Overview
-
The Material Requirements Planning function generates planned (Status 1) Work Orders.
-
Material Requirements Planning planned Work Orders are the planned manufacturing supply orders to meet demand.
-
A Material Requirements Planning planned Work Order is a Work Order to make an item.
-
The Due Date of the Work Order is the date the item being manufactured is required in inventory.
-
The dates on the date tab for a Material Requirements Planning generated Work Order are calculated backward from the Due Date using the lead times on the Inventory Commodity Code or from the inventory item Master overrides.
-
Review and action by a planner is required to change the Material Requirements Planning planned Work Order status from Status 1.
-
The action called “Firming” a Work Order changes the Status to 2.
NOTE This is a separate step done by the Responsible Planner.
NOTE Upon firming the lot-controlled Work Orders, the 'Lot Number' field on the Work Order is updated based on the 'Manufactured Lot Auto Number Method' field on Division Master.
-
If the 'Manufactured Lot Auto Number Method' field is set to 'Use Work Order Number' then the 'Lot Number' field on the Work Order is updated with Work Order Number.
-
If the 'Manufactured Lot Auto Number Method' field is set to 'Use Next in Sequence (with Prefix)' then the 'Lot Number' field on the Work Order is updated with the number which is next in the sequence along with the prefix given in the 'Manufactured Lot Auto Number Prefix' field on Division Master.

Processing
Material Requirements Planning Planned Work Orders have a Status of 1, Planned.
The following tabs and fields are discussed as they pertain to Material Requirements Planning generated Work Orders.
Dates Tab
The values calculated by Material Requirements Planning are displayed in these fields.
Status Date: This date is updated by the system each time the Work Order Status is changed.
Scheduled Firm Date: This is the date on which the Material Requirements Planning generated Work Order is to be firmed. This date is calculated by taking the Due Date backed off by the Manufacturing Lead Time to determine the Start Date, which is then backed off by the Work Order Pick Lead Time and the Work Order Firm Lead Time.
Scheduled Release Date: This is the date on which this Work Order is to be released. This date is calculated by taking the Due Date backed off by the Manufacturing Lead Time to determine the Start Date, which is then backed off by the Work Order Release Lead Time.
Scheduled Pick Date: This is the date that the components are scheduled to be picked from the stockroom. It is calculated by the Due Date being backed off by the Manufacturing Lead Time and then backed off by the Work Order Pick Lead Time.
Effectivity Tab
Effective Date: This date is based on the date the Work Order is scheduled to be picked. It is used to determine which components will be extracted from the Bill of Material.
Misc Tab
The account default information is either sourced from the Inventory Item Accounts record if there are overrides or from the inventory Commodity Code assigned to the item.
WIP Account: Identifies the Work in Progress Account to which all charges applied to this Work Order will be charged. This field defaults from the Commodity Code associated with the Work Order Parent Item and can be overwritten on the Work Order with another appropriate Manufacturing Account.
Variance Account: Identifies the Variance Account to which the Work Order variances will be charged. This field defaults from the Commodity Code associated with the Work Order Parent Item and can be overwritten on the Work Order.
