This number is generated by LN using the number group you enter in the Number Group for MBC field of the Engineering Data Management Parameters (tiedm0100m000) session.
MBC (tiedm3110m000)Use this session to display, define, and modify mass bill of material changes (MBCs).
MBC Number This number is generated by LN using the number group you enter in the Number Group for MBC field of the Engineering Data Management Parameters (tiedm0100m000) session. MBC Creation Date The date on which the MBC was created. Approval Date by Engineering When you changed the Order Status to Approved by Engineering. Approval Date by Production The date when the Order Status was changed to Approved by Production. Effective Date for Revisions created by this MBC If the Manual Revision Numbering check box in the Engineering Data Management Parameters (tiedm0100m000) session is cleared, you must specify the effective date for the revisions that are created automatically by the MBC. If the Manual Revision Numbering check box is selected, this effective date cannot be modified. When you finalize the MBC, this date becomes the effective date for the PBOM lines. Finalization Date The date on which you used the MBC in the Finalize Engineering Data (tiedm3240m000) session, and the MBC status became Finalized. Automatic Generation of EBOMs If this check box is selected, you can use an MBC to change and approve EBOMs. You must define actions to change the EBOMs in the MBC Action (tiedm3120m000) session. If the actions are performed, the E-item revisions are automatically linked to the MBC, after which the revisions can be approved. If this check box is cleared, you do not use an MBC to change EBOMs. You manually change the EBOMs, then manually link the revisions to the MBC, and finally use the MBC to approve the revisions in one go. Define Include/Exclude E-Items by Action To an MBC, actions are linked that can change the BOM of an item. The items that are effected by the actions are defined in the Include/Exclude E-Items (tiedm3121m000) session. If this check box is selected, you specify for every action separately which items are effected by the action. To do so, select the action in the MBC Action (tiedm3120m000) session, and start the Include/Exclude E-Items (tiedm3121m000) session from the appropriate menu. Now you can define the items that are effected by the action. If this check box is cleared, you specify a set of items in the Include/Exclude E-Items (tiedm3121m000) session. All actions that you define for the MBC apply to that set of items. All Actions Must Apply to Item To an MBC, one or more actions can be linked, which are defined in the MBC Action (tiedm3120m000) session. The actions can change items that are defined in the Include/Exclude E-Items (tiedm3121m000) session. An action can add, replace, or delete a component of a specific item. If you define a set of actions, it can be the case that all actions have an effect on a specific item, or that only part of the actions apply to an item. If this check box is selected, only items in the Include/Exclude E-Items (tiedm3121m000) session to which all actions apply are changed by means of the actions. The items to which only part of the actions apply are not changed. If this check box is cleared, the items in the Include/Exclude E-Items (tiedm3121m000) session to which all actions apply are changed by means of the actions. However, also items to which only part of the actions apply are changed by the actions. Note If the Include/Exclude E-Items per Action check box is selected, this field is not available. Example In the MBC Action (tiedm3120m000) session two actions are defined:
Two items are included in the Include/Exclude E-Items (tiedm3121m000) session:
If the All Actions Must Apply to Item check box is selected, only item A is changed by the actions, because both actions apply to item A. Although the first action also applies to item D, the action is not carried out for item D, because not all actions apply to item D. If the All Actions Must Apply to Item check box is cleared, item A as well as item D is changed by the actions. For item A both actions are carried out; for item D only the first action applies and is consequently carried out. Include/Exclude E-Items Use this field to define whether E-items are either included or excluded when performing an MBC. If you select Include, the MBC affects the items. If you select Exclude the MBC does not affect the items. You must define the items that are included or excluded in the Include/Exclude E-Items (tiedm3121m000) sessions. Note If you select Exclude, but do not specify any items in the Include/Exclude E-Items (tiedm3121m000) session, all E-items are still included in the MBC. Order Status You can alter the status by selecting an option from the appropriate menu. Allowed values MBC Reason The reason for the change. You can define MBC reasons in the MBC Reasons (tiedm3104m000) session. Engineer Responsible The code of the person who is responsible for the MBC. Engineer Responsible The name of the individual selected for the Engineer Responsible field. CHM Control If this check box is selected, an approval procedure is linked to the MBC. You must complete the approval procedure in Change Management in Data Management. In Process by Change Management If this check box is selected, an approval procedure for the MBC has started in Data Management. You must first complete the approval procedure before you can approve the MBC for production. Effective Dates by Change Order If this check box is selected, the effective date on the MBC is set during the approval procedure in Data Management. This effective date is used as effective date on the BOM lines after the E-item data is copied to the PBOM. If this check box is cleared, you must enter the effective and expiry dates manually in the MBC, although Data Management is still used to approve the MBC. Multiple Change Orders allowed If this check box is selected, you can link multiple change proposals (multiple COs) to the MBC. The first change proposal that is approved, also approves the MBC. If this check box is cleared, you can only link one proposal to the MBC. MBC Text If this check box is selected, a text is present.

The reason is that it is possible that the link between the E-items and the MBC might not be deleted if an MBC is cancelled. You can only use this command if the MBC has the following statuses:
