Add a Column Based on a Formula Calculation
If you choose Formula as the data entry method, you can create a numeric, a "date add," or a "date difference" type of formula to automatically calculate the values for the fields in the column.
The numeric formula option is only available if the data source you specify has been built on the SYS Numeric Logical Datasource data definition.
A "data add" formula takes the value from a date field and adds the value of another field to it. This option is only available if the data source you specify has been built on the SYS Date Logical Datasource data definition.
A "date difference" formula takes the value from a date or date field and subtracts it from the value in another date or date field. This option is only available if the data source you specify has been built on the SYS Numeric Logical Datasource data definition.
