We are working on migrating our SSRS from SQL Server 2008 to SQL Server 2014. After brining the reports over I have a set of reports that will execute just fine but when I try to perform a standard export to excel from the 2014 Server I get a message box saying:
We found a problem with some content in ACM Consolidated Invoie_2014.xlsx. Do you want us to recover as much as we can? If you trust the source of this workbook, click yes.
However, I do not receive the same message when exporting to Excel from the 2008 server. I believe the problem is related to some Numeric fields that are coming back with a value of 0.0000000000000000000. Has something changed with the excel export function between these two versions?
