WIS 10901 error while running WEBI report

Hello All

When we try to run WEBI report on BW query for Cost center accounting infocube its giving following error when we add measure in the info view.

"A database error occured. The database text is: Error in MDDataSetBW.GetCellData. See RFC trace file or SAP system log for more details. (WIS 10901)"

We did a trace and came to know that BO user id doesnt have authorization for Admin work bench. But when we authorize too its giving same error.

This error populates only when we drag measure into the info view of Webi and if we drag any characteristic it works fine.

Any help is highy appreciated.

Thanks
