I received the following answer from the professor, ChatGPT. It makes sense to me, so I wanted to share it with you.
This issue occurs when Solution A still has remnants in the form of base layers for components, and Solution B overlays managed layers on top of it. Here's how to resolve it step-by-step:
1. Understand Solution Layers
The error indicates that Solution A has components with dependencies in Solution B. Since Solution B is managed, it prevents direct manipulation of the layers. You'll need to investigate the dependencies and address them systematically.
2. Identify Dependencies
Follow these steps to identify what is preventing Solution A from being deleted:
-
Navigate to the Solution Layers:
- Open the Power Platform Admin Center.
- Go to Solutions in your Test environment.
- Select Solution A and look for the Solution Layers feature (available under the app settings or component options).
-
Examine Components:
- Check the listed components (e.g.,
AppSetting) and note the IDs and solution names where they are referenced.
-
Verify Managed Layers:
- Go to Solution B and verify if the components referenced from Solution A appear under its components list.
3. Resolve Dependencies
The approach depends on the complexity of dependencies:
Option 1: Remove Components in Solution B
If Solution B inadvertently includes components from Solution A:
- Open Solution B in your Test environment.
- Check for shared components (e.g.,
AppSetting).
- Remove the components that reference Solution A (if they are not needed).
- Re-export Solution B as a managed solution and re-import it into Test.
Option 2: Temporary Deletion of Solution B
If Solution B actively depends on Solution A components, consider:
- Export Solution B as a managed solution for backup.
- Delete Solution B from the Test environment.
- Delete Solution A from the Test environment.
- Re-import Solution B into the Test environment.
Option 3: Reassign Components
If Solution B needs components from Solution A, you can attempt to reassign the base layer:
- Extract and examine Solution A’s unmanaged layer in Dev.
- Recreate the components directly in Solution B.
- Re-import Solution B into the Test environment as an updated managed solution.
- Attempt to delete Solution A again.
4. General Best Practices
- Avoid Cross-Solution Dependencies: Ensure components from one solution aren’t inadvertently referenced in another.
- Use Managed Solutions for Production: Deploy managed solutions in Test and Prod to avoid layering issues.
- Always Test in Dev: Test solution updates and deletions in the Dev environment before migrating to Test or Prod.
5. Advanced Tools
If the above steps don’t resolve the issue, you can use advanced tools:
- Power Platform Solution Checker: Helps analyze dependencies.
- XrmToolBox:
- Use the Solution Layer Viewer plugin to see detailed layer relationships.
- Use the Dependency Checker plugin to pinpoint blockers.
6. Microsoft Support
If none of the above resolves the issue, contact Microsoft Support. Include:
- Solution export files for both A and B.
- Dependency details from Solution Layers.
- Screenshots of the error and impacted components.
Summary
The key to resolving this issue is to untangle the dependency between Solution A and Solution B. By carefully analyzing the solution layers and dependencies, you should be able to delete Solution A without impacting Solution B.
