Load runner primary foraign key relation issue while test with virtual users(50 or more)

Dear All,

I have record one process and LR automatically generate script.

My Current scenario is same like below.

Master Table: Table 1: Id, Name, Address, etc
Detail Table: Table 2: Id, Table1Id, Score, etc

When Load runner generates script then it will define fixed value in "Table1Id" column. So when I will execute Load Runner for 100 Users then it will store same Id in "Table1Id " column.

Actually when new entry start then
1) It will store new entry in "Table1" and return Id (This Id = Table1Id ("Table2"))
2) Store sub entries in "Table2"

Primary Key: "Table1" - Id
Foreign Key: "Table2" - Table1Id
Relation: One to Many
