• What is the cause and solution for SAP error message /SCWM/QRFC_TOOLS034 - Nested table parameter(s) &1 &2 &3 exist; these contents are not shown ?

  The SAP error message /SCWM/QRFC_TOOLS034 indicates that there are nested table parameters in the context of a QRFC (Queued Remote Function Call) that are not being displayed due to their existence. This typically occurs in the context of SAP Extended Warehouse Management (EWM) or similar applications that utilize QRFC for asynchronous processing.
  Cause:
  The error is caused by the presence of nested table parameters in the function module or method being called. QRFC has limitations on how it handles nested tables, and as a result, it cannot display or process these nested structures correctly. This can happen when the function module is designed to handle complex data structures that include nested tables.
  Solution:
  To resolve this issue, you can consider the following approaches:
  
  
  Review the Function Module: Check the function module or method that is being called. If it includes nested tables, consider refactoring the code to avoid using nested tables. Instead, use flat structures or separate tables that can be processed independently.
  
  
  Modify the QRFC Call: If you have control over the QRFC call, ensure that you are not passing nested tables. Instead, flatten the data structure before making the QRFC call.
  
  
  Check for Updates: Ensure that your SAP system is up to date with the latest support packages and notes. Sometimes, SAP releases patches that address specific issues related to QRFC and nested tables.
  
  
  Consult SAP Notes: Look for relevant SAP Notes in the SAP Support Portal that might address this specific error message. There may be known issues or recommended solutions provided by SAP.
  
  
  Debugging: If you have access to the development environment, you can debug the function module to identify where the nested tables are being created and how they are being passed to the QRFC. This can help you pinpoint the exact cause of the issue.
  
  
  Contact SAP Support: If the issue persists and you cannot find a solution, consider reaching out to SAP Support for assistance. They can provide guidance based on the specific context of your implementation.
  
  
  Related Information:
  
  QRFC: QRFC is used in SAP to handle asynchronous processing of function calls, allowing for better performance and reliability in distributed systems.
  Nested Tables: In ABAP, nested tables are internal tables that contain other internal tables. They can complicate data handling, especially in remote function calls.
  SAP EWM: Extended Warehouse Management is a comprehensive solution for managing warehouse operations, and it often involves complex data structures.
  
  By addressing the nested table issue and ensuring that your QRFC calls are structured correctly, you should be able to resolve the error message and improve the functionality of your SAP system.
