Configuration - Gap Filling | NextGen FSM

Configure Gap Filling in NextGen FSM to generate a virtual schedule that fills capacity around already-assigned activities, for review and confirmation onto the Daily Plan.

Configure logs

Before using a Gap-Filling model, set the log level for the process: configure the parameter company.fsm.gapfilling.logtype on Technical Settings > Company.

Company and system parameters

Company parameters define the global behaviour of Gap Filling Scheduling. Configuration path: Technical Settings > Company.

Parameter	Type	Purpose
`company.fsm.forwardscheduling`	Boolean	Flag to enable the Forward Scheduling module (Gap Filling + Direct Future Scheduling).
`company.fsm.gapfilling.logtype`	Long	Sets the Gap Filling processing log level: `0` = Disabled (default), `1` = Memory, `2` = DB.
`company.fsm.gapfilling.enableMultiStage`	Boolean	Enables multistage process handling in gap filling.

Set permissions

Navigate to FSM > Configuration > Core > User > User Types.
Select the user type that must access Direct Future Scheduling.
Open the Permissions configuration.
Enable the required permissions:
- Gap Filling : View — allows users to view the Gap Filling tab in the Daily Plan.
- Gap Filling : Edit — allows users to use simulate scheduling options and to configure models.
Save the user type configuration.

Configure a Gap-Filling model

Navigate to Configuration > Scheduling Optimization > Scheduling Models.
Click New Gap-Filling Model.

The model is organized into: General Parameters, Advanced Parameters, Reprocessing Parameters, plus the Team, Crew Shell and Activity selection tabs.

General Parameters tab

Field	Editable	Description
ID	No	System-generated identifier. Created automatically; cannot be edited.
Operation Center	No	Automatically populated from context.
Selection Mode	Yes	Include or exclude selected resources. For more information see the dedicated page.
Description	Yes	Short business description of the model.
Extended Description	Yes	Optional extended description.
Active	Yes	Enables or disables the model.
To Crystallize	Yes	Whether the model's result is intended to be applied to the Daily Plan.
Automatic Validation	Yes	Whether the result is auto-validated or needs manual confirmation.

Advanced Parameters tab

Parameter	Description
Detailed Total	Enables detailed count logging, for troubleshooting/analysis.
Minimum days range	Maximum number of days included in a single Gisware call.

Reprocessing Parameters tab

Parameter	Description
Simulation Rule	Simulation rule used during processing.
Exchange activities among resources	Whether an already-assigned real-plan activity stays pinned to its resource ("Never remove") or can be removed ("No"). Can be overridden per Work Order Type/Cycle/Activity Type on the Activity tab.
On Duty Availability	Whether on-call resources are scheduled based on the Simulation Rule's filters.
Saturation Resources (%)	Percentage of resource saturation considered during processing.

Team, Formation, Crew Shell and Activity tabs

Team / Crew Shell: scope which resources and crew shells the model considers.
Activity: override the model-level "Exchange activities among resources" value for specific Work Order Types, cycles or activity types. An activity not matching any override uses the model's global value.

Configure the scheduling process for an Operation Center

Navigate to Configuration > Scheduling Optimizations > Operations Center.
Locate the desired Operation Center.
Click its Settings button, then New configuration.
From the Type dropdown, select Gap-Filling.
Enter the OSS Params and any optional information.
Click Insert.

Associate the daemon to the Gap-Filling algorithm

Navigate to Configuration > Scheduling Optimizations > Associate OC/Daemons.
Select the Operation Center, click Search, then New.
In Algorithm, select Gap-Filling.
Enter any additional optional values.
Click Save.
