Delete caches in Dynamics 365 F&O

In Dynamics 365 Finance and Operations (D365 F&O), clearing the Application Object Tree (AOT) cache usually involves running specific utility functions through the user interface or a URL, or performing actions in a development environment. There is no single "Clear AOT Cache" button in the standard UI. 

From the User Interface (Functional Users/Admins)

You can clear various server-side caches, including those related to AOT elements and extensions, using a specific page in the application. 

1. Navigate to the utility page by modifying your D365 F&O URL. Append 

·       mi=sysclassrunner&cls=sysflushaod

·       mi=sysclassrunner&cls=sysflushdata

·       mi=sysclassrunner&cls=sysflushdictionary

to your base D365 F&O URL.

• Example: https://[yourD365URL]/?cmp=USMF&mi=sysclassrunner&cls=SysFlushAod

2. Alternative UI Method (if TMS is enabled): Navigate to Transportation management > Setup > Load building > Load building strategies and click the Generate class list button. This action internally calls SysFlushAod::main() and flushes several caches. 

In a Development Environment (Developers)

In a development environment (Dev VM), a full build and synchronization of the related model is the standard way to ensure AOT changes are reflected, which implicitly handles caching issues related to code changes. 

• Build and Synchronize: In Visual Studio, after making changes, right-click your project or model in the Application Explorer and select Build and then Synchronize database.
• Clear Visual Studio Cache: Sometimes, Visual Studio itself caches data. You can delete the files in the ComponentModelCache folder at: C:\Users\[YourUser]\AppData\Local\Microsoft\VisualStudio\[Version]\ComponentModelCache
