• What is the cause and solution for SAP error message FDT_EXPRESSIONS102 - Provide exactly one result or condition for node &1 ?

  The SAP error message FDT_EXPRESSIONS102 typically occurs in the context of using the SAP Fiori Design Time (FDT) or when working with expressions in SAP applications. This error indicates that the system expects exactly one result or condition for a specified node, but it has found either none or multiple results.
  Cause:
  The primary cause of this error is that the expression or condition defined for a node is ambiguous or not properly defined. This can happen if:
  
  The expression is returning multiple values when only one is expected.
  The logic in the expression is not correctly filtering the data to yield a single result.
  There is a misconfiguration in the data model or the expression itself.
  
  Solution:
  To resolve the FDT_EXPRESSIONS102 error, you can take the following steps:
  
  
  Review the Expression: Check the expression or condition defined for the node. Ensure that it is designed to return a single value. If it is supposed to filter data, make sure the filtering criteria are specific enough to yield only one result.
  
  
  Debug the Logic: If you are using complex logic or calculations, debug the expression to see what values it is returning. You can use tools like the expression editor or debugging tools in SAP to analyze the output.
  
  
  Check Data Model: Ensure that the data model associated with the node is correctly set up. Verify that the relationships and cardinalities are defined properly, which can help in ensuring that the expression returns a single result.
  
  
  Use Aggregation Functions: If applicable, consider using aggregation functions (like SUM, MAX, MIN, etc.) to ensure that the expression condenses multiple values into a single result.
  
  
  Consult Documentation: Refer to SAP documentation or community forums for specific examples and best practices related to the expression you are working with.
  
  
  Testing: After making changes, test the expression again to confirm that it now returns exactly one result for the specified node.
  
  
  Related Information:
  
  SAP Fiori Design Time (FDT): This is a framework that allows developers to create and manage Fiori applications. Understanding how expressions work within this framework is crucial for troubleshooting.
  Expression Editor: Familiarize yourself with the expression editor in SAP, which can help you build and test expressions interactively.
  SAP Community: Engage with the SAP Community for insights and solutions from other users who may have encountered similar issues.
