The application will allow you to create Fiscal, Time-varying attributes that can be added to the Cost Plan Detail Object and placed on the List view in the TSV field.
There are 3 types of TSV attributes that can be created with 2 different calendar types ; however, it is recommended to only use 'Fiscal' calendar type of TSV and do not use the 'calendared' TSV for new attributes if you are going to use them with the stock TSV Fiscal attributes.
Use Fiscal calendar type and create a Money, Number or Percent data type attribute.
In the List View, add the attributes to the TSV and you can 'enter' data into the cells as shown in the example below
