I have an object called SalesInvoiceLine which maps to a table called SalesInvoiceLines. Before I save the object I want to know if the quantity field has changed in order to know if I have to update the inventory and by how much. How do I see the previous value of the row?

Good question.  This should do it:

originalValue = lineItem.EntityAspect.GetValue(SalesInvoiceLine.PropertyMetadata.Quantity, EntityVersion.Original);
