BAPI BAPI_GOODSMVT_CREATE, the document flow is not updated for the outbound delivery.

Hi, we have SAP Retail (ECC 6.0). We´re implementing Intercompany PO Process, every works fine except the GR with outbound delivery.

We´re using the BAPI BAPI_GOODSMVT_CREATE to Post the Goods Receipt and the document flow is not updated for the outbound delivery.

We´re using the following parameters for calling BAPI

"-----------------------------------------
" LLENAR DATOS GOODSMVT_HEADER
"-----------------------------------------
xbapi2093_res_head-pstng_date = budat.
xbapi2093_res_head-doc_date = bldat.
xbapi2093_res_head-ref_doc_no = delivery. "vbeln.


"---------------------------------------
" LLENAR DATOS GOODSMVT_CODE
"---------------------------------------
xbapi2017_gm_code-gm_code = '01'.


"-------------------------------------
" LLENAR DATOS GOODSMVT_ITEM

'10' TO xbapi2017_gm_item_create-deliv_item_to_search, "posnr
'B' TO xbapi2017_gm_item_create-mvt_ind.

APPEND xbapi2017_gm_item_create.

IF xbapiret-type EQ 'S' OR xbapi2017_gm_head_ret-mat_doc <> ''.

CALL FUNCTION 'BAPI_TRANSACTION_COMMIT'

Why not update the document flow for the outbound delivery?

Thanks and advance
