Possibility of a workflow in 4.6c

[Kane, Rajiv]

Hi!
Is it possible to create a workflow for the following scenario?:
 
When maintenance have a work order but require a spare which is not in
stock, the planners put the W/O on hold WOM (waiting on materials)
purchasing buys the part. When the warehouse goods receiving enters the
arrival of the part in SAP does SAP automatically link (or can it be
configured to) and inform the planners that the part has arrived via the =
W/O
linked number???
 
Thanks,
