"Request is too expensive to fulfill" error

[Sumio Ebisawa]

Hi 

https://developers.google.com/analytics/devguides/config/mgmt/v3/mgmtUnsampledReports

I received an error when I requested an unsampled report via the Google

Apps Script API. The error message is as below

> Request is too expensive to fulfill. To learn more about Unsampled

> Reports please see https://support.google.com/analytics/answer/2601061

The request conditions are as below;

range:  2015/03/01 - 2015/03/01, only for a day

metrics: ga:pageviews

dimensions: ga:pagePathLevel1,ga:pagePathLevel2,ga:pagePathLevel3

filters: none

It works when not specifying pagePathLevel dimensions. 

I read the linked pages but doesn't give me any hints. It seems working

properties with lower traffic.

Could anyone from Google explain me the detail of the error and how I

can avoid it.

Best regards
