SD-D  Material Requirements Defaults

This program sets default values for MRP parameters which are used when new items are created in IN-B  Enter Inventory.  Use MR-D  Enter MRP Parameters to globally or individually change the parameters associated with existing items.

Field Explanations

Include in MRP Generation?

If set to Y, whenever new items are created in IN-B  Enter Inventory, the Include in MRP Generation? switch will be set to Y, which means this inventory item will be included in the MR-F, Generate Material Requirements, program's calculations.  Almost always this default is set to Y.  Individual items can be excluded from the MRP Generation through MR-D  Enter MRP Parameters.

Expedite Buffer (Days)

This field controls the EXPEDITE message issued by the MRP program.  An EXPEDITE message is issued whenever enough material is on work order or purchase order, but is scheduled to arrive after it is actually needed.  The expedite buffer refers to the number of days within which an order can arrive and be considered late, as opposed to being Pegged to a later requirement.

Expedite Sensitivity (Days)

Most MRP dates are loosely planned, meaning that they are not so precise that an item arriving one or even a few days late actually needs attention.  You can reduce these unnecessary EXPEDITE messages through use of the Expedite Sensitivity setting.  Any requirement whose number of days late is equal to or less than the Expedite Sensitivity number of days will not receive an EXPEDITE message on any reports.

Delay Buffer (Days)

This field controls the DELAY message issued by the MRP program.  A DELAY message is issued whenever material on work order or purchase order is scheduled to arrive earlier than it is actually needed.  The delay buffer refers to the number of days beyond which an early arrival will get a DELAY message.

Delay Sensitivity (Days)

This field controls the printing of DELAY messages.  It should be set equal to the number of days an item can arrive early before it needs attention.  

Round MRP Quantities to the next whole number (Y/N)?

Certain items by their physical nature cannot be ordered fractional quantities.  For example, sheet steel may have to be ordered in complete sheets.  By setting this field to Y, the MRP program will always round the suggested order quantity to the next whole number.
