MRBR release invoices automatically quantity variance

Question

For a purchase order item there are several good receipts
and several invoices. Although the quantity of the goods receipt is smaller than the quantity invoiced, the quantity of goods received is bigger than the first invoice. So the first invoice should be released automatically. However no invoice is released!
Is this how SAP works standard, or can I customize this somewhere?
Example:
quantity received: 100 + 100 = 200
quantity invoiced:
invoice 1:   100
invoice 2:   200
total    :   300

Answer 1

Hello,
The GR-based IV flag is not on for the item. Thank you for your answer, but is does not help me.
I believe there is no solution for this problem.
This is the way how SAP works. At the moment an invoice is posted the systems checks the quantity invoiced and received (and other checks). If something is wrong the invoice gets a block at that moment. Later with the automatically release of invoices the systems checks if the quantity variance still exists.
With tolerance limit DQ the system checks for all invoices with a block if the total quantity invoiced is less or equal to the total quantity received. So the system does not check only the quantity of the invoice with a block.
If you change the limit of tolerance limit DQ to 5000 euro to many invoices will be released, also invoices that should keep a block.
For example:
quantity received: 3
quantity invoiced: 3+3= 6.(both invoices had a block, because DQ absolute limit was zero).
After raising the  limit to 5000 euro, both invoices were  released, which is wrong!
It is logical that DQ should have a low limit. SAP only tries to relase the invoices with block. There also can be invoices without block.
For example:
quantity received: 3 - 3 + 3 = 3
quantity invoiced: 3 (block)
          +3 (no block)= 6.
The invoice with block should not be released. SAP only knows this when SAP does a check of the total quantity invoiced and received.
