• What is the cause and solution for SAP error message SADT_REST101 - Expected batch part boundary: &2 in message body not found (Line: &1) ?

  The SAP error message SADT_REST101 indicates that there is an issue with the expected batch part boundary in a message body when working with RESTful services in SAP. This error typically occurs when the system is expecting a specific format in the incoming request, particularly when dealing with multipart requests.
  Cause:
  The error message "Expected batch part boundary: &2 in message body not found (Line: &1)" suggests that the system is unable to find the expected boundary delimiter in the multipart message. This can happen due to several reasons:
  
  
  Incorrect Content-Type Header: The Content-Type header in the HTTP request may not be set correctly. For multipart requests, it should be something like multipart/mixed; boundary=your_boundary.
  
  
  Malformed Request Body: The body of the request may not be formatted correctly according to the multipart specification. This includes missing boundaries or incorrect line endings.
  
  
  Network Issues: Sometimes, network issues can lead to incomplete data being sent, which can cause the boundary to be missing.
  
  
  Client-Side Issues: The client sending the request may not be constructing the multipart request correctly.
  
  
  Solution:
  To resolve the SADT_REST101 error, you can take the following steps:
  
  
  Check the Content-Type Header: Ensure that the Content-Type header is set correctly in your HTTP request. It should specify the correct boundary.
  Example:
  Content-Type: multipart/mixed; boundary=your_boundary
  
  
  Validate the Request Body: Review the body of the request to ensure that it adheres to the multipart format. Each part should start with the boundary and end with the boundary followed by two hyphens (--).
  Example of a correctly formatted multipart request:
  --your_boundary
  Content-Disposition: form-data; name="part1"
  
  Content of part 1
  --your_boundary
  Content-Disposition: form-data; name="part2"
  
  Content of part 2
  --your_boundary--
  
  
  Use a Tool for Testing: Use tools like Postman or cURL to test your API calls. These tools can help you format your requests correctly and see the raw request and response.
  
  
  Check for Network Issues: Ensure that there are no network issues that could be causing data to be truncated or lost.
  
  
  Review Client Code: If you are using a custom client to send requests, review the code to ensure that it constructs the multipart request correctly.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific API you are working with to ensure that you are following the expected request format.
  
  
  Related Information:
  
  SAP API Documentation: Always refer to the official SAP API documentation for the specific service you are using to understand the expected request format and parameters.
  Debugging Tools: Use debugging tools available in SAP to trace the request and response to identify where the issue might be occurring.
  Community Forums: If the issue persists, consider reaching out to SAP community forums or support for additional assistance.
  
  By following these steps, you should be able to identify and resolve the cause of the SADT_REST101 error.
