Hello.
OK My accounts fields have say for example 20 imported fields.
So if I want to import additional data into an Accounts Record for all 75000 records. If I import the ID Line (the 32digit ID field that it’s already known by in Suite) and the new fields of data I want, to add but leave everything else so i’m only putting in the ID and two fields, it won’t delete all the existing information for the users, it will just import the two extra fields for each account, and not wipe out the other existing data.
