| # Modifying Engineering Item Revision Engineering is performed per revision. You can manage and define new revisions in Engineering Data Management. Revisions To define new revisions for an e-item, click the Add a New Engineering Item Revision button. You can insert multiple revisions that have the In-design status. You cannot insert a new revision if the previous revision is linked to an MBC, and EBOM changes have not yet been processed for that MBC. To select a a different e-item for which you can define new revisions, click the Find Engineering Item Revision button. The e-item must be defined in the Engineering Item (tiedm0110m000) session. If the revision is valid, it can affect a standard or customized item. The revision is valid if: The the revision's status is Approved by Production. The revision is linked to a standard item or to a customized item defined in the Engineering Item - Item Relationship (tiedm1101m000) session. The revision's current date falls between the effective date and the expiry date. The default effective date of a new revision is the current date. This date is used as the expiry date for the previous revision. To delete a revision with In-design status, select the revision and then select Delete Engineering Item Revision from the Edit menu. You cannot change the status to Approved by Engineering or Approved by Production if the revision is created by an MBC for which EBOM changes are not yet processed. appropriate menu You can alter the status of an e-item revision in the Status field to: Frozen, if the revision status is In-design. In-design, if the revision status is Frozen. Approved by Engineering, if the revision status is Frozen or In-design. Approved by Production, if the revision status is Approved by Engineering or In-design. Canceled, if the revision status is Approved by Engineering. If you cancel an MBC in the MBC (tiedm3110m000) session, all the revisions that are linked to that order are also cancelled. In-design revisions can be deleted and Canceled revisions can be archived. You can not cancel a revision that is Approved by Engineering if the revision is linked to an MBC for which the EBOM changes are not yet been processed. You can also start the following sessions from the appropriate menu: Archive Engineering Data (tiedm1250m000) Copy Engineering Item to Item (tiedm1201m000) Generate EBOM Copy Data (Multilevel) (tiedm1230m000) Finalize Engineering Data (tiedm3240m000) Engineering BOM (tiedm1110m000) Engineering Item - Item Relationship (tiedm1101m000) Reference Designators by Engineering Item (tiedm0120m000) Reports If you click Print button, you can select a session to produce reports about revisions: Print Engineering Item - Revisions (tiedm1400m000).
