I am working in CRM. I would like to create a measure that counts rows in the leads table that contain a particular contact ID from the contacts table. The leads and contacts tables do not have a relationship. When I try to set one up Power BI complains that this would create ambiguity with another table that both are already related to.
I have created a calculated column in the contacts table:
The solution that BILASolution has posted works for individual contacts but I can't get it to work for a group of contacts. For example, if I want to see the average number of leads sent to contacts who purchased in a specific date rang. When I try to include this measure in an average I get an error saying "Column 'Contact Lead Count Measure' cannot be found or may not be used in this expression". Just in case I have created the measure incorrectly I've included the code below. If I don't use average it just gives me the count for the first contact in the group.
Is there a way to get a measure that can be used to count matching instances of a value in another, unrelated table, that can also be used again in sum and average measures? In this instance that's counting leads related to contacts in Dynamics CRM?
I would look at adjusting your table relationships so that you can create the necessary relationship. Generally this means adjusting the direction of your relationships. Can you post a picture of your relationships?
