How to find which custom program uses authorization checks

Hi all,

I have been asked to find out which custom ABAP program in our organization is using Authorizations checks and which is not.

Since there are thousands of custom programs I will need to automatize this process somehow. But I am not an ABAP expert and I will need some help.

Could any of you give me an idea of what would be the best strategy to find out if authorization objects/checks exist in a number of ABAP programs? (would a simple text search do?).

Many thanks,

Aldo
