The extensibility applied to the ERP engines' events can be run either by the ERP or by external applications, with the goal of applying **the same rule to all documents**, whether internal to the ERP or external, such as PAA.

This means you can use the ERP's extensibility when documents are **saved from PAA**, for example, when the **BeforeSave and AfterSave** events are triggered when saving documents in the Accounting Postings Editor.

For the ERP's extensibilities to be loaded, you must create the **environment.config** file in PAA's installation folder, with specific content ([see content](https://helpcenter.ila.cegid.com/wp-content/uploads/PAA-intalacao-environmentconfig-extensibilidade.txt)).
