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

Possible values

Position

The MBC position number, which identifies the MBC action.

MBC Action

The action of the mass BOM change (MBC).

Allowed values

ECO Activity Type

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:

  • 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. 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, LN first calculates the Net Quantity using the formula provided earlier. If LN can not calculate the Net Quantity using the formula provided earlier, 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 Units3
Length2
Width4
BOM Conversion Factor1
Conversion Factor1

 

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:

  • 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.
