During the build/development phase in a development environment, sometimes it’s just easier to delete a concurrent program and start again.

However, this isn’t possible via the Concurrent Programs screen.

If you have DML access to the database, you can simply delete the concurrent program using a standard API in an anonymous PL/SQL block:

BEGIN
  fnd_program.delete_program
  (program_short_name  => 'XXAP004_INACTIVATE_SUPPLIERS'
  ,application         => 'XXAP'
  );
END;
