I am trying to download a SHOPPING_PERFORMANCE_REPORT with the following fields:
- OfferId
- ProductTitle
- Brand
- Date
- Impressions
For a small subset of records I'm getting empty/blank data for OfferId, ProductTitle, and Brand (only Date and Impressions are not null). I want to exclude NULL OfferId and the filter: WHERE OfferID != ''
doesn't seem to make any difference. How do I exclude NULL values from my report query??
