What can I do if I cannot open a CUF (or SUF) with my Stata version because it contains too many variables?
Usually it is possible to load only a part of a data set with certain commands.
In principle, the search portal only lists the data products available in the RDC-DZHW. If you do not find what you are looking for, you may find further DZHW inventory data or data from other research data centres in Germany helpful.
