Power BI - SUM IFF Across two (not related) tables - powerbi

Question

I need help about Power bi.
PROBLEM:
I have two tables (most of the fields in the tables are the same, but tables are not equal) , I have Unit name in both tables, and I need a table (output) that contains each Unit and the COUNT of the unit (how many time that unit is in table 1 and in table 2) based on 2 conditions:
I have to count only units that have status not equal to "rejected".
I have to count only units that have the Department_Name = "TX"
I used this DAX measure (but it didn't work):
Measure = calculate(
COUNT(Table 1[Unit_Name]) + COUNT(Table 2[Unit_Name]),
Table 1[Status] <> "rejected",
Table 2[Status] <> "rejected",
Table 1[Department_Name] <> "TX",
Table 2[Department_Name] <> "TX")
The purpose is to use the measure in a PowerBI chart and insert on the X axis the measure, on the Y axis the unit_name (I don't know if I have to use unit_name by Table 1 or unit_name by table 2).
I also tried to create a connection between tables using unit_name as primary key.

Answer 1

there are many ways to do that but the quickest and easiest way is to merge the two tables in to one like
go into the power Query editor , and merge the two tables into one using Power Query Script
for details on how to merge the two tbale data set in power Query see the below link :

after doing this your table will be one instead of 2 tables and you can easily perform the count on single column "Department Name" for the Unit occurance.

Answer 2

Using DAX, It is a 2 step process:
First Create a new table with this DAX Code:
FullJoin = UNION(Table1,Table2)
Your Table will look like this:
Then Create a measure with DAX Code like this:
Solution = CALCULATE(
COUNTX(FullJoin,[Unit_Name]),
FullJoin[Status] <> "rejected",
FullJoin[Department_Name] = "TX"
)
Now If we test it on a visual,
