Collect with Sum - An Error has occured on the server
I got a collect with sum problem.
Source module (Before creating the line item for Collect):
Dimensions: Time, Department
Line item: Cost1, Cost2 (Number format)
Dimensions: Time, Department, Charter of Accounts
Line item: Cost (Number format)
In order to get the costs from the source module I've created a LISS of Cost1 and Cost2 and created an additional line item called Collect that picks them up in the source module. This collect line item has same dimensions plus the LISS.
I have a Mapping Module dimensioned by this Charter of Accounts, to which I have added a line item and formatted it with this LISS, and selected where I want the LISS items (Cost1 and Cost2) to map to in the Charter of Accounts.
I am now trying the below formula in the Target module for the Cost line item:
Source Module.Collect()[SUM:Mapping Module.LISS]
I get below error message:
