How to get the order or receipt reference on the invoice home screen?

Suggestion :
1.Using process trail links on a Side Panel (smart grid) ,the order,dispatch and receipt reference details are available.

2.In vision every transaction has the process trail option wherein the related transactions reference can check.
3.In the Process trail window,the reference transaction has all the options like view ,cancel,copy transaction etc which are available on normal transaction home screen.
E.g in case of invoice INV0001 having the sale order reference SO0001.On clicking the sale order,the system shows the options view,copy transaction,audit trail,Comments,Attachments etc.

4.Menu:

Home screen>>Transaction (e.g.Invoice)>> Search Scope>>Side Panel list>>Process Trail.
