Bill of Material (tibom1110m000)Use this session to define a bill of material (BOM) for manufactured items, purchased items or tools. Performance aspects The settings in this session could affect system performance and database growth. For more information, refer to the following topics:
. Main Item BOM Qty The number of manufactured items to which a bill of materials
(BOM) applies. The BOM quantity enables you to specify very small item
quantities as BOM components. Example You need very small amounts of certain colors to mix one liter of a specific paint, Cotton White. Therefore, a BOM quantity of 1000 liter is defined. The component quantities for the paint can then be as follows:
You must determine the BOM quantity in the Items - Production (tiipd0101m000) session. The BOM quantity enables you to specify very small item quantities as bill of material components. You might want to do this, for example, if you are creating a bill of material for a chemical dilution. Example You want to make a millionth part salt dilution. If the dilution's inventory unit is liters, you can specify a BOM for one liter, and a component item of one milligram of salt. However, one milligram could be too small to be measured accurately. It is more practical to specify a bill of material for a BOM quantity of 1000 liters, so the component item will be one gram of salt. BOM Qty The unit in which the inventory is defined, for example,
grams or meters. Position The component's position number. By default, LN shows the last position number used, plus 10. This procedure provides the sequence 10, 20, 30, and so on. The numbering of positions is unrestricted. For best results, you must use the default values so you can use intermediate numbers to insert components. The maximum position number of a component item is 9999. Sequence Number The BOM sequence number is a subdivision of the component item's BOM position number.
Item The component item that is part of the manufactured
item. The components must be items of the Purchased item type or the Manufactured item type. The component must be defined in the Items (tcibd0501m000) session. Note If the main item is of the item type Tool, components with the Tool type are allowed. For more information on procuring purchased configurable items, refer to: Engineering Item Revision A version or revised version of an engineering item (E-item) or
a revision-controlled item, that is, an item linked to an E-item. Several
revisions of an E-item can exist. Example E-item: Mountain bike E-MB01
General Effective Change Order The change order that defines the effective date of the BOM line. Expiry Change Order The change order that defines the expiry date of the BOM line. First Allowed Order Date The value of the First Allowed Order Date field in the Items - Ordering (tcibd2100m000) session. Last Allowed Order Date The value of the Last allowed Order Date field in the Items - Ordering (tcibd2100m000) session. Net Quantity The amount of a component item used in the manufactured item. To calculate this amount, multiply the number of units by the value in the Length field and the value in the Width field. For example, if you specify ten units of a component that is 2 cm long and 3 cm wide, the net quantity is 60 (10*2*3). If the width is not specified, the net quantity is 20. Note If a negative quantity is shown, the production of a manufactured item results in a by-product. This by-product is entered in the bill of material with a negative quantity, which is used to calculate the gross material requirement. Quantity-independent lines If the BOM lines are quantity independent, a zero is displayed in this field. Scrap Percentage Recording 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 will also be copied. However, these values will only be 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 will not be copied. In this case, the scrap quantity and scrap factor will be zero (0). 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 will be lost during production. The quantity is a fixed quantity that is independent to 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 will also be copied. However, these values will only be copied if the sequence number is the only thing changed, for example, wheel 10/1 to wheel 10/2. If a new item exist on the BOM line, for example, wheel to spare wheel, the scrap data will not be copied, In this case scrap quantity and scrap factor will be 0. Length 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 and multiplied by the Width field, if applicable. In the Print Production Order Documents (tisfc0408m000) session, you can only print a sawing list if you have entered the Length field for the given component. If you have entered both the Length field and the Width field, you can print a cutting list. Width This field can be used, together with the Length field and
number of units, to calculate the net quantity. The net quantity is the Length field multiplied by the number of units and multiplied by the Width field, if applicable. If you have entered both the Length field and the Width field, you can print a cutting list in the Print Production Order Documents (tisfc0408m000) session. Size Unit The unit of measurement used. Number of Units The number of times that the required quantity of the
material, specified in the Length field and/or the Width field, appears in the product. Operation The operation for which
operation the material of the BOM line is issued to the job shop.
