Transportation problem for Task

Hi Friends,

I am facing a transportation problem.

I am inserting new task in my existing workflow. For that purpose i implemented a NEW Method in Existing BOR and i created new task and added to workflow. Everything working fine in development.

When i transported it in to Quality inside the TASK NO BINDING SHOWING (No binding icon). When i opened the task system giving this message Method 'UPDATE_ZSWF016' is not defined for object type 'BUS2089' .

I am using 4.5 Version. Can any body help.

In Development workflow working fine. I am able to update the table.
