• What is the cause and solution for SAP error message ECATT_ODATA_TST137 - HTTP header in batch section does not contain a "Content-Length". ?

  The SAP error message ECATT_ODATA_TST137 indicates that there is an issue with the HTTP header in the batch section of an OData request. Specifically, it states that the "Content-Length" header is missing. This can lead to problems when the server tries to process the batch request, as it relies on the "Content-Length" header to determine the size of the incoming data.
  Cause:
  
  Missing Content-Length Header: The HTTP request is missing the "Content-Length" header, which is required for the server to understand how much data is being sent in the request.
  Incorrect Configuration: The configuration of the eCATT (extended Computer Aided Test Tool) or the OData service might not be set up correctly, leading to the omission of this header.
  Batch Processing Issues: If the request is being sent as a batch, the way the batch is constructed might not be compliant with the OData protocol, which requires specific headers to be present.
  
  Solution:
  
  Add Content-Length Header: Ensure that the HTTP request includes the "Content-Length" header. This can often be done by modifying the eCATT script or the configuration of the OData service to include this header.
  Check eCATT Configuration: Review the eCATT configuration to ensure that it is set up correctly for OData services. Make sure that the batch requests are being constructed properly.
  Update OData Service: If you have control over the OData service, ensure that it is capable of handling batch requests correctly and that it is configured to expect the "Content-Length" header.
  Test with a Different Tool: If possible, test the OData service using a different tool (like Postman or curl) to see if the issue persists. This can help determine if the problem is with the eCATT configuration or the OData service itself.
  
  Related Information:
  
  OData Protocol: Familiarize yourself with the OData protocol specifications, particularly regarding batch processing and the required headers.
  SAP Notes: Check SAP Notes for any known issues or patches related to eCATT and OData services.
  Debugging: Use debugging tools to inspect the HTTP request being sent to the server. This can help identify if the "Content-Length" header is indeed missing and assist in troubleshooting.
  SAP Community: Engage with the SAP Community forums for additional insights or similar issues faced by other users.
  
  By addressing the missing "Content-Length" header and ensuring proper configuration, you should be able to resolve the ECATT_ODATA_TST137 error.
