Workflow Attachment on System-Overlapping possible ?

[Seiz, Gert]

Hy there,
we have a scenario for start a workflow on system A and create an attachment
in backround for binding to the Workflow.
After this step an other workflow should start on stytem B via
SWU_START_WORKFLOW e.g.
On this workflow it should be also possible to have access to the attachment
on the system B.
But you can fill the parameter ATTACHMENT_LIST only with an ID . So you have
a reference and not a copy of the attachment.
So you doesn't have the ID on the second System.
Does anybody has experience with this ?
System A 4.5B
System B 4.6C
