Message . . . . : Previous conversion of Model XXXX not completed
CAUSE: A previous execution of YAPYMDLCHG for model XXXX failed to complete,
so model contains work files whose names begin with 'Z'. RECOVERY: (1)
Determine cause of failure and correct error. Consult customer support if
uncertain. (2) Restore model from a backup and re-run YAPYMDLCHG command.
The Y2E0028 on a model, when converting models using YAPYMDLCHG is typically caused by Z* files in the model library. Normally there will be just one single Z file 'ZJOBLSTRFP' in the model library. You will need to delete ALL the Z files from the model library (see the model reference from the joblog), then rerun the YAPYMDLCHG command to resolve the error and convert your model.
