The MBC number generated by LN using the number group
that you enter in the Number Group for MBC field in the Engineering Data Management Parameters (tiedm0100m000) session.
MBC Action (tiedm3120m000)Use this session to list the actions defined for a mass bill of material change (MBC).
MBC Number The MBC number generated by LN using the number group
that you enter in the Number Group for MBC field in the Engineering Data Management Parameters (tiedm0100m000) session. MBC Status The order status. Allowed values Position The MBC position number, which identifies the MBC
action. MBC Action The action of the mass BOM change (MBC). Allowed values Replace Type This field determines how the Quantity in EBOM field is handled in the Process EBOM Changes (tiedm3205m000) session if the MBC Action reads Replace. Include/Exclude E-Items This field determines whether the items you specify in the Include/Exclude E-Items (tiedm3121m000) session will be excluded from or included in the
MBC. If you select Include, only the E-items listed in the Include/Exclude E-Items (tiedm3121m000) session as related to this order will be changed by the MBC. Note If you select Exclude, but do not specify any items, all the E-items will still be included in the MBC. Include Use Up Materials If this check box is selected, LN also copies the
EBOM component's use-up materials, which you defined in the Use Up and Alternative Materials by Engineering BOM (tiedm2115m000) session. If you run the Generate EBOM Copy Data by MBC (tiedm3235m000) session or the Process MBC (tiedm3250m000) session, LN copies these materials to the Use Up and Alternative Materials in EBOM Copy Data (tiedm2125m000) session. Include Alternative Materials If this check box is selected, LN also copies the
EBOM component's alternative materials, which you defined in
the Use Up and Alternative Materials by Engineering BOM (tiedm2115m000) session. If you run the Generate EBOM Copy Data by MBC (tiedm3235m000) session or the Process MBC (tiedm3250m000) session, LN copies these materials to the Use Up and Alternative Materials in EBOM Copy Data (tiedm2125m000) session. MBC Action at Ref. Designator Level If this check box is selected, you can define an MBC action to add, replace, or delete reference designators. Use the New Reference Designator field and/or the Old Reference Designator field to enter reference designators. Old Comp. Type The item type of the component affected by the MBC. Old Component The component item that you want to delete when you carry out
the MBC action, or that you want to be replaced by another
component. Old Reference Designator The reference designator that you want to delete when you
carry out the MBC action, or that you want to be replaced by another reference
designator. Old Reference Designator The description of the reference designator. This can be, for
example, a code that expresses the location where you must mount a component
item. New Component Type The item type of the replacement or additional
component. New Component The replacement or additional component item. New Reference Designator The reference designator that replaces the old component when
you carry out the MBC action, or that you want to add. New Reference Designator The description of the reference designator. This can be, for
example, a code that expresses the location where you must mount a component
item. Length The length and width of the replacement component, or of the
component that is to be added in the EBOM. Length The length of the replacement component or of the component to
be added to the EBOM. Width The width of the replacement component or of the component that
is to be added in the EBOM. Number of Units The number of units needed of the replacement
component. Quantity in EBOM The net quantity of the component in the EBOM. If LN generates new EBOMs, it uses the value of the current field in combination with the MBC Action. There are three possibilities:
The quantity in the EBOM is calculated in the same way for components in the PBOM: Net Quantity = (Length x BOM Conversion Factor) x (Width x BOM Conversion Factor) x Number of Units / Conversion Factor If the component has no Width, the value of ( Width x 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. The BOM Conversion Factor is the conversion factor from the base unit to the BOM unit. This is derived from the BOM Unit of Measure.
Example
LN calculates the new Net Quantity: = 3 x (2 x 1) x (4 x 1) / 1= 24 = Quantity in EBOM If this is not possible (for example, no length was present), LN takes the value of Quantity in EBOM as the new value of Net Quantity. MBC Action = Replace Replace Type = + (Addition) Net Quantity (old) = 5 Net Quantity (new, in the Process EBOM Changes (tiedm3205m000) session) = (Quantity in EBOM) x (Replace Type) x ( Net Quantity (old)) = 24 + 5 = 29 All Actions Must Apply to Item If this check box is selected, the E-items selected in
the Include/Exclude E-Items (tiedm3121m000) session, to which all MBC
lines are applicable, will be considered for change. If this check box is cleared, the E-items selected in the Include/Exclude E-Items (tiedm3121m000) session, to which at least one MBC line is applicable, will be considered for change. Note The field relates to E-items which are both directly and indirectly listed in the Include/Exclude E-Items (tiedm3121m000) session. Example In the MBC Action (tiedm3120m000) session you define two MBC lines:
If the All Actions Must Apply to Item check box is selected:
If the All Actions Must Apply to Item check box is cleared:
Note If the Include/Exclude E-Items per Action check box is selected, this field is not available. 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.
