Yeah, intially I thought attachment is getting deleted, apparently it's not giving read access on that attachment to users since acl condition is based on table name, as mentioend.

@Kiran Maruthi 

Does it have admin overrides checkbox uncheck?

Even for admin the variable is not seen?

If my response helped please mark it correct and close the thread so that it benefits future readers.

@Ankur Bawiskar - Yes it is not admin overriden, they have given this bcus legal space is more secure may be.

@Kiran Maruthi 

that could be 1 reason.

Ideally only the correct role user should have read access to that document.

You can discuss this with your customer and based on that either deactivate that OOB acl or raise a HI ticket.

Hi @Kiran Maruthi 

You can go for own ACL but before that make sure it has not impact on other part.
