The input layers have csv files as external attribute tables (attached to the layer via Layer properties > Joins). Columns taken from the csv files are getting displayed as <csv file name>_<actual column name>. For this reason, the column names of the layers don’t match and the resulting layer has a separate column for every input file. I tried to get rid of <csv file name> using Layer properties > Fields but I get an error („Could not rename field.“). </p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Any idea how to solve this?</p><p class=MsoNormal>Thanks a lot!</p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
