Hello,
I utilize Drop Shipment SO / POs. There have been several occasions where after I post the Sales Order the Purchase Order states "The Sales Line does not exist."
However, The Sales order does exist and is now in a Posted Sales Invoice section. Not sure what is causing the issue - it seems to happen quite randomly.
Anyway I can solve this issue on my own?
I am not seeing anything reported on this specific issue. Have you taken a look at the tables and compare the tables from a working document vs. one that is getting the error? I am thinking you might see a difference when you compare and could lead you to what is causing the issue.
