sample code :
Here is some sample code from one of my programs, which does a 551 movement type. This should get you started. Just check the RETURN table for messages, they should tell you what you are missing.
* Structures for BAPI
data: gm_header type bapi2017_gm_head_01.
data: gm_code type bapi2017_gm_code.
data: gm_headret type bapi2017_gm_head_ret.
data: gm_item type table of bapi2017_gm_item_create with header line.
data: gm_return type bapiret2 occurs 0.
data: gm_retmtd type bapi2017_gm_head_ret-mat_doc.
clear: gm_return, gm_retmtd.
refresh gm_return.
* Setup BAPI header data.
gm_header-pstng_date = sy-datum.
gm_header-doc_date = sy-datum.
gm_code-gm_code = '06'. " MB11
* Write 551 movement to table
clear gm_item. move '551' to gm_item-move_type .
move '000000000040001234' to gm_item-material.
move '1' to gm_item-entry_qnt.
move 'EA' to gm_item-entry_uom.
move '0004' to gm_item-plant.
move '4000' to gm_item-stge_loc.
move '201' to gm_item-move_reas.
* Determine cost center per plant case xresb-werks.
when '0004'.
move '0000041430' to gm_item-costcenter.
when '0006'.
move '0000041630' to gm_item-costcenter.
when '0007'.
move '0000041731' to gm_item-costcenter.
when '0008'. move '0000041830' to gm_item-costcenter.
endcase.
append gm_item.
* Call goods movement BAPI
call function 'BAPI_GOODSMVT_CREATE'
exporting
goodsmvt_header = gm_header
goodsmvt_code = gm_code
importing
goodsmvt_headret = gm_headret
materialdocument = gm_retmtd
tables
goodsmvt_item = gm_item
return = gm_return.
call function 'BAPI_TRANSACTION_COMMIT'
exporting
wait = 'X'.
