I’ve ran into this recently as well. I need to remove the line and re-add
it, otherwise it’s all messy. Pick list gets goofy, pack slip, invoice,
etc etc.
Our order entry people have issues doing that. A lot of times our orders are structured with lines referencing the lines that follow in the order.
If Line 3 was for the Sales Kit, related to line 1, deleting it and re-adding it makes it a new line at the end of the order.
And some customers get picky when the lines on the order are re-arranged, and no longer match with their PO.
What might work, is changing it to another SK P/N, and then changing it back. The SK part (the parent) retains its order lines. The SK’s component’s lines get deleted, and new ones added to the end of the order. But these still relate to the SK parent line number.
We have similar requirements for some of our customers. What we ended up doing was making a UD field for customer PO Line. Then we sort our reports based on the UD field instead of the sales order line.
That may not be an option for you as there’s quite a bit of work involved, but I thought I’d share.
If you change it to a part and then change it back, keep an eye on the components. We’ve had some wonky behavior doing that on 10.1.500.16.
