We have added two new error codes to improve the handling of concurrent modifications for Standalone Prices. These error codes provide detailed information about which specific price scope fields are currently locked during modifications, helping you implement better retry logic and conflict resolution in your applications.
When multiple modifications are attempted simultaneously on Standalone Prices with overlapping scope fields (such as SKU, currency, country, Customer Group, Channel, validity period, or Recurrence Policy), the API now returns specific 409 Conflict errors:

Both errors include detailed information about the locked price scope. This allows you to identify the exact conflicting operation before you retry your request.
