Adding new Parameter in existing component for BPT process

In BPT process, never ever add any parameter with default data for any existing components. Because this might cause very bad effect on your other scenario what you are using presently. If you really want to add some parameter in your existing component then after adding the parameter delete the parameter value and save the component (i.e. save the component with new parameter with blank value). Always verify this should not cause any problem to the other scenario of your other test suite.

By mistake if you add the parameter with default value and save then delete the parameter field from your component and save. And again add the parameter with blank value and save.
