*Note : For your information the above selected schema is actually defining the structure of your BI Report Response. If you want to get the structure of your BI Report Response then just decode the base64 output data (just google base64 decode tool and then paste the base64 output to decode) and after that you can see the XML format. Using this xml you can create the schema file.

Base64 decode Tool

• Stage Read operation configuration completed , click Done.

• Save the integration and close the window. Activate the integration and submit it to test it.

• Once integration processed successfully, open the monitoring window and check the stage Read Response. You can the see the Report Response in proper readable XML Format. Now you can use these data for further processing in the integration flow.

Thank You !we have successfully developed the integration to invoke BI Report in an integration. If you have any questions please do let me know in comment section.
