DAX -calculated column to sum values grouped by another column

[PhoenixBird66]

I want to create a new column called CalculatedBatchTurnover which sums up the values from another column (CalculatedBatchLineTurnover), grouped by another column (Batch Header No).

See the example in my picture below.

Tried to do this a few ways but cant seem to get it right.

Any help greatly appreciated.

CalculatedBatchTurnover = CALCULATE(SUM(Table[CalculatedBatchLineTurnover]),FILTER(Table,[Batch Header No]=EARLIER(Table[Batch Header No])))
