3115185 - Cannot Request P system after Q system upgrade


When clicking on 'Request P System' button after Q system upgrade, below error occurs:

"Could not request system. Please contact SAP."

Reproducing the Issue

  1. Access CBC system - Project Experience.
  2. Go to 'Systems' tab.
  3. Click 'Request P system'.


If you have missed requesting the P-System prior to the Q-System scheduled upgrade downtime, then you will only be able to request it after the P-System scheduled upgrade downtime.

The Q-System will be upgraded first. Then, two weeks later, the P-System will be upgraded. During the time between the Q and P upgrades, regression testing occurs. 

If the P-System has not been provisioned immediately after the Q-System activation, it must be requested at least 7 days prior to the Q-system upgrade so that both the P and Q-systems are on the same base release. We strongly recommend requesting the Q-System as early as possible before the scheduled Q-System upgrade downtime, to avoid any project delays.
