Read the input records into a transformer stage.

Now give 2 output columns:

Cash_receipt_id: Populate the input Cash_receipt_id
Amount: If Status = Cleared Then Amount Else (-1) * Amount

Now add the Amount field group by Cash_receipt_id in aggregator stage and you will get the desired output.

Note: Remember to sort on Cash_receipt_id in aggregator stage.
