Wait step needs a diff obj type than th eobj type used to trigger the workflow

[Cristiana D'Agosto]

G'day all,
 
I am sure that what I need to do can be done, please help!!
 
version 4.6c
 
Developing a workflow that will be triggered when an invoice is parked in
the system (FIPP.CREATED); the invoice is actually scanned and the idoc
created the parked document and FIPP.CREATED is published. So far, so
good, no worries at all.
 
I then have a Wait step that is waiting for the scanned image to be
assigned to the invoice, then my workflow will continue. IXOS delivered an
object type (ZIRXDOFIIM) that has the same key as FIPP, and IXOS will
publish the event ZIRXDOFIIM.ImageArchivedAndAssigned when the image has
been assigned.
 
How do I make my workflow 'listen' to ZIRXDOFIIM.ImageArchivedAndAssigned?
I mean, the workflow is 'waiting' for that but how to 'bring' the object
type ZIRXDOFIIM to my workflow so the Wait step will work? Linkage table
and FM only to pass the object type to the workflow container?
 
Many thanks and regards
 
Cristiana
