Path: Organization > Lookups > Equipment Make/Model / PMs Tab
In order to make accurate calculations on the item records, the Base PM field requires a date entered on the Equipment Make/Model / Identity Tab.
When you enter a value in the Next PM Date field on the Equipment Make/Model / PMs Tab, WebTMA calculates the difference (in days) between the Base PM and the Next PM Date.
When you create an equipment record associated with a Make/Model and you enter a value in the Base PM Date field on the equipment record, WebTMA adds the difference calculation (in days) to the Base PM Date and populates the Next PM Date column on the Equipment > Records / PMs Tab with the newly calculated date.
Example of PM Date Calculation
Make/Model Base PM Date = January 1, 2015
Make/Model Next PM Date = February 15, 2015
Difference calculation = 45 days
On the Equipment record:
Base PM Date = June 3, 2015
WebTMA adds 45 and calculates the Next PM Date as July 18, 2015
