Partial refunds in BAPI_GOODSMVT_CREATE

Hi All,

I want to make a partial refund in a PO but I don't know how to!

For example, I want to refund positions 5 and 6 of this PO. I am using  BAPI_GOODSMVT_CREATE, but in the table  goodsmvt_item, only allows me to enter one item, but I need, in this case, to refund more than 1 item.

In the example attached, I try to refund 12, (marked in positions 5 and 6). If i enter in goodsmvt_item-entry_qty = 6, it works fine, but refunds me only one item (6, I mean). If I place goodsmvt_item-entry_qty = 12, the bapi returns me the message M7 021 Deficit of Project stock unr. 6,00 PC : XXXXXXX XXXX #### Q

By the way, I am using 932 movement type

Please, can anyone help me about this issue?

Thanks in advance,

Mario
