You’ll find details of the CEMT transaction in the CICS Supplied Transactions manual and extensive details about CEBR, CECI, and CEDF are in the CICS Application Programming Guide.
Two of these transactions (CEDF and CEDX) enable you to use the Execution Diagnostic Facility (EDF); it allows you to inspect and change variables that your application gives and receives from CICS. This is described in detail in EDF: Execution Diagnostic Facility. Within your organization there are likely to be other debugging aids available, for example, line-by-line source debuggers for finding pure application errors, especially during development, rather than that result of passing bad data to CICS; this information should be readily available from other development and technical team members.
When carrying out problem determination, it is worth noting details of actions taken and results obtained in a log to provide information to other people that you may need to consult.
