Hi

If you're using a SaaS environment, it is not possible to modify the base code. So what you can do instead is that you can make use of Events provided by Microsoft.

Create a codeunit for Event subscribers. Check where you want to make changes in the base app, find out which event you can subscribe to, and build your logic

f.e., when you refer to codeunit 80, you will find some of the events like OnBeforePostLines, PostSalesLine, OnAfterPostSalesDoc, etc.

For events in Business central, refer to:

docs.microsoft.com/.../devenv-events-in-al
