• What is the cause and solution for SAP error message FDT_CORE765 - Node ID &1 (&2) needs to be of type Leaf ?

  The SAP error message FDT_CORE765 indicates that there is an issue with the structure of a node in a data model or configuration within the SAP system, specifically in the context of the Field Data Tool (FDT). The message states that a node identified by its ID needs to be of type "Leaf," which means it should not have any child nodes or further subdivisions.
  Cause:
  
  Incorrect Node Type: The node in question is likely defined as a parent node or a composite node, which can have child nodes, but the system expects it to be a leaf node (a node without children).
  Data Model Configuration: There may be a misconfiguration in the data model where the node is incorrectly set up to allow children when it should not.
  Mapping Issues: If the node is part of a mapping or transformation process, it may be incorrectly defined in the mapping logic.
  
  Solution:
  
  Check Node Definition: Review the definition of the node with ID &1 (&2) in the data model. Ensure that it is correctly defined as a leaf node if that is the intended structure.
  Modify Node Type: If the node is incorrectly set as a parent or composite node, change its type to a leaf node in the configuration settings.
  Review Hierarchy: Ensure that the hierarchy of nodes is correctly structured. If the node should have children, then it may need to be re-evaluated based on the business requirements.
  Testing: After making changes, test the configuration to ensure that the error does not reoccur and that the data model behaves as expected.
  
  Related Information:
  
  FDT (Field Data Tool): This is a tool used in SAP for managing field data and configurations, often used in conjunction with data models for applications like SAP S/4HANA.
