We have used ‘Fetch From’ successfully on several docTypes to update a field based on the data from a linked docType. However, in a Tree View docType, several Link fields that we need to update from a parent (using the parent_doctype) link cannot be set to use the Fetch From functionality. We are using Frappe/ErpNext V15 and when the Fetch From details are selected, the changes cannot be saved - and the response is ‘No Changes in Document’.
Does any one know a reason why there is this issue, or is it a bug?
Edit: I noticed this report - Fetch from not working if fetching 2 fields from same doctype in Form Builder · Issue #22695 · frappe/frappe · GitHub - would this be the same issue?
