Engineering BOM for assembly production

You can create an Engineering BOMs for engineering modules.

To create an engineering bill of material (BOM) for engineering modules:

  1. Start the Generate EBOM Copy Data (Multilevel) (tiedm1230m000) session. Generate copy data for an EBOM for an engineering item of type Engineering Module.

  2. Start the Finalize Engineering Data (tiedm3240m000) session. Finalize copying the data which you have generated in the previous step.

Note: Items of the type Manufactured or Product with the default supply source set to Assembly are produced in the Engineering Data Management module. These items are considered phantom subassemblies: they are not copied to Assembly Control or Job Shop Control, and are not defined in the Items (tcibd0501m000) session.

Flattening

The copy process flattens the structure of the engineering bill of material (BOM). Flattening means all intermediate phantom subassemblies, are skipped. Multilevel BOM relations are reduced to a single level relation, with quantities multiplied and effective dates combined.

This figure shows an example of flattening:

The following multilevel BOM relations are reduced to a single level relation:

  • Module A -> Phantom B -> Part T

    Combined to Module A -> Part T

  • Module A -> Phantom C -> Phantom F -> Part V

    Combined to Module A -> Part V

  • Module A -> Phantom C -> Phantom F -> Part W

    Combined to Module A -> Part W
