Paul, you should be able to issue the following command D PROG,LPA,MOD=module_name to display the diagnostic data associated with the module.
The module name should be liisted in the CSV550I message. According to IBM: This is used by the system and IBM Support <https://www.ibm.com/docs/en/ibmid?topic=contact-support> to track module modifications, APF authorization states, or maintenance levels.
