Refresh Table failed due to invalid character RRS feed

  • Question

  • Hi,

    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. 

    Any Idee ? Thank's in advance.

  • I found the error. One column contains invalid character Hexa 0x1C

    To find the Sharepoint item in error. I export all items in Excel than copy in convert application like notepad++ plugin Hexa convertor.

    Find the item and replace the character.

    Hope this could help some one else
