Error while defining oData model

Hi  all,

Having a problem while defining odata model.

This is my code 

while debuggingi got an error as below 

XMLHttpRequest cannot load

https://tamc.transaltus.com:5200/sap/opu/odata/sap/ZEJF_DATAPROVIDER_SRV/$metadata.

No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://webidetestingempform-p1941389882trial.dispatcher.hanatrial.ondemand.com' is therefore not allowed access. The response had HTTP status code 401.

Please help me on this.

Thanks

Damian
