'Print price' condition control of PO

Hi Friends,

I have dveloped new document type for the purchase order. I have created PO with this new doc type here in condition control tab ' Print Price' is getting by default tick. If I use document type NB with same other data then ' Print Price' is by default unticked.  I want to make this ' Print Price' untick for the new document type. How can I do this.

Thanks,

Kiran
