I need to find how entries are inserted in FAGL_SPLINFO in the code through tcode FB05 because there are couple excess entries goes to the table(HANADB EHP7, core 745, copy of the production system EHP6 where it goes normal). I can't find it by myself through the debugger and whereuse button and keywords "UPDATE,INSERT,MODIFY" in debugger. So if anybody know how entries are inserted in the table i would appreciate it.
