Why is my SSRS report showing old data?

Question

I have a live report that\'s somehow showing cached data despite the fact that I\'ve disabled all caching (that I\'m aware of). When I run the query in the BIDS query editor

Answer 1

Old post, but I still run into this, and found an article on how to put an option under external tools to make this easier.

1. Go to Tools > External Tools...
2. Add a new tool with the following settings:
   • Title: Clear Report Data Cache
   • Command: "%WinDir%\System32\cmd.exe"
   • Arguments: /C DEL /S /Q "$(SolutionDir)\*.rdl.data"
   • Check options: Use Output window & Close on exit

Now whenever you want to delete your report data cache, just go to Tools > Clear Report Data Cache
