How to build a call graph for a function module?
A while ago during documenting legacy code I found out there is a tool for displaying call graph (call stack) of any standard program. Absurdly I wasn't aware of this tool for years :D
It gives fancy list/hierarchy of calls of the program, though it is not a call graph in a full sense, it is very helpful in some cases.
The problem is this tool is linked only to SE93 so it can be used only for transactions. I tried to search but didn't find any similar tool for reports or function modules. Yes, I can create a tcode for report, but for function module this approach doesn't work.
If I put FM call inside report and build a graph using this tool, it wraps this call as a single unit and does not analyze deeper. And that's it
Anybody knows a workaround how we can build graph for smth besides transaction?
The cynic in me thinks RS_CALL_HIERARCHY was left to rot. Sandra is right, it definitely used to work. Once OO came to abap, interfaces and dynamic/generic code became possible. So a call heirarchy based on static code analysis was pushing proverbial up hill.
IMO the best way to solve this is a FULL trace and then to extract the data from the trace. There are even external tool that do that. This is of course, still limited as running a trace on every execution path can be very time consuming. Did I hear someone say small Classes please ?
Trans SAT. Make sure teh profile you use isnt aggregating, and measure the blocks you are interested.
Now wade you way through the trace. https://help.sap.com/doc/saphelp_ewm93/9.3/en-US/4e/c3e66b6e391014adc9fffe4e204223/content.htm?no_cache=true
