Data merging
This function allows you to combine an input file with a merged file. The combined file can be handled as input merge data.
You can also delete duplicate lines and sort data items in input merge data before data processing. To delete duplicate lines, specify the Merge keys for the field that does not allow duplicate lines. When deleting duplicate lines, you can set Priority keys to specify which records of the duplicate lines to retain as is. When sorting the input merge data, you can sort the input merge data (after duplicate lines are deleted) by a field you specify.
You can set these settings in the Input Settings screen in the Data Processing Settings screen.
