Field help (AHISTOTRDE) 

If this check box is ticked, it causes the writing, of the operation log, of a list of each line purged or archived (as they occur, the main keys for the principal table in the purge group; the detail of the lines purged or archived in the linked tables is never given, however in this case the number is indicated). If this box is not checked, for each table, there will be a message giving the total number of lines purged or archived for the table.

This box is also active in simulation mode, to identify the detail of what would have happened if the function had been launched in real mode.

Warning, the use of this box can lead to the creation of a very large log file.
