How To Fix SY287 - This flush is unnecessary because it transports a queue w/o return value.

SAP Error Message - Details

• Message type: E = Error

• Message class: SY - ABAP/4 system messages

• Message number: 287

• Message text: This flush is unnecessary because it transports a queue w/o return value.

What causes this issue?

You should only flush an automation queue when you definitely need
return values from a CALL METHOD or GET PROPERTY. Flushing a queue that
does not contain any return values is expensive in terms of runtime and
is poor programming style. The system flushes automatically at the end
of the PBO event, so there is no danger that automation calls will not
reach the frontend because a flush is missing. If short dumps occur
when you omit the flush, use the Frontend Automation Trace to find the
error.

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 SY287 - This flush is unnecessary because it transports a queue w/o return value. ?

  The SAP error message SY287, which states "This flush is unnecessary because it transports a queue w/o return value," typically occurs in the context of SAP's transport management system, particularly when dealing with transport requests that involve function modules or methods that do not return a value.
  Cause:
  The error arises when a transport request is trying to flush a queue that does not require a return value. In SAP, certain function calls or methods are expected to return values, and if a transport request is set up to handle such a call but the actual function does not return anything, the system generates this error. This can happen in various scenarios, such as:
  
  Attempting to transport a function module or method that is not designed to return a value.
  Misconfiguration in the transport request or the associated objects.
  
  Solution:
  To resolve the SY287 error, you can take the following steps:
  
  
  Check the Function Module/Method: Verify that the function module or method you are trying to transport is indeed designed to return a value. If it is not supposed to return a value, you may need to adjust your transport request.
  
  
  Review Transport Request: Ensure that the transport request is correctly configured. If the request is trying to flush a queue that does not require a return value, you may need to remove or modify the relevant entries in the transport request.
  
  
  Use Correct Transport Method: If you are using a transport method that is not appropriate for the objects you are trying to transport, consider using a different method that aligns with the requirements of the objects.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to transport management and function modules to understand the expected behavior and configurations.
  
  
  Check for SAP Notes: Sometimes, specific issues are documented in SAP Notes. Check the SAP Support Portal for any relevant notes that might address this error.
  
  
  Contact SAP Support: If the issue persists and you cannot find a resolution, consider reaching out to SAP support for assistance. They can provide more detailed guidance based on your specific system configuration and the context of the error.
  
  
  Related Information:
  
  Transport Management System (TMS): Understanding how TMS works in SAP can help you manage transports more effectively and avoid similar errors in the future.
  Function Modules: Familiarize yourself with how function modules are structured and how they should be configured for transport.
  SAP Community: Engaging with the SAP Community can provide insights from other users who may have encountered similar issues.
  
  By following these steps, you should be able to address the SY287 error and ensure that your transport requests are processed correctly.
