Purchase requisition events

[Hassine, Felix]

Everaldo,
 
Thanks for your response. It helps in that it confirms me that this is not
an easy task.
SAP has designed the whole thing to treat PR items, I have realized this
too. But
I thought it could be bypassed, since this is what our business users need.
A PR can contain
several items , and there is no desire to have them agreeing and commenting
5 or 10 times the
same request for compound orders.
 
I will  try to find my own logic to do this. But encapsulating ME51 is not
in the scope, because it
means creating some change in the standard, which is not in my plans.
 
Thanks again for your response.
 
Best regards,
 
        Felix
