| # Changing EBOMs - Manual procedure If you want to change and approve the BOM of an engineering item (E-item), you can do this in three ways: Change and approve EBOMs by means of an mass BOM change (MBC). For more information, refer to Changing EBOMs - Automatic procedure Make changes in EBOMs manually, and approve the EBOMs by means of an MBC. For more information, refer to Changing EBOMs - Semi-automatic procedure. Change and approve the EBOM manually. For more information, refer to the procedure below.. Step 1. Engineering Item (tiedm0110m000) Define a new E-item in the Engineering Item (tiedm0110m000) session, or transfer an existing production item to Engineering Data Management (EDM) by using the Copy PBOM to EBOM (tiedm0205m000) session. If you want to implement an approval procedure for the E-item, select the CHM Control check box in the Engineering Item (tiedm0110m000) session. You must use Change Management in Data Management to carry out the approval procedure. Step 2. Engineering Item Revision (tiedm1100m000) Select the E-item in the Engineering Item (tiedm0110m000) session, and start the Engineering Item Revision (tiedm1100m000) session in the appropriate menu. A new revision is now defined for the E-item. The revision status is In Design. Step 3. Engineering BOM (tiedm1110m000) Select the E-item revision in the Engineering Item Revision (tiedm1100m000) session and start the Engineering BOM (tiedm1110m000) session. You can now manually define or change the EBOM according to your wishes. Step 4. Approve for engineering If you have carried out the changes in the EBOM, you can approve the revision for engineering. To do so, select the revision in the Engineering Item Revision (tiedm1100m000) session, and click Approve by Engineering in the appropriate menu. The revision status changes to Approved for Engineering to indicate that the EBOM is approved. Step 5. Engineering Item - Item Relationship (tiedm1101m000) If desired, you can now define for which (production) item(s) the revision is meant. Select the revision in the Engineering Item Revision (tiedm1100m000) session, and click Relationships in the appropriate menu. The Engineering Item - Item Relationship (tiedm1101m000) session is started. In this session, you can define one or more items. This can be existing items, selected from the Items - General (tcibd0501m000) session, or new items for which you enter the item name. Note that it is not mandatory to define relationships manually in this stage. Item relationships can also be automatically generated in step 8. For more information, refer to step 8. Step 6. CHM control If your E-item is CHM-controlled, that is, if the CHM Control check box in the Engineering Item (tiedm0110m000) session is selected, you must complete the approval procedure in Data Management. Otherwise, you cannot approve the revision for production as described in the next step. Step 7. Approve for production Approve the revision for production. Select the E-item in the Engineering Item Revision (tiedm1100m000) session, and click Approve by Production in the appropriate menu. The revision status changes to Approved for Production. Step 8. Copy Engineering Item to Item (tiedm1201m000) Copy the E-item data for production. Select the E-item in the Engineering Item Revision (tiedm1100m000) session, and click Copy Engineering Item to Item in the appropriate menu. The Copy Engineering Item to Item (tiedm1201m000) session is started. The source item in this session is the E-item you are working on. In the Item field, you can enter one of the items you defined in Engineering Item - Item Relationship (tiedm1101m000) session. However, if you did not define any relationships, you can enter a new name or the same name as the source item in the Item field. A production item with this name is automatically created. The newly created product item is also displayed in the Engineering Item - Item Relationship (tiedm1101m000) session. Note that you must enter an item group in the Copy Engineering Item to Item (tiedm1201m000) session to get defaults for the newly created items. Step 9. Generate EBOM Copy Data (Multilevel) (tiedm1230m000) Select the E-item in the Engineering Item Revision (tiedm1100m000) session, and click Generate EBOM Copy Data (Multilevel) in the appropriate menu. The Generate EBOM Copy Data (Multilevel) (tiedm1230m000) session is started. You must enter the source item and the target item. If you click Generate, the E-item’s EBOM data is collected and put in a buffer for copying. If desired, you can now make some changes using the EBOM Copy Data (tiedm1120m000) session, which you can start from the Engineering Item - Item Relationship (tiedm1101m000) session. Step 10. Finalize Engineering Data (tiedm3240m000) Select the E-item in the Engineering Item Revision (tiedm1100m000) session, and click Finalize Engineering Data in the appropriate menu. The Finalize Engineering Data (tiedm3240m000) session is started. The EBOM is copied to the (new) production item. Step 11. Archive Engineering Data (tiedm1250m000) If desired, you can archive the E-item data in the Archive Engineering Data (tiedm1250m000) session. Note You can reset the revision status by selecting the revision in the Engineering Item Revision (tiedm1100m000) session, and then click Reset Revision Status from the appropriate menu.
