What changed

  • Campaign data import requires a currency field whenever you upload cost data.
  • The currency can come from a column in the data source, or one fixed value can cover the whole dataset.
  • Google says this keeps campaign reporting accurate even if the property currency setting changes later.
  • Existing imports continue to report on the assumption that the imported cost matches the current property currency.

Who is affected

  • Anyone importing non-Google campaign cost data into GA4, especially across several markets and currencies.

What to check this week

  • Check that your campaign cost import file carries a currency column, or set one fixed currency for the dataset.
