Integration profile -proportion different from the Worksheet UI entry

Hi,

We are seeing that the  Integration Profile is having different behavior  (when handling proportions) versus when we enter the data directly at the in the Worksheets.

Is this the expected behavior ? I assumed that the Integration profile will be identical behavior as the worksheet w.r.t to the proportion.

Business case-

User will enter data for a series at Item-(NOT the lowest)-Week (Lowest)-Customer (Lowest).

Item will have multiple vendors - For the UI, when we enter at the Item level, system will proportion it among the vendors based upon another custom series.

However when we upload the data from the Integration profile, we are seeing that the system will equally proportion it among the multiple vendors.
