| # Engineering BOM (tiedm1110m000) An EBOM is a bill of material for an engineering item revision. Use this session to display and edit the component parts of the EBOM. The components can be either E-items or production items, such as purchased items or manufactured items. Related topics Engineering BOMs Engineering items Unit effectivity in EDM Overview of reference designators Defining alternative materials Engineering Item The code for the engineering item (E-item) for which you want to define a bill of material (BOM). To enter a new E-item, click New or click Find a record. Note The following items can only be non-configurable items: Main item Sub item Related topics Engineering data management summary Engineering BOMs Structure of a single-level BOM Engineering items Integration Manufacturing and Document Management Defining alternative materials Description The name of the main (or parent) item. E-Item Revision The engineering item's revision for which you are defining a bill of material (BOM). E-Item Revision The parent or main revision of the E-item for which you are defining a bill of material (BOM). Note Each revision can have a separate EBOM. Status The status of the revision. BOM Quantity 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:
Paint Cotton White, 1000 liter:
White | 999 liter
Yellow | 0.6 liter
Red | 0.2 liter
Blue | 0.2 liter
Position Number The position number of the EBOM line. This is equivalent to the position number of a PBOM, except there is no sequence number. A sequence number defines items that are valid on different dates. Revisions can carry out that (of defining items that are valid on different dates) function for engineering items. Component Type The type of the component in the EBOM line. Component The component of the engineering item (E-item) revision. The component can be either an E-item or a standard item. Note You can enter a new component if you click New. You can modify an existing component if you double-click the component line. An EBOM is formed by listing the components of each item revision. The EBOM components can have their own BOM, where they are referred to as E-items. Component Revision If the component is an E-item, LN enters the revision of the E-item that you select which has the status In-design in this field. You can only maintain EBOMs for revisions with the status In-design. Standard Configuration If this check box is selected, the EBOM line is part of an item’s standard configuration. The costs for the EBOM line are included in the standard cost price. If the Standard Configuration check box is cleared, the EBOM line is not part of an item’s standard configuration. The costs for the EBOM line are not included in the standard cost price. The Standard Configuration check box in combination with the setting of the Valid check box in the Exceptions (tcuef0105m000) session indicates whether an EBOM line is used for a specific effectivity unit. If the Standard Configuration check box is selected, and the Valid check box is cleared for an exception linked to the EBOM line, the EBOM line will be omitted for a specific effectivity unit or requirement. If the Standard Configuration check box is cleared, and the Valid check box is selected for an exception linked to the EBOM line, the EBOM line will be added for a specific effectivity unit or requirement. Note If the EBOM 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. Related topics Overview of unit effectivity Exceptions Present If this check box is selected, a exception is attached to this EBOM line. You can see that exception by clicking Exceptions in the session. Related topics Unit effectivity in EDM. Overview of unit effectivity. Length The length of the component that is on the EBOM line. Note Length can also be used to calculate Net Quantity:
    			 Net Quantity =
    			 Length *
    			 Width *
    			 Number of Units.
Extra Information You can enter eight characters of text. If you want to enter more text, click Text Editor. Width The width of the component. Note Width can also be used to calculate Net Quantity:
    Net Quantity =
    			 Length *
    			 Width *
    			 Number of Units.
Text If this check box is selected, a text is present. Number of Units The number of times the component occurs in the EBOM. For a physical item, this is equal to the number of units that are in the length or area you have defined. Note Number of Units can also be used to calculate Net Quantity:
    Net Quantity = (Length * BOM
    			 Conversion Factor) * (Width * BOM
    			 Conversion Factor) *
    			 Number of Units /
    			 Conversion Factor
If the component has no Width, the value of ( Width * BOM Conversion Factor) is left out of the formula. You can define conversion factors in the Conversion Factors (tcibd0103m000) session. LN uses the conversion factor which is applicable to the units of the item or E-item. BOM Conversion Factor is the conversion factor from the base unit to the BOM quantity. This is derived from the BOM Unit of Measure. Net Quantity The quantity of a component or material that is theoretically required to make a certain quantity of a product. This quantity is referred to as the net quantity because in practice you may need more than this quantity to make up for certain losses of the material or the product. Note This value must be greater than zero. Quantity Independent If this check box is selected, the E-item's net quantity is copied to update the scrap quantity in the BOM. If this check box is cleared, the E-item's net quantity is copied to update the net quantity of the BOM. Reference Designators Present If this check box is selected, one or more reference designators are present in the Reference Designators by Engineering Bom (tiedm2110m000) session. You cannot modify this check box. To view or maintain reference designators, click Reference Designators by Engineering Bom. Related topics Overview of reference designators Alternatives Present If this check box is selected, one or more alternative materials are present in the Use Up and Alternative Materials by Engineering BOM (tiedm2115m000) session. You cannot modify this check box. To view or maintain alternative materials, click Use Up and Alternative Materials by Engineering BOM. Related topics Alternative materials in BOMs Defining alternative materials Use Up Materials Present If this check box is selected, a use-up material is present in the Use Up and Alternative Materials by Engineering BOM (tiedm2115m000) session. You cannot modify this check box. To view or maintain alternative materials, click Use Up and Alternative Materials by Engineering BOM. Related topics Using up remaining stock of outdated items 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.
