Hi Exprts,

I have created a task.In that task called class and method.Method has import parameter I_import and export parameter o_export.

When i clicked on binding only binding for I_IMPORT is visible.

I wish to get output from the method.

Kindly guide how  screen for o/b binding below i/b binding will be visible?

Thnaks,
