What causes this issue?

Prerequisites
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 contains parameters from the primary data source or
an associated data source. The underlying data types of these parameters
have changed. You need to republish the custom CDS view and, if
required, the dependent CDS view stack.

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

System Response

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. The parameter data types will reflect the data type
changes, once you have republished the custom CDS view.
