STO not picked up in delivery VL10B

Hi,

I have created a Intercompany PO for which the shipping data was created correctly. But when i try to do a delivery using VL10B , the document is not picked up for delivery.

The problem is coming for the new document type which was created few days ago , there is no issue if i use the old document type. I remember somewhere we need to maintain the document type in delivery copy control , but could not recollect where exactly it is.

I checked with all the necessary configs , but could not get a break through. Any help would be highly appreciated.

Regards
