Understand work order reassignment

In certain situations, it is necessary to reassign a work order to another line. This could happen when one line has equipment failure and the work order has to be moved to another line for immediate completion. Work orders can be reassigned even if some units have already been produced against the work order. When reassigning a work order, its ID and the item being produced cannot be changed. For how to reassign a work order, see Reassign a work order to another line.

Note: Only work orders created from a line can be reassigned. Work orders created from a process are not shown in MES Web Portal.

A work order can be reassigned to another line if its status is New, Ready, Suspended, or On Hold.

A running work order, which means it has at least one job running, cannot be reassigned to another line. The running work order must first be stopped by:

• Changing its status to Suspended or On Hold, or

• Stopping or completing any of its running jobs

Reassigning a work order to another line has the following results:

• All the existing jobs are deleted and new jobs are created according to the entity configuration of the new line. To ensure job record uniqueness, the sequence numbers for the new jobs will start with the sequence number that follows the highest sequence number used for any previously existing jobs in the work order.

• Any existing production data for the work order is retained.

• The starting quantity defaults to the quantity remaining. The quantity remaining is the difference between the original starting quantity and the total good quantity produced in any job for this work order that ran on the line's production entity, and any entities in parallel with the production entity, plus the reject quantities produced in these jobs or any jobs upstream from them.

• The required quantity defaults to the original required quantity less any good quantity or 0, whichever is greater. The quantity produced is the total of any good quantity produced in any job for this work order that ran on the line's production entity plus any entities in parallel with the production entity.

• The produced and rejected quantities show the totals for the reassigned work order when a different line is selected. These totals do not include production from lines to which the work order was previously assigned. Each time the work order is reassigned these totals are reset to 0, because the starting and required quantities are being updated to just the remaining amounts for the work order on its new line.

• The starting and required quantities are updated based on the production that has already been reported for the work order, to reflect just the amounts that need to be produced on the new line. Note that starting and required quantities are based on the production at the line's production entity. For example, say there are three entities in series in a line and a work order for 1,000 units. When the work order is suspended to be reassigned, 10 units were rejected at an entity upstream from the production entity, and the production entity for the line has processed 380 units. When the work order is reassigned to another line, the starting quantities for all three entities will be 610, regardless of how many units the other two entities had processed before the work order was suspended.

  Note: In some situations where scrap quantities have been reported, the calculations of starting quantity and required quantity will result in a starting quantity that is less than the required quantity, which is not permitted. These jobs cannot be reassigned to another job until either the job is updated through methods outside MES Web Portal or the job is completed.
