Delete columns
As someone with the system administrator security role, you can delete any custom columns that aren’t part of a managed solution. When you delete a column, any data stored in the column is lost. The only way to recover data from a column that was deleted is to restore the database from a point before the column was deleted.
Before you can delete a custom table, you must remove any dependencies that may exist in other solution components.
- In the Solutions area of Power Apps, open the solution that includes the column that you want to delete.
- Open the table, select the Column tab, and then select the column you want to delete.
- Select Show Dependencies on the command bar to view the Dependent components page.
For example, if the column is used in a form or view, you must first remove the column from those solution components.
If you delete a lookup column, the 1:N table relationship for it will automatically be deleted.
