Hi Abhilash,
Sorry I'm a little confused and probably doing something wrong or a missing a step. Here they are:
1. Create a new SQL expression field "Total_Items" with the following formula:
(
Select Count (T."field") from Table T
)
2. Use the formula:
Count ({Items})/{% SQL Expression}
However, I cannot use the formula in the first step since I do not have a field in the table that I can count. "Age" is a custom field that is calculated by using the following formula: Age = (currentdate - 1) - {Table.Service_Date}
Without the Age > 30 record selection filter, I get back 793 records, and with this filter turned on I get 12 records back. Hence the compliance rate formula should be 12/793 = 1.51%
Can you please let me know what I maybe missing?
