# act\_typ

The actions that can be triggered using the lum.dtl file are defined in the SWAT+ code. For each action, the type and ID of the object it is applied to, and a user-defined name have to be specified. Certain actions require additional information, which has to be specified in the fields option, const, const2, and fp. The use of these four fields depends on the action. The table below lists the actions implemented in the SWAT+ code, a short description, and the additional fields needed.   

| Action           | Description                                 | Additional fields needed                                                                                                                                                                                                                                                 |

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://swatplus.gitbook.io/io-docs/introduction-1/decision-tables/lum.dtl/act_typ.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
