Smart SAP Assistant

• What is the cause and solution for SAP error message ID640 - &1 is assigned to several work items; only one was started. ?

  The SAP error message ID640 indicates that a particular work item is assigned to multiple instances, but only one of those instances can be processed at a time. This typically occurs in scenarios where a work item is linked to multiple tasks or processes, and the system is designed to prevent concurrent processing of the same work item to avoid conflicts or data inconsistencies.
  Cause:
  
  Multiple Assignments: The work item in question is assigned to several users or tasks, leading to confusion about which instance should be processed.
  Workflow Configuration: The workflow may be incorrectly configured, allowing the same work item to be assigned to multiple paths or users.
  Locking Mechanism: SAP uses a locking mechanism to ensure that only one user can process a work item at a time. If multiple users attempt to start the same work item, this error will occur.
  
  Solution:
  
  Identify the Work Item: Determine which work item is causing the error. You can do this by checking the work item ID mentioned in the error message.
  Check Assignments: Review the assignments of the work item to see if it is indeed assigned to multiple users or tasks. You can do this through transaction codes like SWI1 (Work Item Selection) or SWI2_FREQ (Work Item Overview).
  Reassign Work Items: If necessary, reassign the work item to a single user or task to ensure that it can be processed without conflict.
  Workflow Configuration: If the issue is due to workflow configuration, consult with your SAP workflow administrator to review and correct the workflow design. Ensure that work items are not duplicated across multiple paths.
  User Communication: Inform users about the status of the work item and advise them to wait until the current processing is complete before attempting to start the work item again.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SWI1, SWI2, and SWI6 for monitoring and managing work items.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP frequently updates its knowledge base with solutions for common problems.
  Documentation: Review SAP documentation on workflows and work item management to better understand how to configure and troubleshoot work items effectively.
  
  If the problem persists after following these steps, it may be beneficial to consult with your SAP support team or refer to SAP's official support channels for further assistance.
