• What is the cause and solution for SAP error message /BOBF/CONF302 - Table type &1 of node &2 shall not use a unique &3 key ?

  The SAP error message /BOBF/CONF302 indicates that there is a configuration issue related to the Business Object Processing Framework (BOPF) in SAP. Specifically, this error occurs when a node in a BOPF business object is configured to use a unique key for a table type that does not support it.
  Cause:
  
  Incorrect Configuration: The node in question is configured to use a unique key, but the underlying table type does not support unique keys. This can happen if the table type is designed to allow multiple entries (non-unique) but is incorrectly set up to enforce uniqueness.
  Data Model Design: The data model may not align with the intended use of the BOPF node, leading to a mismatch between the key definition and the table type.
  
  Solution:
  
  Review Node Configuration: Check the configuration of the BOPF node in the BOPF configuration transaction (e.g., transaction BOPF). Ensure that the key definition aligns with the table type being used.
  Change Key Type: If the table type is indeed non-unique, change the key definition of the node to a non-unique key. This can be done in the BOPF configuration settings.
  Adjust Data Model: If the data model requires a unique key, consider changing the underlying table type to one that supports unique keys, or redesign the data model to accommodate the existing table type.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on configuring BOPF nodes and understanding the implications of key types.
  
  Related Information:
  
  BOPF Documentation: SAP provides extensive documentation on the Business Object Processing Framework, which can help in understanding how to configure nodes and keys properly.
  SAP Notes: Check for any relevant SAP Notes that might address specific issues or provide patches related to BOPF configuration.
  Community Forums: Engage with SAP community forums or support channels where similar issues may have been discussed, providing insights or solutions from other users.
  
  By following these steps, you should be able to resolve the error and ensure that your BOPF configuration is set up correctly.
