Message text: Inconsistent new value(s) - doesn't follow required settings
You are performing a material number conversion in the system and also
wants to reset(cancel) the lexicographic  indicator.
<ZH>Caution</>
In transaction OMSL(Material Number Format), it is only possible to set
or reset (cancel) lexicographic indicator if no numeric material numbers
have been used yet in the system since they would no longer be
interpretable after setting or resetting this indicator.
Currently, new value is numeric in the mapping and this type of value is
not allowed to switch uncheck the lexicographic indicator
Scenarios:
Only alphanumeric exists: If all the materials are alphanumeric in the
system then the lexicographic indicator can be unchecked in the material
number format customization (transaction: OMSL) and then required
conversion should be using scenario Mapping Table OR Mapping Table and
Number Range
Numeric material exists:
If target new value for all of them is alphanumeric then do the
conversion in the system with scenario Mapping Table or Lexicographic +
Mapping Table, then the lexicographic indicator can be unchecked in the
material number format customization (transaction: OMSL)
If target new value for any of them numeric then open an incident in
component CA-LT-CNV.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
