict as well as the time-based column (from step 4) as well as the number of time periods to forecast

7. Finally click OK.

1. Having followed these steps on both WinXP SP2 and Vista, I keep coming across the exception: HResult:0x800A03EC. Any ideas as to why this exception pops up? If I was using a normal table of data (which was not generated from a Show Details or drill-through action), then the Forecast button works fine.

I googled it and thought the localization settings for SSAS 2005 and Excel 2007 needed to be the same (initially they werent). Ive tried removing the auto-filters which appear atop each column in the detailed data table prior to clicking the Forecast button, and, Ive also tested for a series of data across a number of time periods with the same result.

Also, a colleague of mine discovered that the column headers that appear by default from a drill-through start with "$[", and, in removing them the Forecast function appears to work.

I would have thought there would be a seamless transition in Excel 2007 between data retrieved from a cube and the DM Add-in featueres (or at the very least, a more meaningful exception message than the one presented).

Is there something Ive missed, or, is there a KB article I havent come across yet? As I know for a fact that the problem is reproducible, is there a fix to this problem on its way to us? Is there a useful workaround that doesn't require manual intervention?

Thanks,
A.

Analysis :: Power BI Analysis Services Connector - Remote Server Returned Error

Mar 5, 2015

I have, a SSAS 2012 tabular instance with SP2, there is a database on the instance with a read role with everyone assigned permissions. When configuring the Power BI analysis services connector, at the point where you enter Friendly Name, Description and Friendly error message, when you click next I receive the error "The remote server returned an error (403)." I've tested connecting to the database from Excel on a desktop and connect fine.I don't use a "onmicrosoft" account so don't have that problem to deal with.

We use Power BI Pro with our Office 365. As far as I can tell that part is working ok as I pass that stage of the configuration with a message saying connected to Power BI.The connector is installed on the same server as tabular services, its a Win2012 Standard server. The tabular instance is running a domain account that is the admin account for the instance (this is a dev environment) that account is what I've used in the connector configuration. It's also a local admin account. There is no gateway installed on the server.

Analysis :: Cube Needs To Be Deployed From VS After SSIS Analysis Services Processing Task Completes?

May 13, 2014

I have a cube that we are processing nightly via an Analysis Service Processing Task in SSIS.  In order to increase the performance of the processing time, we elected to use a lot of rigid dimension attributes, and do a full process of everything in the SSIS task.  The issue that I am having is that after that task completes, I need to go into Visual Studio to deploy the cube becuase we are unable to browse or use the cube.  This issue seemed to start once we changed the SSIS Analysis Service Processing Task to do a full process on the dimensions, rather than an incremental.

I would expect that once development is done, and it is processed and deployed, that is it.  My thinking is that the SSIS task should just update the already deployed cube,

Analysis :: Excel 2013 Pivot-table / Grouping On Date That Comes From Analysis Service 2008?

Nov 24, 2015

I am using

SSAS: version 2008
Excel: version 2013

I am connecting to SSAS cube from Excel and I have date dimension with 4 fields (I have others but I don't use it for this case). I created 4 fields in order to test all possible scenarios that I could think of:

DateKey:
    - Type: System.Integer
    - Value: yyyyMMdd
Date:
    - Type: System.DateTime
DateStr0:
    - Type: System.String
    - Value: dd/MM/yyyy (note: I am not using US culture)
    - Example: 01/11/2015  
DateStr1:
    - Type: System.String
    - Value: %d/%M/yyyy (note: I am not using US culture) 
    - Example: 1/11/2015  

Filtering on date is working fine:

Initially, in excel, filtering on date was not working. But after changing dimensional type to time, and setting  DataType to Date, as mentioned in [URL] filter is working fine as you can see in the picture.Grouping on date is not working:

I have hierarchy in my Date dimension and I can group based on hierarchy, no problem. But user is used to pre-build grouping function of excel, and he wants to use that. Pre-build functions of Excel, Group and ungroup seems to be available as you can see in following picture:

But when user clicks 'Group', excel groups it as if it is a string, and that is the problem. User wants to group using pre-build grouping function available in Pivot table. I also find out that Power Pivot Table does not support this excel grouping functionality. And if I understood well, this pre-build grouping functionality of excel, needs to do calculation at run time, and that is not viable solution if you have millions of rows. So Power pivot table does not support pre-build grouping functionality of excel and hence we need to use dimension hierarchy to do the grouping. But I am not using Power Pivot table, I am using simple Pivot Table. So I expect grouping functionality to be working fine. Then I tried to do simple test. I created a simple data source in excel itself. And use it as source of my Pivot table. Then grouping is working fine. The only difference that I can see is (When double click the Measure value in Excel),For date values of my simple test, excel consider them as 'Date'.

