Listing the SAP standard programs that have been modified
I want to make a list of the SAP standard programs that have been modified. And since a modification of a SAP standard program requires an access key there must be information within the SAP systems as to which programs have been modified. But where is that information and/or how can I make a list of these objects ??
I have been looking into tables like TRDIR, TADIR and PROGDIR but didn't succeed in getting the required list of programs.
