Dear Fran, thank you very much for your answer. Indeed, there were some identical field names. I changed this and the geoprocess is calculating something. But the result is very strange: 3 layers are created: one point, one line and one polygon-layer. I thought that there should be only one polygon layer. I have the impression that the resulting polygon layer only contains the features of one source layer. Any ideas?
