Can I make changes or delete a UOM conversion after creation?

You can make changes to a UOM conversion if it doesn't impact open transactions in Oracle Fusion Materials Management or Oracle Fusion Costing. However, you can't delete the UOM conversion.

The application will validate if the conversion is used in any open transaction. If so, you won't be able to make changes to the conversions. If it isn't used in any open Oracle Materials Management or Oracle Costing transaction, you'll be warned that there could be possible impacts in other applications that aren't a part of the validation but won't be prevented from making the change.
