Hello,
We've recently been experiencing issues with the Campaign Criterion Service in v201409 returning CampaignCriterion of CriteriaType 'PRODUCT_SCOPE' with criterion that have null dimensions.
These null criterion.dimensions appear to correspond to the new Inventory Filter options 'Channel' and 'Channel exclusivity' that are available through Shopping settings (advanced) in the AdWords UI. Campaigns that have only these Inventory Filters selected return criterion objects with no dimensions. These changes in the AdWords UI appear to be very recent.
I'm unsure of whether this is intentional or not but at this time we have no way of properly identifying these ProductScope dimensions as referring to 'Channel' or 'Channel exclusivity' or what their values might be.
Any help on this issue would be greatly appreciated.
Thanks,
Michael
