Analysis :: How To Extract Data From SSAS Cubes Into A Table
Jun 19, 2015
I need to extract data from SSAS' cubes into a SQL Server table.
I already read examples using Linked server (with openquery), SSIS, etc. However, the result always return as many columns per dimension as levels. I need to extract all members of a dimension in a column. E.g., when excecuting the following MDX query in Adventure Works 2014:
select [Measures].[Sales Amount] on columns,
Non Empty [Date].[Calendar].members on rows
from [Adventure Works]
I would like to get this result (MDX query in SSMS), but with keys displayed intead of names:
I'm exploring creating local cube files, .cub from an excel sheet with tables.Would SSAS be able to create one cube from taking data from a 1 way table (A, B, C), a 2 way table (AxB, BxC, AxC) and a 3 way table (AxBxC)?
I have two cube and i would like to get data from both cube and combine the results from both cubes to get final result to display result in SSRS reports like we can do in Stored procedure using temporary tables/Joins.Is there any way in SSAS to combine the data from multiple cubes? Data needs to be retrieved from the cubes based on the user inputs.
Is there any way to track the information about the connections to SSAS cubes through local Excel files (BI usage).
OPreviously, we are tracing the information about the BI usage through the BI SharePoint site. Now we want track the users who are using through local excel files .
Can applications connect to SSAS Tabular mode cubes through ODBC drivers? I have been asked the question specifically regarding SAS, and I can see (for example) SAS Enterprise Guide has the ability to connect to sources via ODBC, so I now need to find out if there are such things as ODBC divers for SSAS (specifically Tabular).
I need to use cubes in VS 2005 web project. I have no clue how to create cubes or use them in my web page. I am familiar with Reporting Services but not cubes. thanks in advance!
I want to implement population data in sales cube.
Fact table has customer code which is foreign key of Customer master dimension which in turn is linked to census data dimension. Census data dimension have city wise population data having foreign keys of zone and state.
I am working with SSAS Tabular. I have a stand alone table with 60 columns and contains 120K records. Table size is 250MB. And trying to build a tabular report out of it and it is taking longer and throwing exception, screenshot attached.
It might be cross-join issues, as workaround created a dummy measure and using in report. But it working for 10-20 k records and beyond throwing same exception. I have 8 GB RAM and 100 GB free disk space.
I have only 1 denormalized table that is being used in a SSAS Tabular model(which is about 3GB). I am doing a POC to convert it into a SSAS Multidimensional and explore it.
1st Question) I am seeing that there is no Primary Key(unique key) in the current denormalized table. (Tabular Model didnt require any primary key). But i think for Multidimensional the key is mandatory? Should i generate a composite key myself in a Named Query based on this table(in the DSV)?
2nd Question) What is the best way to design my Multidimensional Cube/Dimensions based on this single table?
Say if i comeup with a Composite Primary Key called (PK_ID) . Should i be splitting up my facts / dimensions in my DSV using Named Queries similar to below(Using the same PK for my dimension tables also?)
a) FactTable = Select PK_ID, Qty1,Cost1,Price1,Amount1 from Table1 b) StoreDim = Select PK_ID, StoreName,StoreDese from Table1 c) ItemDim = Select PK_ID, ItemName,ItemDesc from Table1
I have 5 cubes, and hierachy defined for all cubes. for example:geography database with 5 continents as cubes and contries as dimensions.Now when i am doing security restrictions on my dimension ex: In USA dimension if i want only to give access to texas region then i should be able to see only texas cities. But i cansee all the states under USA even after selecting only Texas region under Dimension data tab inside ROles section in SSMS.I have tried security at database ,cube level as well as dimension level.But still not working.is that because of some wrong design of cubes or something related to database design.? I am not able to undersand that except roles everything in my cubes or datawarehouse is working fine without and defect in data.
