Path: Organization > Lookups > Biomed Make/Model / PMs Tab
In order to make accurate calculations on the item records, the Base PM field requires a date entered on the Biomed Make/Model / Identity Tab.
When you enter the Next PM Date on the Biomed Make/Model / PMs Tab, WebTMA calculates the difference (in days) between the Base PM and the Next PM Date.
When you create a biomed record associated with a Make/Model and you enter a Base PM Date on the biomed record, WebTMA adds the difference calculation (in days) to the Base PM Date and populates the Next PM Date column on the Biomed > Records / PMs Tab with the 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 Biomed record:
Base PM Date = June 3, 2015
WebTMA calculates the Next PM Date as July 18, 2015
