Keywords Performance report multiple rows per keyword

[StewartR]

Hi,

The docs for the `KEYWORDS_PERFORMANCE_REPORT` suggest that there is one row per keyword but I find that I am getting multiple rows back for each keyword when just selecting `Cost` and `Id`.

How do I find out which attributes are segmenting the data?

[StewartR]

My mistake, the missing segment is (of course!!) adGroupId because keywordIds are not unique in themselves.... Apologies!

Hi Stewart, 

Glad to hear that you figured out the solution. AdGroupCriterionId is unique only in the scope of the AdGroup. You can refer to this guide for more details on the scope of object uniqueness in AdWords.
