• What is the cause and solution for SAP error message /BOBF/CONF_MODEL_API050 - Source Attribute has to be a Node component, not an Alternative Key (&1) ?

  The SAP error message /BOBF/CONF_MODEL_API050 indicates that there is an issue with the configuration of a Business Object Framework (BOF) model in SAP. Specifically, the error states that the source attribute you are trying to use must be a node component rather than an alternative key.
  Cause:
  This error typically occurs when:
  
  You are trying to map or reference an attribute in a Business Object that is defined as an alternative key instead of a node component.
  The configuration of the Business Object is incorrect, where the expected structure does not match the actual structure defined in the model.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Business Object Configuration:
  
  Open the Business Object in the SAP Business Object Framework (BOF) configuration.
  Verify the attributes and ensure that the source attribute you are trying to use is defined as a node component.
  
  
  
  Modify the Attribute Definition:
  
  If the attribute is incorrectly defined as an alternative key, you may need to change its definition to a node component.
  Ensure that the attribute you are trying to use is appropriate for the context in which it is being referenced.
  
  
  
  Review the Mapping:
  
  If you are working with a mapping or transformation, ensure that you are referencing the correct attributes. Make sure that the source and target attributes align correctly in terms of their definitions.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for the Business Object Framework to understand the correct usage of node components and alternative keys.
