Doubt in defination in LIV

Question

I am not able to understand the meaning of following statement:
invoice items with a small amount result in a relatively large quantity variance, and that invoice items with a large amount result in a small variance.
this line is from Quantity Variance
Quantity variance: For a purchase order, the open quantity to invoice is a result of the delivered quantity and the quantity already invoiced. There is a quantity variance if the invoice quantity does not match this open quantity. At the absolute upper limit, the quantity variance is evaluated on the basis of the amount in the invoice item. This means that invoice items
with a small amount result in a relatively large quantity variance, and that invoice items with a large amount result in a small variance. You can also define percentage limits for the quantity variance check, for which the system does not take account of the purchase order price.
please help

Answer 1

Hi,
Quantity variance is evaluated on the basis of the amount in the invoice item and your query can be explained with an example.
Assume that po price is 1  and invoice price is 1.50. As per evalluation the variance will be 50%.
Similary if po price is 1000 and invoice is 1050, the variance will be 5%.
Cheers !
