Unable to change the password for fnd_user sysadmin.

Cause:

Signon Password policy is enabled in ERP application, so it will not allow to repeat the username in passwords.

Solution:

It should not contain the username in passwords. ie. sysadmin/sysadmin123

FNDCPASS apps/apps 0 Y system/manager USER sysadmin admin123
