Services and material receipts must be posted via ML81N or MIGO during the period (month) the services were rendered or the parts were received, regardless if you have the invoice in hand.
- Excess receipts posted will be cleared up upon closing the PO.
- Estimate shortages can be adjusted upon receipt of the invoice.
Always ensure the vendor notes the Purchase Order number on the invoice prior to submitting it to SUMMA for payment.
