Rolling data profile not copying data to all combinations

Hi,

I have a rolling data profile defined to copy source series data to target series. Forecast only.

Source Series: Sales Forecast

Target Forecast: Published Forecast

When I execute profile data is getting copied to different item id, location id combination which is under same t_ep_id though.

e.g. both item id's are for same t_ep_item with different demand class.

sales_date     Sales Forecast     Published Forecast     Item ID     Location ID

3/1/2016          1300                    0                              17055          4521   

3/1/2016          0                         1300                          30030          4521     --After execution of rolling profile

Let me know if anyone has any idea why this happening.

Thanks,

Santosh
