Hello Michael,
I think there is a logic issue producing your 'No result'.
The UPUPRF search criteria are looking for specific user IDs that consist of just those letters. Combined with the AND - it means that all of the criteria must be met to produce results. I would presume that you want IDs that are 'E' OR 'M' OR 'P' OR 'S' to be listed - not AND which looks for a user ID that will satisfy all of those single letters (which is not logically possible).
Also, since you used the EQ test - it will only look for a user ID that is 'E' OR 'M' OR 'P' OR 'S'. You might want to change that test to LIKE - 'E%' OR 'M%' OR 'P%' OR 'S%' to look for IDs that start with those letters (perhaps - just a guess).
Plus there is Jack's method as well - it takes out the step of the DSPUSRPRF command to an output file, giving you a view at that information. It has been around since V7R3 (at least) - so depending on the age of your OS, it might be available.
The links give examples on the SQL statements to get at that data. A little experimentation should get you what you are looking for using that service as well.
Good Luck!
