Impact of Detailed bill lines in Subscription maanagement on RMCS

Business use case:

We have fusion Sales order which have hardware lines along with Subscription lines. Hence Subscription Contract is created from order management integration once subscription lines are fulfilled in order management. Revenue Contract is created successfully from order management and when We tried to send Subscription version line to RMCS from Subscription management however we observed that these lines are getting rejected in VRM_SOURCE_DOC_LINES table and we can see error message as ''You must enter a unique composite key for the source document line'' through error correction spreadsheet.

However, on further analysis, we have found that whenever in Subscription Contract for a subscription product, there are multiple bill lines are there for single Bill period due to multiple Covered Asset, only for these scenario Lines are getting stuck in RMCS staging table and when for Single Bill line is there for a single bill period, lines are getting processed successfully in RMCS.
