• What is the cause and solution for SAP error message FDT_EXPRESSIONS211 - Invalid row number specified; row &1 does not exist in decision table ?

  The SAP error message FDT_EXPRESSIONS211 indicates that there is an issue with a decision table in the context of the Flexible Decision Table (FDT) framework. Specifically, the error states that an invalid row number has been specified, meaning that the row number referenced does not exist in the decision table.
  Cause:
  
  
  Row Number Reference: The error typically occurs when a process or function is trying to access a row in the decision table that is either out of bounds or does not exist. This can happen if:
  
  The decision table has been modified (rows added or deleted) after the reference was created.
  There is a programming error in the logic that references the row number.
  The decision table is empty or has fewer rows than expected.
  
  
  
  Data Integrity Issues: If there are inconsistencies in the data or if the decision table was not properly initialized, it could lead to this error.
  
  
  Configuration Issues: Incorrect configuration of the decision table or its associated rules can also lead to this error.
  
  
  Solution:
  
  
  Check Decision Table: Verify the decision table to ensure that the row number being referenced actually exists. You can do this by:
  
  Opening the decision table in the FDT editor and checking the number of rows.
  Ensuring that the row number being accessed is within the valid range.
  
  
  
  Review Code Logic: If the error is occurring in custom code or a specific function, review the logic to ensure that it correctly references existing rows. Make sure that any dynamic references to row numbers are correctly calculated.
  
  
  Reinitialize or Update: If the decision table has been modified, consider reinitializing or updating the relevant configurations to ensure that all references are valid.
  
  
  Debugging: If you have access to debugging tools, you can set breakpoints and inspect the values being passed to the decision table to identify where the invalid row number is being generated.
  
  
  Consult Documentation: Review SAP documentation or notes related to the FDT framework for any known issues or updates that might address this error.
  
  
  Contact SAP Support: If the issue persists and you cannot identify the cause, consider reaching out to SAP support for assistance. Provide them with details about the error, the context in which it occurs, and any relevant configurations.
