I was trying to run a book and received this error:
"Column A on grid "Grid 1" has a reference to a Member "&QTDCurr" in dimension "Time Periods" which was not found in data source "PandL"
This book only has one report and I opened the report to check it. There is no "Grid 1" in this report.
I opened some of the other reports and some of them did have "Grid 1".
I checked Column A and some of them did have the subvar &QTDCurr.
