• Message text: Duplicate delayed request for method &1 not supported

What causes this issue?

If you perform a delayed request by specifying 'X' for the parameter
IV_DELAYED when calling IF_CLB_PROCESS->EXECUTE you can do this just
once per method before you perform the IF_CLB_PROCESS->SYNCHRONIZE call.
In the current case a second call to IF_CLB_PROCESS-EXECUTE has happened
before IF_CLB_PROCESS->SYNCHRONIZE has been called.

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 CLB502 - Duplicate delayed request for method &1 not supported ?

  The SAP error message CLB502 indicates that there is a duplicate delayed request for a method that is not supported. This typically occurs in the context of SAP's Business Workflow or when using the Business Object Processing Framework (BOPF) where methods are being called in a way that the system does not allow for duplicates.
  Cause:
  
  Duplicate Requests: The error is often caused by an attempt to process the same request multiple times, which the system does not support. This can happen if a method is triggered multiple times in quick succession.
  Incorrect Configuration: There may be a configuration issue in the workflow or business object that leads to the same method being called redundantly.
  Concurrency Issues: If multiple users or processes are trying to execute the same method at the same time, it can lead to this error.
  
  Solution:
  
  Check for Duplicates: Review the code or workflow configuration to ensure that the method is not being called multiple times unnecessarily. Implement checks to prevent duplicate calls.
  Adjust Workflow Logic: If the error is occurring in a workflow, consider adjusting the workflow logic to handle the method calls more effectively, ensuring that they are not triggered simultaneously.
  Error Handling: Implement error handling in your code to catch this specific error and manage it gracefully, possibly by logging it or notifying the user.
  Review BOPF Configuration: If you are using BOPF, check the configuration of the business object and its methods to ensure they are set up correctly and that there are no conflicting settings.
  Consult SAP Notes: Look for any relevant SAP Notes that may address this specific error or provide patches or updates that could resolve the issue.
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for Business Workflow and BOPF for more details on method handling and error management.
