Defining E-item by MBC

You can only use an MBC to modify an E-item if its status is Approved by Engineering or Approved by Production. The revisions you define or link to the MBC are generated by the Process EBOM Changes (tiedm3205m000) session.

When you modify E-items using an MBC, LN carries out a number of tests. These tests are described in the Changing EBOMs - Automatic procedure topic.

  • Consequences of entering an E-item

    When you enter a new E-item, the following fields are filled:

    • Old Revision
    • Effective Date of New Revision (filled with the value of the current date).

  • Consequences of entering a revision

    If it is a new revision, the revision is generated in the Engineering Item Revision (tiedm1100m000) session, and LN fills the MBC Number field. If the new revision is already present in the Engineering Item Revision (tiedm1100m000) session it will be linked to the MBC if:

    • It is not linked to another MBC
    • Its status is not In-design or Frozen

  • The All Actions Must Apply to Item check box

    If the All Actions Must Apply to Item check box is cleared, a set of E-items is recorded for each MBC line. The value of the Position in this session is equal to the value of the Position in the MBC Action (tiedm3120m000) session.

Note: 

The way that this session works is critically affected by the All Actions Must Apply to Item check box. If this check box is selected, all E-items for the entire MBC are recorded under Position 0.

  • The New Revision field

    LN ensures that the New Revision field keeps the same value in this session for a particular E-item for each MBC line. This is necessary because all changes made with an MBC must result in only one new E-item revision.

You can start the Engineering Item Revision (tiedm1100m000) session in the appropriate menu.
