HI,
What type bad Data coming.
Example :- VBAP & VBUP ECC table has ERDATE ( Created on ) field. This filed is very critical because of we are mapped all time character field in BW Transformation. ( Ex- 0Calday mapped with ERDATE)
If ERDATE data will come blank or 00//00/0000 BW DTP will fail but not give red status request. In this case need to find record no after correct date in PSA & ECC end.
After load data in BW.
I hope this will helps.
Thanks
