• What is the cause and solution for SAP error message RU401 - There are no subsystem confirmations ?

  The SAP error message RU401 ("There are no subsystem confirmations") typically occurs in the context of production planning and control, particularly when dealing with confirmations in the production process. This error indicates that the system is unable to find any confirmations for a particular production order or operation in the relevant subsystem.
  Causes:
  
  No Confirmations Entered: The most straightforward cause is that no confirmations have been entered for the production order or operation in question.
  Incorrect Order Status: The production order may not be in a status that allows for confirmations to be processed.
  Missing Subsystem Integration: If the system is integrated with other subsystems (like MES or other production systems), there may be issues with the integration that prevent confirmations from being recorded.
