[BergOff]

Hi, experts.
How to add an item to delivery using  'WS_DELIVERY_UPDATE_2' ?
I found only how to delete, but don't understand how to add a new one.

     vbpok_ls-vbeln_vl = ls_delivery_item-vbeln.
     vbpok_ls-posnr_vl = ls_delivery_item-posnr.
     vbpok_ls-lips_del = 'X'.
     APPEND vbpok_ls TO vbpok_lt.


   vbpok_ls-vbeln_vl = ls_delivery_item-vbeln.
   vbpok_ls-posnr_vl = '000040'..
   vbpok_ls-matnr = '4101-80020-00299'.
   vbpok_ls-charg = '0017475744'.
   vbpok_ls-lfimg = 8.
   APPEND vbpok_ls TO vbpok_lt.

call function 'WS_DELIVERY_UPDATE_2'
  exporting
    VBKOK_WA                           = vbkok_ls
    COMMIT                             = 'X'
    DELIVERY                           = ps_expand-vbeln
    UPDATE_PICKING                     = 'X'
    NICHT_SPERREN_1                    = 'X'
    IF_DATABASE_UPDATE_1               = '1'
 IMPORTING
    EF_ERROR_ANY                       = ef_error_any

Hello @BergOff 

I can't answer you question directly as WS_DELIVERY_UPDATE_2 is not documented. As it is really by trial and error you can figure out the correct way to call the function. 

But there is a indirect approach via Delivery Interface i.e. WHSCON IDoc. As per SAP Help the IDoc can report batch split items:

You can build a test WHSCON IDoc in WE19 and verify that it updates a delivery the way you want. The IDocs are posted with the WS_DELIVERY_UPDATE_2 function. So you can put a breakpoint in the function and check how the IDoc data are communicated to the function. This will show you have to call the function to add a deliver split item.
