3540559 - Intermittent HTTP 401 Errors During Bulk Bank Account Registration via API in SAP S/4HANA Cloud Public Edition

• During the registration of multiple bank accounts via API integration in SAP S/4HANA Cloud Public Edition, intermittent HTTP 401 login errors are encountered.
• The issue significantly impacts processing time and efficiency, leading to a delay in the registration process.
• The error message associated with this issue is "401 Unauthorized".

SAP S/4HANA Cloud Public Edition

1. Initiate the process of registering multiple bank accounts at once via API integration.
2. Observe the occurrence of intermittent HTTP 401 login errors during the process.

The "401 Unauthorized" error typically occurs when all available system processes are occupied, and there are no additional processes available to handle the requests. The system does not maintain a queue for OData requests, so requests that cannot secure a system process will fail with a "401 Unauthorized" response.

1. Consider sending all requests in a single $batch-request. By doing this, all the requests will utilize the same system process, thereby preventing process overload and reducing the probability of request rejections.
2. Understand the specific scenario being accomplished. As the OData service API_BUSINESS_PARTNER is a synchronous API, it is not ideally suited for mass data processing. For more efficient mass data processing, consider using the business partner SOAP integration.
