• What is the cause and solution for SAP error message /SCMTMS/SCH158 - Enter an availability time that is not before the arrival time ?

  The SAP error message /SCMTMS/SCH158 indicates that there is an issue with the scheduling of transportation in the SAP Transportation Management (TM) module. Specifically, the error states that the availability time entered is before the arrival time, which is logically incorrect. This typically occurs when you are trying to schedule a transportation event, such as a shipment or a delivery, and the times you have entered do not align correctly.

  Data Entry Error: There may have been a mistake in entering the times, such as a typographical error or misunderstanding of the time format.
  System Configuration: There could be issues with the configuration of the transportation management settings that affect how times are calculated or displayed.
  
  Solution:
  
  Check Time Entries: Review the availability time and arrival time you have entered. Ensure that the availability time is set to a time that is equal to or later than the arrival time.
  Adjust Scheduling: If the availability time is indeed before the arrival time, adjust it to reflect a realistic scenario where goods are available before they are scheduled to arrive.
  Consult Documentation: Refer to the SAP documentation or help resources for guidance on how to properly enter scheduling times in the TM module.
  Test with Different Scenarios: If you are unsure about the correct times, try testing with different scenarios to see how the system responds and what times are accepted.
  Check for System Updates: Ensure that your SAP system is up to date, as there may be patches or updates that address known issues with time handling in the TM module.
