| MBC Action (tiedm3120m000) |  |
| Use this session to list the actions defined for a mass bill of material change (MBC). If the MBC status is In Design, you can modify the data in this session. If you add a component using an MBC action, you cannot delete or replace that component using another MBC action linked directly to the same MBC. To work around this restriction, first delete and then add the same component using the same MBC. The added component can have a different EBOM quantity from the original. In that case, the value in the Quantity in EBOM field is used as an absolute quantity, regardless of the value of the Replace Type field. You can perform the following actions to an EBOM component: Add Delete Replace If you select Replace, you can use the Replace Type field as an operator to alter the Quantity in EBOM. If the Include/Exclude E-Items per Action check box in the MBC (tiedm3110m000) session is selected, you can start the Include/Exclude E-Items (tiedm3121m000) session from the Specific menu to define a list of E-items that are included or excluded when using the MBC action.

Fields | Description
MBC Number | The MBC number generated by ERP 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.
Position Number | The MBC position number, which identifies the MBC action.
MBC Action | The action of the mass BOM change (MBC). Allowed values Possible 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, ERP 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, ERP LN copies these materials to the Use Up and Alternative Materials in EBOM Copy Data (tiedm2125m000) session. Related topics To use up remaining stock of outdated items
Include Alternative Materials | If this check box is selected, ERP 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, ERP 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. Related topics Reference designators and MBCs
Component 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. Related topics Reference designators and MBCs
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.
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. Related topics Reference designators and MBCs
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 ERP LN generates new EBOMs, it uses the value of the current field in combination with the MBC Action. There are three possibilities: Delete. The field is not applicable. Add. The value of this field is taken to be the value of the Net Quantity field in the Process EBOM Changes (tiedm3205m000) session. 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. ERP 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. Replace. The field is calculated using the Net Quantity as a value and the Replace Type as a mathematical operator. If possible, ERP LN first calculates the Net Quantity using the formula provided earlier. If ERP LN can not calculate the Net Quantity using the formula provided earlier, ERP LN uses the value of the current field to calculate Net Quantity field in the Process EBOM Changes (tiedm3205m000) session using Replace Type as a mathematical operator. Example
Number of Units | 3
Length | 2
Width | 4
BOM Conversion Factor | 1
Conversion Factor | 1
ERP 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), ERP 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 Related topics Calculating net quantity Engineering BOMs To change EBOMs - Automatic procedure
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: Delete Metal-Wheel. Replace Metal-Pedal with Plastic-Pedal. If the All Actions Must Apply to Item check box is selected: The MBC is carried out for the components of Red-Bicycle, because all the lines are applicable. The MBC is not carried out for Blue-Bicycle or Yellow-Bicycle, because only one of the lines is applicable. If the All Actions Must Apply to Item check box is cleared: The MBC is carried out for all the bicycles, because each bicycle contains a component to which an MBC line applies. 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.
