MRP Options - Fields

(Integrate MRP with) Bill of Materials

Select this check box to integrate the MRP module with Bill of Materials. Clear this check box if you do not want to integrate the MRP module with Bill of Materials. This check box is available only if Bill of Materials is installed.

When these modules are integrated, MRP is supplied with a detailed database of components, assemblies, and subassemblies for calculating finished goods against raw materials. MRP disassembles all finished goods to the lowest levels to calculate the various items needed and provides the necessary material requirement information.

(Integrate MRP with) Work Order

Select this check box to integrate the MRP module with Work Order. Clear this check box if you do not want to integrate the MRP module with Work Order. This check box is available only if Work Order is installed.

When these modules are integrated, MRP automatically creates work orders using Auto Generate Work Orders. MRP analyzes supply based on open work orders, and ignores work orders created for special items.

(Integrate MRP with) Sales Order

Select this check box to integrate the MRP module with Sales Order. Clear this check box if you do not want to integrate the MRP module with Sales Order. This check box is available only if Sales Order is installed.

When these modules are integrated, MRP analyzes demand based on open sales orders as part of the information used for planning material acquisitions. Drop-ship sales order lines are ignored.

(Integrate MRP with) Purchase Order

Select this check box to integrate the MRP module with Purchase Order. Clear this check box if you do not want to integrate the MRP module with Purchase Order. This check box is available only if Purchase Order is installed.

When these modules are integrated, MRP analyzes supply based on open purchase orders as part of the information used for planning material acquisitions. Drop-ship purchase orders are ignored.

Restart MRP Generation on Error Condition

Select this check box to automatically restart the MRP Generation process if an error occurs. An error occurs because data has been deleted in the MAS database from another workstation during the MRP Generation process. Clear this check box to require a manual restart of the MRP Generation process.

Note Data entered or changed during the MRP Generation process is disregarded. It is recommended that all users exit the system during the MRP Generation process.

Explode Qty Change and Reschedule Recommendations

Select this check box to allow MRP Generation to explode demand requirements and reschedule recommendations on existing parent item work orders to lower level subassemblies and components, if MRP Generation recommends a QTY CHG or a RESCHED recommendation to a higher level subassembly. If you select this check box and a quantity change or reschedule is recommended to a firm-planned work order during the MRP Generation process, component dates and quantities are based on the new quantity or new required date of their parent item work order.

Clear this check box to allow component requirement dates and quantities to be based on the existing dates and quantities of their parent work order. This check box is available only if the MRP module is integrated with Work Order.

Base Effective Date on Demand Release Date

Select this check box to determine if the Effective Date is based on the demand’s projected release dates (for example, the Sales Order Promise Date) less the build time, or if the Effective Date is based on the Effective Date field in the MRP Generation window. If this check box is selected, the Effective Date field will not be displayed in MRP Generation. If this check box is cleared, the Effective Date entered in MRP Generation will be used to determine component requirements for all bills of material. For more information on effective dates, refer to the Bill of Materials Help system.

This check box is available only if the MRP module is integrated with Bill of Materials, and the Enable Engineering Change Control check box in the Bill of Materials Options window is selected.

Build Time Calc for Make Items

Select a method for calculating build times for make items. This allows MRP Generation to use the work order routing assigned to the work order or bill of material to determine the build time for items that use the procurement method of Make.

Select By Work Order to use the work order routing to determine the build time. If this option is selected, but the bill of material does not contain a work order routing, the item's lead time (from the primary vendor) will be used to calculate the build time. If no primary vendor is specified for the item or the item's lead time is zero, the Default Lead Time from MRP Generation will be used. This option can be selected only if the MRP module is integrated with Work Order. If the MRP module is not integrated with Work Order, the By Lead Time option is automatically selected.

Select By Lead Time to use the item's lead time (from the primary vendor). If no primary vendor is specified for the item or the lead time is zero, the default lead time from MRP Generation is used. If you use the By Lead Time option, the lead time specified for the items’ primary vendor, or the default lead time entered during the MRP Generation process, should be as close as possible to the actual build time when the MRP module is integrated with Work Order. This decreases the occurrence of reschedule recommendations that may be generated when the build time in the Work Order module varies from the specified lead time.

Note If the By Lead Time option is selected and MRP Auto Generate is used to create work orders, it is recommended that the item's default lead time be as close as possible to the actual build time of the item specified in the bill of material routing. Lead time does not exclude weekends, whereas routings are linked to work centers which contain work schedules. If MRP Generation is performed a second time and the actual build time for the work order is different than the lead time for the item, a Reschedule recommendation may be performed on the work order.

Round Integer U/M

Select this check box to round quantities of items whose standard unit of measure is defined as an integer unit of measure in Bill of Materials Options. If MRP is not integrated with Bill of Materials, the default integer unit of measure is Each.

Pull in Work Orders

Select this check box to pull the work order required date closer in to meet the demand. Clear this check box to keep the work order on the required date and issue "make" recommendations for demands preceding the work order completion date.

Push out Work Orders

Select this check box to push the work order required date further out to meet the demand. Clear this check box to keep the work order on the same date.

Include Phantom Bills

Select this check box to explode the components of the phantom bill onto the level of the bill where the phantom bill appears. For phantom bill components to be exploded on a work order during Auto Generate Work Orders update, this check box must be selected during MRP Generation, followed by the Auto Generate Work Orders update. Clear this check box if you want the system to ignore phantom bills and their components. This field is available only if the MRP module is integrated with Bill of Materials, and the Allow Phantom Bills check box is selected in the Bill of Materials Options window.

Include Overissues in On Hand

Select this check box to add the overissued quantity of the component back into the projected quantity on hand. Clear this check box if you regularly issue more components to a work order than are required; the overissued quantity will not be added back into the projected quantity on hand.
