Hi Umakant, yes I imported historical data. In fact, I had to do it many times before the numbers of orders for certain time ranges were even close to accurate. There are 1421 orders YTD on this specific customer site.
Here’s how it went with importing historical data:
First time – imported only about half the orders (YTD) – about 700 orders
Second time – imported more orders, but only up to about 1000
Third time – getting closer, now at ~1300
Fouth time – probably about as close as it’s going to get – within 40 orders of actual (1381)
I have actually compared the report to the list of actual orders and there doesn’t seem to be any pattern over missing orders in the new WooCommerce Admin reports. In some cases, it’s missing a single order in the sequence here and there, and in other instances, several orders in a sequence are missing. The missing orders are pretty much the same as other orders (completed status).
For the record, I have also tried this plugin on several other customer sites with less order volume, and those didn’t have the same issue. One other site has 796 orders YTD, and the WooCommerce Admin reports for orders shows exactly the same. The revenue totals match perfectly too.
Very strange, inconsistent behavior with this plugin, from one site to another it seems.
