• What is the cause and solution for SAP error message 28122 - Multiple-value formal parameter &1 in table/function &2 ?

  The SAP error message 28122, which states "Multiple-value formal parameter &1 in table/function &2," typically occurs when a function module or method is called with a parameter that is expected to accept a single value, but multiple values are being passed instead. This can happen in various scenarios, such as when using a table parameter that is not properly defined or when the calling program does not match the expected input structure.
  Cause:
  
  Incorrect Parameter Type: The function module or method is defined to accept a single value for a parameter, but the calling program is passing a table or multiple values.
  Data Type Mismatch: The data type of the parameter being passed does not match the expected data type in the function module or method.
  Improper Use of Structures: If a structure is expected but a table is passed, or vice versa, this error can occur.
  
  Solution:
  
  Check Function Module/Method Definition: Review the definition of the function module or method to understand the expected parameters. Ensure that you are passing the correct type and number of parameters.
  Adjust Parameter Passing: If you are passing a table, ensure that you are using the correct parameter that is defined to accept a table. If a single value is expected, ensure that you are passing only one value.
  Use Appropriate Data Types: Make sure that the data types of the parameters being passed match the expected data types in the function module or method.
  Debugging: Use the debugger to trace the values being passed to the function/module. This can help identify where the multiple values are coming from and how to correct them.
  
  Related Information:
  
  SAP Documentation: Refer to the SAP documentation for the specific function module or method to understand its parameters and expected input.
  ABAP Development: If you are an ABAP developer, familiarize yourself with the concepts of parameter passing, especially the differences between single-value parameters and table parameters.
  Community Forums: Check SAP community forums or support sites for similar issues and solutions shared by other users.
  
  By following these steps, you should be able to resolve the error message 28122 and ensure that the parameters being passed to the function module or method are correct.
