Regardless of the import data format, you must always specify all key dimensions (iskeydimension="TRUE" attribute of the refdim element in the definition of the data series, see technical reference PPM Customizing) and at least one of the process instance-independent measures of the data series. You can optionally specify further process instance-independent measures or non-key dimensions of the relevant PIKI cube in the import data structure.
