A) Current behavior in vanilla / customer environment

1) when FTI is created then system will default the address from the customer master
2) when a new customer is updated in the same FTI then the new customer address will override the existing FTI address
3) When a new customer is updated in the same FTI and this new customer is not having address then the existing address in FTI header is retained

B) Customer expectation

1) when FTI is created then system will default the address from the customer master
2) when a new customer is updated in the same FTI then the new customer address will override the existing FTI address
3) When a new customer is updated in the same FTI and this new customer is not having address then the existing address in FTI header should not be retained.
Every time the customer is changed in the FTI header system should remove the existing address and bring the new address from the new customer updated in FTI header and if this new customer is not having any address in customer master then FTI header should have blank address
