I have a forms approval process where I am doing round robin assignment with 4 users. I want to assure that the round robin is not assigned to the same user that did the previous approval.

For example, the 4 round robin users for level 3 approval are Joe, Kim, Sue, and Mike. Joe performed approval for level 2, so I want to exclude Joe from being included in the round robin assignment for level 3 approval. I do not want Joe to be able to perform both approvals. I have the approvers for each level in variables.

Is there a way by using the filter and variable to exclude the user (Joe) in the round-robin assignment.

Thanks in advance.
