1. Change Dealer table defination and set IDENTITY(1,1) to DealerID
2. Insert Into Dealer (DealerName, DealerMPA) Select DealerName, DealerMPA From Test

all should be good.

Is Dealer completely empty? - doesn't really matter
Is DealerID an identity column? - assume no

insert into Dealer
select row_number() over (order by DealerName), DealerName, DealerMPA
from Test

Is Dealer completely empty? - NO. Okay try not to clash with existing PK
Is DealerID an identity column? - assume no

insert into Dealer
select isnull((select max(DealerID) from Dealer),0) + row_number() over (order by DealerName), DealerName, DealerMPA
from Test

since dealerid is a primary key we cannot insert it directly. so that we can do a small workaround assuming that I am adding 7 with delaermpa and using it as dealer Id. This is just to give idea for our situation.Please note that the fieldname in Test table is delaermpa. if it is correct then proceed or else change the fieldname in the below given query

insert into dealer  select '7'+left(delaermpa,1) as dealerid, * from  test
