How to make PO for an item which is dependent of concentration of liquid?
We purchase chemical from supplier in liters with agreed concentration. The PO is generated for X liters to supplier. On receipt supplier also informs us the concentration of that chemical, which is normally less then the agreed concentration. GRR is made for the litres of chemical received only.
Invoice received from supplier is adjusted as per concentration. Finance team is unable to make payment as the amount shows is against GRR is different than invoice.
Can anyone advise how we can incorporate concentration in order which can help us in making correct payment?
Thanks
