In our system we had an output device "zlocal" with a format "z_60000_80". This was to allow a user to download a report which was generated in the background and for it to only contain one header so that I could easily download into Excel. In August we applied support stacks to our system. Due to OSS Note 2425093, the output now needs to be less than 10000 lines. We have defined a new format "z_9999_80". The problem that we now have is we are getting message PT002 "format is not defined for output device. Where do we associate format with output device?
