The transactions appear during the recording but don't get captured in VSI once the image is created.
All DevTest support versions.
All the transactions might be same and "Allow duplicate Specific Transactions" option is not checked during the recording.
Making attributes as arguments using "Generic XML Payload Parser" DPH made the transactions unique resolved the issue.
Documentation on Generic XML Payload Parser DPH is available at https://docops.ca.com/devtest-solutions/10-1/en/using/using-ca-service-virtualization/using-devtest-workstation-with-ca-service-virtualization/creating-service-images/using-data-protocols/generic-xml-payload-parser-data-protocol
Instead of "Generic XML Payload Parser" DPH, "Request Data Manager" DPH can also be used to make attributes as arguments.
Documentation on "Request Data Manager" DPH is available at https://docops.ca.com/devtest-solutions/10-1/en/using/using-ca-service-virtualization/using-devtest-workstation-with-ca-service-virtualization/creating-service-images/using-data-protocols/request-data-manager-data-protocol.
