In Business Central, on Sales Quote you get Your Reference, why is this not External Document No.? External Document No. is used on Sales Order, Sales Invoice and Posted Sales Invoice. The Your Reference field is carried through all the "stages" but only on Sales Quote are you given (without modification) Your Reference.
Any rationale for this?
What is the distinction between Your Reference and External Document No.? Why have both?
External Document No. specifies the number that the customer uses in their own system to refer to this sales document. You can fill this field to use it later to search for sales lines using the customer's order number.
Your Reference is quite often the same, it’s a reference for the customer.
