UBE: Retrieve of UBE file failed. The file may not exist on Enterprise Server.

Dear All,

I'm facing the issue in PY900 the issue is -

GO to WSJ --> Select any one of the job (R0006p ) --> Go to Row exit and select the View Logs --> on View logs screen select Logging (Jde.log) and after click OK button the following message appears  " UBE: Retrieve of UBE file failed. The file may not exist on Enterprise Server. ".

When the ube is running at that time the logs we are getting but when it is done the logs is not coming out the above message is displaying.
