As far as I know, this feature is no longer available in Infinity 23 versions. I believe the recommendation is always to create a case and change it to Withdrawn or Cancelled status if the case is no longer required.
@sumabhanul To avoid the temporary case creation but achieve the similar objective is to use the purge/archival of cases based on the required criteria/case status.
Pega stopped rolling out this feature. It is not recommended to use it anymore. Instead you can use Pega’s recommended Data Instance First design approach. You can get more info on it in the following link:
