Hi,
i need to add adobe form as attachement to user decision step in workflow.
1. i created activity step which call business object method with parameters workitem id
     i am using FM  SAP_WAPI_ATTACHMENT_ADD’  which will return attribute id
     i am passing that attribute with document id to 'ZSOFM'
        ZSOFM <-----------------------------------ZSOFM (Method to task)
      Bindings 'Attach_objects'  <------------- ZSOFM(Task to Workflow).
2. i created user decision step
    Bindings  'Attach_objects' --------------------> 'Attach_Objects'( Workflow to user decision task).
but when we execute first activity step in background i am not getting any PDF output .but when we  execute same method from class i can see pdf data is coming is it due to user name WF-Batch.
when i execute activity step in back ground which will have sy-uname as WF-Batch i am not getting any PDF output data.
please help how to solve .

In transaction SWO1 create a z-object lets say zmyobjpdf (you might want to use it as a sub object of your standard object without delegation since they will probably have the same key).
create a method in that object calling the adobe form.
set it as the default method in the object header.
now create an instance of the zmyobjpdf in the workflow for example as an attribute of the original object) and transfer it to the decision task.
It will be displayed as an attached object pressing it will call the default method - your adobe form.
If your question was about how to create a function module to display the form see SAP Library - PDF-Based Forms
