REQTYPE=DEFER (the default), requires that XCF suspend the task while it serializes and accesses the most recent data for the following REQINFO types:
  • REQINFO=GROUP
  • REQINFO=CF
  • REQINFO=CF_ALLDATA
  • REQINFO=STR
  • REQINFO=STR_ALLDATA

IXCQUERY processing might involve referencing or updating the CFRM active policy to reflect the operation that has been requested. When invoking this macro, be aware of the I/O to the CFRM couple data set that might be generated.
