Update Pick Quantity in the Outbound Delivery
Many already know, the FM to be used for this purpose is WS_DELIVERY_UPDATE_2. It comes with its own share of mysteries.
First, there is no picking quantity in the LIPS table, so we know picking quantity can not be just directly modified using BAPI_OUTB_DELIVERY_CHANGE. Here is a very simple code sample explaining how to use WS_DELIVERY_UPDATE_2.
ls_header-vbeln_vl = <deliverynumber>.
ls_vbpok-vbeln_vl = <deliverynumber>.
ls_vbpok-posnr_vl = <deliveryitem>.
ls_vbpok-vbeln = <mostlydeliverynumber>. "Can be other reference document as well
ls_vbpok-posnn = <relatedlineitem>. "If using delivery number, then use the same delivery item as before
ls_vbpok-taqui = abap_true.
ls_vbpok-lfimg = <quantity>. "It is good idea to provide the unit as well but not mandatory
APPEND ls_vbpok TO lt_vbpok.
REFRESH lt_return.
CALL FUNCTION 'WS_DELIVERY_UPDATE_2'
EXPORTING
vbkok_wa = ls_header
synchron = abap_true
commit = abap_true
delivery = <deliverynumber>
update_picking = abap_true
if_error_messages_send = ''
TABLES
vbpok_tab = lt_vbpok
prot = lt_return.Some pointers to note here:
- Picking quantity is not added to the previous picked quantity. So you need to do the calculation in your program logic.
- If you getting the error – “Picking request not yet confirmed” VL618 during PGI, then you may need to check the flag – TAQUI in VBPOK (item data). Please note, you may want to do this only when full picking for that line item is done.
- While using in the program, you may want to set the if_error_messages_send flag as “blank”. Otherwise, the program will stop if some error is encountered by the FM.
- No need of separate commit.
This function module can also be used for picking WM material (picking and packing). More about them later.
