Managing Work Orders with Serialized Items and Quantity Greater Than One

Purpose

This procedure guides the management of manufacturing work orders involving multiple serial numbers.

Before you start

Before proceeding, ensure the following prerequisites are met:
  • A work order (WO) is created without serial numbers, and the quantity is greater than one.
  • The WO type in 'Work Order Type. Open' (MOS120) must have setting 100 (Update material plan=1), and parameter 160 must be enabled to update the header quantity based on operation quantity.

Expected outcome

Serialized items are created, stocked with the correct cost, and the cost is distributed among the quantity.

Procedure

  1. Open 'Work Order. Open' (MOS100).
  2. Select related option 15 in 'WO Individual Item. Open' (MOS115).
  3. Create a list of serial numbers for this WO. Use Add or Delete as all fields are key fields (ignore the position field).
  4. Return to (MOS100).
  5. Report materials and operations as usual. If some serial numbers cannot be completed, report a lower quantity when closing the operation.
  6. Open 'Work Order. Close' (MOS050) with related option 14 in (MOS100).
  7. Since this WO contains several serial numbers, use function F19='Cls Multi S/N'.
  8. In 'Work Order. Close' (MOS053), specify the warehouse, location, and a 'Scrap' location if any serial numbers need scrapping.
  9. If the serial number list is incorrect, use F15 to go to (MOS115) and make necessary Delete or Add adjustments.
  10. When everything is correct, use F14='Close Work Order' to complete the WO closure.
  11. If 'Scrap' is selected on any line, proceed to 'Serial Number. Scrap' (MOS890) for scrapping or scrapping proposal.
  12. If the WO needs reopening to report more material or operation time, reopen in 'Work Order. Close' (MOS050) and WO Operation. Report (MOS070) with the full WO quantity using a negative quantity (ensures adjusted cost sharing).
    Note: For urgent quantity needs, split the WO before closing using option 55='Split WO' from (MOS100) to 'Work Order. Split' (MOS055). Use the 'Create' option to define the quantity to remain on the original WO; the rest is put on a new WO for separate handling and closure.
