Open the 'Transaction date' control and select the date column e.g., 'Return Date'.
'Transaction date' mapping shows the selected column. -

Dates parse using the chosen format.
Troubleshooting
-
Selected dates are incorrect or fail to parse.
LikelyCause: Wrong 'Date format' or wrong column selected.
Action: Re-select the correct 'Transaction date' column and adjust 'Date format' to match the date order in your file. -
