How to count values that appear in two tables
I can't provide actual data but I have two queries/tables I'm trying to compare. Table 1 has a bunch of IDs and services provided to those IDs. These IDs can and do show up multiple times (multiple rows) in Table 1 since services occured on different dates over time. Table 2 contains a list of IDs that are considered "current" and each ID appears only once in this table. I want to calculate a rate of how many current IDs have had services, i.e. the number of current ID's from Table 2 that are present in Table 1 / the total number of current IDs in Table 2. I've tried to create a calculation that filters Table 1 to only the IDs that are also present in Table 2, determine the distinct count of those IDs, and then divide that by the total count of IDs in Table 2 but can't get it to work. Not sure if I should be using a calculated column in one the tables or creating a measure. The ID colums in both tables are setup to have a one to many relationship. Thanks so much!Solved5.3KViews0likes1Comment
