changing PCR (Rule) getting error "You only have display authorization"

Reproducing the Issue

1. Open transaction PE02,
2. Change the SAP Standard rule like IN44, IN54, INTT, IN72, INF1 etc
3. The system presents the error: 

You only have display authorization:

Message No. P0406
Diagnosis
The object you are trying to change has been locked so that only the person responsible for it is authorized to make changes.
If you look at the object's attributes, you will see that the field 'Changes only by person responsible' has been flagged.
You can, however, display the object and the system has therefore switched to the display mode.

The error is presented even if you have SAP_ALL authorization

Resolution

The issue occurs because the SAP Standard rule like IN44, IN54, INTT, IN72, INF1 etc was created by SAP. This kind of message is included in the system to avoid undesired changes or to avoid changes not recommended by SAP.

However, In this case you can run the RPUCTF00 report to remove the lock and implement the manual steps normally.

1. Run the RPUCTF00 report.
2. In the field "Schemas" enter the IN72 rule(example).
3. Remove the checkbox "Set editor lock".
4. Set the OFF value in the "Test" field, so that the report does not go into simulation.
5. Execute the report, this will remove the lock.
6. After making the changes in the rule, lock the rule again by executing the report again. This time, check the checkbox 'Set Editor Lock' and rest parameters as explained above. This would lock the rule again.
