Debug middleware flow from R3 to CRM

hi experts,

does anyone know how to debug middleware flow from R3 to CRM?

i am creating an order in crm which is getting replicated to r3 but when i change it in R3 it is not coming to CRM instead the status of the order in crm becomes 'B to be distributed'.

i have implemented X scenario and that is working for other type of orders.

please give me suggestions. its very urgent.

Thanks in advance,

Sagar.
