I'm running into a very odd issue with consistent filtering on a date column thats being generated from a formula:
We have a column labeled "Filter date" that is set to Date (Restrict to dates only not checked)
which has the following formula to trim off the date from a 2ndary column that is a drop down:
=IF([Date Scheduled]1 = "Complete Parts To Inspection", "", IF([Date Scheduled]1 = "Complete Tool back to Tool Room", "", IF([Date Scheduled]1 = "Parking Lot", "", IF([Date Scheduled]1 = "TBD May", "", IF([Date Scheduled]1 = "TBD January", "", IF([Date Scheduled]1 = "TBD February", "", IF([Date Scheduled]1 = "TBD March", "", IF([Date Scheduled]1 = "TBD April", "", IF([Date Scheduled]1 = "TBD June", "", IF([Date Scheduled]1 = "TBD July", "", IF([Date Scheduled]1 = "TBD August", "", IF([Date Scheduled]1 = "TBD September", "", IF([Date Scheduled]1 = "TBD October", "", IF([Date Scheduled]1 = "TBD November", "", IF([Date Scheduled]1 = "TBD December", "", IF([Date Scheduled]1 = "", "", RIGHT([Date Scheduled]1 + "", LEN([Date Scheduled]1) - 3)))))))))))))))))
This formula looks at the date in date scheduled and does several If statements to yield the desired date only from that column.
The issue we are running into is that we cannot filter on the "filter date" column consistently with either manual filters or saved filters. Here you can see with the "2 Day View" filter selected it seems to give us no results.
Now to make things even more interesting, if i select the "Filter date" column and change its properties from date to text/number, and then change them back to date. the filters suddenly work
Then once you save the sheet, reset the filter and go back to the 2 day view, you once again get zero results.
Any help on this would be greatly appreciated and if anyone has a similar issue please let me know what you have done to work around it.
