Thanks for extending the concept of Attributes from the Product information/Procurement module to HR module. 

It will really be good to have this functionality available for Master Data as well. Although D365 has come a long way with functionality we still need to go through development effort for simple custom fields that client want on master records at implementation stage. 

It will be really good to have an ATTRIBUTES fast tab, like in 'Product Configuration model' fast tab, which allows the definition of attributes for each of the master records. This will save a large amount of development during implementation where the client want a few additional fields added to the standard D365 fields  with the option of making them mandatory for selection. 

This can be started initially with say the CUSTOMER, VENDORS, PROJECT CONTRACTS and PROJECTS and then extended to Purchase Order and Sales Orders in the Future.
