Tip
When a routing or
BOM code is blank,
it defaults to the
item number value.
Modifying Work Orders
Every work order has a BOM and a routing code, which determine the
order’s product structure and routing. You can specify these for each daily
scheduled requirement. Modify these codes as needed in Work Order
Maintenance (16.1) and then re-explode the order.
Re-explode Planned, Firm Planned, or Batch orders as needed by running
MRP or by changing the work order status to Exploded, Allocated, or
Released.
Modifying Work Order Bills
Often you must modify the bill of a rework order by adding components.
Sometimes, as well, you must modify the bill of a regular work order. For
example, there may be an engineering change order needing immediate
implementation for all work-in-process, including orders that have been
exploded, allocated, or released.
How you make a replace an existing component with a new one depends
on the work order status.
• If an order has been released, you can issue the new component and
return the old one. This results in an unfavorable material usage
variance for the new component and a favorable usage variance for
the old one. Use Work Order Bill Maintenance (16.13.1) to add the
new component to the work order before issuing it.
• If an order is allocated or exploded, use Work Order Bill Maintenance
to add the new component, updating the quantity required and
quantity allocated, and delete the old one.
After modifying a work order bill, you should not change the status back
to Firm Planned, since that causes the standard bill to be re-exploded.
