How is WARNING mode merged for conflicting multiple profiles?

When a RACLIST is issued and multiple profiles in the grouping class are merged based on their member names, if one of the profiles is in WARNING mode, RACF® uses the setting (either WARNING or NOWARNING) for the first profile member or member profile of that name it encounters.

Note:

RACF processes grouping profiles before it processes member profiles.
A RACROUTE REQUEST=LIST selection exit can change the results.
The FILTER= or LIST= operands of RACROUTE REQUEST=LIST can change the results.
RACF ignores WARNING completely unless the issuer of RACROUTE REQUEST=LIST specified RELEASE=1.8 or higher on the macro invocation.
