How to identify if Subscription lines have been processed to RMCS

Summary:

Hello Team,
Could you please help us with the below ask.

Background: We have enabled the Integration between Order Management and Subscription Management.

Scenario: Sales Order is created / processed and pushed to RMCS. A contract X is created with the lines of version1.
Post Sales Order fulfillment, all eligible lines are processed to OSMC and corresponding subscriptions are created. These are then pushed to RMCS, which create an updated version of the original OM lines on the same contract X.

Ask: We need to develop a report that displays the Order Number, corresponding Subscription Number, corresponding RMCS Contract and if the related subscription lines have been pushed to RMCS or not. We would like to know is there a way to identify if the related OSMC lines have been pushed to RMCS, as we see that even the OSMC lines contain the document type code of FUSION_DOO in the above scenario.
