The combinations (both AdGroupName + ImpressionSharePercent and AdGroupStatus + ImpressionSharePercent) does not return any report url.
The initial request for the report had
<h:ReportRequest xsi:type="h:ProductPartitionPerformanceReportRequest"><h:ExcludeColumnHeaders>false</h:ExcludeColumnHeaders><h:ExcludeReportFooter>true</h:ExcludeReportFooter><h:ExcludeReportHeader>true</h:ExcludeReportHeader><h:Format>Csv</h:Format><h:Aggregation>Daily</h:Aggregation><h:ReturnOnlyCompleteData>false</h:ReturnOnlyCompleteData><h:Columns><h:ProductPartitionPerformanceReportColumn>ImpressionSharePercent</h:ProductPartitionPerformanceReportColumn><h:ProductPartitionPerformanceReportColumn>Clicks</h:ProductPartitionPerformanceReportColumn><h:ProductPartitionPerformanceReportColumn>Impressions</h:ProductPartitionPerformanceReportColumn><h:ProductPartitionPerformanceReportColumn>Spend</h:ProductPartitionPerformanceReportColumn><h:ProductPartitionPerformanceReportColumn>AdGroupCriterionId</h:ProductPartitionPerformanceReportColumn><h:ProductPartitionPerformanceReportColumn>CampaignName</h:ProductPartitionPerformanceReportColumn><h:ProductPartitionPerformanceReportColumn>PartitionType</h:ProductPartitionPerformanceReportColumn><h:ProductPartitionPerformanceReportColumn>ProductGroup</h:ProductPartitionPerformanceReportColumn><h:ProductPartitionPerformanceReportColumn>TimePeriod</h:ProductPartitionPerformanceReportColumn></h:Columns><h:Filter/><h:Scope><h:AccountIds><a:long>1223569</a:long></h:AccountIds></h:Scope><h:Time><h:CustomDateRangeEnd><h:Day>27</h:Day><h:Month>5</h:Month><h:Year>2020</h:Year></h:CustomDateRangeEnd><h:CustomDateRangeStart><h:Day>11</h:Day><h:Month>4</h:Month><h:Year>2020</h:Year></h:CustomDateRangeStart></h:Time></h:ReportRequest>
Which resulted in
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"><s:Header><h:TrackingId xmlns:h="https://bingads.microsoft.com/Reporting/v13">51504a60-1a6c-4f6f-9419-c02406a94b64</h:TrackingId></s:Header><s:Body><SubmitGenerateReportResponse xmlns="https://bingads.microsoft.com/Reporting/v13"><ReportRequestId>1581374020914</ReportRequestId></SubmitGenerateReportResponse></s:Body></s:Envelope>
Then making request for that report
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"><s:Header><h:TrackingId xmlns:h="https://bingads.microsoft.com/Reporting/v13">cbd63059-c818-4ad2-b9cd-eee2bf802b17</h:TrackingId></s:Header><s:Body><PollGenerateReportResponse xmlns="https://bingads.microsoft.com/Reporting/v13"><ReportRequestStatus xmlns:i="http://www.w3.org/2001/XMLSchema-instance"><ReportDownloadUrl i:nil="true"/><Status>Success</Status></ReportRequestStatus></PollGenerateReportResponse></s:Body></s:Envelope>
Here there is no report url.
@Eric Urban - MSFT these have the tracking id and report id.
