Problem with an extended business object

Dear experts,

I am extending a standard business object for sales BUS2032, with the name ZBUS2032. To the new bus ( ZBUS2032 ) I have added a new method by assigning a custom function module developed by me for a requirement. I have released the method it is fine and I am able to use this newly created method in my work flow. But when I added an another method to this object its not getting reflected when I tried to use it my work floe ( Not in the available method options for the object ZBUS2032 ).

Please help me in this front.

Regards,

Murthy.
