How can I calculate the sum of a column, then use that sum to perform another calculation?

I need to perform a number of calculations. The first part is to find the sum of a particular column and then divide the sum by it's single value in the row.

LiabilityBal / Sum of LiabilityBal.


I've created a data grid with some test data, and used a group by step to perform the aggregation. This performs the calculation I need.


The non-populated fields need to be calculated, with WeightedAmtCalc being calculated with the above formula.grid data.PNG





I've tried splitting the streams and using a lookup on the id, but that only matches one row.



This is the result I get, Ideally I would like to have the sum on each row. The sum field on row 1 is the sum of all of the fields in the second column.



Is there a way for me to put the sum back into data stream where the sum appears on each row, so that I can then perform the calculation?


Thanks for your time
