You have a requirement to add Product Location section but there is no possibilty to activate the product Location in the registered product.
Product Location section is part of Installed Base under Overview. Some of the fields under Product Location sections are Field and Area.
Registered Product is a combination of 2 BOs(InstallationPoint and PDM Individual Product). You have added 1 BO(PDM_INDIVIDUAL_PRODUCT), but you can't add and see the fields from IPOINT(/IBASE/INSTALL_POINT) Business object.
This is known issue and you can create separate entities and reach your objective.
Note: Multiple BOs cannot be merged in single BO
