Smart SAP Assistant

• What is the cause and solution for SAP error message ECATT_ODATA_TST136 - HTTP header in batch section does not contain a "Content-Type". ?

  The SAP error message ECATT_ODATA_TST136 indicates that an HTTP request made during an eCATT (extended Computer Aided Test Tool) execution is missing the "Content-Type" header in the batch section. This header is crucial for the server to understand the format of the data being sent in the request.
  Cause:
  The absence of the "Content-Type" header typically occurs due to one of the following reasons:
  
  Incorrect Configuration: The eCATT script or configuration may not be set up correctly to include the necessary headers.
  Batch Request Format: When sending batch requests to an OData service, each part of the batch must specify its content type. If this is not done, the server cannot process the request correctly.
  Missing or Incorrect eCATT Commands: The commands used in the eCATT script may not be properly defined to include the required headers.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check eCATT Script:
  
  Review the eCATT script to ensure that it includes the "Content-Type" header in the batch request. The header should specify the type of content being sent (e.g., application/json or application/xml).
  
  
  
  Modify Batch Request:
  
  
  If you are constructing a batch request manually, ensure that each part of the batch request includes the "Content-Type" header. For example:
  --batch_1
  Content-Type: application/http
  Content-Transfer-Encoding: binary
  
  POST /service/path HTTP/1.1
  Content-Type: application/json
  ...
  
  
  
  
  Use Correct eCATT Commands:
  
  Ensure that you are using the correct eCATT commands that automatically handle the inclusion of headers. If you are using custom commands, you may need to modify them to include the necessary headers.
  
  
  
  Test with a Simple Request:
  
  As a troubleshooting step, try sending a simple request to the OData service without batching to see if the issue persists. This can help isolate whether the problem is with the batch processing or the service itself.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for eCATT and OData services to ensure that you are following the correct procedures for setting up batch requests.
  
  
  
  Check SAP Notes:
  
  Look for any relevant SAP Notes or updates that may address this specific issue or provide additional guidance.
  
  
  
  Related Information:
  
  OData Protocol: OData (Open Data Protocol) is a standard protocol for building and consuming RESTful APIs. Understanding how OData handles requests and responses can help in troubleshooting issues related to HTTP headers.
  eCATT Documentation: Familiarize yourself with the eCATT documentation to understand how to properly configure and execute tests, especially when dealing with OData services.
  HTTP Headers: Understanding the role of HTTP headers, including "Content-Type", can help in diagnosing similar issues in the future.
  
  By following these steps, you should be able to resolve the ECATT_ODATA_TST136 error and successfully execute your eCATT tests.
