Time estimates can be converted to story point and this way enabling individual resource management within a team.
To set the conversion rate go to Box configuration LINK.
Task planned using the Board can align with your Time-boxes and the story points can be evenly distributed over the duration of the task.
Such view enables the monitoring of the individual team members and is especially useful during the agile transition in the organisation.
If the Task has no Story Points the warning is returned.
When the "Show overall assignment" (Enterprise feature) is enabled the capacities may be misleading. This is due to the planning process using the Board module and the fact that Story points should not be converted to time units.
