Hi everybody,

I'm struggling with the following report situation:

I want to have all balances for two accrual plans shown as of 31st of Dezember 2018. However the balance is shown with calculation dates that have absolutely nothing to to with the task I'd like to achieve:

I am using subject area "Workforce Management - Accrual Real Time" in OTBI. 

My Columns are

WORKER [Firstname, Lastname, Person Number]

EMPLOYEE PLAN PARTICIPATION [Accrual type, Accrual Value (Measure)]

EMPLOYEE PLAN PARTICIPATION DETAILS [Balance Calculation Date]
