I am trying to do a split to exclude records where the additional value in the delivery (looking at the current table) IS NOT EQUAL TO a current value selected in the workflow. Is there a way this can be done?
I can only currently look at the current table (deliveries).
You cannot query a temporary table, this is because there won't be any valid Filtering Dimension for that Query Activity. Without a query you won't be able to select the desired value and then match it with the Delivery's additional value.
