(A) Same index
(B) Same view
(C) Same scope
(D) Same Custom report
Metrics and Dimensions should have the same scope level in Custom Reports. Metrics and Dimensions can have only one scope so you should use the same scope level for both metrics and dimensions otherwise there will be a mismatch in the reports. Example – A valid dimension-metric combination is User type and User. Both have the same scope User level. If you use a dimension-metric combination like Source and User then it will be invalid because the scope levels are different.