We have created Dimensional Model within SQL 2005 and created SSIS packages to load. We have Pk's on Dimensions and FK's on one Fact table. We are thinking about adding clustered index to Fact that consists of the FK's and order by the Hierarchy within the Fact by Dimension. IS THIS A GOOD IDEA IF WE DRILL DOWN AND DRILL THROUGH = QUESTION #1
We build a CUBE from the dimenionsal model and we do not know how to build indexes on the cube. SO DOES SSAS AUTOMATICALLY BUILD INDEXES IT THINKS IT NEEDS ON THE CUBE AND DO YOU KNOW WHAT THEY ARE?? ALSO IF WE HAVE INDEXES ON DIMENSIONAL MODEL DO THOSE GET USED BY SSAS CUBE THAT WE CREATED WITH AUTO BUILD??? = QUESTION #2..
I have a MDX query , where I have a date Range in where clause.
I want to replace it with Cuurent Date and Last 7 days date.
I tried multiple ways using NOW function , but could not get it correct .
modifying the Query so that I can fetch DATA for last 7 days
SELECT NON EMPTY { [Measures].[X] } ON COLUMNS, NON EMPTY { ([PRODUCT].[PRODUCT].[PRODUCT].ALLMEMBERS ) } DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS FROM ( SELECT ( { [COLOR].[COLORName].&[BLACK], [COLOR].[COLORName].&[BLUE] } ) ON COLUMNS FROM ( SELECT ( [Date].[Calendar].[Calendar Year].&[2015].&[2015]&[3].&[7].&[20150706] : [Date].[Calendar].[Calendar Year].&[2015].&[2015]&[2].&[6].&[20150629] ) ON COLUMNS FROM [MYCUBE]))
I want to replace Date Hard code value , I have used Calendar Hierarchy of date dimension. to find Last 7 days Data.
Is there any way to copy my Data of 2015 to the Planning/Forecasting Value of 2016?
My question is based on that we use INFOR ION BI right now and there we can just add an Button in our reports wich physically copies the value from one year to the next year based on some other rules in the cube.
Now I need to make this example work with SSAS and Excel PivotTables but I cant figure out how.
I have absolutely no clue where and how to accomplish it. Do I use Calculations, do I use Actions, do i make it in the Dataview, Cube or directly in Excel?
As u can see there is two company references in my fact table, and the schema is in snowflake. My customer requirements state that the Contracts' amounts can be aggregated/filtered for/by, ServiceProviderCompany, its city/profession or ClientCompay, its city/profession.
First thing came in to my mind is to dublicate whole dimension structure (one for serviceproviders, one for clients), which i thought that there should be another way around?
I have created a tabular model with VS 2013 Ultimate. I deployed the model several times and everything works great with Power Pivot.
One of the dimension tables, "Age", has an integer field that is null. I updated that column in SSMS to have values, processed the table in VS and the "Age" column now has integer values.
I deployed the model again, connected with Power Pivot, and the "Age" column still has not data. I refreshed the Excel spreadsheet several times, started a new one, deployed several times and there is still not data in the "Age" column even though it clearly exists in VS.
I opened SSMS on the Analysis Service and queried the table in question and it also shows no data in the Age column even though it is in the data table and the VS model.
I can't find anything different about this column than others that contain data. How can this be happening?
I am facing a very weird issue in our SSAS database. We have several roles with 'Read definition' access. None of these roles are able to see data in the cubes. I have checked these roles over and over and there is no problem with the definition. Each of the roles have been given read access to Data Source, Cube and Dimensions.
The users are able to access the definition and structure of the cube i.e. they can see the measures & dimensions available but when they drag measures and dimension attributes in the browser (SSMS) OR execute an MDX - they get null values. The roles with 'Full Control (administrator)' access are able to see all the data without any issues.
I have tried the following:
1. Deleted all roles and re-created. 2. Created roles directly on SSAS DB. 3. Deployed all objects and processed the DB.
Each time only the admins are able to see the data.
I have a time dimension which has Date, Week, Month and Year. However, the hierarchy will have only Week, Month and Year. It works great for any Sales measure with AggregateFunction as SUM.
I have created a new measure with AggregateFunction = LastNonEmpty. Also in the backend, I have pushed all the inventory data to last date in every month as inventory is always looked on a monthly basis not on a weekly basis. This measure shows correct data for every last week of the month in the hierarchy. However, Months and Years are displayed as zeros.
I would like to build an SSRS report from two different cubes (SSAS 2005). These cubes are contained in two different SSAS databases.