For date values of my data coming from cube, excel consider them as 'General'

    2.1. But value here is same as it was in simple test.

    2.2. 'Date Filter' works just fine.

    2.3. If I just select this cell and unselect it, then excel change type to 'Date' though for that cell. 

    2.4. I have created 4 different types of fields in my date dimension thinking that values of attribute of my dimension might be the problem, but excel consider 'General' for all of them.

    2.5 This value (that can be seen when double clicking on measure) comes from 'Name Column' of the attribute. And the DataType defined is WChar. And I thought that might be the reason of issue. And I changed it to 'Date'. But SSAS does not allow it to change to 'Date' giving error : The 'Date' data type is not allowed for the 'NameColumn' property; 'WChar' should be used.

So, I don't know, what is the puzzle piece that I am missing.

1. Date filter works, group does not work

2. Excel consider it as 'General' string.

3. SSAS does not allow to change 'NameColumn' to Date.

May I transfer from 2005 to 2000 Analysis Services the cubes?

If yes, what is the procedure? The result of migration is the same in the two different versions?


If not, how can I solve this problem?

Alter View / Create View

Aug 14, 2000

I had given one of our developers create view permissions, but he wants to also modify views that are not owned by him, they are owned by dbo.

I ran a profiler trace and determined that when he tries to modify a view using query designer in SQLem or right clicks in SQLem on the view and goes to properties, it is performing a ALTER VIEW. It does the same for dbo in a trace (an ALTER View). He gets a call failed and a permission error that he doesn't have create view permissions, object is owned by dbo, using both methods.

If it is doing an alter view how can I set permissions for that and why does it give a create view error when its really doing an alter view? Very confusing.

View Works, But The Sql From The View Does Not

Selecting A View And Selecting FROM A View Is Wildly Different

Feb 21, 2006

A colleague of mine has a view that returns approx 100000 rows in about 60 seconds.

He wants to use the data returned from that view in an OLE DB Source component.

When he selects the view from the drop-down list of available tables then SSIS seems to hang without any data being returned (he waited for about 15 mins).



He then changed the OLE DB Source component to use a SQL statement and the SQL statement was: SELECT * FROM <viewname>

In this instance all the data was returned in approx 60 seconds (as expected).





This makes no sense. One would think that selecting a view from the drop-down and doing a SELECT *... from that view would be exactly the same. Evidently that isn't the case.

Can anyone explain why?

Thanks

IO Analysis

Mar 13, 2008

I'm looking to see if I have a issue with excessive IO activity caused by less-than-ideal access patterns.

So I've run this query to look at logical and physical reads for logical writes:

selectsql_handle, plan_handle,
total_physical_reads, last_physical_reads,
min_physical_reads, max_physical_reads,
total_logical_writes, last_logical_writes,
min_logical_writes, max_logical_writes,
total_logical_reads, last_logical_reads,
min_logical_reads, max_logical_reads
fromsys.dm_exec_query_stats

The question is, when can it be considered excessive?
Or can you just order the results by descending order and see if you can make improvements on the worst ones?

The same goes for this query for pageiolatch wait counters and times for indexes:
select database_id, object_id, index_id, partition_number, page_io_latch_wait_count, page_io_latch_wait_in_ms
from sys.dm_db_index_operational_stats (null,null,null,null)

Both the domains are trusted . Except that the OS where the Analysis server is running is Windows 2000 . I am trying to connect through SQL 2000 Server with Windows NT 4.0 Server .

We have another Analysis server which is running but on Windows NT 4.0 OS where i can easily register that server .
I tried providing access with all the rights to concerned domains , but in vain .
I am exhausted trying to figure out the problem .

Any assistance in this regard would be of great help to me .
