• What is the cause and solution for SAP error message /SCMTMS/SCH178 - Enter a source location that is before the destination location ?

  The SAP error message /SCMTMS/SCH178 indicates that there is an issue with the scheduling of transportation in the SAP Transportation Management (TM) module. Specifically, the error states that the source location (where the goods are being shipped from) is set to a point that is chronologically before the destination location (where the goods are being shipped to). This typically means that the system is unable to create a valid transportation schedule because the source location cannot logically precede the destination location in time.
  Cause:
  
  Incorrect Date/Time Settings: The dates or times assigned to the source and destination locations may be incorrectly configured, leading to the source being set to an earlier time than the destination.
  Data Entry Error: There may have been a manual error in entering the source or destination dates/times.
  Master Data Issues: The master data for the locations may not be correctly set up, leading to inconsistencies in the scheduling.
  Transportation Lane Configuration: The transportation lanes may not be configured correctly, causing the system to misinterpret the sequence of locations.
  
  Solution:
  
  Check Dates and Times: Review the dates and times assigned to both the source and destination locations. Ensure that the source location's date/time is set to a time that is before the destination location's date/time.
  Correct Data Entry: If there was a manual entry error, correct the source or destination information in the relevant transaction or document.
  Review Master Data: Ensure that the master data for the locations is accurate and up-to-date. This includes checking the time zones and any other relevant settings.
  Adjust Transportation Lane: If the issue is related to transportation lane configuration, review and adjust the settings in the transportation lane to ensure they reflect the correct sequence and timing.
  Consult Documentation: Refer to SAP documentation or help resources for additional guidance on scheduling and transportation management.
