Error in BI 7 while loading to Cube from ODS

Hello folks

I am getting the following error messages while loading Cube from ODS using DTP in BI 7. The load is a delta running for the first time.

1) Inconsistent input parameter (parameter: <unknown>, value <unknown>) - Message no. RS_EXCEPTION101

2) Error while extracting from source YSDOBILL (type DataStore) - Message no. RSBK242.

This is a production issue. So, any help in this regards will be appreciated and points will be assigned.

Thanks,

Rishi
