• Message number: 031

• Message text: You are carrying out a standard material number conversion

What causes this issue?

Choosing this scenario makes sense if you want to change all values in a
number range in accordance with a rule. If the number range for the new
material numbers does not yet exist in Customizing, you must create it
first. In addition, you can change individual material numbers by
defining individual mapping entries for them in a mapping table. For all
material numbers for which you define individual mapping entries, these
individual entries take priority over the number-range-based mapping.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Make sure that the mapping is maintained correctly and the number ranges
are set accordingly.
