How to use the Copy mapper to copy Bill lines from one Subscription to another during duplication

Summary:

Hello Oracle Experts!

Our requirement is to transfer the billing lines from one Subscription to another while duplicating a Subscription. We found that copy mapper can be used to achieve this, but unfortunately, we are facing an error while duplicating a subscription though all the required setups are in place.

We mapped all the required fields in Copy Mapper but still got the below error message.

Error message:

We tried to map the Recurring Flag attribute, but that was not available in the Bill Lines attribute (Attribute Mappings), if anybody has a solution for this, please let us know.
