Hi Sunitha,

<i>RFC_ERROR_LOGON_FAILURE </i> is coming directly from R/3. Try to login directly to R/3, there u will get the message "Password logon no longer possible- Too many failed attempts". Reset the password, this will work...

Hi

Sunitha,

This is an error due to passorwd getting locked

[Former Member]

Sunitha,

your backend SAP user id got locked due to too many failed attempts. Ask your basis or security admin to unlock the user id you are using and reset the password. Please note - SAP has a security mechanism which locks a userid if you try with a wrong password for more than a certain number of times (3 most likely)
