Generic BOMs (tipcf3110m000)

Use this session to define the generic BOM and all its components for a generic item or a purchased configurable item. An item is configurable when the Configurable check box is selected. You can select the Configurable check box in the Items - General (tcibd0501m000) session.

You can use a configurable purchased item in a BOM for a manufactured or generic assembly item.

A manufactured or generic assembly items can hold following components:

Note
  • For purchased configurable items, you can specify quantity greater than 1 on the BOM line.

  • The main configured end item can be manufactured or generic with the Default Supply Source as Assembly. The child item can be configurable purchase item.

  • The main item cannot be a configurable purchased item.

The selections of the customer can be used to generate BOMs. Constraints control the translation of customer requirements into the components of the BOMs for product variants.

You can enter a planning percentage for the components of the BOM. Planning percentages enable the user to create a forecast of the demand for the item.

Note

If the Multilevel PCF Choice Structure check box in the Product Configuration Parameters (tipcf0100m000) session is selected, you can use extra generic levels in the product structure for a multi-level selection structure.

 

Generic Item
The code of the configurable item.
Default Supply Source
The source that supplies an item by default. An item can be supplied by using purchase orders, production orders, assembly orders, or warehousing orders.

The default supply source determines what type of order is used to supply the item, but in general, you can override the default and specify an alternate source.

This field can be used to determine what type of supply order LN must create if you enter a sales order for this item and the item's inventory on hand is not sufficient.

If the item type is Manufactured or Generic, this field can be Shop Floor or Assembly.

If the item type is Engineering Module, this field is Assembly and cannot be changed.

If the item type is Purchased, this field is Purchase and cannot be changed.

BOM Quantity
Defines the number of manufactured items on which the item's BOM is based. It enables you to specify very small item quantities as bill of material components.
BOM Quantity
The inventory unit of the BOM unit.
Position
The position number of the component allows unequivocal recognition of the generic bill of material. This number is comparable to the position number in the production bill of material. In a generic BOM, however, several variants can be defined for each position number.
Position
The sequence number indicates that several versions of the component for each position number can exist.

For product variants, enter the sequence number within a position number of the generic bill of material. This sequence number can also be left empty.

Item
The item code of the component. Generic and standard items are allowed. A generic item can also be the main item in another generic bill of material. A standard item can also be a main item in a production bill of material.

The components must be items with the Purchased, Manufactured, or Generic item type. The component must be predefined in the Items - Production (tiipd0101m000) session. From this field, you can directly record items in the Items - General (tcibd0501m000) session.

Operation
Operations needed to produce a generic manufactured item are defined in the generic routing by means of operation numbers. These operations are included in the production order planning.
Warehouse
The warehouse where the component is stored and where the allocation for a production order is made.
WMS Controlled
If this check box is selected, you defined in the Warehouses (tcmcs0503m000) session that an integration with a Warehouse Management System (WMS) exists. The value of the Lot Selection field in this session must be the same as in the used WMS.
Lot Selection
This field is applicable for lot-controlled items. The values Any, Same, or Specific regard the special conditions for the delivery of lot items on order lines. The values also determine the way lot numbers are assigned.

Allowed values

Lot Selection

Assembly
Operation
The assembly operation to which the purchased configurable item is linked. This data is displayed only for configurable purchased child items.
Line Station
The line station to which the purchased configurable item is linked. This data is displayed only for configurable purchased child items.
Constraint
The code of the constraint that is applicable to this component.

In the constraint text, you can define the condition under which this component must be selected when you generate the project structure.

Length
The length of the component.

This field can be used, together with the Width field and number of units, to calculate the net quantity.

The net quantity is the Length field multiplied by the number of units, multiplied by the Width field if applicable.

Width
The width of the component.

This field can be used, together with the Width field and number of units, to calculate the net quantity.

The net quantity is the Length field multiplied by the number of units, multiplied by the Width field if applicable.

Number of Units
The number of units is the number of times that the component appears in the specified length (and width, if applicable).
Net Quantity
The net quantity of the component (excluding the scrap percentage) required to produce the manufactured item.
Net Quantity
The inventory unit of the net quantity.
Scrap Quantity
Unusable material or rejects of intermediate products, for example, because of faulty components, or products lost in cutting or sawing operations. The gross material requirements and/or an operation's input quantity must be increased to account for anticipated scrap.

