Update a subitem on Monday.com

:bullseye: What is your goal?

Create sub items under an item, then update subitem columns as updates come in.

:thinking: What is the problem & what have you tried?

When I Item is created and moved to a group I create a list of subitems under that item, like a checklist. I have the item name, Date, User, and Message columns.

I don’t have a problem creating the subitem using the “Create a Subitem” module, but when I go to update I get an error message saying the column doesn’t exist. I use the monday.com module to “get an item” and have the option set to show subitems. I can see the subitem ID and also the column values and ID’s. When I use the module to “update column values of a specific item” I get the error message “This column Id doesn’t exist for the board”. I have tried using the column_ID and also the column_title. Both give me the error “This column ID doesn’t exist for the board”. I can see all of the information from the get an item module.

Am I using the correct module to update?

Hi Steve, the issue is that subitems are on a different board in monday.com.

Even though you can see subitem data with Get an Item (show subitems), the Update column values module is still using the parent board, so monday says the column doesn’t exist.

Fix

Use Update column values of a specific item

Set:

Item ID = subitem ID

Board ID = subitems board ID (not the parent board)

Column ID = subitem column ID

Parent and subitem columns are not shared.

Once you point the update to the subitems board, the error goes away.

Regards, Tony
