If I open up SSRS and edit a report through the Report Builder, any changes I make are not reflected when the report is exported as part of a solution. The changes do show up when I run the report.
Simple way to reproduce:
Create a new report in CRM using the report wizard, choose any entity.
Add a single column, for any field.
Save and publish the report to the organization.
Find the report on the SSRS page and select "Edit in Report Builder".
Change anything about the report, for example the column heading, and save. You will notice that running the report in CRM shows the changes.
Publish all customizations just to make sure.
Create a new solution, add the report to it, and export the solution. The exported report does not contain the changes. You can see this by either importing the solution, or unzipping the solution and editing the report itself directly in BIDS or Notepad.
Is this a bug, or am I doing something wrong? Editing the report in the report wizard, or by using BIDS, does not have this problem.
