Forecast release to ECC multiplied by buckets in the DataView

Dear Gurus,

my DP PlanningArea is in months and I created a DataView and Time bucket of future 3 months. I check the quantities at the technical period level and they seem to be ok. However, when I release the forecast to ECC I see that the monthly quantities are multiplied by 3 which is my time bucket .

For Eg: In my Planning Book, Forecast figures per month is 15000 for 3 months and Time bucket is also future 3 months.But when forecast is released to ECC, it is showing as 45000 for all 3 months in MD61 in ECC demand Management.

Please help to resolve the issue.

Regards

Amit
