Maintenance that updates LMOD CAS9MNGR will generally update the assemble date for this module. Because this module is responsible for adding the CA-ENF health check during the ADD CHECK process, the date specified on the related ENF health check policy statement may become "outdated".
The IBM Health Check services are the services doing the date comparisons (not CAHCHECK). The two dates being compared are the DATE= in the HZSPRMxx parmlib member and the DATE= parameter on the HZSADDCK macro.
In the case of “CHECK(CA_CCS,CCS_ENF_SCREEN_VALIDITY”, the date used on the HZSADDCK macro is the assemble date of the CAS9MNGR module.
If the assembly date on the HZSADDCK is more recent than Date specified on the policy statement in HZSPRMxx, you get the “HZS0420E” message.
