How to get the expression correct ?

[suvechha_b]

Hi All ,

Please kindly assist me to get my requirement correct. How to show the no of policy cancelled on UW_MONTH_KEY.

In Database , we have a Policy_cancellation_date. Say for eg , For UW_MONTH_KEY= 201909 which is fiscal_period . The policy count will occur if the policy_cancellation_date is also UW_MONTH_KEY i.e 201909.

Sample model attached.

Thanks in advance.
