When you encounter the issue of sub-grid data not loading in Power Pages, there can be multiple factors at play, ranging from permission issues, improper configuration of the sub-grid, or data filtering problems. Below is a detailed step-by-step guide to troubleshooting and resolving this issue.
1. Check Entity Permissions
The first step is to ensure that the user has the correct permissions to view the data related to the sub-grid.
Steps to verify:
- Review User Permissions:
- Go to Portal Management and check the user’s role in the Portal User record. The user needs to have read access to the related entities for the sub-grid to load.
- Entity Permissions:
- Ensure that the Entity Permissions associated with the sub-grid’s entities allow read access. If there is no read access set for the entity, the sub-grid will not display any data.
- Web Roles:
- Verify that the Web Role assigned to the user allows access to the sub-grid data by ensuring the role has the appropriate permissions for the related entities. For example, if the sub-grid is pulling data from the “Contact” entity, ensure that the Web Role grants access to this entity.
2. Check Sub-grid Configuration
Proper configuration of the sub-grid is essential for the data to load correctly. Ensure that the sub-grid is set up to display the correct related data.
Steps to verify:
- Open the Entity Form Configuration:
- Go to Portal Management and locate the form where the sub-grid is embedded.
- Sub-grid Settings:
- Ensure that the sub-grid properties are configured correctly, such as:
- The entity the sub-grid is pulling data from.
- The relationship between the parent and related entity is properly defined.
- Ensure that the view selected for the sub-grid is correct and contains data.
- Ensure that the sub-grid properties are configured correctly, such as:
- Check Filters:
- If you are applying any filters to the sub-grid (e.g., data based on specific criteria), make sure these filters are not too restrictive, causing the sub-grid to display no data.
- Sub-grid View:
- Check if the view used for the sub-grid in the configuration is pulling the right data. Sometimes, sub-grids might be configured to use a specific view that has limited or no records.
3. Verify Data Relationships
Incorrect or missing data relationships between entities can cause sub-grid data not to load.
Steps to verify:
- Check Relationship Setup:
- Ensure that the relationship between the parent entity (e.g., “Account”) and the related entity (e.g., “Contact”) is properly configured in Dataverse.
- Verify Data in Related Entity:
- Ensure that there are actual records in the related entity that satisfy the relationship criteria. For instance, if the sub-grid is pulling data from the “Contacts” entity, ensure that the “Account” field in the related “Contact” records is populated.
- Relationship Type:
- Check the relationship type (1:N, N:1, N:N) in Dataverse. Ensure that the correct relationship is set up and there is no misconfiguration leading to missing data in the sub-grid.
4. Ensure Proper Access to Data Views
If the sub-grid is pulling data from a specific view, it’s important to ensure that the view is accessible and not restricted.
Steps to verify:
- Check the View Permissions:
- Go to Power Apps and navigate to the view used by the sub-grid. Ensure that the view is not restricted based on any conditions (e.g., security filters).
- Access for Portal Users:
- Ensure that the Portal User has access to the view. This is important as the data displayed in the sub-grid may be controlled by the security of the view.
5. Check for JavaScript Errors
Sometimes, JavaScript running on the page can interfere with the loading of sub-grid data, causing it to fail.
Steps to verify:
- Inspect the Console:
- Open your browser’s Developer Tools (usually F12) and check the Console for any JavaScript errors. JavaScript issues, especially with custom scripts interacting with the sub-grid, may prevent the data from loading.
- Disable Custom Scripts:
- If you have custom scripts interacting with the sub-grid, try temporarily disabling them to see if the issue persists. Custom JavaScript may override the default behavior and cause the sub-grid not to load correctly.
6. Clear Cache and Test in Incognito Mode
Cache and browser-related issues can sometimes cause sub-grid data not to display correctly.
Steps to verify:
- Clear Browser Cache:
- Clear your browser’s cache and cookies to ensure there is no outdated data that might be causing the issue.
- Test in Incognito Mode:
- Open the portal in Incognito Mode or Private Browsing to avoid any cached data interfering with the sub-grid display.
7. Verify the Portal Configuration
Sometimes, portal-level issues such as incorrect site settings can cause data to not load in the sub-grid.
Steps to verify:
- Portal Settings:
- Ensure that the portal settings are correctly configured. This includes verifying the Entity Permissions, Web Roles, and Entity Forms.
- Portal Maintenance:
- Perform a basic portal health check to ensure no issues are impacting its ability to load data. This can include checking for any outages or issues that might be affecting the sub-grid’s ability to fetch data from Dataverse.
8. Test with Different User Roles
If you suspect the issue is role-based, try testing the portal with different user roles to check if the sub-grid data loads correctly for certain users.
Steps to verify:
- Assign Different Web Roles:
- Assign different Web Roles to test users and verify if the sub-grid loads data for all roles. This will help isolate if the issue is related to a specific role’s permissions.
Conclusion
By following these troubleshooting steps, you can systematically identify and resolve issues with sub-grid data not loading in Power Pages. Whether it’s related to permissions, data relationships, or configuration, ensuring that all components are correctly set up is key to ensuring proper sub-grid functionality.
