Delivery and Shipment handling units
Business Requirement :
1.Creation of Delivery Handling unit for over packing and master cartons even if over packing is not required.
2 Creation of Shipment Handling Unit for boxes packed in Deliveries to allow receipt by HU# in the receiving plants.
Challenges : While creating shipment handling unit, all the delivery handling units are automatically attached to the shipment handling unit and they are deleted from deliveries when the BAPI (BAPI_HU_CREATE) is used. BAPI_HU_CREATE has the parameter LOWER_LEVEL_EXID is present in tables parameter (BAPIHUITEM), however after using this parameter to attach the delivery handling units to Shipment, these handling units are deleted from delivery.
Solution – In order to avoid above issue we had gone ahead of different approach and able to attach the delivery handling units to shipment with correct hierarchy. we need to call the below bapi’s in sequence to achieve the above functionality
head_proposal-hu_status_init = Pass 'A' ."Planned. head_proposal-pack_mat = Pass Packaging Material "Call the below function module to create an Unassigned HU object. CALL FUNCTION 'BAPI_HU_CREATE' EXPORTING headerproposal = _head_proposal IMPORTING huheader = hu_header hukey = hu_key TABLES return = return. IF hu_key IS NOT INITIAL. "Call the below function module to Commit the data CALL FUNCTION 'BAPI_TRANSACTION_COMMIT' EXPORTING wait = 'X' IMPORTING return = return. " Assign to a Shipment hu_header-pack_mat_object = '04'. "04-HU Type for Shipment hu_header-pack_mat_obj_key = Shipment number "Shipment # hu_header-lenght = Pass Pallet length hu_header-width = Pass Pallet Width hu_header-height = Pass Pallet Height hu_header-total_wght = Pass Pallet weight hu_header-unit_dim = Pass Pallet Uom for dimensions hu_header-unit_of_wt = Pallet Uom hu_header-max_unit_of_wght = Pallet Uom. ENDIF. "Call the below function module to assign the handling unit to shipment CALL FUNCTION 'BAPI_HU_CHANGE_HEADER' EXPORTING hukey = hu_key huchanged = hu_header TABLES return = change_return. IF change_return IS INITIAL. "Call the below function module to commit the data by assigning Shipment to Handling Unit CALL FUNCTION 'BAPI_TRANSACTION_COMMIT' EXPORTING wait = 'X' IMPORTING return = return. " Get the Internal Handling unit based on external handling unit and prepare the handling unit numbers (Box_pallet_venum) which needsto be passed to below function module. " The below function module is called for filling the global memory CALL FUNCTION 'HU_GET_HUS' EXPORTING if_lock_hus = co_x if_no_loop = co_x it_venum = box_pallet_venum EXCEPTIONS hus_locked = 1 no_hu_found = 2 fatal_error = 3 OTHERS = 4. "Each and every Internal handling unit (Boxes) to be attached to shipment and the below function module should be called in a loop. packing_request-venum = Hu_header-hu_id. packing_request-exidv = hu_key. packing_request-velin = '3'. packing_request-sub_hu_venum = vekp-venum. packing_request-quantity = '1'. Packing_request-veanz = '1'. " The below function module is called to Repack the deliveries in the shipment which is required for hierarchy in shipment CALL FUNCTION 'HU_PACKING_AND_UNPACKING' EXPORTING if_repack = 'X' is_packing_request = packing_request IMPORTING ef_rcode = return_code CHANGING cs_header = cs_header EXCEPTIONS missing_data = 1 hu_not_changeable = 2 not_possible = 3 customizing = 4 weight = 5 volume = 6 serial_nr = 7 fatal_error = 8 OTHERS = 9. IF sy-subrc EQ 0. " Call the below function module to commit the data by assigning Shipment to Handling Unit CALL FUNCTION 'BAPI_TRANSACTION_COMMIT' EXPORTING wait = 'X' "If the Pallet packing is successful then only call the below function module " The below function module commits the data to database. CALL FUNCTION 'HU_POST' EXPORTING if_commit = 'X' ENDIF.
Negative results – ( when the Bapi Function module (BAPI_HU_CREATE) is used and passing the parameter LOWER_LEVEL_EXID), the output as follows
- Delivery handling units are correctly packed and the hierarchy is correct
2. However when we pack the delivery boxes to shipment the hierarchy is off as shown below. The hierarchy should be ‘0’ for Shipment handling unit,’1′ for delivery handling unit and ‘2’ for material.
Positive results – ( when the Function modules are called in sequence as suggested in the blog)
1.The handling units for delivery are shown below which was successfully attached to delivery
2. HUPAST tcode for handling units with respect to delivery.
3. Handling units with respect to delivery shown below and the important element is the hierarchy (Shipment handling unit comes first , then delivery handling unit and then the packaging materials.
Note : The above usage of FM’S and Bapi’s needs to be called sequentially as shown above to achieve the functionality. The high level code is provided as solution.
