WZ381 - Details

• SAP Error Message:
  WZ381 Sending failed for work item &1: Pipe could not be closed
  
  Cause
  This error typically occurs in SAP Workflow when the system tries to send a work item (e.g., a workflow task or notification) but fails due to an issue with the communication pipe used internally for data transfer. The message "Pipe could not be closed" indicates that the underlying communication channel (pipe) between processes or system components could not be properly closed after the data transfer.
  Common causes include:
  
  System resource issues: Insufficient system resources (memory, buffer space) causing pipe operations to fail.
  Operating system or kernel-level problems: Problems with the OS pipe handling or inter-process communication.
  Network or RFC communication issues: If the workflow involves remote function calls or communication between different SAP systems, network interruptions or RFC errors can cause pipe closure failures.
  Incorrect or corrupted workflow configuration: Misconfiguration or corrupted workflow objects or container elements.
  Authorization or security restrictions: Insufficient authorizations
