The Microsoft Power Platform Functional Consultant certification, specifically the PL-200 exam, requires in-depth knowledge of data modeling, including the configuration of table relationship behaviors and cascading rules. In this article, we’re going to explore how to effectively set up these relationships and cascading rules, potentially simplifying your data management processes and aligning with specific business needs.
Understanding Table Relationship Behaviors
Table relationship behaviors determine how different objects or tables, like accounts, contacts, or leads, interact with each other in the system. With Microsoft Dataverse, you can establish various types of relationships, including:
- One to many (1:N)
- Many to one (N:1)
- Many to many (N:N)
Once these relationships are set, you define how actions taken on the primary table (the ‘1’ in a 1:N relationship, for example) affect related tables.
Cascading Rules in Table Relationship Behaviors
Cascading behavior is a set of rules defining how actions on the primary table affect related objects. The key actions include:
- Create: Happens when a new related record is created.
- Assign: Happens when the ownership of the primary record changes.
- Delete: Happens when the primary record is deleted.
- Share: If the primary record is shared with another user or team.
- Unshare: If sharing the primary record with another user or team is canceled.
- Reparent: Occurs when the parent record for a primary record changes.
- Merge: Happens when the primary record is merged with another record.
The cascade types for each of these actions include:
- Cascade All: All the corresponding activities are also applied to the related records.
- Cascade Active: Similar to ‘Cascade All,’ but only active records are affected.
- Cascade User-owned: Only related records owned by the same user are affected.
- Cascade None: No effect on related records.
- Remove Link: The relationship with the related records is deleted, but the records themselves remain unaffected.
- Restrict: Prevents the primary operation if there are related records present.
Here is a simplified example of how cascading rules work. Let’s say you have set a cascading rule for ‘Delete’ action as ‘Cascade All’. Now, when a primary record is deleted, all its related records will also be deleted.
Setting Up Table Relationship Behaviors and Cascading Rules
To set up table relationship behaviors and cascading rules, follow these steps in the Power Apps portal:
- Navigate to Data > Tables.
- Choose the desired table and then click on the Relationships tab.
- Click on the relationship you want to modify.
- In the ‘Behaviour’ section, you can select the desired cascade rule for each action type mentioned above.
Remember that an in-depth understanding and correct application of table relationship behaviors and cascading rules make your Power Apps solutions more efficient. Always ensure that your configurations match your business requirements to help users minimize manual record management. Fine-tune your skills and knowledge in these areas, and you’ll be better equipped to ace the PL-200 Microsoft Power Platform Functional Consultant exam.

- Answer: False
Explanation: There are several types of cascading behaviors, including Cascade None, Cascade All, Cascade User-Owned, Cascade Active, and more.
What does the Cascading behavior ‘Cascade None’ do in Microsoft Power Platform?
- A. It cascades the action to all related records
- B. It cascades the action to no related records
- C. It cascades the action to only user-owned records
- D. It cascades the action to all related active records
Answer: B
Explanation: ‘Cascade None’ does not cascade the action to any related records.
True or False: The ‘Cascade All’ cascading behavior in Microsoft Power Platform cascades the action only to the records related to the deleted record.
- Answer: True
Explanation: ‘Cascade All’ will cascade the action to all records related to the deleted record.
Which cascading behavior cascades the action only to related records that are owned by the user?
- A. Cascade All
- B. Cascade User-Owned
- C. Cascade Active
- D. Cascade None
Answer: B
Explanation: ‘Cascade User-Owned’ cascades the action only to the related records that are owned by the user.
True or False: All cascading rules require manual configuration.
- Answer: False
Explanation: Whilst some rules might require manual configuration, many cascading behaviors are set by default depending on entity relationships.
Which cascading behavior dismisses any cascading action?
- A. Cascade None
- B. Cascade All
- C. Cascade User-Owned
- D. Cascade Active
Answer: A
Explanation: ‘Cascade None’ dismisses any cascading action.
