============================================
Logon and Security - Connectivity - SAP Library
Callback Whitelist (only available for types 3 and T)
Using the callback whitelist you can allow callbacks from specified function modules. Select the checkboxWhiteliste active to activate the whitelist.NoteThe actual activity of the whitelist depends on the value set for profile parameterrfc/callback_security_method:
0: All whitelists are invalid, even the active ones.
1: Only active whitelists are valid
2: Only active whitelists are valid. However, also (invalid) inactive whitelists generate an entry in the security audit log if a callback is received from this destination that would have been rejected by the whitelist if active.
3: All whitelists are valid, even the inactive ones.
============================================
So you have to maintain the callback whitelist and set the parameter to 3 to get rid of the red traffic light
