  The SAP error message /BOBF/CONF_MODEL_API056 Target Attribute has to be 'KEY' (&1) typically occurs in the context of Business Object Framework (BOBF) when there is an issue with the configuration of a business object or when trying to access or manipulate data in a way that violates the expected structure of the business object.
  Cause:
  
  Incorrect Configuration: The error usually indicates that the target attribute you are trying to access or manipulate is not defined as a key attribute in the business object configuration. In BOBF, key attributes are essential for uniquely identifying records.
  Data Model Issues: There may be a mismatch in the data model where the expected key attribute is not correctly set up or is being referenced incorrectly.

  Solution:
  
  
  Check Business Object Configuration:
  
  Go to the BOBF configuration for the relevant business object.
  Ensure that the attribute you are trying to use as a target is indeed defined as a key attribute.

  Review API Calls:
  
  If you are using an API to interact with the business object, ensure that you are passing the correct parameters.
  Verify that the attribute you are using in your API call is a key attribute as required by the API documentation.
  
  
  
  Debugging:
