• What is the cause and solution for SAP error message /SCMTMS/PLN_VSR_OL420 - Cannot change document &1. Location sequence is fixed ?

  The SAP error message /SCMTMS/PLN_VSR_OL420 indicates that there is an issue with changing a document in the SAP Transportation Management (TM) system because the location sequence is fixed. This typically occurs when you are trying to modify a transportation document (like a shipment or a transportation request) that has a predefined sequence of locations, and the system does not allow changes to that sequence.
  Cause:
  
  Fixed Location Sequence: The location sequence for the transportation document is set as fixed, meaning that it cannot be altered. This is often the case when the document has already been processed or confirmed in some way.
  Document Status: The document may be in a status that does not allow changes. For example, if the document has been released or is in a completed state, modifications may be restricted.
  Configuration Settings: There may be specific configuration settings in the SAP TM system that enforce fixed location sequences for certain types of documents.
  
  Solution:
  
  Check Document Status: Review the status of the document you are trying to change. If it is in a completed or locked state, you may need to reverse or cancel the document before making changes.
  Review Location Sequence: If the location sequence is indeed fixed, you may need to create a new document with the desired changes instead of modifying the existing one.
  Consult Configuration: If you believe the fixed location sequence is not appropriate for your business process, consult with your SAP TM configuration team to see if adjustments can be made to allow for more flexibility in location sequences.
  Use Transaction Codes: Utilize relevant transaction codes (like /SCMTMS/PLN for planning) to check the details of the document and understand why it is locked for changes.
  Documentation and Support: Refer to SAP documentation or reach out to SAP support for further assistance if the issue persists or if you need clarification on specific configurations.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional context.
  User Authorization: Ensure that you have the necessary authorizations to make changes to the document in question.
  Training and Documentation: Familiarize yourself with the SAP TM processes and documentation to better understand how location sequences are managed within the system.
  
  By following these steps, you should be able to address the error message and understand the underlying reasons for the restriction on changing the document.
