RE: Safely removing unused columns identified via dependency checks in Appian

You’re already doing the right kind of due diligence—but I wouldn’t call it “safe enough to delete” just yet. In Appian, unused-looking columns can still bite you later because usage isn’t always obvious or directly referenced.

Appian has indirect usage patterns that won’t show up clearly in these checks: like Process variables (PV mappings),Script tasks / expressions, Smart services (Write to Data Store, integrations).

if Appian doesn’t use the field internally, External systems might expect it, APIs might still send/receive it so you can check the following objects: Integration objects, Web APIs, Connected systems

Sometimes fields are dynamically referenced (fv!item[fieldName])

Database-level dependencies: Check in DB Views using the column, Stored procedures,Triggers

So on a high note instead of deleting it Rename column from fieldname to fieldname_DEPRECATED and verify if its working or breaking the logic

I think your approach is valid. Just make sure there is no dependency. To validate this, you could rename the columns and check whether the application keeps working. Then, delete them after validation.
