• What is the cause and solution for SAP error message /BOBF/CONF157 - Field &1 of alternative key &2 node &3 is not mapped to any proxy field ?

  The SAP error message /BOBF/CONF157 indicates that there is a problem with the mapping of fields in the Business Object Processing Framework (BOPF). Specifically, it means that a field in the alternative key of a node is not mapped to any proxy field, which can lead to issues when trying to access or manipulate data related to that node.
  Cause:
  
  Field Mapping Issue: The field specified in the error message is not correctly mapped to a corresponding field in the proxy. This can happen if the field was removed or renamed in the data model but the mapping was not updated accordingly.
  Configuration Error: There may be a configuration error in the BOPF definition where the alternative key is defined.

  Solution:
  
  
  Check Field Mapping:
  
  Go to the BOPF configuration for the relevant business object.
  Verify that the field mentioned in the error message is correctly mapped to a proxy field. If it is not, you will need to create or update the mapping.

  Regenerate Proxy:
