• What is the cause and solution for SAP error message SDCBO136 - Node & is external in parent node &; was already defined in append <> & ?

  The SAP error message SDCBO136 typically occurs in the context of SAP's data model or configuration, particularly when dealing with Business Object (BO) definitions in the SAP Cloud Application Studio or similar environments. This error indicates that a node is being defined as both an external node and as a child node in a parent node, which is not allowed.
  Cause:
  The error arises when:
  
  You have defined a node in a business object (BO) that is marked as an external node.
  The same node is also being defined as a child node of another parent node within the same BO or in a related context.
  This creates a conflict because an external node cannot be a child of another node.
  
  Solution:
  To resolve the SDCBO136 error, you can take the following steps:
  
  
  Review Node Definitions:
  
  Check the definitions of the nodes in your business object. Identify the node that is causing the conflict (the one mentioned in the error message).
  Ensure that the node is not defined as both an external node and a child node.
  
  
  
  Modify Node Configuration:
  
  If the node needs to remain as an external node, remove it from being defined as a child node in any parent node.
  Alternatively, if the node should be a child node, change its configuration to remove the external designation.
  
  
  
  Check for Appends:
  
  The error message mentions an append. If you are using an append structure, ensure that the node is not being defined in multiple places in a way that conflicts with its external status.
  
  
  
  Test Changes:
  
  After making the necessary changes, save your configuration and test to ensure that the error no longer appears.
  
  
  
  Documentation and Best Practices:
  
  Refer to SAP documentation for best practices on defining nodes in business objects.
  Ensure that you are following the guidelines for external nodes and their relationships with other nodes.
