• What is the cause and solution for SAP error message DD_CDS_ANALYSIS017 - Table name & unknown or shadowed by an alias ?

  The SAP error message DD_CDS_ANALYSIS017 typically indicates that there is an issue with a table name being either unknown or shadowed by an alias in the context of Core Data Services (CDS) views. This error can occur during the activation or execution of a CDS view when the system cannot resolve the table name correctly.
  Cause:
  
  Unknown Table Name: The table name specified in the CDS view does not exist in the database or is misspelled.
  Shadowed by Alias: The table name might be shadowed by an alias defined in the CDS view or in the context of the query. This means that the alias is taking precedence over the actual table name, leading to confusion in the resolution process.
  Incorrect Schema: The table might exist but is not accessible due to schema issues or authorization problems.
  Missing Transport: If the CDS view or the underlying table was recently transported, it might not be available in the target system.
  
  Solution:
  
  Check Table Name: Verify that the table name used in the CDS view is correct and exists in the database. You can do this by checking in the Data Dictionary (SE11).
  Review Aliases: Look for any aliases defined in the CDS view. Ensure that the alias is not conflicting with the actual table name. If necessary, rename the alias or adjust the query to avoid shadowing.
  Schema Verification: Ensure that the table is in the correct schema and that you have the necessary authorizations to access it.
  Transport Check: If the issue arose after a transport, ensure that all necessary objects (including the table and any related objects) have been transported correctly.
  Re-activate the CDS View: After making the necessary corrections, try to re-activate the CDS view to see if the error persists.
