I have a database of roughly 9000 rows. My first sheet is this data in a raw format (Masterdata!). Each row is a fire-rescue response call and therfore has a time stamp. The raw data uses different formats to provide the time stamp. My second sheet is my filtered data (Filtereddata!). In order to make these time stamps uniform I have a formula that looks at the Masterdata! timestamp column and if it is in a numeric format changes it to a text date and if it is a text date perserves it.
=IF(ISNUMBER(Masterdata!K:K),TEXT(Masterdata!K:K,"dd/mm/yyyy hh:mm"),Masterdata!K:K)
This gives me the "timestamp" which has both the incident start time and the date. I have =left and =right formulas breaking apart the date and the time. Therefore I have two columns on my Filtereddata! for the date of the incident and the time the call came in. What I would like to do is run some pivot tables and group incidents by month. I am unable to group them once I run the pivot table. I get a "Unable to group these items" (or something like this) message. I have assured multiple times that the date column is in DATE format. However, when I change the date to long date or short date I see no changes in the column so I am assuming there is something happening that I'm missing. The formula populating the date column on Filtereddata! is as such:
=LEFT(frfiltereddata[[#This Row],[Timecode]], FIND(" ", frfiltereddata[[#This Row],[Timecode]], 1))
Any ideas or suggestions are appreciated.
Thanks in adavance.
