All,
IF you get this type of Error check bad data coming From ECC.
EXAMPLE - VBAP / VBUP Table in ECC has ERDATE ( Created On). This field is important and we are mapped in Sales DSO with Time Character ( Ex Calday etc).
If this Date will come blank or 00/00/0000 than BW transformation time character will not convert in date after will get SYSM: Date 00/00/0000 or 00/01/0000 type error.
In this case correct date in PSA or ECC after load in in BW.
This will help lot...
Thanks
