Hello Toby,

After merging the files, certain columns are missing. These columns also cannot be selected manually, as they are missing from the selection options as well.
For example, I have a column "TgmName" that is missing in the merged files and also cannot be selected.
I would expect the structure of the columns in the merged files to be the same as in the individual files.

Single file:


Merged files:



Best regards,
Stefan

Thanks for letting me know Stefan. 

I think you might have unknowningly had a parser configuration which was causing a conflict.  With automatic parser configuration, this is easilly done by clicking 'OK' to accept the suggested configuration.  Sometimes suggested configurations can differ significantly based on the data found in the file.

Thanks again,

Toby
