Hi Bart
I was curious to see if there was anything out there that could answer this question and I found another post which is similar. Let me quote: https://scn.sap.com/thread/1266144

Hi Silpa,
In the standard, this isn't possible with the BP. However, you can create a customer as a reference of another existing customer, and then sync this new customer into a new BP. So you can do this indirectly,.
If you want to create a BP directy as a reference of another BP - sorry, this isn't possible. You would need to copy the BP into another BP using a custom report. You can develop your report along these lines :
1. The easiest way is to use APIs. Start by calling BUPA_CENTRAL_GET_DETAIL usign the BP number. THis will give you all the central data for the BP - e.g. name, etc. Now, merely feed the output of this module into the module BUPA_CREATE_FROM_DATA. This will create a new BP with the same data of the old BP.
2. Now that the main BP is ready, you need to start copying the individual datasets - addresses, bank details, roles, Id, industry,etc. This is tricky - the ADD apis - BUPA_ADDRESS_ADD, BUPA_ROLE_ADD, etc can only create one record in a call. So, you need to first get the data of the reference BP using the GET_DETAIL api e.g. : BUPA_ADDRESS_GET_DETAIL, then loop at each returned record, and pass that into the corresponding ADD BAPI.
3. Be sure to call BAPI_TRANSACTION_COMMIT at the end to commit the data to the DB.
I hope this helps you.
Cheers,
Rishu."
