Decomposition Rule Issue for Telco Service Order For Modify

[arpanshah]

Hi Folks,

I am facing decmosition issue while placing a Service Order for the Modify journey.

I have a service specification catalog Customer Facing Service (CFS) and Resource Facing Service (RFS). Both CFS and RFS having relationship with decomposition rule. 

This decomposition rule triggers successfully while I place a Provide/Cease Service Order for Telco. 

Issue: 
After completing the provide order, while I try to place a Modify Service Order for Telco, the decompostion is not triggering .

If I remove decomposition rule the CFS to RFS decompostion is happening. 

This is a strange behaviour because same Decomposition rule is not working for Modify journey only.

Hi @arpanshah 

As part of the Modify use case, the change that you are making.. is that affecting the decomposition rule? That is, are you changing a characteristic that you have used in the decomp rule or is that change unrelated to the rule?

Can you provide more details?

The change I have is not related to the Characteristics I use for the decomposition.

Refer to this article that explains how the Change Order is processed in Order Management.

In your scenario, since the change being made is unrelated to the decomp, the application is not further decomposing as it may invoke orchestration flows not related to the change.

@ShashankInamdar Thanks for the explanation in your DYK. It is an excellent explanation.
Now, I understood the problem. I don't have changes in the characteristic which is associated with the decomposition rule, therefore the decomposition is not triggering. 

Still I want to decompose based on my existing rule. Is there any way we can override this OOB functionality? Because in my catalog design the CFS have 4 RFS which decompose based on decomposition rule only and if it don't work my functionality will not work.
