Need help with Distinctcount

Hello,

I am using distinctcount to summarize data and it gives me an error and says it exceeded the resources. Let me give details.

Below is my measure 

Clients=summarize(

clients,[client_number],[customer_number],[Year], 

"Clientcount", distinctcount(clients[id])

)

thats my measure table and I am using another measure to get the count where it is greater than 1.

otheclientmeasure=If(values(clients[Clientcount]>1,"yes","")

when I add above measure on the matrix for some clients it gives me exceeded resource. Can you please help me how can I fix this issue?

Thank you.
