  Error Message: WG204 - An unprocessed document already exists
  
  
  Cause:
  This error occurs in SAP Workflow when you try to create or trigger a workflow task or workflow container that is linked to a document (such as a purchase order, invoice, or any business object), but there is already an existing workflow task or workflow instance related to the same document that has not yet been processed or completed.
  In other words, the system prevents the creation of duplicate or parallel workflow tasks for the same document to avoid conflicts or redundant processing.
  Typical scenarios include:
  
  A workflow is triggered multiple times for the same document before the previous workflow instance is completed.
  A workflow task is still open or in process for the document.
  The workflow container or binding is not cleared or reset properly after the previous workflow run.
