【sap public cloud】BUSINESS_PARTNER POST ERROR

masayoshi_tanaka — Tue, 08 Jul 2025 04:52:21 GMT

Nice to meet you.

I am trying to add supplier master data to "BusinessPartner" in "SAP S/4HANA Public Cloud" using tRestClient in "Talend8 Cloud".

The JSON format data to be passed to tRestClient can be registered successfully in POSTMAN, but the following error occurs in Talend. It would be appreciated if you could tell me what the cause is.

Error while parsing an XML stream: 'BOM / charset detection failed'.

はじめまして

「Talend8 cloud」で「sap s/4hana public cloud」の「API_BUSINESS_PARTNER」へtRestclientを使い、サプライヤマスタの追加を試しています。

tRestclientへ渡すJSON形式のデータは、POSTMANでは正常に登録可能なのですが、Talendだと以下のエラーが発生しております。何が原因かご教示頂けると助かります。

Hello,

Thank you very much for your question.

Can you please check whether the following information solves your error?

Possible Causes and Solutions for the Error

The error message ‘Error while parsing an XML stream: BOM / charset detection failed’ suggests that there might be an issue with the character encoding or the presence of a Byte Order Mark (BOM) in the data being sent from Talend to the SAP S/4HANA Cloud API.

Causes:

Character Encoding:
- The data might be encoded in a format that is not expected by the API, such as UTF-16 instead of UTF-8.
Byte Order Mark (BOM):
- A BOM might be present at the beginning of the JSON data, which can cause issues during parsing.

Solutions:

Check Encoding Settings:
- Ensure that the JSON data is encoded in UTF-8, which is typically expected by APIs.
Remove BOM:
- If a BOM is present, remove it from the JSON data before sending it to the API.
Validate JSON Format:
- Double-check the JSON format to ensure it is correctly structured and matches the expected payload format for the API.
Use Postman as a Reference:
- Since the data works in Postman, compare the headers and body format used in Postman with those in Talend to identify any discrepancies.

Additional Tips

Debugging: Use logging or debugging tools in Talend to inspect the exact payload being sent and ensure it matches the successful request made in Postman.
Consult Documentation: Refer to the SAP API documentation for any specific requirements regarding data format and encoding.

By addressing these potential issues, you should be able to resolve the error and successfully add supplier master data using Talend.

Kind regards,

Henrike
