About Modifying a Work Order

You can perform the following tasks to modify a work order:
  • Change the work order plan: You can change the planned start and end dates and the priority of a work order.
  • Add an operation: You add an operation to the serials/lots for which the next operation is not ready. To add an operation:
    1. Create an operation.
    2. Assign a sequence number to the operation such that the number lies between the sequence numbers of the previous and next operations, and it is greater than the latest ready operation. If, however, you want to perform this operation at the same time as another operation, provide the same sequence number as that operation.

      All the serials/lots in the work order are added to the operation.

    3. If you do not want to the operation to be perform on a serial/lot, remove it from the operation.
  • Remove an operation: You can remove an operation if it is no longer required to complete the work order. However, you can remove the operation only if it is not ready.
  • Remove an operation for a serial/lot: You can remove an operation for a serial/lot if it is no longer required to complete the work order for that serial/lot. However, you can remove the operation only if the serial/lot is not ready for the operation.
  • Modify an operation: You can modify the details of an operation such as the name, description, behavior, and so on. You can modify an operation only if it is ready or not started. You can modify the sequence number of an operation only if the operation is not ready. And, the sequence number must be greater than or equal to the sequence number of the latest in-progress operation in the work order.
  • Replace an operation: You can replace an operation with a new one by removing serials/lots from the operation and adding them to the new operation. You can, however, replace an operation only for serials/lots for which the operation is not started.
  • Change BOM assignments of an operation: You can change the BOM assignment of an operation only if the operation is not started.
  • Add a property group or change a property value: You can add a property group or change the value of a property in an operation only if the operation is not yet started.
  • Change the documents attached to an operation: You can upload a document to the document store, or attach or remove a document from an operation that is not started.

Replacing an operation

Suppose a work order has the following operations:
  • Turning
  • Drilling
  • Assembling
  • Painting
  • Testing
  • Packaging
For two of the lots, you want to perform endurance testing instead of the normal testing operation. In that case, before the testing operation is started on the two lots:
  1. Create the endurance testing operation such that the sequence number is the less than or equal to that of the testing operation (and greater than that of the painting operation), and save the changes to the work order. All the lots in the work order are added to the operation.
  2. Except for the two lots on which you want to perform endurance testing, remove all the lots from the endurance testing operation.
  3. Remove the two lots from the testing operation.
