Message text: Value-based inventory management possible for RMA site: Customer &1
The system has been set up to allow for value-based inventory management

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
This is an error, because RMA does not work together with value-based

If this is the case, make sure that all RMA-relevant plants - that is,
plants with an assigned RMA profile - are assigned to the above
inventory management profile.
