Purchase Requisition release cancelled allowing to change PR quantity
My purchase requisition release strategy is having two release codes with two different levels of approval. Once two approvals release the requisition then only system is proceeding to further level and after that it doesn't allow to change quantity unless it is not revoked. In the same way when first approving authority cancel the requisition then the system is allowing the user to change quantity even though the other level is still pending to cancel. Please suggest how to block the same and don't allow the user to change quantity until all levels are not yet cancelled.
Release pre-requisites are configured according to requirement for three levels and maintained a new release indicator as suggested not allowing users to change quantity till completely released or rejected by all approving authorities.
