CEMT I TRANS PRO(????????)
will give you a list of all transactions that have the program as the primary program. You cannot know which primary programs use a given subroutine without tracing through source code to identify the subprogram.
You could also extract the RDO definitions into a file using the CICS utility and find all occurrences of the program in the file -- but again this is only transactions that have the program as the primary program.
