Task to method binding not visible still wf is working

Hi Experts,

I am working on existing workflow where Task-method binding is missing.

Still this workflow is functioning correctly. Can any body guide me in absence of task to method binding how the data is getting passed from task container to method container and vise-a-versa?Secondly how to debug this method in SwO1 as method isnt having import export parameters but get-set macros in it?

Kindly guide.

Thanks,

SD
