Replan or Refresh Production Orders Directly

The Replan function on production orders is typically used after you have added or changed components that constitute underlying production orders. The function calculates changes made to components and routings lines, and it includes items on lower production BOM levels for which it may generate new production orders.

Based on the changes you have made to the components and routing lines, the Replan function calculates and plans for any new demand for the production order.

The Refresh function on production orders is typically used after you have done one of the following:

• Created a production order header manually to calculate and create line data for the first time.
• Made changes to the production order header to recalculate all the line data.

The Refresh function calculates changes made to a production order header and does not involve production BOM levels. The function calculates and initiates the values of the component lines and routing lines based on the master data defined in the assigned production BOM and routing, according to the order quantity and due date on the production order’s header.

You can either insert the production order lines manually or use the function that calculates the production order lines from the header.

Note

Note:
If you use the Refresh function to recalculate production order lines, the old production order lines are deleted and new lines are calculated.

To replan a production order

1. Choose the icon, enter Firm Planned Prod. Orders, and then choose the related link.

2. Open the production order you want to replan.

3. On the Lines FastTab, choose the Lines action, and then choose the Components action.

4. Add a component, which is a produced item or subassembly.

5. From the production order, choose the Replan action.

   On the Replan Production Order page, proceed to define how and what to replan.

6. In the Scheduling Direction field, select one of the following options.

   Option	Description
   Back	Calculates the operation sequence backwards from the earliest possible ending date, defined by due date and/or other scheduled orders, to the latest possible starting date. Note: This default option is relevant in the majority of situations.
   Forward	Calculates the operation sequence forward from the earliest latest possible starting date, defined by due date and/or other scheduled orders, to the earliest possible ending date. Note: This option is only relevant for expedite orders.

7. In the Plan field, select whether to calculate production requirements for produced items on the production BOM, as follows.

   Option	Description
   No Levels	Do not consider lower level production. This only updates the item’s schedule, like refresh.
   One Level	Plan for first-level production demand. First-level production orders may be created.
   All Levels	Plan for all-level production demand. All-level production orders may be created.

8. Select One Level, and choose the OK button to replan the production order, and calculate and create a new underlying production order for the introduced subassembly, if it is not fully available.

Note

Note:
Changes implemented with the Replan function are very likely to change the capacity need of the production order and you may therefore have to reschedule operations afterwards.

To refresh a production order

If you have amended production order lines, components, or routing lines, you must also refresh the information on the production order. In the following procedure, the components are calculated for a firm planned production order. The steps are similar for routing lines.

1. Choose the icon, enter Firm Planned Prod. Order, and then choose the related link.

2. Choose the New action. For more information, see Create Production orders.

3. Choose the Refresh action.

4. On the Refresh Production Order page, select one of the following options:

   Field	Option	Description
   Scheduling Direction	Forward	Scheduling starts from the starting date and proceeds forward to the finishing date. You must fill in the starting date to use this option.
   	Backward	Scheduling starts from the ending date and proceeds backward to the starting date.
   Calculate	Lines	Select this field to calculate the production order lines.
   	Routings	This field has no influence on calculating the production lines.
   	Component Need	This field has no influence on calculating the production lines.
   Warehouse	Create Inbound Request	This field has no influence on calculating the production lines.

5. Choose the OK button to confirm your selection. Now the production order lines are calculated.

Note

Note:
Calculating production order components deletes previous changes in the components.
