Goods Receipt by Inbound Delivery - BAPI_GOODS_MVT

Hi All,

I try to use BAPI_GOODS_MVT bapi to move goods by inbound delivery number. According to MIGO transaction, I send all necessary fields to bapi. But somehow I get error. However I know it is possible to make goods movement manually with MIGO transaction with following parameters, but when it comes to terms using bapi, i get error:

pstng_date

gm " 01

plant

move_type " 101

entry_qnt

po_number

po_item

mvt_ind " B

deliv_numb

deliv_item

Error :

Delivery quantity exceeded by XX PC : XXXXX 0001 0001

Am I missing something?
