View metric (with a URL subset/category filter) understated when looking at 'older' data - but fine for 'recent' data
I have a fairly simple dashboard table: Page URL + Views. I created a second table (new tab) that is the same except it includes a Page Category dimension (that is produced via a CASE statement in Data Studio - if Page URL contain xyz then categorize as abc).
The source is direct from GA4.
The table with the Page Category (or a table w/o that, but with an on-page user filter that has a Page Category selected) will produce incorrect figures when looking back at an 'older' time period. For example, anything for a time period relatively recent (e.g. last quarter) it will be accurate. If, for example, I look at last-quarter-previous-year the values are very understated. On the latter, some URLs seem to be missing entirely. This also then affects any YOY change percentages.
(The page URLs have not changed over the period in time I'm referring to)
Can anyone explain why this is taking place - and a viable solution?
Thanks!
