MIRO invoice amount exceeding the blanket po overall limit

Question

Hello Gurus,
I'm having trouble with invoicing against a blanket purchase order. Can anyone please explain why and when does invoice amount can exceed the blanket po amount.As I understood from the SAP documentation I should not be able to invoice for amout greater than the overall limit on the blanket PO.
Here is what i did.
1. I have created a blanket PR for 1000$  (Purchase requisition document type - Frame work requisition , overall limit - 1000$ , No limit flag - unchecked)
2. I created a P.O ( Order type - Frame work order, validity start date - todays date , validity end date  - 1 year from today's date ).
3. I checked the tolerance limits in OMR6 - for the above company code , tolearance key (LA) , check limit is blank , for tolerance key (LD) the check limit is 100.
4. However I was able to invoice for more than 10,000$ against this Purchase order.
My question is , am i missing anything so as the invoice amount not to exceed the blanket po amoutn ?
My requirement is - MIRO invoice should not allow the user to post in invoice with amount exceeding the blanket p.o amout.
Why would the MIRO invoice not checking the blanket po overall limit ?
Appreciate your responses .
Thanks.

Hi Kirit,
For tolerance key type 'LA' (Amount of blanket purchase order) , upper limit I set the check limit val to blank , and for percentage , i checked the do not check flag.
For tolerance key type 'LD' , upper limit absolute check limit value is '100.00'.
Where do i set the status of message , infact I'm not getting any message while posting the invoice.
Appreciate your help.
Thanks
