UoM of a BOM Component for Subcontracting Process

Hi Experts,

We have a component that its UoM is setup incorrectly where the base UoM (EA) is not the smallest unit.

With that said, here is the situation.

This component is being used to build parent material A, B, etc.

The qty. needed to build material A is 1/4 EA and 1/3 EA for material B.

To reflect this, I setup alt. UoM, SH (4 SH = 1 EA) and PAC (3 PAC = 1 EA).

I then updated a BOM for material A with 'SH' as the component's UoM.

Next, I tried to update a BOM for material B with UoM 'PAC' then SAP issued this error.

"Unit of measure PAC not supported for material 'B' in plant ####" (message # 29175)

After a research, I found that the Unit of Issue (UoI) in the master need to be set as 'PAC' to avoid the above error.

So I tried to change UoI in the master and got another error message.

"The unit of issue cannot be changed because the material is used in a BOM" (M3214)

I deleted all existing BOM of a component having 'SH' as UoM but still getting the same error M3214.

Is there a way to maintain a component in BOMs with more than one UoM?

The bottom line here is to update subcontracting POs with the correct BOM.

Any input or suggestion would be very appreciated!

Regards,
Eddie

    The message talks in general about BoMs, not just about BoMs with unit SH.

    See as well the detail of the message

    Hello Eddie,

    For material where the unit is w/o dimension, I don't think this is possible. I would recreate the materials/BOM etc...

    There are some threads on this topic :

    Check these notes :

    47732 - Material is still used in bill of material

    338145 - Incorrect maintenance of AUSME cannot be corrected
