about dimension buyer_network_name

[sorry chou]

Hi All,

We use Adsense management api to generate custom report for our customers, some pubid jobs run completed but some fail when dimension include buyer_network_name, the error message as follows

"errors": [ 

  { 

   "domain": "global", 

   "reason": "dimensionCombinationUnavailable", 

   "message": "The combination of requested dimensions is unavailable.", 

   "locationType": "parameter", 

   "location": "dimension" 

 } 

]

how to solve this problem?

thanks
