Mainframe, MVS and zOS Discussion

For a VSAM file, this error can occur if the file is empty. If that's the case, then you need to load a dummy record into the file. This can be done programatically or you can use the REPRO statement under IDCAMS to get the record in there.

Have you considered the possibility that the file might be empty, especially if it's a VSAM file, and have you tried loading a dummy record into it?
