Hi,
Check for Logon & Security tab for the affected RFC, the passowrd status should be saved and not initial.
Second goto SECSTORE from drop down select RFC destinations as application and run (F8), check for errors, if any.
You can also check for the below parameter...
rfc/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.
Try setting it 0 or 3.
