Background: A month ago, we updated our MAINT calendar to not skip weekends and holidays.
If a monthly PM Action is supposed to be due on the first of a month, but if it was generated prior to the MAINT calendar change, its Maintenance Plan will show some due dates that are on the 2nd or 3rd of a month (if the 1st was a weekend of a holiday).
In such a case, I used the “Regenerate Plan” option and the future due dates are all corrected to the first of a month, as expected.
What is UNexpected, however, is that PAST maintenance plan entries (with Due Dates that are NOT on the first of a month) are added to the maintenance plan after the REgenerating.
For example, the Maintenance Plan tab (prior to REgenerating) had a line with Due Date =1/1/2022 (Saturday), which is good. After I used the “Regenerate Plan” RMB option, in addition to that line, IFS now shows another line under the Maintenance Plan tab with Due Date = 1/3/2022 (Monday), this line unnecessary.
Why does it do it? Can I make “Regenerate Plan” function leave the PAST Maintenance Plan entries alone?
thank you so much!
