Hi Deekshitha,
NO.
Messages and transaction are not related at all. Transactions are 'entry points' for processing. Usually a transaction code is connected to a program an a screen. Starting there, any functions, programs, methods or transactions can be called. The called objects can do the same.
A message can be called directly in the program (This is what you found in function group MG11) or dynamically, selected via control tables or other methods.
You could check the function name of LMG11U05 and request a where-used-list. Then check transaction table TSTC for the programs found in the where-used-list. If you are lucky, it solves your question - at least partially. Because the message may be called elsewhere, too.
If not solved, please describe the situation in detail.
Regards,
Clemens
