How to change connection string of a pivot table pointing to SSAS 2005 cube using excel 2003?

Posted By:      Posted Date: September 02, 2010    Points: 0   Category :Sql Server
Hi All,I am not sure if I should have posted this query to Excel 2003 forum. But posting it here as it applies to SSAS 2005 as well.Ok, let me give the background before I tell the actual problem.We have users on ABC domain and the SSAS server is also on ABC domain. Users on this domain can acess the excel pivots by connecting to cube to browse the data. They leave the Userid & password field blank while they setup the connection string and it works fine. Thanks to windows authentication that takes the credentials of user logged in. Let's say I have two users A and B, they login to ABC domain with their own windows ids.  Now when user A creates a excel file having a cube pivot and then sends this file to user B, user B can refresh and modify the same excel file (he can select new measures to pivot, new hierarchies in filters and so on).Now, let's say I have another user, user C. He has excel 2003 installed on his PC and cannot migrate to excel 2007. He is on different domain XYZ but have a valid windows userid on domain ABC. The domain ABC & XYZ can not be setup to have trusted relationship. Now, when user A sends the same excel file to user C. When user C opens the file and try to refresh it or try to modify the pivot by selecting/deselecting any elements, he gets below error prompt:" An error was encountered in the transport layer." and "Errors in the

SSAS 2008 R2 Cube being queried by Excel 2010 Pivot Table - 60x slower than with Excel 2003!


SQLServer 2008 R2

Excel 2010 x64

Hi All,

I have a fairly complex Excel report where a raw data sheet is updated from 10 or so PivotTables pulling from an Analysis Services Cube, (2008 R2), with a VBA script that refreshes all pivottables, and then does some post-processing, formatting etc.

This was originally developed in Excel 2003, and the updating of all the pivot tables ran in under 10 seconds

I've now recreated in Excel 2010 and *each table* is taking up to a minute to refresh!

I've also observed that I can get the refresh time of a single table back down to 1sec, if I delete all other pivottables from the worksheet/book.

Its deeply frustrating, as I'm touting 2010 as being the way for our business to go...it won't help the cause if I deliver something with a x60 increase in runtime!

I've run traces of both the 2003 and 2010 versions executing against the SQL Server, the only thing I can see is that the 2003 version passes 1 single MDX query, whilst the 2010 version appears to be firing it in sections.

I've posted this in the Excel forum too.

Please can anyone help?

Many thanks,





With Excel pivot table client using SSAS cube, how to change the measures to rows?

SSAS Cube & Pivot table

Hello, I am connecting to my SSAS cube through excel Pivot table. I have the following questions: 1) I have a filter for Company. However, instead of selecting multiple companies from a drop down list, I would like to have a range e.g. Company between 100 and 200. We have this "Filter expression and operator" option in SSAS but I dont see in excel. 2) I have 90 users who will be using my cube via pivot tables. How do I automatically have the data in excel refresh automatically such that when the user comes in, in the morning and open the pivot table, they have the refreshed data. Instead of them manually refresh it as it runs the query for a long time. Thanks in advance for all your help and suggestions! KJ

Excel 2007 Pivot table OLAP- SSAS 2008 Error

Hi, I do have a strange issue with Excel 2007 pivot table report; the data source is SSAS 2008 cube. When refresh the excel 2007 report data using the 'Refresh All' or 'Refresh' button available under the Data menu, the below error is thrown. "The expression contains a function that cannot operate on a set with more than 4,294,967,296 tuples." After some analysis, the report works well on the below workaround, 1. Remove all the calculated measures from report (3 measures in this scenario) 2. Remove one row label (dimension attribute) from report But the measures, attributes are valid one from cube and it is required fields in the report. So, understand that removing few items is not at all a solution. The below workaround also works. 1. Check the 'Defer Layout Update' option from the Pivot Table Field List window. 2. Click on the Update button After that Unchecked the 'Defer Layout Update' option and apply the filter, etc in the report. The report works very well. But every time, we need to use the above work around after open the excel report. I have NO clue on this issue. Please help to resolve this issue. Thanks, Jey

Excel 2003 pivot table - parent showing grand total than the sum of its children

All, In Excel 2003, I have a product hierarchy, for simplistic sake lets say it goes A > B > C > model nbr.  I have filtered on model nbr 1.  I have the product hierarchy in my pivot table and unit cnt as the measure. Starting at level A in the hierarchy I am showing a total unit of 12000, if I drill down to B it still shows 12000, if I drill down to C it shows 100 and if I drill down to model nbr it shows me model nbr 1 with a unit cnt of 100. So my question is why are my parents not filtering the model nbr, it is taking the total for ALL records that have level A as their parent regardless of the model nbr? This does NOT happen in Excel 2007 or when I browse my cube in SSAS.

