Processes (Bots) works bur erase some other values

[anonymous]

Hello,

In my app, i have a bot with a process that enters a date (if the field is empty) when I enter another value in the current row.
The bot works but it deletes values in some columns.
I don’t understand why, can you help me?

A common cause for this is that adding a row with a key column value that is already used by an existing row. The new row replaces the existing row, wiping out all of the existing row’s values and replacing them with the new row’s values. If your intent is to update an existing row, make sure you’re using an action that updates rather than adds rows.

Hello Steve,

I don’t think I’m making that mistake, I’m sharing some screen impressions

In my action, I use the function set a row value.
