Please see the PurchaseOrderLine.Quantity Property of the PurchaseOrderLine class in the .NET API namespace Sage.Peachtree.API. Thanks!

The Quantity Property is just a decimal that has a set/get and the QuantityReceived just has a get of a decimal.

Setting the QuantityReceived is not yet implemented. You can submit an API enhancement request at the Ideas forum and vote it up with your colleagues and clients. Our product management team will then consider it for implementation. - https://www.sagecity.com/support_communities/sage50_accounting_us/i/sdk__api Thanks!

Thanks I'll submit it.  Do you know if there is a way to do it via the COM api?

There is no direct method in the COM API but there could be an indirect method using the import/export objects. I have to research it and review it with our developer team. This would require a subscription to our developer partner program.
