Passing Data from a screen to WF & back again

[Odedra, Menand]

Hi Guys / Gals
 
Has anyone got any ideas on how to pass data from an SAP Dialog screen to a
workflow and back again.
 
The screen is being called via an Object.Method
Does the following line imply that the container is being updated
automatically or do I have to pass data to the container?
BEGIN_METHOD ZCREATE CHANGING CONTAINER.
  SET PARAMETER ID 'MAT' FIELD OBJECT-KEY-MATNR.
  CALL TRANSACTION 'ZAL10' AND SKIP FIRST SCREEN.
END_METHOD.
 
Any help would be much appreciated.
Thanks
 
Regards
