The specified map was not found in the map set load module. The most likely cause is an incorrect map set load module.
Dump the Error log (DFHMAERF). Check the fields Mapset and Map in the dump for the program reporting the error. Check the CICS® RPL concatenation to determine if there is a program or map set load module of the same name, as specified in the Mapset field, higher in the concatenation. Also check to insure the correct map set load module is defined to the CICS Service Flow Runtime router region.
