When I extract the EBOM from CATIA to excel, I get a column called "identifier", which reflect the depth level and each part location within the EBOM. 

Each EBOM line gets a unique identifier. 

Example:

However, when I export the MBOM using PPR spreadsheet, I only get the level column, but not the identifier.

Is there a way to export the MBOM to excel with the "identifier" column?

Thanks in advance!
