Report Dataset is lost once the Data Tab is clicked

1. Created a New Report Server Wizard Project using OLAP as datasource
2. Gone through the wizard steps to generate a matrix report.
3. All is fine and the report gets previewed. I build and deploy the report.
4. Now , if I need to add a new column I go to data tab of the report. Realize that the query is lost and now the report throws exception like the following when rebuild:

" [rsFieldReference] The Value expression for the textbox ‘Base_Premium’ refers to the field ‘Base_Premium’. Report item expressions can only refer to fields within the current data set scope or, if inside an aggregate, the specified data set scope."
5. No idea why the query given at the query builder stage of the wizard is lost

Steps to Reproduce:

1. Create a new Report Server Wizard Project
2. Create a new datasource using OLAP as datasource
3. Add the report data fields (query builder)
4. Select matrix report format and any style
5. Select the row, col and data fields.
6. complete the wizard.
7. Save, build and deploy the project
8. Preview the report.
9. Now try to add a new column to the report by clicking the data tab.

Actual Results:

The sql prepared from the query builder is lost and all the columns previously selected disappear. The report throws exception in preview mode something like :

" [rsFieldReference] The Value expression for the textbox ‘Base_Premium’ refers to the field ‘Base_Premium’. Report item expressions can only refer to fields within the current data set scope or, if inside an aggregate, the specified data set scope."

Expected Results:

Should be able to modify the report any number of times after it is initially generated.

Report Builder Connection Error

Okay, here is the scenario. I have an analysis services cube and a report
model generated from a OLAP datasource in reporting services. My first
problem is that when I try to create a report using the report builder from
my local pc I get data source connection errors, but if I remote desktop into
the dev server where reporting services is installed an complete the same
procedure everything works great. My second problem is that I cannot create
a report model from an OLAP datasource unless I am remoted into the report
server.
Thanks, Andrewwhen you create report model, you need to use default in your data source
properties, so that it takes the same and connects.
second problem is: have you deployed your report model, only then you can
see the entities and then you can create the reports.

> Thanks, Andrew|||When I navigate to my OLAP datasource using SQL Server Management Studio and
generate the model my datasource security is set to windows integrated
security. The OLAP datasource impersonation information is set to use the
service account; when I do this from SSMS on my local laptop I get connection
errors, but if I remote desktop into the reporting services server and
connect to reporting services using the SSMS it will create the model and you
can create and run a report from the report builder no problem.
