Transfer document text from one window to another window

When we are creating a customer order through a sales quotation, created document text(RMB Option) will be reflected in the Customer order. But when we enter a document text to a customer order where the supply code is “Purchase order Dir”, those entered document text will not reflect in the Purchase requisition or the purchase order. Is there any way to transfer document text from one window to another window when those windows have an interconnection such as “Purch order Dir”, “Purch order Trans”?
