MRP Preferences

The number of days that are acceptable for items to be supplied before the date requested by a customer.

If the items in the order can be supplied earlier than the requested date minus the Days Before value, the system generates the Defer exception message. The larger the value in this box, the fewer exception messages are generated. If 0 is specified, then a message is generated whenever a supply date does not cover the demand.

This value in this box must be less than or equal to the value in the Grace Period box in the General section of this form. By default, 10 is specified in this box.

The number of days that are acceptable for items to be supplied after the date requested by a customer.

If the items in the order will be supplied later than the requested date plus the Days After value, the system generates an Expedite exception message. The larger the value in this box, the fewer exception messages are generated. If 0 is specified, then a message is generated whenever a supply date does not cover the demand.

This value in this box must be less than or equal to the value in the Grace Period box in the General section of this form. By default, 10 is specified in this box. This value is more critical than the Days Before value because a late delivery from a supplier impacts your ability to manufacture and ship to customers. We recommend that you use a value of 2 to 5 days.

The number of days within which the system excludes forecast records from demand data; the period starts from the day when MRP is performed. Forecasts are ignored by MRP if they have a start date specified on the Forecast (AM202000) form that is earlier than the MRP run date minus the number of days specified in this box.

By default, 30 is specified in this box.

The numbering sequence to be used to assign reference numbers to the forecasts that are created on the Forecast form.

The number of days within which MPS orders will be excluded from data used for MRP; the period starts from the day when MRP is performed.

The system inserts a default value of 30 in this box.

The default MPS type. The system uses the selected type to provide default settings for master production schedule orders created on the Master Production Schedule (AM201000) form.

The production order type that the system uses as the default order type for new planning orders generated during MRP. A type is available for selection only if the Planning function is specified for it on the Production Order Types (AM201100) form.

The number of days after the requested date of an item in a demand order within which the item can be received in inventory (purchased from a vendor or produced internally) and still be considered as satisfying the requested date.

During planning, for each demand date (that is, the requested date of an item in a sales order), the system determines if a supply order (that is, a purchase or production order) within the grace period can fully satisfy the demand.

The approach the system uses to trigger the replenishment of an item in a demand order during MRP. This setting is used if replenishment settings are specified for the item in the Planning Settings section of the Manufacturing tab of either the Item Warehouse Details (IN204500) form if warehouse-specific replenishment settings have been specified for the item or the Stock Items (IN202500) form if the item has no warehouse-specific settings.

You can select one of the following options:

• Safety Stock (default): The system uses the value specified in the Safety Stock box. We recommend that you select this option. You must select this option if you use forecasts.
• Reorder Point: The system uses the value specified in the Reorder Point box. You can select this option when stock items are stored in advance of sales orders and a forecast is not used.

The work calendar the system uses when calculating the action date for planned purchase orders. If the Use Fixed Manufacturing Times check box is selected, the system also uses this calendar when calculating an action date for planned production orders.

A check box that indicates (if selected) that the system considers sales orders on hold during MRP. If the check box is cleared, the system generates an exception message of the Order on Hold type for these orders on the MRP Exceptions (AM403000) form.

By default, the check box is cleared.

A check box that indicates (if selected) that the system considers purchase orders on hold during MRP. If the check box is cleared, the system generates an exception message of the Order on Hold type for these orders on the MRP Exceptionsform.

By default, the check box is cleared.

A check box that indicates (if selected) that the system considers production orders on hold during MRP. If the check box is cleared, the system generates an exception message of the Order on Hold type for these orders on the MRP Exceptions form.

By default, the check box is cleared.

A check box that indicates (if selected) that to calculate action dates for planned orders during MRP, the system uses the value of the MFG Lead Time box on the Manufacturing tab of the Item Warehouse Details form or the Stock Items form (depending whether warehouse-specific settings have been specified for an item). When the check box is cleared, the system dynamically calculates action dates for planned orders based on the item quantity and operation lead times specified in production orders.

By default, the check box is cleared.

A check box that indicates (if selected) that blanket sales orders that have expired are included in MRP. If the check box is cleared, the system ignores these blanket sales orders during MRP.

By default, the check box is cleared.
