What causes this issue?

A cyclic dependency between CDS Views was detected, which may lead to
activation errors:
when customer creates a new Datasource Extension and selects a field
from one of the dependent Views.
when the cyclic dependency was added later and already created
Datasource Extensions exist on customer side. In this case even the
upgrade or hotfix import would fail!

• What is the cause and solution for SAP error message CFD_REGISTRY_CHECK382 - Cyclic Dependency detected where DSExtension may cause activation errors ?

  The SAP error message CFD_REGISTRY_CHECK382 indicates that there is a cyclic dependency detected in the Data Source Extension (DSExtension) configuration. This typically occurs when two or more components depend on each other in a way that creates a loop, preventing the system from activating or processing them correctly.
  Cause:
  
  Cyclic Dependencies: The most common cause of this error is that two or more DSExtensions reference each other in a way that creates a cycle. For example, if DSExtension A depends on DSExtension B, and DSExtension B also depends on DSExtension A, this creates a cyclic dependency.
  Incorrect Configuration: Misconfiguration of the DSExtensions or their dependencies can lead to this issue.
  Changes in Data Model: If there have been recent changes in the data model or the DSExtensions, it might have inadvertently created a cyclic dependency.
  
  Solution:
  
  Identify Dependencies: Review the dependencies of the DSExtensions involved. You can do this by checking the configuration of each DSExtension to see which other DSExtensions they depend on.
  Refactor Dependencies: Once you identify the cyclic dependencies, you will need to refactor the DSExtensions to eliminate the cycle. This may involve:
  
  Removing unnecessary dependencies.
  Redesigning the data model to avoid circular references.
  Splitting DSExtensions into smaller, more manageable components if necessary.
  
  
  Testing: After making changes, test the DSExtensions to ensure that they activate correctly and that the cyclic dependency error is resolved.
  Documentation: Document the changes made to the DSExtensions and their dependencies to prevent similar issues in the future.
