YTD issue in ASO Cube

Hi All,

I have a requirement to copy actuals to forecast for one of the data type which i was able to achieve , but unfortunately YTD is not working as first 2 months is sitting different data type of Forecast and another 10 months in another data type of forecast.

I created a parent data type and added two above 2 data types as shared members , so that all the forecast sits in single place , but when i checked on YTD for parent data type, still in accurate.

All these are being done in ASO cube
