EQA9937W XPCFTCH MEA conflict- XXXXXXXX: YYYYYYYYY

Explanation
z/OS® Debugger is reporting that another CICS® XPCFTCH global user exit has set a modified entry address
(MEA) and prevented z/OS Debugger from any possible
debugging of a specific non-Language Environment®
program. XXXXXXXXX can be either : 'Prior MEA' or 'Program' or 'Transid'
and YYYYYYYYY is the data associated with each. Note this message is only
issued once when this occurs the first time after the z/OS Debugger
CICS exits are activated. Subsequent conflicts are not
written to the CICS JES log.

Programmer response
Multiple XPCFTCH exits running in the same CICS region
which can each set the MEA and return to CICS is usually not
recommended. For z/OS Debugger, you will be
unable to debug any non-Language
Environment programs
when the MEA was changed by another XPCFTCH exit. The behavior of z/OS Debugger in this kind of scenario will likely be
unpredictable.
