Firstly, it's essential to understand that the method for deleting imported data depends on the type of data you've imported.
- Journals: If you've imported data into journals, the solution is straightforward. You can simply delete the erroneous journal lines directly in the application.
- Master Data (e.g., Customers, Items, Vendors): For master data like customers, the process requires a few more steps. In this case, you can adjust your configuration package and enable the 'Delete before import' option. This allows you to clear out the previously imported data before re-importing the corrected data.
