Workflow shouldn't start when directly posting an invoice

[Loeffen Robert]

Hi Workflowers,
 
I have the following problem:
 
I build a workflow for incoming invoice processing. The starting event =
is Invoice.CREATED.
But when i directly post an invoice with transaction MIRO. I don't want =
the workflow to be started but
it starts. (the event Invoice.CREATED is raised when posting the =
invoice)
 
I have a wait for event step in my workflow, waiting for the event =
Invoice.POSTED connected to the end of the workflow.
But still the workflow continues in another branch of the workflow.
 
Does anybody have any idea how to solve this.
 
Gr. Robert
