• What is the cause and solution for SAP error message DDLS187 - Function & expects & parameters; current number is & ?

  The SAP error message DDLS187 indicates that there is a mismatch between the expected number of parameters for a function and the actual number of parameters being passed to it. This error typically occurs in the context of ABAP programming, particularly when dealing with function modules or methods.
  Cause:
  The error message DDLS187 is triggered when:
  
  A function module or method is defined to accept a specific number of parameters, but the call to that function/module provides either too few or too many parameters.
  The parameters may include input parameters, output parameters, or both, and the mismatch can occur in any of these categories.
  
  Solution:
  To resolve the DDLS187 error, you can follow these steps:
  
  
  Check Function Module/Method Definition:
  
  Go to the function module or method definition in the ABAP Workbench (transaction SE37 for function modules or SE80 for classes/methods).
  Verify the number of parameters defined and their types.
  
  
  
  Review the Call:
  
  Locate the code where the function module or method is being called.
  Ensure that the number of parameters being passed matches the definition. Adjust the call to include the correct number of parameters.
  
  
  
  Parameter Types:
  
  Ensure that the types of the parameters being passed match the expected types in the function/module definition. Mismatched types can also lead to errors.
  
  
  
  Documentation:
  
  If available, refer to the documentation for the function module or method to understand its expected parameters and their purposes.
  
  
  
  Testing:
  
  After making the necessary adjustments, test the code to ensure that the error is resolved.
  
  
  
  Related Information:
  
  
  Transaction Codes:
  
  SE37: Function Module
  SE80: Object Navigator (for classes and methods)
  SE11: Data Dictionary (to check data types if needed)
  
  
  
  Debugging:
  
  Use the ABAP debugger to step through the code and inspect the parameters being passed to the function/module. This can help identify where the mismatch occurs.
  
  
  
  SAP Notes:
  
  Check for any relevant SAP Notes that might address specific issues related to the function/module you are working with.
  
  
  
  By following these steps, you should be able to identify and correct the cause of the DDLS187 error in your SAP environment.
