Troubleshooting
Problem
User clicks "Transfer - External Data - Import from Flat Files":
User chooses import specification, and CSV/TXT file. User clicks 'import/run' button.
- An error appears.
Example:
In one real-life example:
- The import specification was working previously in earlier month. Issue started suddenly one day.
- Import data seems to fail after certain number of rows imported.
- It is not related to invalid data as same rows (not imported in a previous attempt) can successfully be imported by reducing the number of rows (in the CSV/TXT file).
