Sometimes you may come across a requirement where the logon procedure for an ICF service in an AS ABAP system needs to be adjusted. Maybe you need to remove certain logon methods, change the order, or allow all of them.
In this situation, it is better not to touch the original service directly. The safer way is to create an External Alias with the same name and setup as the target service, and then make the changes there. That way, the original service stays unchanged.
Go to SICF, select your service, and click Edit. Then, open the Logon Data tab to make your changes. In Procedure, choose the option Alternative Logon Procedure.
To select the Use All Logon Procedures
Check the Use All Logon Procedures checkbox. Then click Save to apply the changes.
To change the Logon Procedure List order
Under Logon Procedures List (in order of execution), adjust the number (No.) in the handler order as needed. If you want a specific logon procedure to be first in the list, set its number (No.) to 0.
Then click Save to apply the changes.
To remove specific Logon Procedures
Under Logon Procedures List (in order of execution), find and remove the logon procedure as needed. Click Save to apply the changes.
