1. POST-QUERY of the block
2. WHEN-VALIDATE-ITEM of rate and quantity

In each trigger you check whether the item should be enabled or disabled or update_allowed true/false. Key-nextitem is not a good idea.

you mean "update_allowed". Can you explain this:

I haven't got the slightest clue what you are trying to say here. Look at the Set_Item_Instance_Property built-in to set properties at record level.
