I have to create an API (odata) through which I have to update delivery with Batch number , Pick quantity and unit. I want to change all 3 field by one BAPI or FM. I already checked WS_DELIVERY_UPDATE_2 which will update pick quantity and unit but not batch and if we go for BAPI_OUTB_DELIVERY_CHANGE than there is no field for pick quantity and unit only we can update Batch through this BAPI. FM WS_DELIVERY_UPDATE_2 is getting called inside BAPI BAPI_OUTB_DELIVERY_CHANGE but the pick quantity field is not available in the BAPI. Anyone if help me on this.
