EK00 - picking output

Hi,

I would like to activate the Picking Output EK00 in my deliveries, but whenever I go to Delivery -> Picking Output, the fields are all gray out ...

I read that for Non-Wm , the delivery can be automatically picked by printing this EK00 - picking output...

Any ideas?

*I already put EK00 in the shipping point picking output.

Thanks,
