Performance issue with BAPI_ACC_DOCUMENT_POST

Hello All,

Does anyone know or have experienced any performance issue with BAPI_ACC_DOCUMENT_POST?

I'm using this bapi ABAP code but is very slow, each document posting takes almost up to 1,4 minutes.

Each document contain 998 line items (debit and credit).

This program run a batch job. I'm posting 38 documents on an average takes up to 55 minutes.

After the posting, the program checking the processing message returned by the BAPI.

Would something have to be done in this situation or would it be necessary to parallelize this part of the code?

So how to implement multiple BAPI calls (parallelism). Have you any idea? May be another approach?

Thanks in advance,
