Adding a field to a data table

[Willie]

I need to add a new field to an existing data table that already contains data.  When I try to add the new field in the data shape, a dependency confirmation popup window appears. 

Does this mean that the fidelity of the existing data cannot be guaranteed if I add a new field?  What kind of negative impacts could occur by adding a new field?

If the field has a default value, then the default value will be used when you search for entries using the FindDataTableEntries

Otherwise I’ve never experienced any negative effect by adding a field.
