I Have four table

I have a relation FK_Tbl_Order_Request_Tbl_CPU and FK_Tbl_Order_Request_Tbl_Monitor

when i try to enter data for moniter in Order_Request its giving me error

The INSERT statement conflicted with the FOREIGN KEY constraint "FK_Tbl_Order_Request_Tbl_CPU". The conflict occurred in database "EHealthInventory1", table "dbo.Tbl_CPU", column 'CPU_ID'.
The statement has been terminated.

You may be trying to insert a value for CPU_ID column in order_request for which no corresponding record exists in Tbl_CPU.

Please first insert record into Tbl_CPU and then insert record into Tbl_Order_Request.

First you have to insert in "Parent" table, then that Ids only will insert in "Child" tables...

@Savalia : i have data in CPU table , i have cpu id C-101 and so on , monitor ID M-101 and so on .. in the tables ..

i am trying to save ID's in Order_Request from different tables.

The error clearly states that there is a conflict with the foreign key constraint. It means you are trying to insert a value that does not exist in the Foreign Key table. In your case the value of "CPU_ID" you are inserting in the table does not exist in "dbo.Tbl_CPU". The foreign key values you insert in a table must exist in their referenced tables.
