Hello Kaitlin,
it appears that either your business processes are very different to what I have encountered so far, or I have misunderstood you completely.
What is the benefit of using different material codes between the quotation and the order?
My understanding of a quotation is that you answer a customer inquiry on the possibility to produce/deliver a certain product with specific properties and specify the price and date range.
The customer agrees to order it from you, but then you decide to change the agreement and deliver something different.
Is this really a good business practice?
If there are different variants of a product available for ordering, I, as a customer, would expect to see them listed as alternatives, so that I can choose which one suits me best.
Another possible reason I can think of, is that you don't wish to give out some information on the exact product properties when you send the quotation to the customer and now you need somehow to determine the article codes for internal use...
Can you please elaborate?
