warehouse management sales order put location

Hi everyone 

I am having this problem with the put location 

if I had 1 item on the sales order it will put the final location in the wark 

and if I have multiple items it shows blank 

I set the location directive code in the work templet and the location directive 

if anyone has information about why the final put doesn't show in the work  if it is multiple item

Thank you for your attention
