Billing plan status for WBS is being copied to the new Project

Hello SAP Experts!

We are currently encountering an issue when an existing Project is being copied for a new one in CJ20n, the Billing plan status is also being copied into the new Project.

We do intend to copy the Billing plan line items, but we do not understand why the status is also being copied. If a billing plan was completed in a previous Project, that completion status should not be copied into the newly created Project right?

Please note that the Billing plan status is not being populated as SAP standard behavior, there is a third party system that handles the invoicing and once a document for a specific Billing plan line item is received, the Billing plan status is updated to 'C' to lock that Billing plan line item.

Is there a way to prevent the system from copying the data in FPLT-FKSAF when using the copy project functionality in CJ20n? Tinkering with the checkbox under Template during copying of the project did not influence the Billing plans.

Thanks and regards,

Ramon
