Hi Micah,
The
error means that you are not allowed to view the API column (TOTAL_LINE_ITEM_LEVEL_IMPRESSIONS) as this feature is not yet enabled in your network. I think that only the inventory-level dynamic allocation is enabled in your network, not the line item-level dynamic allocation. That said, could you try to use the
TOTAL_INVENTORY_LEVEL_IMPRESSIONS column in your report?
Also, so I can verify this, could you provide to me your report parameters (dimensions, columns, date ranges, etc) and your network code? You may use the Reply privately to author option when replying.
Thanks,
