• What is the cause and solution for SAP error message /BOBF/CONF_CDS029 - [BO check] Active Entity DB fields not marked as KEY (view &1, table &2) ?

  The SAP error message /BOBF/CONF_CDS029 [BO check] Active Entity DB fields not marked as KEY (view &1, table &2) typically occurs in the context of Business Object Framework (BOF) and Core Data Services (CDS) views in SAP. This error indicates that there are fields in the database table that are not marked as key fields, which is a requirement for the active entity in the Business Object.
  Cause:
  
  Missing Key Definition: The error arises when the CDS view or the underlying database table does not have the necessary key fields defined. In a Business Object, certain fields must be designated as keys to uniquely identify records.
  Incorrect Configuration: The configuration of the Business Object or the CDS view may not align with the underlying database structure, leading to discrepancies in key field definitions.
  Changes in Database Structure: If the database structure has been modified (e.g., fields added or removed) without updating the corresponding CDS view or Business Object configuration, this error can occur.
  
  Solution:
  
  
  Check Key Field Definition:
  
  Open the CDS view or the underlying database table in the ABAP Development Tools (ADT).
  Ensure that the necessary fields are marked as key fields. You can do this by checking the @Key annotation in the CDS view definition.
  
  
  
  Update Business Object Configuration:
  
  If you are using a Business Object, ensure that the configuration reflects the correct key fields. You may need to adjust the configuration in the Business Object Builder (BOB) to include the appropriate key fields.
  
  
  
  Regenerate the CDS View:
  
  If changes were made to the underlying database structure, regenerate the CDS view to ensure it reflects the current state of the database.
  
  
  
  Check for Consistency:
  
  Use transaction /BOBF/CONF to check for consistency in the Business Object configuration. This transaction can help identify any discrepancies between the Business Object and the underlying data model.
  
  
  
  Transport Changes:
  
  If you are working in a development environment, ensure that any changes made are transported to the appropriate systems (e.g., quality assurance, production) to maintain consistency.
