Thank you for clarifying. Here's how to capture an initiator's department name:

1. Add a hidden field requester_department_name
2. Configure Post Processing Tool:
   Tool: Update Form Data
   Field: requester_department_name
   Value: #currentUser.department.id#
   Run on: "Data Creation" only – This will ensure that the department name is only stored once when the form is submitted by the initiator. 

Hope this helps. 

How can I store the department name of the request initiator in a form ? The form passes through multiple users, I only want to store and preserve the department of the initiator for the entire process.

The answer provided earlier,is not what I am looking for.
