    The error you are facing is caused because the authentication for allowing RFC_PING is not configured correctly.

    ABAP system administrator can configure the system which will enable the authentication for the function module RFC_PING. Therefore please use the transaction RZ11 in order to change the Profile Parameter “auth/rfc_authority_check”.

    Bellow are the following parameters with description which will help executing the RFC authorization check:

    • 0 = No authorization check
    • 1 = Authorization check active (no check for same user) (no check for same user context and SRFC-FUGR)
    • 2 = Authorization check active (no check for SRFC-FUGR)
    • 3 = Logon required for all function modules except RFC_PING and RFC_SYSTEM_INFO (no authorization check) (*)
    • 4 = Authorization check required for all function modules except RFC_PING and RFC_SYSTEM_INFO (*)
    • 5 = Logon required for all function modules except RFC_PING (no authorization check) (*)
    • 6 = Authorization check required for all function modules except RFC_PING (*)
    • 8 = Logon required for all function modules (no authorization check) (*)
    • 9 = Authorization check active (SRFC-FUGR also checked)(*): Valid only with SAP Kernel 720

    Note: For kernel releases greater than or equal 720 PL 416, the best setting of "auth/rfc_authority_check" is "6" - only RFC_PING works without logon/authoritiy check. The right value of "auth/rfc_authority_check" in case of kernel release smaller than 720 PL 416 is "1". It means that all function modules of function group SRFC can be called without logon. Therefore for better security we recommended to update to kernel release 720 PL500 or higher.
