Incompatibility data in pivot table
I'm doing a data studio with a Pivot Table with a google ads by supermetrics source.
I'm putting "brand" on row dimension; "month and year" in column dimension; and cost in Metric, and data studio says "Incompatible fields"
I tried differents combinations, and if I take "brand" off, and i replace by "campaing name", that's correct and I can see all datas in the Pivot Table.
There is any incompability between brand and cost ?
