| # Generating EBOM Copy Data (Multilevel) ERP Enterprise will not generate copy data for the lower levels of the EBOM if copy data already exists (for example, from copying a single-level BOM with the EBOM Copy Data (tiedm1120m000) session). ERP Enterprise will not generate copy data of a E-item revision if: The revision which you selected does not have the status Approved by Production (see the Status field in the Engineering Item Revision (tiedm1100m000) session). The E-item revision's unit is different from the item's unit (see the Unit field in the Engineering Item Revision (tiedm1100m000) session). The E-Item type is different from production item type. There is no valid revision of a component E-item of the EBOM with the status Approved by Production. For each single-level EBOM you can check or change the result of this session using the EBOM Copy Data (tiedm1120m000) session. You can also use the EBOM Copy Data (tiedm1120m000) session to copy single-level EBOMs to production BOMs using the generated copy data. If neither a relationship nor a target item exists, ERP Enterprise uses this session to make a relationship between an E-item revision and another item. If you are using customized items, you must set the Customize Copied Item check box in the Engineering Data Management Parameters (tiedm0100m000) session to give the desired result.
