Back to Back Order Amendment Issue RELATED TO pURCHASE oRDER

Hi All,

I am implementing Back to Back Order for my client. I want to know that at some point after Sales Order booking and sucessful Requisition Import, my client want to do some amendments/cancellations in the Sales Order. So how the same can be notified to the Purchase department and can the same Purchase Order can be modified accordingly.

Thanks and Regards,

Rohit
