To manage postponements in SKED, the status of fixtures can be set to Postponed from within SKED Draws & Results. The fixtures will display as postponed on the draws & results widget of a published draw.
Bulk Edit can be used to set multiple fixtures to a postponed status. See this article
Games that are set to a Postponed status will automatically become unallocated to a venue.
When a rescheduled date has been confirmed to play the postponed games, the fixture status then needs to be reset to Confirmed. Each fixture requires editing to the new date and venue using the edit icon next to it in the draw modal of Comp Builder. See this article
