Prerequisite
Before making any changes to a custom CDS view, check if the respective
custom CDS view has any dependencies to other objects. You can find all
dependencies in the Extensibility Inventory app. If the underlying data
sources contain errors, these errors must be corrected first.
Your custom CDS view is missing keys from the primary data source. A
custom view must contain all key from underlying data sources to
properly inherit the access protection.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

1. Search for your custom CDS view in the Extensibility Inventory app to
see the complete CDS view stack
2. Start republishing from the lowest primary data source (root view)
and republish upwards until you have reached the top-most custom CDS
view of the stack. Before you republish, the missing key fields must be
added manually.

  Missing Key Fields: The CDS view is expected to have certain key fields defined, but they are either missing or not properly defined in the view.
  Changes in Underlying Tables: If the underlying tables or data sources for the CDS view have changed (e.g., fields added or removed), it may lead to inconsistencies in the view definition.
  Inconsistent Metadata: The metadata for the CDS view may be out of sync, especially if there have been recent changes to the data model or if the view has not been republished after changes.
