Hi Sudeep.
Yes BDT is available in CRM System.
Enter the transaction BUPA, BUPT.
You can do one thing, its all up to the logic how we design.
You dont need to append BP structures or tables for ADRC data.
Instead I would suggest, Go for BUPT Transaction and add a Screen at the end of all tabs, You will get the address fields there by doing a BDT.
Hope this helps.
