How PO validity start and validity end works

Question

In the PO Header (tab Additional data), there are fields: validity start and validity end.  The help text states the following:
Start of validity period
Date as of which services can be performed or materials delivered.
In the case of purchase orders:
Start of the period in which the service is to be performed or thematerial delivered.
End of validity period
Date up to which services can be performed or materials delivered.
In the case of POs:
End of the period in which the service is to be performed or thematerial delivered.
I maintained a validity date range 01/01/2007 to 01/10/2007.  When i tried to receive the item with posting date 01/15/2007, the system saved the GR without even a warning message that the GR was outside the PO validity date.
How does this field work?  Is this standard configuration or does this only work with a user-exit?
I would appreciate any input.
Regards,
Dominique

hi ,
use transaction OMCQ,
set the status of message for M7 163 to error. if this message is not present in the list , then go to new entries and select  this message and enter it into the list
after this set the status to "E".
