Hi,
I have a requirement to allow the user with specific permission to import data from CSV file.
On import, system will check for contacts if they don't exist than create new one. Also update another custom entity for all the records in CSV.
Can anyone suggesting me the right approach to do this.
I am thinking of publishing a small web app which will perform all operations by making web service calls to CRM. A button will be displayed on ribbon for the user to access the web app and import their csv.
Thanks
