Hi team,
When trying to upload an rdl to SSRS, I get a "The definition of this report is not valid or supported by this version of Reporting Services. The report definition may have been created with a later version of Reporting Services, or contain content that is not well-formed or not valid based on Reporting Services schemas. Details: The report definition has an invalid target namespace. (rsInvalidReportDefinition)"
My current environment is SQL 2014 on one server and SQL2008R2 on another server. Running Report Builder 3.0 SQL 2008R2.
What I've done to troubleshoot and try to open and upload 11 reports:
I initially installed Report Builder 3.0 SQL2014 to open the rdl reports. Since I wasn't able to open in Report Builder 3.0 SQL2014, I uninstalled that and installed Report Builder 3.0 SQL 2008R2. I was then able to open 2 reports.
I also tried to change out the report header from 2016 to 2010 and 2008, but no luck. (couldn't supply the exact report header on this initial forum as "Body text cannot contain images or links until we are able to verify your account."
I'm out of ideas, so any help is appreciated.
Mark
