We need to create a DEAL in xstore which should be applicable to only the SALE line items not others

I am trying to create a deal which needs to be applicable to all SALE items, but for RETURN and ORDER or any other type it should not apply.

Trying to figure out what condition needs to be set in PRC_DEAL_FIELD_TEST of ITEM_FIELD column to check this. in DOC its says value1 is SALE but not sure what to add in ITEM_FIELD column.

If anyone has any one has tried this let me know. Thanks
