Sample Script to Copy Responsibilities of one user account to another user account using API

fnd_user_pkg.addresp is an Oracle standard API to add responsibilities to a user account.

Below is the script to copy responsibilities of user “INTG_USER” to “IMPL_USER” 

DECLARE

  --
  resp_count NUMBER := 0;
  --
  CURSOR src_user_resp_details
  IS
    SELECT DISTINCT fa.application_short_name,
      fr.responsibility_key                  ,
      fsg.security_group_key
       FROM fnd_application fa      ,
      fnd_responsibility fr         ,
      fnd_user fu                   ,
      fnd_user_resp_groups_all furga,
      fnd_security_groups fsg
      WHERE 1                               = 1
    AND fu.user_name                        = 'INTG_USER'

                 );
      --
      resp_count := resp_count + 1;
      --
