Hi TT,
It would be good to understand what is the reason behind needing to load data to the same entity via two separate profiles.
I'm guessing this might be that each profile might be loading data for the same Entity but against different Profit Centres for example?
If that's the case, you might want to consider using workflow Channels.
Note: sometimes, specially in Planning cubes, this raises the question if Profit Centre should not be on the Entity Dimension itself (having business entities as UD1 for example). There's a chapter on the Design an Application course that explains the considerations around this topic in detail.
