Relationships between tables null values

[Anonymous]

Good day, 

I have searched tgrough forms and not sure if I found the answer or understood the logic. I have issue with relations ships beween tables. 

I have 3 tables: 

1) NAME OF SHOPS - 104 lines 

2) AUDIT OF SHOPS - arround - 96 lines as not all shops audited

3) DETAILS OF SHOPS - arround 90 lines as not all shops have details 

When I crete relationships between colums "NAME" of shops - there will be 90 lines, due to 14 shops are not mentioned. I want to see and indentify which 14 were not mentioned, therefore I I need to understanh how relations ships will not filter first source column from the table "NAME OF SHOPS"

Thnaks

filter('name of shops',isempty(relatedtable('audit of shops')))

Thanks. "AUDOT of SHOPS" is a multy colunm table. The relation ships needs to be between NAME OF Shops column. I think RELATEDTABLE doesnt allow myltycolumn expression. 

Is there workarround for this? Cannot figure out myself. 

I;m thinking to experiment on Merging tables and replace "NULL" values with some other word (but that is my last option).

I have gone to MERGING tables option. Would like still to see if there are other otiion to use relationsships when source column is not filtered in case there is no vaule in related column....
