A member of our support team gave me a list of 100 Account ID's and their associated 'Customer Success Manager' in text form. I was asked to upload this data to salesforce, using Data Loader.
I asked if I could have the ID of each customer success manager, but was informed that it was not available from the account object.
When I tried to upload the data, I received this message on each of the accounts:
Customer Success Manager: id value of incorrect type: 'name'
It would appear I need to provide an ID for each of the customer success managers, but how to get that, Im not sure.
