User Password self service with security questions on ABAP stack

Hi ,

We have one requirement that to enable the SAP users to reset the password by themselves.

Currently we have only ABAP atack and there is no Java stack.Kindly let me know the possibility of achieving the user self passowrd reset on ABAP stack.

We donot have Identity Management integrated.So we can skip achieving this using Identity management.

Regards,

Ramesh
