How to filter sales order on items with a COGS amount?

Question

I have a report for items that are shipped to customers without a charge, so that the COGS for these items can be moved into other expense accounts.  Items that were not booked to COGS do not need to be included.  The problem I am running into is that under criteria I cannot set "Fulfilling/Receiving Transaction: COGS Amount <> 0" because COGS Amount is not an option there (but it is under results?).  Under Criteria it is COGS Line which can only be true or false and either keeps everything listed or removes everything from results.

Criteria:

Type: Sales Order

Status: Billed

Main Line: False

Results:

Item

Quantity

Amount

Fulfilling/Receiving Transaction: COGS Amount

Item#1  Qty 1 Amount $0 COGS Amount $45

Item#2 Qty 1 Amount $0 COGS Amount $0

I only want item #1 to show in results.

I was able to resolve this.

Under Criteria I created a Numeric Formula:

CASE WHEN {fulfillingtransaction.cogsamount} > 0 THEN 1 ELSE 0 END

And is 1
