• What is the cause and solution for SAP error message /SCMTMS/VSS_ENGINE036 - Un-/loading of document &2 with maximum durations can't be scheduled ?

  The SAP error message /SCMTMS/VSS_ENGINE036 indicates that the system is unable to schedule the un/loading of a document due to maximum duration constraints. This typically occurs in the context of transportation management within SAP, where the system is trying to plan or schedule the loading or unloading of goods but encounters issues related to time constraints.
  Cause:
  
  
  Maximum Duration Exceeded: The error usually arises when the planned loading or unloading duration exceeds the maximum allowed duration defined in the system settings. This can happen if:
  
  The loading/unloading times are set too high in the configuration.
  The transportation planning does not account for the actual time required for loading/unloading.
  There are constraints in the transportation network that affect scheduling.
  
  
  
  Configuration Issues: There may be incorrect or missing configuration settings in the transportation management module, such as:
  
  Maximum loading/unloading durations not being set correctly.
  Incomplete master data for the transportation lanes or resources.
  
  
  
  Resource Availability: The resources (e.g., vehicles, loading docks) may not be available for the required duration, leading to scheduling conflicts.
  
  
  Solution:
  
  
  Check Maximum Duration Settings: Review the maximum loading/unloading duration settings in the configuration. You can do this by navigating to the relevant customizing settings in SPRO:
  
  SPRO > Logistics Execution > Transportation > Basic Transportation Functions > Define Maximum Loading/Unloading Durations.
  Adjust the maximum durations as necessary to accommodate the planned activities.
  
  
  
  Review Transportation Planning: Analyze the transportation planning process to ensure that the planned durations for loading/unloading are realistic and align with the defined maximum durations.
  
  
  Resource Management: Ensure that the resources required for loading/unloading are available and that their availability is correctly reflected in the system.
  
  
  Check Master Data: Verify that all relevant master data (e.g., transportation lanes, shipping points, and resources) is correctly maintained and up to date.
  
  
  Adjust Planning Parameters: If necessary, adjust the planning parameters or constraints in the transportation management system to allow for more flexibility in scheduling.
  
  
  Related Information:
  
  Transaction Codes: You may want to use transaction codes like /SCMTMS/PLANNING to analyze the planning process or /SCMTMS/VSS for specific transportation management functions.
  SAP Notes: Check for any relevant SAP Notes that may address known issues or provide additional guidance on this error message.
  Documentation: Refer to the SAP Help Portal for detailed documentation on transportation management and scheduling.
