Material Requirements Planning (MRP) Glossary

 

Expand/Collapse all Show/Hide All

Expand/Collapse item  Action By Date

Date by which action should take place, based on the recommendation in the action field.

 

Expand/Collapse item  Assembly

A group of components or parts which are combined to form a major subdivision of the finished product. An assembly can be a finished good or a component of a higher-level assembly.

 

Expand/Collapse item  Back Flush

The deduction from inventory of a component used in an assembly by exploding the bill by the production count of assemblies produced. Backflush issues inventory items when completion transactions are updated.

 

Expand/Collapse item  Blow Through

To explode a bill's phantom assemblies into their components. For more information, see Phantom Bill.

 

Expand/Collapse item  Build Time

The time needed to make (manufacture) an item from work orders. In a multi-level bill of materials, this includes the time between levels. MRP replaces this value for any bill in which the vendor lead time is non-zero, as specified from the inventory file for the item. If the vendor lead time in inventory is zero, the default lead time is used. In the case of a make item, this corresponds to the build time.

 

Expand/Collapse item  Component

Any raw material, part, or sub-assembly listed in the line entry section of a bill. All bills contain one or more components.

 

Expand/Collapse item  Demand

The amount of an inventory item needed to complete a sales order or a projected demand. Also includes a component in an assembly. This information comes directly from the sales order, projected demand, or work order.

 

Expand/Collapse item  Effective Date (ECO)

The date on which a component is to be added or removed from a bill. This date is used to activate engineering change orders.

 

Expand/Collapse item  Engineering Bills

Engineering bills are ignored by MRP Generation.

 

Expand/Collapse item  Engineering Change Notice

The document issued by an engineering department to advise all concerned parties (for example, purchasing, planning, or manufacturing) that a change has been, or will be, made to an assembly.

 

Expand/Collapse item  Exploded

An item group that comprises a sales kit can be exploded or broken down into its individual component items (every individual component is listed separately).

 

Expand/Collapse item  Firm Planned Work Order

A work order which has not been released to the shop. Firm planned work orders cannot have transactions posted against them.

 

Expand/Collapse item  Group

Group code for a warehouse. This allows MRP Generation to consolidate recommendations for specified warehouse groups. A separate MRP Report is printed for each group.

 

Expand/Collapse item  Indented Bill of Materials (BOM)

A format which lists all component items on a bill, with each level indented from the preceding level. If a component is used in more than one parent within a given bill structure, the component will appear under each bill in which it is used. The indented report format provides a complete view of the bill structure.

 

Expand/Collapse item  Indented Where-Used

A listing of all bills which directly or indirectly require a selected component.

 

Expand/Collapse item  Issued/Supplied

The quantity supplied from inventory (released work order), or supplied by a linked work order (either firm-planned or released). If the released work order quantity is less than the demand, the balance comes from inventory; if it is more, the balance goes into inventory.

 

Expand/Collapse item  Kit Bill

A single-level bill used to define a group of items commonly sold as a single unit. Kit bills can contain comment lines, but not miscellaneous charges. This is the only bill type that can be used in the Sales Order module. Kit bill numbers must be inventory item numbers. Kit bills can either be assembled during the order picking process, or they can be assembled during the manufacturing process. In the latter case, Sales Order allows kits to be sold from stock.

 

Expand/Collapse item  Lead Time

The time needed to get an item from a supplier, pulled from the Std. Lead Time field for the primary vendor listed in the Inventory file for an item.

 

Expand/Collapse item  On-Hand

Actual quantity of inventory item on hand. On the MRP Report, the on-hand for an item is the sum of all warehouses in the current group.

 

Expand/Collapse item  On-Hand + PO

Sum of the quantities of an item in stock and on purchase order.

 

Expand/Collapse item  Option Bill

A bill which defines the components which comprise a specific option for a base bill. MRP supports bill options only if the top level of an existing work order has options.

 

Expand/Collapse item  Parent

A bill, level, or item to which other components are subordinate. This term is used in relation to a specific component.

 

Expand/Collapse item  Phantom Bill

A type of bill used primarily for transient (non-stocked) assemblies. When listing a bill containing components that are phantom bills, it is customary to blow through the phantom bill to show its component items. Phantom bills will be included in the MRP Generation process if the Integrate with Bill of Materials and the Include Phantom Bills check boxes are selected in MRP Options.

 

Using phantom bills reduces the number of components that must be specified for a bill while allowing the phantom assembly's components of kit bills or other phantom bills.

 

Because the phantom bill is not stocked in inventory, it is not assigned an inventory item number. Most reports that detail bill components allow the phantom bill itself to be suppressed while its individual components are detailed. This process is referred to as phantom blow-through.

 

Expand/Collapse item  Projected On-Hand

This is the projected quantity of an inventory item on hand on the date specified after completion of the transaction.

 

Expand/Collapse item  Reorder Point

Minimum available quantity at which the item needs reordering. The reorder point value printed is derived from the item's default warehouse.

 

Expand/Collapse item  Reorder Quantity

Recommended reorder quantity for the item. The reorder quantity value printed is derived from the item's default warehouse.

 

Expand/Collapse item  Required Date

The date an item needs to be completed and received to meet the shipping date of the sales order.

 

Expand/Collapse item  Revision Level

The change level of an item. A modification to an item which does not change the form, fit, or function of a product is normally controlled by a revision level.

 

Expand/Collapse item  Single-Level Bill

A bill which displays the components that are directly used in the manufacture of an item. If these components are themselves assemblies, that information will not appear on the single-level bill.

 

Expand/Collapse item  Standard Bill

A bill which lists all components required to produce a single parent item or finished product. Standard bills represent actual finished products or assemblies. The bill number of a standard bill must represent an inventory item number.

 

Expand/Collapse item  Suggested Order/Make Quantity

The quantity to be supplied by placing purchase orders or work orders.

 

Expand/Collapse item  Supplied From

On the MRP Report, the supplied from consists of work orders, purchase orders, and inventory issues. If the supplied value consists of multiple transactions, the word "various" appears on the report.

 

Expand/Collapse item  Supply

Amount of an item in inventory, plus the amount supplied by a purchase order or work order.

 

Expand/Collapse item  Unit of Measure (UM)

The standard unit of measure for inventory.

 

Expand/Collapse item  U/M Conversion

This program is used to define the relationships between various units of measure, which can then be used to automatically enter equivalent units of measure.

 

Expand/Collapse item  Where-Used

A listing of every parent item containing a given component and the respective quantity required from a specific bill.
