Hello Experts, 

Seeking a guidance for TMF 688 compliant events from Customer order management (COM) component (seperate from Ordering component which handles orchestration and decomposition) for showing order progress view for customers (different component from COM) -  

• Any TMF standard for orchestration and decomposition other than TMF622 being Ordering and COM are different components in the stack? 
• Placeholder at Product order item level to map decomposed Order Item(s) to corresponding product order item received in product order as to show Order progress view, this mapping is needed to relate notifications received from down streams and sent from COM to Order progress view system

Thanks, 

Pramila
