• What is the cause and solution for SAP error message /BOBF/CONF_MODEL_API048 - Target Attribute is key: multiplicity 0..1 or 1..1 is required (&1) ?

  The SAP error message /BOBF/CONF_MODEL_API048 indicates that there is an issue with the configuration of a business object in the Business Object Processing Framework (BOPF). Specifically, the error message states that a target attribute is defined as a key attribute, but the multiplicity defined for that attribute does not match the expected multiplicity of 0..1 or 1..1. 
  Cause:
  
  Key Attribute Definition: The attribute in question is defined as a key attribute in the BOPF model, which means it is expected to uniquely identify an instance of the business object.
  Multiplicity Mismatch: The multiplicity defined for the target attribute does not align with the requirements for key attributes. Key attributes should have a multiplicity of either 0..1 (optional) or 1..1 (mandatory).
  Model Configuration Error: There may be a misconfiguration in the BOPF model where the attribute's multiplicity is set incorrectly.
  
  Solution:
  
  
  Check BOPF Model Configuration:
  
  Go to the BOPF model configuration in the SAP system.
  Identify the business object and locate the target attribute that is causing the error.
  Verify the multiplicity settings for the attribute. Ensure that it is set to either 0..1 or 1..1 if it is a key attribute.
  
  
  
  Adjust Multiplicity:
  
  If the multiplicity is set incorrectly, adjust it to the appropriate value (0..1 or 1..1).
  Save the changes and regenerate the BOPF model if necessary.
  
  
  
  Test the Changes:
  
  After making the adjustments, test the business object to ensure that the error no longer occurs.
  
  
  
  Consult Documentation:
  
  If you are unsure about the correct configuration, refer to the SAP documentation for BOPF and key attributes to understand the requirements better.
