AppSheet deployment error: INCORRECTCOLUMNNAMES after regenerating structure

AppSheet AppSheet Q&A
1

Hello,

I am building an AppSheet app using an AppSheet Database. I have encountered a persistent error during the deployment check.

Error message:

Table '일별출근현황' has been assigned a data source with incorrect column names. 사업단 ID does not match 출근 인원.

Error code: ERROR APPDEF INCORRECTCOLUMNNAMES

What I have already tried:

  1. Checked the original AppSheet Database table and confirmed that both columns exist.

  2. Confirmed that 사업단 ID is a Ref column and 출근 인원 is a Number column.

  3. Compared the column order in the database and AppSheet editor.

  4. Used Regenerate Structure for the affected table.

  5. Saved the app and ran a new deployment check.

Unfortunately, the same error persists.

The app currently works in prototype mode. Attendance records can be viewed, and PDF reports are generated correctly.

My question:

How can I resolve this column structure mismatch without deleting existing records, recreating the table, or breaking the current app functionality?

Any guidance would be greatly appreciated.

Thank you.
