Answer 1

The tolerance keys compare only the invoiced quantity with the quantity delivered but not purchase order with the quantity of
the invoice.
If you expect a goods receipt but you have not receipt any goods yet there is no tolerance key which compares the quantity of the purchase order with the quantity of the invoice.
Example:
If you would post the invoice reference to the PO and with quantity = 100 (more than GR quantity) before posting others GR DOCs, but would the invoice blocked for payment and would release it using TXN MRBR after posting others GR DOCs (GR quantity = invoiced quantity), you can change the message type for M8 081 from 'E'(error) as 'W'(warning).
If you would post the invoice reference to the PO and with quantity = 100 (more than GR quantity) before posting others GR DOCs, but would the invoice not blocked for payment, you can de-activate the tolerance check of T-key 'DQ' via setting 'Do not check' as 'X'.
If you want not only GR quantity, but also the PO quantity, to be incl. in the tolerance check within MM-invoice process,please review the note 786810.
Look to SAP Note 786810
Reason and Prerequisites
The problem is due to the system design.
Solution
If you want the amounts and quantities for the purchase order items to be included in the tolerance check, you can use a customer enhancement (BADI) in the 'MRM_BADI_INVOICE_CHECK' function module to run the check on price and quantity variances based on the amounts and quantities from the purchase order item
