• What is the cause and solution for SAP error message CMP_MSG010 - Parameter &2 became initial value when method &1 was called ?

  The SAP error message CMP_MSG010 indicates that a parameter in a method call has become an initial value (i.e., it has been reset to its default state, which is often NULL or an empty value). This typically occurs in the context of ABAP programming when a method is called, and the parameter being passed does not have a valid value.
  Cause:
  
  Parameter Initialization: The parameter might not have been properly initialized before the method call. If the parameter is not assigned a value, it defaults to its initial state.
  Scope Issues: The parameter might be defined in a different scope or context, and its value is not accessible or has been lost when the method is called.
  Data Type Mismatch: If there is a mismatch in the expected data type of the parameter, it may lead to unexpected behavior, including resetting the value.
  Method Logic: The logic within the method itself may inadvertently reset the parameter to its initial value.
  
  Solution:
  
  Check Initialization: Ensure that the parameter is properly initialized before the method call. Assign a valid value to the parameter.
  Review Method Signature: Verify the method signature to ensure that the parameter types match what is expected. Make sure that the parameter is being passed correctly.
  Debugging: Use debugging tools to step through the code and monitor the value of the parameter before and after the method call. This can help identify where the value is being lost.
  Check Method Logic: Review the implementation of the method to ensure that it does not unintentionally reset the parameter. Look for any assignments that might set the parameter to an initial value.
  Use Breakpoints: Set breakpoints in the method to observe the flow of data and see where the parameter might be getting reset.
