In the left combo box you choose the datacell
implementation
of the
column and in the text field the
actual column
value is entered. You can also choose a flow-variable to provide the value using the button on the right,
however the datacell implementation configuration is still necessary.
Note on Double values
Make sure that you use the '.' as the decimal
mark in a double value.
Note on Date formats
Note, the date parser uses localization settings so in order to
parse
foreign language date formats you will need to either convert
these
formats to the localized representation manually, or change
the
localization of your system to match that of your data source.
A
