Hi @Dev_Nikhil ,
Could you please share a bit more about your scenario?
Do you want to know the limits on nested If function in PowerApps app?
Currently, there is no mandatory/known limits on the number of nested If functions in an app within PowerApps. But the amount of the nested If function within an app would affect the app's performance. The more nested If function you added in your app, the lower performance your app would have.
Review the coding standards for maximizing app performance and keeping apps easier to maintain.
More details about the functions supported in PowerApps and its limits, please check the following article:
https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/formula-reference
In addition, the main limit of functions on PowerApps would be the Delegation. Only the delegable functions could delegate the data process to data source (delegable data source) itself, these non-delegable functions could only process data locally.
More details about the Delegation in PowerApps, please check the following article:
Delegation
Best regards,
