Yes, it is true that you can create a Lookup Relationship to link an object with itself in Salesforce.

This type of relationship is called a self-lookup relationship, and it is used to create hierarchical relationships between records of the same object.

For example, suppose you have a custom object called "Employee" that represents employees in your organization. You may want to create a self-lookup relationship called "Manager" to link each employee record with the record of their manager. This way, you can create a hierarchy of employees and managers within your organization.

To create a self-lookup relationship, you will need to create a new custom field on the object and set the data type to "Lookup Relationship." Then, select the same object as the target of the lookup and choose the appropriate field labels and options.

It is worth noting that self-lookup relationships have some limitations and considerations, such as how to handle circular references and how to maintain data consistency. Therefore, it is important to carefully plan and design your data model before creating such relationships.