Excel 2007 connectivity to SSAS 2005 cube

Hello - I am using an excel 2007 odc file to connect to an analysis services 2005 cube (on windows server 2003 R2 OS). I receive the following error message   "Excel was unable to get necessary information about this cube. The cube might have been reorganized or changed on the server" Have already attempted the following fixes but running out of ideas now 1. Added localeIdentifier to ODC file    <odc:ConnectionString>Provider=MSOLAP.3;Integrated Security=SSPI;Persist Security Info=True;Data Source=bisql;Initial Catalog=SLAM ACT BUD; LocaleIdentifier = 1033 </odc:ConnectionString> 2. Ensured that all dimensional attributes which are used in MDX calculations (named sets, calculated members) are set to "AttributeHierarchyEnabled  = True" Running out of steam so any help is greatly appreciated.

Excel pivot table report filter selections from a cube

There are two filters added to the report filter, Date (8/31/2010) and Product (Product A), from a cube I have.  Everything works just fine.  Once the cube is refreshed each day to include the new data, for some reason, only the selection of Date, 8/31/2010, stays but the selection of Product changes to All Products.  Both dimensions are fully processed but the surrogate keys for existing records do not change.  I checked the MDX captured in Profiler and in the where clause, the date selection is passed from the pivot table but the product selection is lost and all products is passed in.  Any thoughts? TIA. 

Users use Excel-Pivot table to query the cube, how to capture those queries?


Most of our users use Excel'10 for querying the cube,

I've set up the querylog-properties in SSAS engine but it only captures the query from SSAS engine and not from the other platform such as Excel. So, when I use Usage based aggregation wizard, it shows the users/ueries from SSAS engine only. Is there any way to capture the user/query information that comes through Excel pivot table and somehow create aggregation through that information?


Any suggestion/help is very much appreciated,


Check the if SSAS Roles property is used in excel connection string before returning the values



We are using Excel 2007 to connect to SSAS cubes. We have many roles for a user and all having different permission including different VISUAL TOTAL setting. We want to restrict the user so that he cannot see anything if he is not using the ROLES property in the excel connection string.

At the run time I want to know if the user who is using excel has used ROLES property or not.

Any help will be appreciated

excel pivot table linked to cube, unable to expand/collaps single field


I’m re-posting question. I’m using excel pivot table to browse a cube, for example the adventuresworks example. I drag dimension ‘Product Categories’ and ‘Sales Territory’ to Row Labels area, a date dimension to column, and any measure to Values area. Now I only want to expand ‘Europe’ under ‘Bikes’, but the excel  will expand ‘Europe’ under every ‘Product Categories’, is there any way to avoid that? In visual studio it works fine.

Font didn't change in excel, after change was made on SSAS

Change connection string of Linq to Sql entities

Hi all.I have a solution which uses Linq to SQL Data Classes to acced the db. I have a project for my domain objects in my solution, which is a class library and has the dbml file. When I set up the dmbl using the wizard, Visual Studio created an app.config file on that project with the connection string. It also creatting a settings file with the same info. I've noticed that if I change the connection string in the settings file, the app.config gets updated, which is the expected behaviour.However, I'm having a problem when I deploy my web site to the production server. I already set the app.config file's Build Action to "Content", and also set Copy to ouput directory to "Always". Nevertheless, when I install the web site and change the connection string in the app.config file, it still takes the old connection string, so obviously I get an error. I've found that it only works if I change it with in Visual Studio and then compile, but of course that's not an optimal solution, because any change in the production db server would mean I have to change my project's assembly, thus generating a new version.Any thing I'm missing? What do I have to configure so that the assembly takes the connection string form my app.config file directly after I deploy?Thanks a lot.

Range or List Filtering via SSAS cube in Excel 2007

Hi All, A client has posed an interesting question, as current users of business objects webi they can filter the results of a cube/universe by copy and pasting a range or list of values seperated by a ';' into a list filter that is availble. e.g. product2;product533,;product029;product8389 etc etc. The list can sometimes be hundreds long. How is that same function acheived in browsing a ssas cube in excel 2007, all I can see is that a user has to use the drop down list and individualy select the values they want. This does not seem like a great method! Any ideas? They are using SQL / SSAS/ SSIS/ SSRS 2008 R2 Cheers DC

SQL Server 2005 Analysis Services - Performance of Excel Pivot Tables

Hi, I've several cubes available for several users within my organization. I've the SQL Server 2005 and the Analysis Services running on the same machine but it has 30Gb of RAM, 8 processors and a quick enouth disk. The problems is that i've some automatic processes that "build" some excel reports and the users use pivot tables with olap connections to the cubes regularly. I've noticed that the excel "locks" when the user is drilling down the data and the server has only one processor (there are 8...) at 100%... Is there a way to make the analysis services use the maximum processing capacity that is available? The users are complaining about the slowness of the cubes... Thanks in advance Hugo
