Debugging in production instance

The main concern with debugging authorization in PRD is with the replacement
of variable values. For example, if a user isn't authorized to create P/O's,
they could start the debugger then enter tcode ME21. The user can then
single step past the authority check. If the check fails, SY-SUBRC will be
set to 8. The user can then replace the 8 with a 0 and continue with that
transaction.

This is granted by giving:
S_DEVELOP
Activity: 01/02
Object type: DEBUG

If you grant only display access for object DEBUG, then users will be able
to debug programs to analyze source code with production data. However,
users will not be able to replace values for objects such as SY-SUBRC. So,
in PRD, I grant activity 03 for S_DEVELOP for object type DEBUG. Most
importantly, this is secure and passes audit.

Hi,

this is an authority question. There is some authority necessary for /h. It
is strongly recommended NOT to give this authority at all the users.
Unfortunately I don't know what the correct setting is. Perhaps you create a
user with very little authority and then it shouldn't be allowed. Then you
could use SU53 in order to find out what authority is missing there.

This should be removed at any "normal" user in your system.

Regards

Volker
