• What is the cause and solution for SAP error message CL290 - Class has no index characteristics - existing tables are being deleted ?

  The SAP error message CL290 indicates that a class does not have any index characteristics defined, and as a result, existing tables related to that class are being deleted. This typically occurs in the context of class-based object-oriented programming in SAP, particularly when dealing with characteristics in classification systems.
  Cause:
  
  No Index Characteristics Defined: The primary cause of this error is that the class in question does not have any index characteristics defined. Index characteristics are essential for the classification system to function correctly, as they allow for efficient data retrieval and management.
  Deletion of Existing Tables: When a class lacks index characteristics, SAP may attempt to clean up by deleting related tables that are no longer valid or necessary.
  
  Solution:
  To resolve this error, you need to ensure that the class has index characteristics defined. Here are the steps to do this:
  
  
  Access the Class:

  Enter the class name that is causing the error.
  
  
  
  Define Index Characteristics:
  
  Navigate to the Characteristics tab.

  To create a new characteristic, you can use transaction code CT04 (Create Characteristic). Ensure that the characteristic is set as an index characteristic.
  
  
  
  Assign Characteristics to the Class:
  
  Once you have created the necessary characteristics, go back to the class and assign these characteristics to it.
  Make sure to mark the characteristics as index characteristics if required.
  
  
  
  Save Changes: After making the necessary changes, save the class.
  
  
  Check for Consistency: After saving, you may want to run a consistency check to ensure that the class and its characteristics are correctly set up.
