How To Fix FUNC_ADT023 - Function modules with global parameters having TYPE ANY cannot be edited

SAP Error Message - Details

• Message type: E = Error

• Message class: FUNC_ADT -

• Message number: 023

• Message text: Function modules with global parameters having TYPE ANY cannot be edited

What causes this issue?

The function module you try to edit has global parameters declared with
empty associated type (or explicit type set to ANY).
ABAP in Eclipse would always set this type to ANY (which is equivalent
at runtime) but in the function group other function modules with same
parameters like the global ones, must have all an identical associated
type.

System Response

The LOCK action is canceled.

How to fix this error?

Edit the function module with transaction SE37 in backend.

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_ADT023 - Function modules with global parameters having TYPE ANY cannot be edited ?

  The SAP error message FUNC_ADT023 indicates that you are trying to edit a function module that has global parameters defined with the type ANY. This restriction is in place because using ANY as a parameter type can lead to ambiguity and potential issues in the function module's behavior, making it difficult to ensure type safety and proper handling of data.
  Cause:
  The primary cause of this error is the presence of global parameters in the function module that are defined with the type ANY. This type is not allowed for editing in the ABAP Development Tools (ADT) environment because it can lead to unpredictable behavior and makes it difficult to maintain the code.
  Solution:
  To resolve this error, you need to change the parameter types from ANY to a more specific type. Here are the steps you can follow:
  
  
  Identify the Function Module: Determine which function module is causing the error.
  
  
  Open the Function Module: Use transaction SE37 or the ABAP Development Tools (ADT) in Eclipse to open the function module.
  
  
  Check Parameter Types: Look at the parameters defined in the function module. Identify any parameters that are defined with the type ANY.
  
  
  Change Parameter Types: Modify the parameter types from ANY to a specific data type that accurately represents the data being passed. For example, if the parameter is intended to be a string, you can change it to STRING or CHAR. If it is a table, you can specify the appropriate table type.
  
  
  Save and Activate: After making the changes, save and activate the function module.
  
  
  Test the Function Module: Ensure that the function module works as expected after the changes.
  
  
  Related Information:
  
  Type Safety: Using specific data types instead of ANY helps maintain type safety, making the code easier to understand and less prone to runtime errors.
  Best Practices: It is generally a best practice to avoid using ANY in function modules and methods. Always define parameters with specific types to ensure clarity and maintainability.
  Documentation: Refer to the SAP documentation for more information on function module parameters and data types.
  
  By following these steps, you should be able to resolve the FUNC_ADT023 error and successfully edit your function module.
