Arm your field agents to edit the custom fields related to a particular ticket while providing service in the field. This helps the field agent to add precise details for the ticket that they are working on.
For instance, the field agent for water purifier servicing needs to update the parts to be replaced in the ticket information. As the existing information gathered by the customer service agent on call mentions replacement of Part A only but while on the visit, the field agent found fault in part B as well. For precise tracking on customer query, custom fields storing information for parts to be replaced need an update in this particular case.
