I am having problems doing MRO in CICS from a CA ACF2 region to non-CA ACF2 region. I get various errors such as AXFW abends.
Doing MRO between CICS regions take special control blocks to be passed so that important information is sent properly. In the CA ACF2 for CICS parameters, there is a section for MRO. The default format is FORMAT=ACF2. This only works for CA ACF2 to CA ACF2 regions. If you are doing MRO to a CA Top Secret or IBM RACF region, then you need to set the parameter to FORMAT=CICS.
