I create with success powerpivot cube. But after fwee days, I can no more refresh one table. I receive error message:
Errors in the high-level relational engine. The following exception occurred while the managed IDataReader interface was being used: '?', hexadecimal value 0x1C, is an invalid character. Line 92054, position 26..
The operation has been cancelled.
This table come from Data Feed List Sharepoint. I think that no new field has been added or modified from the list.