Multi-select: Which of the following can be the possible actions triggering the cascade behaviors?
- A. Assign
- B. Reparent
- C. Delete
- D. Merge
Answer: A, B, C, D
Explanation: All the listed options can trigger the cascade behaviors in Microsoft Power Platform.
True or False: You cannot modify the default cascading behavior settings.
- Answer: False
Explanation: The default cascading behavior settings can be changed as per the requirement.
What is the effect of ‘Cascade Active’ behavior?
- A. It cascades the action to all active related records
- B. It cascades the action to all related records
- C. It cascades the action to no related records
- D. It cascades the action to related records owned by the user
Answer: A
Explanation: The ‘Cascade Active’ cascades the action to all related active records in the system.
True or False: Configuring table relationship behaviors in Microsoft Power Platform helps maintain data consistency and integrity.
- Answer: True
Explanation: Configuring these behaviors help in defining how actions like Assign, Delete, Share, Unshare, etc., should be performed on related records, ensuring data consistency and integrity.
Interview Questions
What is the function of Cascading Rules in configuring table relationship behaviors in Microsoft Power Platform?
Cascading rules determine the kind of action that should occur when specific operations are performed on related records. This can include deletion, reassignment, and sharing of records.
What are the different types of cascading behaviors in Microsoft Power Platform?
The different types of cascading behaviors are: Cascade All, Cascade None, Cascade Active, Cascade User Owned, and Cascade Parental.
What do we mean by ‘Cascade All’ in configuring table relationship behaviors in Microsoft Power Platform?
‘Cascade All’ means that the action taken on the parent will be cascaded to all the associated child records.
What does the behavior ‘Cascade None’ represent in configuring table relationship behaviors?
‘Cascade None’ means that the action taken on the parent record has no impact on the associated child records.
What does the ‘Cascade Active’ behavior mean in configuring table relationship behavior?
‘Cascade Active’ means that the action taken on the related parent record applies only to child records that are active.
What is the function of the ‘Cascade User-Owned’ rule in the configuration of table relationship behaviors in Microsoft Power Platform?
‘Cascade User-Owned’ applies the cascading action only to child records that are owned by the user who triggered the action on the parent record.
Name the cascading rule that propagates changes from a record to its associated records in a 1:N relationship?
The ‘Cascade Parental’ rule is the appropriate cascading rule for such function in a 1:N relationship.
What does ‘Remove Link’ do in Cascading Rules while configuring table relationship behaviors?
‘Remove Link’ action de-links the child records from the parent record but does not delete them.
What does the ‘Cascade Parental’ behavior mean in configuring table relationship behavior?
‘Cascade Parental’ indicates that any operation performed on the parent record will also be performed on its child records.
How does the ‘Restrict’ action play a role in Cascading Rules?
The ‘Restrict’ action in Cascading Rules is used to prevent certain operations from occurring when there are associated child records.
What is the purpose of the ‘Cascade by Entity’ option in the Cascading Rules?
The ‘Cascade by Entity’ option allows the cascading behavior to be set based on the entity type, giving more control over what happens with associated records when an action is taken on a parent record.
What kind of control does the Microsoft Power Platform provide over cascading behaviors?
Microsoft Power Platform provides fine-grained control over the cascading behavior allowing the users to dictate the propagation routines of the actions of delete, assign, share and unshare records.
What will happen if you delete a record that has associated child records, and the ‘Cascade All’ rule is set?
If the ‘Cascade All’ rule is set and you attempt to delete a record that has associated child records, the delete operation would also be performed on all related child records.
Can we modify built-in cascading rules or create new ones in Microsoft Power Platform?
Yes, Microsoft Power Platform allows modification of built-in cascading rules and creation of new ones to suit specific requirements.
How can we set the cascading rules in Microsoft Power Platform?
We can set the cascading rules from the “Relationship Behavior” section present in the “Relationship Definition” dialog box. Different cascading behaviors can be set for different actions like Assign, Share, Unshare, Delete, and Merge.
