I want the smartsheet to automatically update the “WIP (local)” column each month and reduce the current months forecast to £0. As you can see below, the “WIP (local)” column has increased and the forecast for September is £0 (this is fine). However, the smartsheet has now overestimated the total cost of the task (work done (wip local column) + forecast is = £338). When the cost of the task is actually £290.
The formula used to calculate work done is
=IF(TODAY() < [Start Date]131, 0, [Total Cost]131 / (MONTH([End Date]131) - MONTH([Start Date]131) + 1 + IF(YEAR([End Date]131) = 2021, 12, 0) + IF(YEAR([End Date]131) = 2022, 24, 0)) * (MONTH(TODAY()) - MONTH([Start Date]131) + 1 + IF(YEAR(TODAY()) = 2021, 12, 0) + IF(YEAR(TODAY()) = 2022, 24, 0)))
The formula used to calculate october forecast (£145 value) is
=IFERROR(IF(AND(MONTH(TODAY()) >= [Oct 20]$13, YEAR(TODAY()) = [Oct 20]$14), 0, (IF(OR(YEAR($[End Date]131) > [Oct 20]$14, AND(MONTH($[End Date]131) >= [Oct 20]$13, YEAR($[End Date]131) >= [Oct 20]$14)), IF(OR(YEAR($[Start Date]131) < [Oct 20]$14, AND(MONTH($[Start Date]131) <= [Oct 20]$13, YEAR($[Start Date]131) <= [Oct 20]$14)), $[Total Cost]131 / (MONTH($[End Date]131) - IF(AND(MONTH(TODAY()) > MONTH($[Start Date]131), YEAR(TODAY()) = YEAR($[Start Date]131)), MONTH(TODAY()), MONTH($[Start Date]131)) + 1 + IF(YEAR($[End Date]131) - YEAR($[Start Date]131) = 1, 12, 0) + IF(YEAR($[End Date]131) - YEAR($[Start Date]131) = 2, 24, 0)), 0))) * $Rates$202) * (1 - $[% Complete]131), 0)
Appreciate any help.
