Customer PO field?

What field does Navision use to put customer Purchase Order Numbers into the Sales Order, generally speaking. Is it: External Document No. Your Reference No. Customer Order No. Thanks

We use the External Document No.

External document number can be used, it is good to keep Your Reference available for some other need, e.g. they may ask you to put on the tax invoice the code they use for you in there system, this could be be placed in Your Reference. Cheers Peter

Thanks for the feedback!
