Remove batch number on delivery. Maybe using BAPI_OUTB_DELIVERY_CHANGE / WS_DELIVERY_UPDATE_2

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.
