SAP_WAPI_START_WORKFLOW

[de Valensart Schoenmaeckers, Patrick]

Hi fellow workflowers.
 
I am trying to start a workflow directly from a report using
SAP_WAPI_START_WORKFLOW. Now my problem is: how can I pass an object
instance trough the table INPUT_CONTAINER of that function module interface?
- Pass the object key (e.g. pass a project number for a workflow container
element defined by BUS2001001)?
- Instantiate the object with macro swc_create_object, get its key using
swc_get_object_key, and pass that key?
 
None of these two worked. Any other suggestion?
 
Thanks in advance for your help.
 
Kind regards,
Patrick de Valensart
