How To Fix FDT_BRS200 - No generated class present for function &1 at timestamp &2

SAP Error Message - Details

• Message type: E = Error

• Message class: FDT_BRS - BRFplus Business Rule Services

• Message number: 200

• Message text: No generated class present for function &1 at timestamp &2

What causes this issue?

You have tried to execute function &v1&, or to simulate that function in
a remote system. However, the system could not find the ABAP OO class
that should have been generated for the function.
This problem may have one of the following root causes:
You are trying to execute the function in the assigned managed system,
but the function has not been deployed as a service to that system.
The generated code exists, but is signed with a later timestamp compared
to the '&v2&' timestamp that was requested.
The required code has been generated, but cannot be retrieved because of
a system inconsistency.
You are trying to execute the function in the assigned managed system,
but the managed system is not available.

System Response

The function cannot be executed.

How to fix this error?

Depending on the different root causes outlined above, take the
necessary measures to correct the problem. For example, you may pass a
different timestamp to the function call, regenerate the function,
repeat the deployment, or check the RFC destination used to access the
managed system.

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 FDT_BRS200 - No generated class present for function &1 at timestamp &2 ?

  The SAP error message FDT_BRS200 indicates that there is no generated class present for a function module or method that is being called in the context of the SAP Fiori or SAP Gateway framework. This typically occurs when there is a missing or improperly generated class for a specific function module, which can lead to issues in executing the related functionality.
  Cause:
  
  Missing Class Generation: The class that is supposed to be generated for the function module has not been created. This can happen if the function module was not properly activated or if there was an issue during the generation process.
  Transport Issues: If the function module or its associated classes were transported from one system to another (e.g., from development to production), there may have been issues during the transport that prevented the class from being generated.
  Development Environment Issues: Sometimes, issues in the development environment, such as missing dependencies or incorrect configurations, can lead to this error.
  Changes in Function Module: If the function module has been modified but the associated class has not been regenerated, this error can occur.
  
  Solution:
  
  
  Regenerate the Class:
  
  Go to the transaction code SE80 (Object Navigator).
  Navigate to the relevant function module.
  Check if the function module is active. If not, activate it.
  Use the option to regenerate the class associated with the function module. This can often be done by right-clicking on the function module and selecting the appropriate option to generate or regenerate the class.
  
  
  
  Check for Transport Issues:
  
  If the function module was transported, ensure that all related objects were included in the transport request.
  Check the transport logs for any errors or warnings that might indicate issues during the transport process.
  
  
  
  Check Dependencies:
  
  Ensure that all dependencies for the function module are met. This includes checking for any required data elements, structures, or other function modules that may be needed.
  
  
  
  Debugging:
  
  If the issue persists, consider debugging the application to identify where the call to the function module is failing and gather more context about the error.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to the specific function module or class to see if there are any known issues or additional steps required for setup.
  
  
  
  Contact SAP Support:
  
  If you are unable to resolve the issue, consider reaching out to SAP support for assistance, especially if this is a production issue.
