+Edit Last Entered Work Notes
+
+This UI action is built specifically to edit the last entered work notes by the user in incident form or any table which support this journal fields.
+
+There is some restriction around journal fields/ work notes as user cannot edit or adjust the work notes that they entered. If they wish to edit it, I have introduced a new
+UI action which calls the UI pages which will automatically populates the last entered work notes/comments and user can adjust and submit it.
+
+Key actions: 
+sys_journal_field :
+ list.value = newcomment;  // update the new comment
+
+ sys_audit:
+ list1.newvalue = newcomment
+list1.oldvalue = '';     // clear the old value and update the new value
+
+sys_history_set:
+Delete the history record associate with the incident record
