One TO per Delivery ?

Hi,

Is it possible to restrict one TO per delivery document?

We have a situation where, we are running into issues wth multiple TO per delivery & we are unable to ship.

Eg:

Delivery : 10 EA

TO1 : created for 4 EA ( due to stock availability)

The TO gets confirmed.

TO2 : 6 EA ( gets created as stock comes in)

Still open & out for picking

When I goto PGI the order , it wont let me do it as its got open TO.

We operate in a huge WH, its v difficult to go and look for the other TO.

Ideally, it would be great if there is a setting for controlling the number of TO per delivery.

Any ideas?
