CN33 BOM transfer

We transfer BOM to Builder. When in the Builder we enter some figures in the SORTF field of the Component. (drawing no). Then we change the BOM and want to transfer it again using CN33. SAP regard all items where we have entered values in this SORTF field as manually entered materials and import these items again into the Builder.

Can anyboddy explain why and where these settings can be found.

Some how SAP regard certain field as part of the unique key - and in our case SORTF is one of these

    go to SPRO

    PS -> Materials -> Bill of Material Transfer -> Define Fields in BOM and activity as ref points

    Field name for the reference field in the BOM item

    Field in a bill of material that you want to link to a field in a network. The field in the bill of material becomes the reference point

    You use the reference point to create a link between a network activity and a bill of material item so that changes in the bill of material automatically effect:

    Compoments that are assigned to the network activity

    Purchase requisitions for the component if present


    If you do not know the name of a field, use the F1 help in the maintenance transaction for the bill of material or network. You will find the field name in Technical info.

    You can also use transaction SE12 to display the data structure of the objects

    STPOX: BOM item

    AFVGD: Network activity

    and consequently to identify fields in both objects that have the same structure (type/length).

    It is also possible to use customer enhancements to create your own fields in the network activity and the BOM item. For more information,

    refer to Customizing for PS and PP.


    Object Data field Technical name

    BOM item Sort field SORTF

    Network activity Third user field USR02

    These fields are both alphnumeric fields with a length of 10 characters.


    These are generally only defined once. They usually do not have to be changed afterwards.
