If you have a block of demand days or expenditure values to record for the same row over several periods, clicking opens a new input row:
Here you can enter the number or value to Insert and choose how this is to be recorded. The input may represent a number of days, hours or FTEs (full time equivalent of a resource’s available time as a proportion of regular days) and it may be recorded against each period in a selected range or be distributed evenly across all periods in the range. Alternatively, it may be a revised daily cost rate that is to be substituted for each selected period.
You can alter the period range if required and click OK to record the entries in each period. Click again to hide the edit row. You can then adjust the row entries individually if necessary.
