Partial shipments( and invoicing, too) may be done in one SO.
Look at the field Qty to Ship - it by default is equal to Qty, but you may change it (in your case to 75) and post the shipment. After this first posting, Navision will even update these fields accordingly, Qty remains 100, Qty Shipped = 75, Qty to Ship = 25.
The same applies to invoicing - you may invoice the part already shipped, or wait until complete Qty is shipped - that for is field Qty to Invoice.
I can’t imagine even theoreticaly, what else coud be - two different SO’s, one with partial shipments, one with two lines (subset of partial shipment) - what else? [:)]
Gete if you already knew these two solutions, then why didn’t you say that in your original post. You should say what you have tried already AND VERY VERY IMPORTANTLY explain exactly WHY you can’t use these solutions.
So… why can’t you use two lines? If you answer that maybe you can get some solutions.
