How To Fix FUNC_ADT015 - Parameter &1 declares no type

SAP Error Message - Details

• Message type: E = Error

• Message class: FUNC_ADT -

• Message number: 015

• Message text: Parameter &1 declares no type

What causes this issue?

There is no type declared for parameter &V1&. In the function module's
source-based signature each parameter must declare a type.

System Response

The operation executed on the function module cannot be executed.

How to fix this error?

Declare a type for parameter &V1&.
If you would like to use a non-typed parameter, you can use "
<parameter name> TYPE ANY" for IMPORTING-, EXPORTING and CHANGING
parameters or "<parameter name> TYPE STANDARD TABLE" for TABLES
parameters.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• 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 example:
  FUNCTION my_function.
    IMPORTING
      VALUE(param1) TYPE string.  " Ensure type is specified
  ENDFUNCTION.
  
  Correct Typographical Errors: Look for any typos in the parameter declaration and correct them.
  Consistency in Definitions: If the parameter is part of an interface, ensure that the implementation of the method matches the interface definition in terms of parameter types.
  Use Data Dictionary Types: If applicable, consider using data dictionary types (like structures or tables) to ensure consistency and clarity in your parameter definitions.
  
  Related Information:
  
  ABAP Documentation: Refer to the official SAP ABAP documentation for guidelines on defining function modules and methods.
  SAP Community: Engage with the SAP Community forums for discussions and solutions related to similar issues.
  Debugging Tools: Utilize the ABAP debugger to trace the execution and identify where the parameter is being incorrectly defined or used.
  
  By ensuring that all parameters are correctly defined with appropriate types, you can resolve the FUNC_ADT015 error and prevent it from occurring in the future.
