Assign a value to missing matches between two tables

vibhoryadav23 — Thu, 17 Mar 2022 15:20:10 GMT

Hi,

I am pulling values from Table_2 in Table_1 with a realtionship. But there are some missing values in Table_2 which shows blank values in my Table_1. Instead of blank, I want to hard code a number eg - '8' or '0' whenever there is a missing match.

Table_1

User

Table_2

User	count
A	1
C	5
E	4

Expected output (Hardcoding '8' in this example)

User	Count
A	1
B	8
C	5
D	8
E	4
F	8

Thanks in advance.

You can substitute something else for blanks like this:

Count = VAR _Count = SUM ( Table_2[count] ) RETURN IF ( ISBLANK ( _Count ), 8, _Count )

Hi Alexis,

This work well with some minor changes. But it always shows all the vales even after I apply a filter. Is there a way to filter values with the respective filters.
For example - If I add a new column with user attributes, like age group and I filter on that, it still shows all the values.

It can be tricky since you have to specify which non-existing values you do and don't want to replace (how do you tell which blanks are which?). Can you give a specific example of what you're getting versus what you expect to get?

Ignore this for now as I have found a workaround for it (By creating a new table with unique values).

Thanks for your help!
