Problem with BBP_PD_PO_UPDATE and BADI BBP_DOC_CHANGE_BADI

Hello,

I've found out the following issue in SRM 7.0: during the run-time of the FM BBP_PD_PO_UPDATE in the program or BAdI something strange happens instead of the standard change of the DB:

- the updated data appear as a result after the running of the FM BBP_PD_PO_GETDETAIL in the program

- the old, pre-updated data appear as a result after the running of the FM BBP_PD_PO_GETDETAIL in the TA SE37.

It looks like an issue in the SAP code, but I've found no OSS-Note.

Could you please give me an advice regarding the difference in the program's behaviour depending the way of running (in background or dialog mode).
