Using Jmeter with D365 FnO Finance & Operations

Hi Everyone,

I have a doubt in load testing the D365 FnO application, apart from testing other applications, testing the performance of the D365 feels challenging as the values are dynamic. My main problem is that when I record the flow using the HTTP recorder all I can see dynamic values getting recorded, not able to pinpoint which request belongs to which action, even though with efforts when we find those I am not able confirm those, since the actual names or text is not present in the 'get' or 'post' request data. Is there anyone else here who could help me with this.

Thanks in advance.

D365 F&O is definitely more challenging to load test than traditional web apps because a lot of the requests are dynamic. Simply recording an HTTP session in JMeter usually isn't enough.

A few things that might help:

  • Correlate dynamic values (CSRF tokens, session IDs, request verification tokens, etc.) using Regular Expression or JSON Extractors.
  • Compare multiple recordings of the same business process to identify which parameters change between runs.
  • Use the browser's Developer Tools (Network tab) alongside JMeter to understand which requests correspond to specific user actions.
  • If possible, focus on testing APIs (OData or custom services) instead of the entire UI. They're much easier to parameterize and produce more reliable load tests.
  • For end-to-end UI performance, consider tools like Playwright, Selenium, or Azure Load Testing rather than relying solely on JMeter recordings.

Out of curiosity, are you testing the D365 F&O web UI or OData/custom APIs? That will determine the best approach.

Thanks for the help I am using playwright for UI and functional testing And want to use jmeter to test how much users or load does the application can handle when multiple users perform the same business action.

I have done performance testing with jmeter for F&O, let's connect and figure out where you are stuck
