If it's appropriate, why not?

Just use the correct includes.

Better than writing old style FORMs anyway!
But I would consider creating a global class and using the FM just as a wrapper - if the FM is needed at all...

Hi Matthew

I thought instead of mixing both procedural & OOPS, it would be better to use one approach.

Thanks

Why didn't you search before asking, exactly the same question 10 years ago.

voorapoornima That would be better to indicate your thoughts in your initial question, to differentiate it from the exact same question asked and answered 10 years ago.

It is better to use local classes than forms.However, I always use a global class nowadays, as 549747a7e4a74d368295cb9cc2b08cc4 recommends.
