  The SAP error message "ERP_PURCH_VENDOR_API008 Change vendor &1 failed because the API doesn't run in change mode" typically occurs when there is an attempt to modify vendor data using an API that is not configured to handle changes. This can happen in various scenarios, such as when using the wrong function module or when the API is not set up to allow changes to the vendor data.
  Cause:
  
  Incorrect API Mode: The API being called is not in change mode. Some APIs are designed only for read operations and do not support updates or changes.
  Configuration Issues: The API might not be properly configured to allow changes to vendor data.
  Data Locking: The vendor record might be locked by another process, preventing changes from being made.

  Solution:
  
  Check API Documentation: Review the API documentation to ensure that you are using the correct API for changing vendor data. Make sure that the API supports change operations.

  Check for Locks: Use transaction codes like SM12 to check if the vendor record is locked by another user or process. If it is locked, you may need to wait until the lock is released.
  Review Authorizations: Ensure that the user executing the API call has the necessary authorizations to change vendor data. This may involve checking roles and authorizations in transaction PFCG.
  Debugging: If you have access to the development environment, consider debugging the API call to identify where the failure occurs and to gather more information about the error.
