• What is the cause and solution for SAP error message DBOSC109 - Error while performing dynamic call; missing parameter for &1->&2() ?

  The SAP error message DBOSC109 indicates that there is an issue with a dynamic call in your ABAP code, specifically that a required parameter is missing for a method or function call. The message format typically looks like this: "Error while performing dynamic call; missing parameter for &1->&2()", where &1 represents the object (class or interface) and &2 represents the method being called.
  Cause
  The error can occur due to several reasons:
  
  Missing Parameters: The method being called requires certain parameters that are not being provided in the dynamic call.
  Incorrect Method Signature: The method signature may have changed, and the code is not updated to reflect the new parameters.
  Dynamic Call Syntax: The syntax used for the dynamic call may be incorrect, leading to the method not being called properly.
  Data Type Mismatch: The parameters being passed may not match the expected data types of the method.
  
  Solution
  To resolve the DBOSC109 error, you can follow these steps:
  
  
  Check Method Signature: Verify the method signature of the class or interface being called. Ensure that you are passing all required parameters in the correct order and with the correct data types.
  
  
  Update Dynamic Call: If the method signature has changed, update your dynamic call to include the necessary parameters. For example, if you are using CALL METHOD dynamically, ensure that you are passing the correct parameters.
  DATA: lo_object TYPE REF TO your_class,
        lv_param1 TYPE your_type,
        lv_param2 TYPE your_type.
  
  CALL METHOD (lo_object)->(method_name)
    EXPORTING
      param1 = lv_param1
      param2 = lv_param2.
  
  
  Debugging: Use the debugger to step through the code and check the values being passed to the method. This can help identify if any parameters are missing or incorrectly set.
  
  
  Review Documentation: If you are using standard SAP methods or classes, refer to the SAP documentation to ensure you understand the required parameters and their types.
  
  
  Error Handling: Implement error handling to catch such issues in the future. You can use TRY...ENDTRY blocks to manage exceptions and provide meaningful error messages.