In the BOM, you can define scrap as a percentage of the net material requirements, which is the scrap factor, and as a fixed quantity, which is the scrap quantity. A scrap quantity is mostly used to define the amount of material that is lost every time when you start producing, for example, to test the equipment.

For an operation, you can only define the scrap as a fixed quantity.

The quantity of material that is lost during production. The quantity is a fixed quantity that is independent of the quantity produced. Recording a scrap quantity prevents shortages in production.

Scrap is an extra loss in addition to the loss caused by the yield being less than 100%.

If you generate the BOM from an engineering BOM, the scrap factor and scrap quantity values are also copied. However, these values are only copied if the sequence number is the only thing changed, for example, wheel 10/1 to wheel 10/2. If a new item exists on the BOM line, for example, wheel to spare wheel, the scrap data is not copied. In this case, scrap quantity and scrap factor will be zero.

Scrap Factor
Defining a scrap factor prevents shortages in production. The scrap factor is expressed as a percentage loss.

A scrap factor of 5% means that LN will allocate 5% more of a component for a production order (gross material requirement).

Scrap is an extra loss in addition to the loss caused by the yield being less than 100%.

If you generate the BOM from an engineering BOM, the scrap factor and scrap quantity values are also copied. However, these values are only copied if the sequence number is the only thing changed, for example, wheel 10/1 to wheel 10/2. If there is a new item on the BOM line, for example, wheel to spare wheel, the scrap data is not copied. In this case, the scrap quantity and scrap factor will be zero.

Planning Quantity
The planning quantity of a component in a generic bill of material is used in the Enterprise Planning calculation when determining the average requirements for this component, as a result of planned orders for generic items on a higher level in the generic product structure.

The Enterprise Planning calculation will incorporate this planning quantity (multiplied by the planning percentage) as the net requirement for the production of the generic manufactured item. The exact material requirements are not known during the Enterprise Planning calculation, because there is no customer for the generic item in this planning phase. As a result, a specific product variant has not yet been selected.

Planning Percentage
The planning percentage serves to perform a Enterprise Planning calculation, as does the Planning Quantity field.
Percentage Required
The percentage of raw material required before the operation can be started.

Default value

The default is 0% and this field is unavailable. You can start the operation with no raw materials available (at least in theory).

Effective Date
The first date on which the relevant standard cost price takes effect.
Expiry Date
The expiry date indicates from which date the generic BOM is invalid.
Phantom
If the component is defined as a phantom in the Items - Production (tiipd0101m000) session, LN selects this check box. You can override the value in the current field.

You can use phantom items to record technical information about the product structure or to carry out cost price calculations.

Related topics

Use Phantom Inventory
If this check box is selected, LN checks if any phantom inventory is available.

If the phantom item is available in inventory, and the quantity is sufficient, this inventory is used as a component in the production order.

If no phantom inventory is available, or if the quantity is insufficient, the inventory is not used. LN treats the component as a normal phantom item, so the phantom is exploded for the total quantity.

Note

The phantom inventory is always ignored during planning.

Print on Order Document
If this check box is selected, the BOM component is printed on the order document.

Users can specify whether or not they want to print a BOM material on the order document. For example, a user can choose not to print the floor stock in the material list.

Text
If this check box is selected, a text is present.
Use Lead Time Offset
If this check box is selected, you can specify the lead-time offset. If you do not use lead-time offset, material must be present at the start of an operation.
[Dy]
The lead-time offset in days. The date that a component must be available is calculated by subtracting the lead-time offset from the operation's end date.
Note

You can only enter the lead-time offset if the Use Lead Time Offset check box is selected.

Extra Information
If extra information exists about the BOM line, you can find it in this field.
Supply to Subcontractor
If you subcontract one or more operations, or an item's entire production process, you can choose whether or not to send material to the subcontractor to use for the subcontracted item.

If this check box is selected, the material is not sent to the subcontractor. The material is supplied by the subcontractor.

If this check box is cleared, and the material is linked to a subcontracted operation, the material is sent to the subcontractor.
