How to modify Family table Object without Checkout and Check-In.

I am using Creo Parametric Release 4.0 and DatecodeM030

I have written utility for the Windchill- Creo Interaction.

In between for some CAD objects having Generic is Yes or Instance is Yes. For those objects, Utility is giving some exception.

So, I want to run my utility without Checkout and Check-In.

Any API help please.

Writing Utility behind is, I am moving one of the Attribute values to another attribute. Some migration issue, hence written it.
