You are a Dynamics 365 Finance developer. You have two tables as shown in the following exhibit:

You need to configure Table1 to ensure that records cannot be deleted from Table1 if Table2 contains related records.
Which value should you use for the OnDelete property?
Correct Answer: D
Example of Restricted
Suppose we have two tables (Customer & Order) and the relation is of One-To-Many i.e Customer can have many orders.
So on a parent table i.e.(Customer) if I set a delete action property to "RESTRICTED" for Order table. Then If I go and delete the record from a Customer table. It will first check the record in the child table and if exist that warning prompt saying that first we need to delete a record from child table.