To do this, i created a dataset for each cube throught MDX expressions. These datasets use common parameters defined in my report. Thus, i try to integrate in my report chart datas from the two datasets, but my chart only target one dataset.
Is it possible to create a kind of dataset view to join my two datasets ? Or is it possible to join the cubes from two different SSAS databases in an MDX expression to put all my datas in a single dataset ?
I am trying to implement data masking based on user login and not sure why this is not working. I have the dimensions DimBrand, DimProduct and DimUser. I should mask the BrandCode with 'XXXX' nothing but in the report all the BrandCode should appear but few of the code will be masked if the user is not belongs to that group. I have a fact table FactProduct in this. In the cube I created all these 3 dimensions and the fact table. I created a new dimension DimBrandMask and I separated the code over there with a relationship with the actual DimBrand dimension. In the cube a reference relationship is set up with the measure group. Created a role with read access.
In the dimension data tab of role I put the below MDX to allowed set.
I never got an answer on this so I am reposting this issue. Also, please note that I have consistently reproduced this issue on multiple perspectives within and accross multiple cubes on 3 different SQL Server Instances. I have also had no problem with perspectives within Report Models that were not generated from an SSAS Cube.
Specifics:
=========
I have created a simple cube in BI Studio against an Oracle Relational Data Warehouse. In this cube I have created a perspective in which I have selected (included) only a small subset of measures and dimension. When I view this perspective on the Browse Tab of BI Studio, only the entities that were included in the perspective were available for report construction as was expected.
Next, I generated a model for this cube in Report Manager. Now here is the problem, I then opended the model in Report Builder and selected the same perspective from above, but all of the Entities in the cube were displayed including the fields I explicitely did not include in the perspective. I then looked at the .smdl file describing the Model and it looked like in the Perspective description section all of the cube's entities were included, even the ones that should not have been included. It seems as if the problem is ocurring durring the model generation. I also tried generating the model in Management Studio and it seems to be doing the same thing.
Any ideas on how to fix this? Could I be doing something wrong(probably)? I have to give a presentation soon and this is a big deal for the Project Stakeholders.
By the way, I am using the 180 Day Evaluation of Sql Server 2005 with SP2 CTP installed.
I have a very small SSAS database with around 35 Mb. I opened it on Excel 32 bits and started dragging fields to a pivot table and it started failing with memory errors. The behavior on the SSAS server was that memory started growing very fast until 8 GB (vm memory total) and then the error is reported in excel.
What might be the issue in such a small database? I would understand in a big database, but not on this one.
I am working on datawarehouse using sql server analysis manager. I created a cube ..that is working fine but now i have to distribute to end users so how to do it and how many ways we can do that
1)can we make that .cub file 2)how can give access to endusers without giving access to database 3)how to host a cube and access from excel or any other software
How to get data from cubes in analyses manager to MS access using forexample ODBC ? Does existe any other posibilities to get data from cubesdirectly to the accees ?thanksKris
I work with 2 cubes on live and one for development. I've set the roles in the live cube (using SQL Server management studio). If i go to the design mode of the cube the new roles are not there, so deploying the cube will not update the development cube with the roles. How one can easily copy roles between cubes. (adding them manually would be a lot of work because there are quite a lot of different roles).
I am trying to select from 2 cubes. in one condition - select .. From CubeX, and in sec Condition Select .. From CubeY.
I tried to put the name of the Cube as parameter: SELECT ... FROM @CurrentCube
in ssrs source and i got the message: ------------------------------ Failed to parse the query to detect if it is MDX or DMX. Error: 'Query (148, 6) Parser: The syntax for '@CurrentCube' is incorrect.' (MDXQueryGenerator) ------------------------------
Also tried to get the name of the Cube as Member (I have a property with the name of the cube),and than using the member to the select :
WITH MEMBER [CurrentCube] AS ...[dim name].CURRENTMEMBER.PROPERTIES("Cube") SELECT ... FROM [CurrentCube]
It didnt work too.. Is it Possible at all make the Cube-name dynamic?!
I have some questions about SQL Servers 2000 and 2005 compatibility. In my configuration I have to use both servers. The cubes are stocked in 2005 server. 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?
How can I UNION two MDX query results which are deriving from 2 cubes?MDX queries will return same ROW information and only Measure names will be different.
