• What is the cause and solution for SAP error message GU121 - Missing "&" ?

  The SAP error message GU121, which states "Missing '&'", typically occurs in the context of SAP's output management or when dealing with forms and print layouts. This error indicates that there is a missing or incorrectly defined parameter in the output configuration, particularly in the context of using the "&" symbol, which is often used to denote variables or placeholders in SAP scripts or Smart Forms.
  Cause:
  
  Missing Variable: The error usually arises when a variable that is expected to be defined in the output form or script is not present or is incorrectly referenced.
  Incorrect Syntax: There may be a syntax error in the form or script where the "&" symbol is used, leading to the system being unable to interpret the intended variable.
  Configuration Issues: The output type or the associated configuration may not be set up correctly, leading to missing parameters.

  Check the Form/Script: Review the Smart Form or SAPscript where the error is occurring. Ensure that all variables referenced with "&" are correctly defined and exist in the context of the form.
  Correct Syntax: Ensure that the syntax used for referencing variables is correct. For example, in Smart Forms, variables should be referenced as &variable_name&.
  Review Output Configuration: Check the output type configuration in transaction NACE or the relevant transaction for output management. Ensure that all necessary parameters are defined and correctly set up.
  Test the Output: After making corrections, test the output again to see if the error persists. Use transaction codes like VF03 (for billing documents) or ME23N (for purchase orders) to trigger the output and check for errors.
  Debugging: If the issue is not resolved, consider debugging the form or script to identify where the missing variable is being referenced.
