Suggestions:
Users should ensure that the bank selected in the automatic payment process is mapped with the users site and login site. Users have to go to the site bank master, its menu exists in the Finance module -> Finance setting -> bank related and search for the user site. Users can add a record for the login site by selecting that particular bank code and maximum limit.It was bug in system later on rectified
