In configuration we have maintained that individual PR will be generated from Maintenance Orders. The Service PR has its Release Strategy. The requirement is that after the Service PR has been approved (based on Release Strategy), no further changes will be allowed in the same PR. For any changes, a new PR will be raised against a new Operation.
In standard system, even though the PR is released and we make changes in the quantity of the service in the Maintenance Order, the same is updated in the PR.
How can we restict the changes in Service PR from a Maintenance Order after it has been released?
