Attachment when starting a WF via WAPI

[Mike Pokraka]

G'Day,

Does anyone know if it's possible via SAP_WAPI to start a WF with
attachments?
SAP_WAPI_START_WORFKLOW doesn't allow anything in the _ATTACH_OBJECTS
container element.

And doing a SAP_WAPI_ATTACHMENT_ADD afterwards is not only ugly, it is
also unreliable if the workflow does a few background steps in the
beginning.

I can do it via the internals, so a plan B is not what I'm after; the
question is really about whether it's possible with WAPIs. (No events
either, it would mean a major reengineering of an existing WF).

Thanks & regards,
Mike
