Compare BOMs with different categories.
In transaction CS14, we can compare BOMs. But in the initial screen, the primary BOM and secondary BOM are material BOMs by default.
Please go to the Goto->Primary/Secondary BOM Category in menu bar, here you can select different category for the two BOMs.
The categories can be chosen are: Material, Document, Equipment, Functional Location, Production Order, Sales Order and Project.
I also list some related notes for transaction CS14, BOM comparison.
2017544 – CS14: unable to navigate to primary BOM component if parameter effective change numbers are used.
1398101 – CS14: No search help (F4) on the change number field.
1875482 – Header of CS14 compare list can’t be exported to excel.
Hope this information is useful for you.
