Question:  

Should the CA ACF2 JES2 exits precede or follow any user JES2 exits in the JESPARMS?

Answer:  

A CA ACF2 JES2 exit must appear before any user exit that depends on CA ACF2 having set up data in the JCT extension or any other JES2 control block. The order does not matter if the user exit has no dependency on CA ACF2.
