How to change unit for many materials

Former Member

Hello Everyone,

I imported around 500 materials from XML file to SAP Byd productive database.

During import all was OK, SAP ByD haven't asked for anything to confirm.  Result of import was "no error".

Then after import, I've notice BIG problem.

In my XML file I used unit "kg" but after import all materials has unit  "kg90%sdt  - Kilogram of substance 90 % dry" ?!?

This unit kg90%sdt was assign as base UoM, inventory UoM, planning UoM, inventory UoM ....

In SAP interface fields UoM are grey - not possible to change, not possible to delete materials even though were not used in any other document.

How to change all UoM to "kg" ?

Any help appreciated

Best Regards,

Hello Pawel,

Once the Base UoM is activated for Logistics, Planning, Availability Confirmation, and Valuation then it is not possible to change it. The system will not allow you to change the UoM, because system will become inconsistent if that material is used.

You have following options:

1) UoM conversion needs to be maintain in general tab For example: 1kg = 1box

2) You can Block all materials (you can use Mass change for this) and import them with correct UoM (with different ID's....). Maintain Quantity conversions for the UoM that you want.

Let us know in case of any clarification.

Thanks & Regards,

Quantity conversion doesn't make any sense.

I just faced the same issue and kg and kg90%sdt are equivament UoM.

Second approach changing all the IDs in a productive database will affect all dependent migration templates which is not a good option for the customer.
