Adding new object type (field BKPF-AWKEY) for BAPI posting

Hi everyone,

I am posting to SAP GL using an input file to read the data and transfer it to BKPF and BSEG tables.

The problem is I have to use BAPI_ACC_DOCUMENT_POST, and it expects values for OBJ_KEY and OBJ_TYPE.. For now, OBJ_TYPE creates a problem, because if I use BKPF, it says it cannot post using this object type, as it is for SAP internal use only.

Does anyone know how to add a new object type for the customer namespace, which can be manually used for this kind of posting? I know that the new entry must be made in tables TTYP, TTYPT, and possibly TTYPV, for which the maintainence view exists: V_TTYPV.

How to add an entry here, or where can I find it in customizing?

All helpful answers will be awarded.

Thank you very much
