I try to import products with dataflow, (import->dataflow) but I see no "category_ids" Where is it? in earlier versions in the drop down list was "category_ids", in 1.9.1 I see it not.
So I go to System->import/Export->Dataflow-Profiles, then I create new Profile -> Import/Export Profile, there in "Data Format" I set "Original Magento attribute names in first row:" to NO
then i "Field Mapping" -> I careate Fiel Mapping and in Drop Down for list I see no record for category.
By export Dataflo->All Products, I see after export in .csv-File the column "category_ids", but for import I cannot choose it, it missing
