About BAPI_PRODORDCONF_CREATE_TT and releasing Reservation

Dear Friends at SCN,

I have the following problem when using the bapi BAPI_PRODORDCONF_CREATE_TT, that is called several times in the same program:

the first run completes successfully, and then there is a call to BAPI_TRANSACTION_COMMIT.

with the second, and the remaining ones, usually the BAPI returns an error saying 'Reservation xxxxx is already being processed'.

I believe I should release the Reservation, after the first bapi call, and before the next one, but how to achieve that?

Do you have a clue how to avoid this error appearing?

Thanks a lot for any help or suggestion on this.

Bye,

Flavio
