How to trace the message in which line of program used?

Question

Dear fellows,
       Many times when we run a t-code (especially standard t-code), it will return many message log. but when we debug the t-code to trace the error message, it is difficult to find why raise this error message. Even we can not find in which line of program. We can not use the where-to-used list in SE91 to trace, because it is not written like this:       message 033(FD) TYPE E.
       For example in validation(GGB0)  we use some message, but when this message come out, we didn't know this message in which program raise.  And it also can not be traced using message at in debug mode.
       In many case, the way of using message is not easy to be trace , but if we can find which line of program to raise this message, would help a lot for finding the cause problem.
       Is there any tool for us to trace message ?
       Thanks for your sincerely answer!

Hello All,
If the message log is filled like this
  L_S_MSG-MSGTY     = 'E'.
  L_S_MSG-MSGID     = 'BL'.
  L_S_MSG-MSGNO     = '303'.
  L_S_MSG-MSGV1     = '007'.
Can you trace this message by putting a watch-point/break point? I guess no! If some has YES as answer, please feel free to correct me.
That is why whenever filling a message log/return table it is important that we ensure that the message can be traced back using "where-used". Hence the usage of MESSAGE...INTO (or the pre-historic, IF 1 = 2 ... MESSAGE ... ENDIF) construct.
