Internal Order Maintenance

Hi to every body

I have just a simple question hope some can help me!

Even if in the Order Type Details (SPRO  CO  IO  ORDER MASTER DATA  Define Order Type) for a specific order type as object class there a specific value: INVST (investment), during the order creation (TCODE KO01) in the object class field is displayed a different object class value (instead of INVST is OCOST), we need to scroll the list in order to select the right object class.

Is it possible to have automatically the right object class?

Regards

Marco
