Summary :
The SAP Note addresses error messages related to RFC connection issues with SAP back end systems, particularly targeting the SAP-OSS destination. Essential errors include "Name or password is incorrect" and "Destination blocked: too many failed connections due to wrong user/password." The note identifies user authentication errors, either from incorrect credentials or password changes not yet synchronized across SAP's backend. Solutions suggested include verifying credentials with the SAP Support Portal, adjusting logon data for SAP-OSS directly via SM59, and ensuring system alignments after password updates. Transaction SM59 is emphasized for testing and adjusting RFC destinations to resolve connection and authorization issues.
