Sorting Operations in Routing

I would have expected NAV to sort operation NUMBER in numerical order.

It sorts in Alpha numeric ! 10, 100, 20, 30 etc.

Can anyone tell me how to fix this (without having to go 0010, 0020, 0030 etc.)

Thanks

this is because the datatype of field Operation No. is Code…

I have never known a manufacturing Production order with ops that go 10, 100, 110, 20, 30…

Surely someone else must have noticed this? Is there a way to order the ‘Code’ field numerically instead?
