• What is the cause and solution for SAP error message FUNC_ADT015 - Parameter &1 declares no type ?

  The SAP error message FUNC_ADT015, which states "Parameter &1 declares no type," typically occurs in the context of ABAP programming when a function module or method is defined with a parameter that does not have an associated data type. This can happen in various scenarios, such as when defining function modules, methods, or even when working with interfaces.
  
  Cause:
  
  Missing Data Type: The parameter in question has been declared without specifying a data type. In ABAP, every parameter must have a defined type (e.g., CHAR, INT, STRING, etc.).
  Typographical Error: There may be a typo in the parameter declaration, leading to the system not recognizing the type.
  Inconsistent Definitions: If the parameter is defined in an interface or a method and the corresponding implementation does not match, it can lead to this error.
  
  
  Solution:
  
  Check Parameter Declaration: Review the function module or method definition and ensure that all parameters have a valid data type specified. For
