Break point is not sticking in odata while running fiori app

Hai Experts,

I am developing one custom application in SAPUI5 and using the odata services to access the backend, due to check one scenario kept one external debugger in the odata for the same client and same user, but after triggering from fiori its not sticking in the odata and immediatly getting the response, tried many times. but no luck.

Can anybody suggest what will be the issue here to stick the break point.

Thanks,

Muhsin
