How to remove batch number on delivery? - abap

Question

I need to remove the batch number (LIPS-CHARG) on the delivery item and tried with BAPI_OUTB_DELIVERY_CHANGE without success.
I can change the delivery quantity (LIPS-LFIMG) correctly with this BAPI and change the picking number (LIPS-PKIMG) with WS_DELIVERY_UPDATE_2, but can't remove the batch number.
Does someone already remove the batch number? Don't need to use this BAPI, can be another one. I just need to remove the batch in any way.
The following code works to change the delivery quantity and picking quantity. At a certain moment, I change picking quantity to zero and at this moment I need to remove the batch number.

Answer 1

I found my error!
When we need to remove the batch number, we don't need to send value on ITEM_DATA-DELIV_ITEM.
In my code, I was sending '90000001' on ITEM_DATA-DELIV_ITEM and '00010' on ITEM_DATA-USEHIERITM, but to work I just send ITEM_DATA-USEHIERITM and the batch number was removed correctly.
Thanks all!
