• What is the cause and solution for SAP error message VN091 - The starting time for output & must be before the end time ?

  SAP Error Message:
  
  VN091 – The starting time for output & must be before the end time
  
  Cause:
  This error occurs when the system detects that the start time specified for an output (such as a print output, message output, or communication output) is not earlier than the end time. In other words, the time interval defined for the output processing is invalid because the start time is equal to or later than the end time.
  This typically happens in scenarios involving scheduling or timing parameters for output determination, for example:
  
  When defining output conditions or output control parameters.
  When setting time intervals for message output or print jobs.
  When configuring partner profiles or output device scheduling.
  
  
  Solution:
  
  
  Check the Time Interval:
  
  Go to the relevant configuration or transaction where the output timing is maintained.
  Verify the start time and end time fields.
  Ensure that the start time is strictly earlier than the end time.
  
  
  
  Correct the Time Entries:
  
  If the start time is equal to or after the end time, adjust the times so that the start time precedes the end time.
  For example, if start time is 15:00 and end time is 14:00, change the end time to a time after 15:00 or adjust the start time accordingly.
  
  
  
  Save and Test:
  
  After correcting the times, save the changes.
  Re-run the output or process to confirm that the error no longer occurs.
  
  
  
  
  Related Information:
  
  This message is part of the output control and scheduling logic in SAP.
  It can appear in various modules where output timing is relevant, such as MM (Purchasing), SD (Sales and Distribution), or FI (Financial Accounting).
  The message text uses a placeholder & which will be replaced by the specific output type or parameter name in the actual message.
  If you encounter this error during partner profile configuration (transaction WE20) or output determination (transaction NACE), check the time intervals defined for message output.
  
  
  Example Scenario:
  In transaction NACE (Output Types), when defining the output timing for a message, you might specify:
  
  Start time: 10:00
  End time: 09:00
  
  This will trigger VN091 because the start time is not before the end time.
