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;
