Add a Component to a Bill of Material

When you click Component in the Bill of Material Maintenance (MPS) program, you can add or change, copy, or delete a component, and merge components from another bill of material. See Background and Road Map for more information.

Click Add if components exist. The parent item number, description, current ECL, ECL you are maintaining, and stocking unit of measure are displayed for information.
Enter or change data in these fields:

Field Name	Type / Max Length	Action / Description
Comp item no	Required 24 alphanumeric	Enter the item number of a component or click the Lookup icon and use the standard lookup options to select the component from a list. Its description and item status are displayed to the right of the item number. Note The component's status is highlighted* if it is not active (i.e., Item status in IM) is not 0. * displayed in the color associated with the bold attribute
Part designator	Optional 8 alphanumeric	Enter the identifier your company uses if this component is to be listed on this bill of material more than once. You may call this designator a balloon number, bubble number, file number, material tag, or reference number.
Qty per assy	Required 12 numeric in the format 9999999.99999	Enter the quantity of this component (in its stocking unit of measure) required to build one parent. For example, if the parent is a table and the component is a leg, you would enter 4. You can enter .00000 for a component whose usage is insignificant. When a manufacturing order is created, the any fractional requirement is rounded to the next integer. For example, if you use paint and the stocking unit of measure is gallon, a usage of .01000 and a manufacturing order quantity of 10 will result in a paint requirement of 1 gallon. Consider using a smaller unit of measure (e.g., ounces in this example) for better reflection of the actual requirement. For by-product items, enter a negative quantity per. For example, if you pick a large piece of sheet metal and cut off a small section, enter a negative quantity per under a different component number to return the remaining sheet to stock. A negative entry is not allowed on items with control numbers.
Reference code	Optional 4 alphanumeric	Enter a reference that your company uses. For example, you can use this field to associate this component with its balloon or bubble number on the engineering drawing. The Multi-Level BOM Listing (MPL) program can print components in sequence by this reference code rather than in item number order.
Flr stk cd	Required 1 alphanumeric	Accept the displayed code, select 0 to pick this component from on-hand inventory, or select 1 to backflush it from floor stock. The default code comes from the Flr stk cd field in the item's record in the Branch Item Maintenance (IMB) program. Items with control numbers cannot be assigned a floor stock code of 1.
LT offset	Optional 5 numeric in the format 999.99	Enter the number of shop days after the manufacturing order start date (due date minus lead time for the item) that this component is required. For example, an offset of 0 means the component is required at the manufacturing order start date; an offset of 3 indicates that the component is not required until 3 shop days after the manufacturing order start date. The offset cannot be greater than the lead time of the parent. Planning uses the lead-time offset to calculate delivery and due dates.
Setup matl loss	Optional 9 numeric in the format 9999.99999	Enter the quantity of material that you typically lose during the setup of an operation. For example, if the first two items produced after calibrating the machine do not meet quality standards, you would enter 2. Setup material loss is included in a cost rollup of a parent item: (Setup matl loss x Standard unit cost) / Standard lot size. Note If you do not have a routing established for the item, the cost rollup assumes a standard lot size of one.
Scrap %	Optional 5 numeric in the format 999.99	Enter the percent of this component that you normally scrap during manufacturing. The system increases the quantity required by this scrap factor: (Quantity ordered x Qty per assy) + (Quantity ordered x Qty per assy x Scrap % x 0.01) rounded up to the nearest integer. If your scrap factor is 5%, enter 5.00. The Manufacturing Order Maintenance (MIM) and Shop Paper Print (MSP) programs add the results of this calculation to the quantity required. Scrap is calculated for backflushed components based on the current scrap percentage when an operation sequence is completed.
Effective date	Required 10 date	Select the date when this component will be used for manufacturing orders, enter a date shortcut, or leave blank to use 01/01/1900.
Expiration date	Required 10 date	Select the date through which this component will be used for manufacturing orders, enter a date shortcut, or leave blank to use 12/31/9999.
Date revised	Optional 10 date	Accept the displayed login date, select another date, or enter a date shortcut when you revised this BOM.
Component type	Optional 3 alphanumeric	Enter the component type your company uses. This field is not used by the system, but you can use it in the custom reports.
Operation seq no	Conditional 4 alphanumeric	If you want to backflush picking, enter the operation sequence number when you want the system to pick this component. For example, if this component is not required until the third operation, enter that sequence number. If you selected the Backflush comps not attached to oper? option for your manufacturing branch in the System Options Maintenance (XM) program (Manufacturing Options), leave blank to pick this component when you enter pieces completed for the first operation. You can enter pieces completed in either the WIP Movement (WIPM) or Labor Entry (LLE) programs or import them with the Labor Import (LEI) program.
Comp reference	Optional 30 alphanumeric	Enter the reference your company uses. Note This field may have a different label based on the Component reference user label option for your manufacturing branch in System Options Maintenance (XM) program (Manufacturing Options).
Picking warehouse	Optional 2 alphnumeric	Select the warehouse location from which the component is backflushed.
Picking bin location	Optional 8 alphnumeric	Select the bin location from which the component is backflushed.
Replacement item?	Optional	Select if you replace this component under warranty or leave blank if you do not.
Critical item?	Optional	Select if this component is critical to this BOM or leave blank if it is not. If you select, the Manufacturing Order Picking Selection (MSS) program displays a C in the Pck? column when you have a shortage of this item.
Subs prohibited?	Optional	Select to prohibit the use of a substitute item for this component or leave blank to allow substitution.
Pick per receipt?	Optional	Select if you want backflushed components to be rounded based on the current receipt quantity or the total received for order. See Overview: Component Backflushing.
