BOM Transfer and Assemblies Used More than Once 

Use
 In general assemblies that are used more than once in the same bill of material pose no problem for BOM transfer. However if you use sales order BOMs, errors in the calculation of quantities could occur in particular circumstances. Material BOMs and WBS BOMs are not affected.

Assemblies Used More than Once in Order BOMs

Before you trigger a BOM transfer to the Project System, ensure that all assemblies you transfer, can be uniquely identified. This guarantees that the system determines the quantities for all items correctly. This is only the case if no assembly in the multi-level BOM is used on more than one node.

Activities

Check in order analysis, whether one or more assemblies are used several times in the multi-level BOM.

  1. Choose Logistics ® Production ® Master data ® Bills of material ® Bill of material ® Order BOM ® Order browser.

    2. The Edit Order BOM screen appears.

  2. Choose Order analysis.

    3. The List of Results for the Analysis screen appears..

  3. Choose the Multiple assemblies tab page.

The assemblies listed on this tab page are used more than once in the multi-level BOM for the sales order item.

If an assembly is used more than once, replace the material on the individual nodes, so no two BOM headers in the multi-level BOM have the same material number.

For configurable assemblies use instantiation in variant configuration to do this.

For non-configurable assemblies use material replacement in the order browser.
