How to access transaction without authorization

Hi,
Today I want to show you how to access transaction without authorization. One big requirement to do this trick is having to debug and replace function. Let’s start!

  1. I prepared myself user without authorization to the db02 transaction. When I want to run this transaction, I get a message: „You are not authorized to use transaction”
  2. Go to the SE37 transaction, and display function module: AUTH_CHECK_TCODE.
  3. Now seat a breakpoint on line 28, when sy-subrc is checked.
  4. Double click on sy-subrc value, and change it to 0.
  5. Press F8, to continue the program. Now transaction should start normally.
