Diagnosis

You use Node components with data type SSTRING (Character string) for an Alternative Key definition. Either as part of a structured Alternative Key or as line type.

System Response

The BOPF runtime shows "unexpected behavior" in key conversion (and other functions) in case SSTRING-based data is handed over with trailing spaces.

Root cause is, that a SSTRING-based value is "right trimmed" once it gets stored in the database, so that subsequent comparisons in ABAP will fail. In detail the comparisons fail in the BOPF data access layer (DAC) and in the BOPF buffer.

Procedure

Do not use Node components with data type SSTRING for an Alternative Key definition. Neither as part of a structured Alternative Key nor as line type.

If you require a SSTRING-based Node component for an Alternative Key definition, you must change the data type from SSTRING to CHAR.

If the change from SSTRING to CHAR is not possible, make sure, that your application hands over the SSTRING-based data to BOPF without trailing spaces! In detail make sure, that all calls to the BOPF services CONVERT_ALTERN_KEY, MODIFY, ... provide no trailing spaces in the SSTRING-based components of the importing parameters IT_KEY, IT_MODIFICATION-DATA, ...!
