RE: server_error_server_error while fetching unfilled_impressions with line_item_type

[Ad Manager API Forum Advisor]

Hi,

Thank you for contacting the Ad Manager API support team.

​Please be informed that I have removed your response from the forums as it contains the PII information.

I would like to confirm that the "UNFILLED_IMPRESSIONS" metric is not compatible with LINE_ITEM_TYPE and ORDER_NAME dimensions.

Please note that all the combinations of dimensions and metrics are not compatible. In order to check the compatibility and build a report, you must build your reports in the UI first and retrieve it via API. So, you can easily find out which dimensions and metrics work together and which do not. 

Thanks,
 

Ad Manager API Team
