Changing the membership of an approver group does not affect requests that are already pending approval. When CentraSite submits a request to the approval engine, it assigns the users from the specified approver group to that request. The request retains its assigned set of approvers throughout the entire approval process.

For example, let's say that approval policy P1 uses approver group AG1, and that AG1 contains users A and B. If a user submits a request that triggers P1, users A and B will become the designated approvers for that request. Let's say that while this request is waiting for approval, an administrator modifies group AG1 and replaces users A and B with users X and Y. This change will have no effect on the request that is awaiting approval. Users A and B will continue to its designated approvers. The changes to group AG1 will only affect new requests that policy P1 submits for approval.
