Hi Salman,
Question: what status is the ZMCR RFC in when the users can confirm it? I assume it is Implemented. If it is, you can change the configuration to only set the ZMCR RFC to Implemented when the related ZMHF Urgent Change is Completed (E0008) and not Production (E0006). Remove the entry as below:
Make sure that the above entry still exists for ZMHF status E0008. With this change, the ZMCR RFC will not be automatically changed to Implemented status until the related ZMHF is Completed instead of Imported To Production. Thus, the user shouldn't be able to confirm the RFC until the Urgent Change is closed.
Hope this helps and kindest regards,
Paul
