The SAP error message /IWBEP/SBOD221 Map '&1' to ABAP TIMESTAMP for dates b.c. and in year 0 typically occurs when there is an issue with date handling in the context of ABAP and the SAP Gateway. This error is related to the mapping of dates that are either before Christ (B.C.) or in the year 0, which are not supported by the standard ABAP date and timestamp formats.
Cause: Date Format Limitations: ABAP's date handling does not support dates before the Gregorian calendar (i.e., B.C. dates) or the year 0. The ABAP date format is based on the Gregorian calendar, which starts from year 1 A.D. Data Input: The error may arise from data being sent to the SAP system that includes invalid date formats or values that fall outside the supported range. Mapping Issues: The error can also occur during the mapping process in OData services where the date values are being converted
