# InputTables username setup
In SuperTables for Power BI, the username for InputTables is chosen in the general InputTables configuration (configuration → InputTables), *not* from the visual’s Format pane. To make a column available for selection, first add it to the visual (either the **Column** or **Value** box in the Format pane). If the username column isn’t added to the visual, InputTables won’t detect it and it won’t appear in the configuration dropdown.
Once you add the column it will appear in the SuperTables grid. Open the **Custom configuration**, go to the InputTables tab, log in, and select the column as the username. After you save the InputTables configuration, the chosen username column will be registered with InputTables and will be removed from the SuperTables grid.
If you don’t already have a username column, you can create one in your semantic model by adding a new measure that uses the `USERNAME()` function — this creates a column containing the current user’s name which you can then add to the visual and select in InputTables.

## 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, and the optional `goal` query parameter:
```
GET https://docs.infotopics.com/supertables/getting-started/powerbi/inputtables-username-setup.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
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.
