In my project scenario, quotation is created in CRM and replicated in ECC. Sales order creation and rest other logistic operations happen in ECC. When sales order is delivered and invoiced ECC system assign system status to sales order as "Completed" which then flows back to CRM. Sales order no. and its status can be seen in quotation in CRM.
There are two sales orders in scope. One of sales order status is getting replicated from ECC to CRM correctly but not for other. Please let me know if I am missing some step for this sales order transaction type either in ECC or CRM.
