• What is the cause and solution for SAP error message FRMLDLG221 - Only one primary output may exist ?

  The SAP error message FRMLDLG221 ("Only one primary output may exist") typically occurs in the context of SAP's Formulas and Functions, particularly when dealing with the definition of outputs in a formula or a function module. This error indicates that the system has detected multiple primary outputs defined in a single formula or function, which is not allowed.
  Cause:
  The primary cause of this error is the definition of more than one primary output in a formula or function. In SAP, a primary output is the main result that a formula or function is expected to return. Having multiple primary outputs can lead to ambiguity in the results, which is why the system restricts it to only one.
  Solution:
  To resolve this error, you need to ensure that your formula or function has only one primary output defined. Here are the steps you can take:
  
  
  Review the Formula/Function Definition:
  
  Open the formula or function module where the error is occurring.
  Check the output parameters defined in the formula.
  
  
  
  Identify Primary Outputs:
  
  Look for the parameters that are marked as primary outputs. In many cases, this is indicated in the definition screen.
  
  
  
  Modify the Definition:
  
  If you find multiple primary outputs, decide which one should be the primary output.
  Change the definition to ensure that only one output is marked as primary. You may need to adjust the logic of your formula to accommodate this change.
  
  
  
  Test the Changes:
  
  After making the necessary adjustments, save the changes and test the formula or function to ensure that it works as expected without triggering the error.
  
  
  
  Documentation:
  
  Document the changes made for future reference and to help other developers understand the logic behind the formula.
  
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for more details on defining formulas and functions, including best practices for output parameters.
  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and how they resolved them.
  Debugging: If the error persists after making changes, consider using debugging tools within SAP to trace the execution of the formula and identify any other potential issues.
  
  By following these steps, you should be able to resolve the FRMLDLG221 error and ensure that your formula or function operates correctly within the SAP environment.
