Scheduled programs

can a programm be wriitten to extract /generate data and scheduled to work only for a specified time period and revert back to original way.after the time period lapses?

for eg… valuation of inventory … on First in first out basis… be changed mid way… and programmed to value last in first out … for 3 months only and start valuaing on first in first out basis after 3 months ???



I don’t think so.
