Check a table's dependants

Everything that uses a table is listed on one tab of its popup: Dependant in a Lake table's popup, Dependants in a static table's. Check the list before you change, drop or delete a table, so you know what your change can affect.

Read the list

Open the table's popup and switch to the tab; see Configure a table for the popup itself.

The tab groups objects by kind, in a fixed order: Dimension, Fact, Dictionary, Static, View, Transformation, Lake, Mind, WriteBack, Reference, Presentation and SemanticModel. Only the kinds that are in use appear.
Each group shows a count of the entries it holds, and the groups lay out in one to four columns, depending on the width of the window.
A row shows the object's name. A reference row adds the referencing column in brackets; a presentation row adds where in the deck the table is read, such as slide 4 or slides 4, 7.

For what each kind can be, see Dependants: what uses a table.

Open a dependant

Click a row to open the object it points to. A pencil button appears on a row you can open; its tooltip names the action for that kind:

Kind	Pencil tooltip
Dimension	Edit dimension
Fact	Edit fact
Dictionary	Edit dictionary
Static	Edit static
View	Edit view
Transformation	Edit transformation
Lake	Edit lake
Mind	Start new chat
WriteBack	Edit write-back
Reference	Edit reference
Presentation	Open presentation
SemanticModel	Open semantic model

On a Mind row:

Clicking the row opens the Mind on its Sources; if you cannot open the Mind's settings, the row starts a chat instead.
The pencil starts a new chat with the Mind, and reads Start new chat.
A gear button (tooltip View mind sources) also opens the Mind's Sources.

Not every row opens:

Rows that stand for dependants you cannot access show a count instead of a name and are never clickable.
A Lake row carries no edit action, so nothing opens from it.

When the check finds nothing or fails

What you see	What it means	What to do
Static Not Created with Please save the static table first to view its dependants	A static table's tab, before the table is saved.	Save the table first.
No dependants found with This table is not currently used by any downstream objects.	The check ran and found nothing that uses the table.	Nothing; the table is not in use.
Failed to load dependants with Retry	The list could not load; the reason appears below the heading.	Click Retry; if it keeps failing, see Lake troubleshooting.
Dependants could not be determined	Part of the check failed, so the list can be missing objects. The notice reads "DataPrism dependants could not be determined because the check failed. Acting on the assumption that this table is unused may be unsafe."	Treat the list as incomplete and check the tab again later.

A check that fails never shows No dependants found: a failure has its own message or notice. For a static table, the empty text reads This static table is not currently used by any downstream objects.

Why check before you change or delete a table

The objects in the list keep reading the table. They can break when the table changes, is dropped or is deleted, until you fix them or redeploy the table.
Review the list before a change that drops and recreates a deployed table (see Deploy a table) and before Drop or Delete on the Settings tab (see Run, stop and troubleshoot loads). The removal checks themselves are on What uses a table.

Questions, answered

Which tab is it: Dependant or Dependants?

Both. A Lake table's popup spells the tab Dependant; a static table's popup spells it Dependants. It is the same list of what uses the table in both.

What do the counts next to a group show?

They count the entries in that group for the current check. The groups themselves always keep the same order.

Where does clicking a row take me?

To the object the row names: a table, a transformation, a write-back, a deck, a semantic model, or a Mind. A reference row opens the table it points to, and a Mind row opens the Mind's Sources (or a chat, if you cannot open the Mind's settings).

What does the pencil on a Mind row do?

It starts a new chat with the Mind; its tooltip reads Start new chat. To open the Mind's Sources instead, use the gear button with the tooltip View mind sources.

Why does a row show a column or a slide in brackets?

A reference row adds the referencing column in brackets, and a presentation row adds where in the deck the table is read, such as slide 4 or slides 4, 7.

Why can't I click some rows?

Rows that stand for dependants you cannot access show a count instead of a name and are never clickable. A Lake row carries no edit action, so nothing opens from it. Every other row can be opened.

What does the "Dependants could not be determined" notice mean?

Part of the check failed, so the list can be missing objects. It never means the table is unused: treat the list as incomplete and check the tab again later.

The tab says "Failed to load dependants". What do I do?

Click Retry to run the check again. If it keeps failing, see Lake troubleshooting.

Why does a static table's tab say "Static Not Created"?

The static table has not been saved yet, so there is nothing to check: Please save the static table first to view its dependants. Save the table and open the tab again.
