I want to add a comma on an integer field, but don't see a setting on the field itself. According to the help documentation, this should be possible.
You should check the 'enable grouping' cehckbox on an integer field. After having done this, you should make sure that the localization settings are set either at the tenant (or) user level. While setting the localization settings you get to choose the number format which should be used to format the number fields (integer, decimal). The formats are comprehensive enough and you should be able to find the one you need.
Is that the only feature that the Enable Grouping checkbox does? Not very intuitive for the end user. Thanks for the quick response though, it works as I would expect now.
Yes, that is the only feature that enable grouping does. The earlier dropdown (pre 3.2) was named 'Grouping separator' & we maintained a similar convention even for the new checkbox (in 3.2) .
