Create Many to one relationship with Adding lookup in CRM entity(Account / Contract)

Create new lookup attribute

While most types of new attributes are created in the Attributes area of an entity, lookup attributes are created automatically when you create a relationship between two entities.

There are two types of relationships you can create: many-to-one and one-to-many. Because many accounts can be associated with one Contract, you’ll create a many-to-one relationship from the Account entity to the Contract entity. This is the most commonly used relationship type for a lookup because typically any number of records in the entity to which you are adding the lookup can be associated with one record in the custom entity.

1.In Microsoft CRM Dynamics CRM , click Settings, click Customization, click Customize Entities, double-click Account, and then click Relationships.

2.On the Actions toolbar, click New Many-to-1 Relationship.

3.In the Relationship: New dialog box, in the Primary Entity box, select Contract.

4.In the Display Name box, type Contract. Though this is the display name for the relationship, it is also the display name of the new lookup attribute. The Type field is set to lookup.

5.If you want this attribute to be Business Required or Recommended, select the appropriate setting in the Requirement Level box.

6.In the Relationship Behavior section, in the Type of Behavior box, select Referential.

7.Click Save and Close. This leaves the Entity: Account form open. Keep this form open, because you will use it in the next procedure.
