DAX statement does not see the table

Anonymous — Fri, 28 Feb 2020 10:54:55 GMT

Hi Guys !
I have got a simple problem, but for some reason under DAX it is not so simple.

I have got two tables:
i); all_ip_addresses, ii); chosen_ip_addresses

ii); Chosen ip addresses contain two columns, the addresses and description for each.

In both cases I operate with String.

I was going to create a simple column with IF statement that will check if chosen ip's are contained within some of those in all_ip_addresses. If they are, print the description from ii); chosen_ip_addresses, else print ip address from all_ip_addresses.
When I am trying to do that, DAX does not seem to see my chosen_ip_addresses table at all.
The relationship between tables seem to be created correctly as when applying data to a simple table in visualization it seems to work.

Unfotunatelly the data is sensitive and I can not pass it over. I hope that I clearly explained it.

So the column would end up like :

Wanted_Output

Hi Anonymous

Use RELATED or RELATEDTABLE functions when referring to another table.

If what Mariusz says doesn't work you might try LOOKUPVALUE.

InfoColumn= IF(CONTAINS(RELATEDTABLE(chosen_ip_addresses),chosen_ip_addresses[Ip], all_ip_addresses[Ip]), chosen_ip_address[description], all_ip_addresses[Ip])

I have tried that just before texting here, maybe I am just aproaching it incorrectly.
Just at the end when I am trying to get the description, the DAX does not see that table/column, and I can not get that value.
Does my example at the top makes some sence ?

I was kind of based from this :

Column =
IF (
    CONTAINS ( RELATEDTABLE ( Table2 ), Table2[Country of Origin], "CHILE" ),
    "CHILE",
    "OTHER COUNTRIES"
)

Thank you for you time and help.

Kind Regards,
Bart

Hi Anonymous

Try columns like below, this will check if there was any transaction in chosen_ip_addresses table related ( using active relationship ) to the table the column is in.

Column = CALCULATE( COUNTROWS( chosen_ip_addresses ) > 0 )

Hey Mariusz !

That seems to be working, I am getting a list of chosen_ip_addresses when its true.
Might be a "stupid" question but, how would i get the description from chosen_ip_addresses to be visible in place of TRUE and the ip address from all_ip_addresses in place of FALSE ?
I really appreciate your help,

Kind Regards,
Bart

Hi Anonymous

Can you send a screenshot of the relationship between these two tables?

Ok Mariusz !

I think I have figured it out.

InfoColumn = if(CALCULATE(COUNTROWS(chosen_ip_addresses) > 0), RELATED(chosen_ip_addresses[Description]) , all_ip_addresses[Ip])

This has solved my problem !
Thank you for your time !!
