Forum Post: RE: Management Reporter 2012 CU12 Data Mart Refresh (GP connector) - String or binary data would be truncated GL Transaction to Fact Task fails

HI 26P2ER (?), CU12 was not the most stable release of MR 2012.. I would strongly suggest to upgrade to CU14 at least. The latest build CU15 has been release recently, but requires some other significant changes to your server (.NET upgrade).
