Delete with ListDuplicate

Delete with ListDuplicate

  

Hello,

I have a question.

I created a list and the system automatically generated the code to delete only the selected records.

I reviewed the code and removed the duplication of the list.

Change actions to work directly on the original list.

I run the screen and it work.

Question:
What does the duplicate list?
Is it really necessary?


Thanks
