I have a task where I need to do a mass status update of tasks in C4C. I did the following:
Via Data workbench I have downloadad all the tasks that need to be updated in a csv file. Now, as far as I understand I need to use the xlsx template to reupload the tasks with the new status. My question is, which ID do I need to use as the "External Key" since in the downloaded csv file, the External Key field is empty? I tried using the Task number, and the object id as external keys, but every time new tasks were created and the tasks that were already there weren't updated.
Thank you for your help, and sorry if this is a simple question!
