I have a table that I am trying to filter using a date slicer. The problem is that the table is set up with a month/year column for each month, and a row for each of over 300 sites, and an event count for each location during any given month. (example below)
I have a separate "Date" table that I am using as a Dim table, but I cannot create a relationship with 16 month columns.
I have thought of transposing the data into 3 columns, Site, Date, Quantity, then I can have a 1 to many relationship with the date. The data transposition will mean writing a macro i guess which is possible, but hoping for a better way. The database is updated monthly by adding a new column for the new month.
Any suggestions would be appreciated.
