This error message "00024error during logon" is thrown as a consequence of another error, which can be discovered once the steps in Solution are performed.

The problem itself is not the ''00024error during logon" message, but the fact that the message is masking the actual logon and trusted return codes.

To understand why the RFC destination is not working and correct it, it is necessary to check these return codes. However, fixing the "00024 error during logon" message should be prioritized.

The way to do it is: changing the parameter 'login/quiet_mode' value from 1 to 0 in the target system. This is not a dynamic parameter, system restart is required.

After changing the parameter, instead of "00024error during login" a message with logon and trusted return codes will be returned. The meaning and solution of these return codes is documented in the notes below:
