DAX - circular dependency

[Worstkees]

Hi,

I keep running into: A circular dependency was detected: Consumer[Companyname], Consumer[Companynameknown], Consumer[Companyname].

Here is a simplified view of the tables used (with the Companynameknown as desired column).

Companytable:

companyID	CompanyName
1	Aaa
2	Bbb
3
4	Ccc
5
6
7	ddd

Consumer table

Companyid	Companyname	Consumerid	Companynameknown
24	Abc	544	Yes
44		545	No
69	Bcd	546	Yes
178	Dff	547	Yes
244	Etc	548	Yes

Where in the Consumer table:

Companyname = LOOKUPVALUE(Companytable[CompanyName],Company[companyID],[companyid])

I tried to get the Companynameknown based upon the content of the Consumer[companyname] column ->

Companynameknown= if(Consumer[Companyname]<>blank(),"yes","no").

Based upon articles in the forum I tried to achieve this with e.g. measures, with allselected, etc. etc. but keep running into the same error message. For me it is not an option to remove the relationship between the tables.

All suggestions are welcome!

Thanks in advance

Hi @Worstkees ,

Since you have established a relationship between Consumer table and Companytable, please try using the RELATED function.

Companyname = 
RELATED ( Companytable[CompanyName] )

Companynameknown = 
IF ( [Companyname] = BLANK (), "yes", "no" )

If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.

@Worstkees , if Companyname is in Consumer table as column

this should work as a new column

Companynameknown= if(isblank(Consumer[Companyname]),"yes","no")

Thanks @amitchandak ,
Unfortunately this still gives me the same error:

All suggestions are welcome!
