Abstract
Differences between metallicity measurements of dwarfs and giants belonging to the same open clusters, as envisaged, would have tremendous implications, among the other things, on the planet formation theory and on the stellar populations in the Milky Way. They also have a high importance on their own right, as they would point to possible problems in atmosphere modelling of evolved stars. However, they have not yet been evaluated based on solid and conclusive data. We analyse and review literature and available archive data, using different models and line lists, in order to investigate the extent, the origin, and the nature of the aforementioned differences.
