Hi @anji87543,
You could use a process variable for task’s Assignee property and set it up like that: ${UserName}.
Now, it depends how you’re back-end looks like, but there are many options to set a value to a process variable. Sometimes it is simple to get it from the task’s form, having an input mapped to the variable,
or set it via client script.

Let me know if that helps.

@anji87543 If you want to change the assignee in backend, then you have to add a task listener to the usertask and then you can set like the below:

public class TaskUpdateListener implements TaskListener {
  
  @Override
  public void notify(DelegateTask delegateTask) {
	delegateTask.setAssignee((String) delegateTask.getVariable("assigneeVariable"));
  }
}

In this example, i was setting the assignee value for the task from the processvariable “assigneeVariable”

@anji87543 you can check in the table ACT_HI_IDENTITYLINK table and query for taskid and update it
