Defined the TRANSID specified in the CICSOPTS assembly as a CICS transaction invoking the new IDMSINTC load module.
If it is already defined make sure it is invoking the correct IDMSINTC module.
For example, If the new IDMSINTC module is called IDMSINT2 and the TRANSID is INT2, you need to define a new CICS transaction INT2 to invoke the new module IDMSINT2.
See CAGJSRC library member CICSCSD for how to define the IDMSINTC transaction and program.
