Diagnosis
The conversion routine &V2& was deleted for characteristic &v1&.

System Response
When making an entry in variable screens, you must enter the correctinternal values.
Example: For the ALPHA conversion routine, you need to enter
0000001212, and the zeros were then added when converting to
internal values.
The values are not checked or automatically converted.
Example: If in the ALPHA conversion routine, the values
0012 and 12 were loaded in an 8 character field,
they were converted into the same internal value 00000012.
Now, the values are updated in the same form as when they arrive, thatis, as different values.
Note that the conversion routine cannot be switched off again
without further action.
If master data already exists for characteristic &V1&, then you have to
use the transaction RSMDEXITON to switch on
conversion routine &V2&. All affected tables are converted there when
you switch on conversion routine &V2&.

Procedure
Check whether the entry conversion can be disregarded and make sure noambiguous values were loaded that actually represent the same value.Only then should you delete the conversion exit.
