I believe our previous test on SELECT SINGLE vs FOR ALL ENTRIES did not surprise many of you because I see a tendency towards FOR ALL ENTRIES in programs I encounter. In previous scenario, we were able to access the search table with primary key but this may not be the case every time. Let’s see what happens […]

Because obligatory parameters demand input on every action of user and interfere with user command logic, which results in a broken selection screen. Let’s see […]

This is so wrong. According to ABAP keyword documentation: If no exception is raised, a call sets sy-subrc to 0. So in the above example, sy-subrc will always be equal to […]
