View Object Totals by Month for Validation Purposes (or Fallout)!
Step 1:
Create a new report by clicking on New in the Home menu.

Step 2:
Add a table to your report by clicking on Table in the Report menu.

Step 3:
Drag a column over to the Rows section - any column - you're going to remove it later.

Step 4:
Right-click within the report's white space and select Convert to Legacy Table.

Step 5:
Right-click again and select Edit Data Path towards the bottom.

Step 6:
Replace everything that appears in the Edit Data Path with the following and click OK.
<%=CurrentBuildPath()%>/
CostModels/
Default/
Cost/
.DateGoesHere/
.Unassigned/
!GROUPBY[{Object},{Category }]/
!NEWCOLUMN[{Network Devices}=Object]/
!NEWCOLUMN[{Object Name}="Object"]/
!NEWCOLUMN[{Name}=Object]/
Step 7:
It's going to show 'No data to display' at first. Go to the Data menu and click on the Choose icon.

Step 8:
Select the following columns:
Step 9:
Now add Formula Columns to show the data by month (I usually add enough for the full year).


Keep adding these so that you have Period-1 through Period-11. If you want to view at the beginning of the fiscal year and look forward instead of backward, then you would use +1 through +11 instead.
This way you have a full fiscal year view like the one below and you can take a screenshot or export before configuration changes, and then review afterwards to see what changed. To make it easier, you can add a Formula Column for Total that adds all the period columns together.

You can also make a copy of this report and modify it to review fallout by month as well. For your calculated columns, instead of using {Cost}, you would use {Unassigned } (notice the space after the 'd' - not a typo, you're gonna need that).
That's all folks! 😊
