Allocation Manager needs to loop multiple segments

Summary:

We have a complex allocation that needs to occur. However, I am skeptical of the robustness of the allocation tool.

We will have a bucket of burdened labor costs sitting in one natural account. This is because the PPM module cannot have one expenditure type to many cost bases and thus many burden rates. The PPM module will assign a department and project code (both parts of the account string) dynamically via SLA. It will change from employee to employee.

We are trying to then allocate these costs dynamically out to multiple different natural accounts based on a fixed percentage. However, the issues we are having with the allocation is that our department and project segment will vary. The project value set has almost 300 records. The allocation is not liking using a level 0 hierarchy to try and capture all values in the hierarchy. How would the looping functionality be able to solve this issue? Can the allocation look dynamically through the department and project segments?
