• What is the cause and solution for SAP error message FDT_CORE754 - Node ID &1 (&2) has children(stuct.node);no leaf/link attributes possible ?

  The SAP error message FDT_CORE754 indicates that there is an issue with the structure of a node in a data model, specifically in the context of Field Data Tool (FDT) or similar frameworks. The message states that the node identified by the ID has children, which means it is not a leaf node, and therefore, it cannot have leaf or link attributes.
  Cause:
  
  Node Structure: The error typically arises when you attempt to assign leaf or link attributes to a node that has child nodes. In FDT, a leaf node is one that does not have any children, while a node with children is considered a parent node.
  Model Configuration: There may be a misconfiguration in the data model where the node is incorrectly defined as a leaf when it actually has child nodes.
  Data Model Design: The design of the data model may not adhere to the expected hierarchy, leading to this error when trying to manipulate or save the model.
  
  Solution:
  
  Check Node Hierarchy: Review the structure of the node with ID &1. Ensure that it is correctly defined as a parent node if it has children. If you intended for it to be a leaf node, you need to remove any child nodes associated with it.
  Modify Attributes: If the node is indeed a parent node, you should not assign leaf or link attributes to it. Instead, assign these attributes to the appropriate leaf nodes in the hierarchy.
  Reconfigure the Data Model: If necessary, reconfigure the data model to ensure that the hierarchy is correctly set up, with clear distinctions between parent and leaf nodes.
  Validation: After making changes, validate the data model to ensure that there are no further structural issues.
  
  Related Information:
  
  FDT Documentation: Refer to the official SAP documentation for Field Data Tool for more details on node structures and attributes.
  SAP Community: Check forums and community discussions for similar issues and solutions shared by other users.
  Debugging: If the issue persists, consider enabling debugging or logging to get more insights into what might be causing the error.
  
  By following these steps, you should be able to resolve the FDT_CORE754 error and ensure that your data model is correctly configured.
