Example:
place_123, 01/06/2016, 6
place_456, 24/05/2016, 4, NOT WORKED
The weeks are created working backwards from the date given in the file. So for the example data above WORKED weeks will be created for place_123 from 01/06/2016 back to 27/04/2016, and NOT_WORKED weeks for place456 from 24/05/2016 back to 03/05/2016.
The placement must already exist. Any existing worked weeks created from timesheets will not be affected but manually entered work history will be overridden.
