Purchase requisition events

[Everaldo Biselli]

Hi Felix,
 
The SAP R/3 works with the purchase requisition item and not with the
purchase requisition. As far as I know, until release 40B, there was no
change document that was sensitive for purchase requisition events, it just
works for purchase requisition items. There was no user exits in the
transaction that create purchase requisitions (ME51) that can be used too.
In  my opinion, you should create a new Business Object that has  in the
key only the purchase requisition number, create a new event in this
object, and activate this event using the ABAP function module
SWE_EVENT_CREATE. But you should create too a new transaction that
encapsulates the standard transaction (ME51) and after calling this
transaction you will include the CODE for calling this event. That's in the
only solution that I can find.
As you can see this is a complex solution that includes ABAP development
and some experience constructing workflows. Maybe should be better review
the process and check if it's possible to change something to help you with
this problem.
 
Anyway, I hope that this information can help you.
 
If you need any further information, just let me know.
 
Everaldo.

Hi all,
 
        We need to create 1 workflow instance when a purchase requisition
is
created with the blocking flag on. Only 1 should be started, but the system
generates as many events as line items in the workflow. As a result, my
workflow may start several times, which is not the desired effect
 
I have tested the "overall" release button in the customizing (Purchase Req
release Strategy), but then no event al all is then generated.
I have also attempted to create a "change" doc for change document class
"BANF" , but it works only for CHANGED status, not for CREATE.
 
Has anybody experienced the same problem ?
 
Thanks for any clue.
