Hi,I have created a simple workflow using Workflow Modeler that contains the following steps:-1. Submit the modified files to review.2. Review the files.3. Approval/reject4.DeployMy problem is I am unable to add the reviewer user, in Reviewer Task. It only shows the default values like "$AREAOWNER" and "$USER" but i want to give a specific username who should review the changed file and accept/reject it.Also, on saving the model, it gives an error that the external task (Review task) does not have an owner.Please help in solving this problem.Thanks.
