Problem for BAPI2017_GM_ITEM_CREATE

Hi all,

I'm using FM "BAPI2017_GM_ITEM_CREATE" to create a material document for transfer posting.

After calling the FM, the FM returns a material document no. and the document year without error, but when I use MB03 to verify the material document created by the FM, the material document is not displayed. And the db table MSEG has no entry for the mat. doc with mat. year too.

I just don't know which part I got wrong...

Could anybody help ? Thanks.