Note To avoid entering the code of a nonexistent operation, you are advised use the zoom function for this field and select an operation from the Routing Operations (tirou1102m000) session. Performance aspects The setting of this field could affect system performance and database growth. For more information, refer to Material for multiple operations. Material-Routing Relations If this check box is selected, material-routing
relationships are present for the BOM component. Warehouse The warehouse where the component is stored and where the
allocation for a production order is made. Note If the component is a phantom, and you select the Inherit Warehouse if Parent Item is a Phantom check box, LN allocates the requirement for the component in the warehouse of the component's parent item. 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. Phantom If the component item is defined as a phantom in the Items - Production (tiipd0101m000) session, LN will select this check box. You can override
that value here. Note
Performance aspects The setting of this field could affect system performance and database growth. For more information, refer to Phantoms. 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 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 stock is always ignored during planning. Inherit Warehouse if Parent Item is a Phantom Determines on which warehouse LN allocates the requirements for this
component and from which warehouse LN issues the component if the component is a phantom. If this check box is cleared, LN plans the material issue on the warehouse of the phantom item, regardless of whether the item is a phantom item or not. You define this warehouse in the Warehouse field in the Bill of Material (tibom1110m000) session. If this check box is selected, and this component is a phantom item, LN plans the material issue on the warehouse of the parent item of the phantom item. Alternatives Present If this check box is selected, one or more alternative materials are present in the Use Up and Alternative Materials (tibom0150m000) session. Note
Use Up Materials Present If this check box is selected, a use-up material is present in the Use Up and Alternative Materials (tibom0150m000) session. You cannot modify the setting of this check box. To view or maintain use-up materials, on the appropriate menu, click Use Up and Alternative Materials. Allow Multiple Items If this check box is selected, LN can distribute the net quantity of the material over multiple items. For
example, the net quantity can be divided over the use-up material and the standard material or over the
standard material and one or more alternative materials. If this check box is cleared, LN issues only a single
item for this BOM line for one production order. For examples, refer to To distribute a material requirement over multiple materials. Inherit Demand Peg If a production order is transferred from Enterprise Planning to Job Shop Control, the
order can have a demand peg. Note A specification is generated for the peg. You can use this field to determine whether the material must have this demand peg as well. Miscellaneous Order Lead Time The production time of an item expressed in hours or days,
based on the lead time elements as defined in the routing operations. You can determine the order lead time by clicking Update Order Lead Time in the Items - Production (tiipd0101m000) details session. Specify Material Offset If this check box is selected, you can specify the lead-time offset. Lead Time Offset The lead-time offset. LN uses the lead-time
offset in capable-to-promise calculations. The date that a
component must be available is calculated by subtracting the lead-time offset
from the requirement date of the end item. Note You can only type the lead-time offset if the Specify Material Offset check box is selected. Material Offset Select Hours or Days as the
time unit in which you want to express the lead-time offset. Actual Material Offset If the Specify Material Offset check box is selected, the
actual offset is equal to the number of hours or days specified in the material
offset field. If the Specify Material Offset check box is cleared, the
actual offset is equal to the Order Lead Time. Order Yield The yield that is used in calculations for aggregate
planning. When LN plans material requirements by using a fixed lead time, LN uses the Order Yield field, rather than routing data. This process is carried out in the Order Planning module. The value that you type in this field must be an estimation of the yield for all operations in the item routing. For example:
In this case, the value that you must type in the Order Yield field is .90 * .80 * .90 = 65% Default value 100 Setup Scrap The scrap that is used in calculations for aggregate
planning. When LN plans material requirements by using a fixed lead time, LN uses the Setup Scrap field, rather than routing data. The planning process is carried out in the Order Planning module. The value that you type in this field must be an estimation of the scrap for all operations in the item routing. Default value 0 Customer Furnished Material If this check box is selected, the material is a customer furnished material. Note Only visible when the Customer Furnished Materials parameter are selected in the Implemented Software Components (tccom0100s000) session. Contains Customer Furnished Material If this check box is selected, the end-item is an item that is built using
one or more customer furnished material. Exceptions Present If this check box is selected, this BOM line has exceptions linked to it. Exceptions are part of the unit effectivity concept. Standard Configuration If this check box is selected, the BOM line is part of
an item’s standard configuration. The costs for the BOM line are included in
the standard cost. If the Standard Configuration check box is cleared, the BOM
line is not part of an item’s standard configuration. The costs for the BOM
line are not included in the standard cost. The Standard Configuration check box in combination with the setting of the Valid check box in the Exceptions (tcuef0105m000) session indicates whether an BOM line is used for a specific effectivity unit.
Note If the BOM line has exceptions attached, but you do not want to use the exceptions, for example, for selling spare parts, or for an end item which is not unit-effective, then you can clear this check box. Supplied by 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, but it is supplied by the subcontractor. Therefore, the material's planning and costing is not taken into account. If this check box is cleared, and the material is linked to a subcontracted operation, the material is sent to the subcontractor. Text If this check box is selected, a text is present. 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. Link with EDM If this check box is selected, the engineering bill of
material line was copied to the production bill of material. Reference Designators Present If this check box is selected, one or more reference designators are present in the Reference Designators by BOM (tibom0120m000) session. You cannot modify this check box. To view or maintain reference designators, click Reference Designators by BOM. In Process by Change Management If this check box is selected, the BOM line is under
change management control. If a change order is linked to the BOM, and the
change order has not yet been approved, LN selects this check
box. In the Change Management (CHM) module you can keep track of the effective and expiry dates of a BOM line according to a defined procedure. Extra Information If extra information exists about the BOM line, you can find
the information in this field. Revision If the item has a relationship with the engineering item, LN uses this field to
display the revision of that engineering item.
Level Up Displays the one level structure high for the selected BOM
line. Level Down Displays the one level structure down for the selected BOM
line. Show All Lines Displays all the BOM lines. Show Effective Lines Displays the BOM lines that are effective and not
expired. Multilevel View Start the View tree structure and maintain the multi-level BOM in the
GBF browser. Material-Routing Relationships Checks whether material-routing relations are present for the
BOM line.
