Custom measure is not disaggregated

I currently have a measure that has the following hierarchy:

Dimension	Hierarchy	Stored Level
Customer	Customer	Customer Site
Demand Class	Demand Class	Demand Class
Organization	Enterprise	Organization
Product	Product	Item
Sales Organization	Global and Marketing Organization Hierarchy	Sales Rep
Time	Gregorian Calendar	Day

Aggregation Parameters:

• Calculation Order —> Calculate then aggregate
• Time Simension —> Sum
• Other Dimensions —> Sum

Disaggregation Parameters:

• Disaggregation Type —> By measure
• Disaggregation Basis —> Final Shipments Forecast
• Secondary Basis —> Shipments History Average

I've uploaded a line for this measure via FBDI, but at the Legal Entity level. The goal of this is so I can see this line broken down by business unit and organization in the demand plan.
