Fractions and Laboratories

[mkline]

I am just wondering what other people's experiences have been using 'fractions' for distinguishing between data for different laboratories, and/or lab vs field measurements, or do you store some of this metadata in a different way? Have you found it useful for comparing/ excluding data from different sources?

I am also wondering if anyone else has been getting the same error when trying to set up the column configuration for importing a sampling from csv in a way that includes columns that reference a given fraction such as 'fraction laboratory', I keep receiving an error that reads "Fraction info set in columns but never applied to a result value", and I cannot figure out how to resolve this without removing these columns altogether. I tried adding the other columns that consist the required fields under the fraction tab such as date of entry and fraction number, however this did not seem to help.
