In your headcount planning process, you can edit jobs within your scenario using the following methods:
Edit jobs from the Changes tab - You can make changes within the context of your previously-made scenario changes.
Edit jobs from the Data Sheet tab - You can make new changes to your scenario (which are then reflected in the Changes tab). You can also edit multiple jobs from the Data Sheet tab. When editing jobs from the Data Sheet tab, you can use ChartHop filters to further streamline the process.
