Issues Loading data Asset Accounting

Hello All

I am trying to load Asset Accounting with delta extraction, and am having issues.

I am using 0FI_AA_11 and 0FI_AA_12 as sources and have the FIAA_BW_DELTA_UPDATE active in the source system.

I can do a full load of both sources to ODS and Cube without issue. I can Do an Intialization without data transfer from both sources to ODS and Cube without issue, but once that is done I can not do a delta transfer. I get an error message: "Error in Source System"

I get the same error when I attempt to do an Initialzation with data transfer. I am not sure what else to try and how to trouble shoot this problem.

Any assistance is greatly appreciated.
