  The SAP error message SEPM_BO_COMMON402, which states "Customer cannot be changed in a saved sales order," typically occurs when there is an attempt to modify the customer information in a sales order that has already been saved. This restriction is in place to maintain data integrity and ensure that the sales order reflects the correct customer information as it was originally intended.

  Solution:
  
  Create a New Sales Order: If you need to change the customer, the recommended approach is to create a new sales order with the correct customer information.
  Use Change Functionality: If the sales order is still in a state where it can be modified (e.g., not yet saved), you can change the customer before saving it.
  Consult with Your SAP Administrator: If there is a business need to change the customer on a saved order, consult with your SAP administrator or business process owner. They may have specific procedures or authorizations to handle such cases.
