What-if scenarios

FrePPLe allows users to easily create alternative plans. With the scenario management you can easily create copies of the complete model.

During the installation a number of what-if slots are configured by the adminstrator. See this page for the details.

The scenario’s can have the following states:

  • Free: The slot is currently unallocated and available for use.

  • In Use: Data has been copied into the scenario slot. Users can freely work independently in the scenario, without affecting the main model.

    When scenarios are in use, a drop down list appears in the upper right corner. It allows you to select the scenario to work in.

    Scenario selection

In the execution screen, you can change the status of a slot:

  • Copy is used to duplicate an existing schema into a free slot.
    After copying the scenario slot moves from free to in use.
  • Release is used to flag that work on the what-if scenario slot has finished.
    After releasing the scenario slot moves from in use to free again.
