What causes this issue?

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?

After the conversion is finished, check the table UCM2000 and the log.
Not all existing entries could be converted.
Decide if you still need these entries. If you do need them
, correct the errors that prevented the conversion (as stated in the
log).
Start program UCCM351 again so that the corrected entries in UCM2000 can
be converted.
