Find Duplicate Dates for One Client

[Taylorcc]

Hello, 

I have a table with ClientID and ContactDate

I am trying to find all of the ClientIDs that have more than one contact on the same date 

Is this possible? 

Thank you

if i understood correctly, one solution in the load script :

Data:
LOAD * INLINE [
    ClientID , contact, ContactDate
    1, c1, 01/01/2020
    1, c2, 01/01/2020
    3, c3, 01/01/2020
];

Group:
load ClientID,ContactDate,CountContact where CountContact>1;
load ClientID,ContactDate,count(contact) as CountContact resident Data group by ClientID,ContactDate;

drop table Data;

the output : the ClientIDs that have more than one contact on the same date

Thank you - that output is exactly what I am after 

I loaded the script and created a table but the CountContact field is only showing '-'
