Person Responsible in the Team 
You can specify one employee as the responsible person in each team. This is useful if you use SAP Multiresource Scheduling with mobile devices and want just one employee in each team to receive information using the mobile device. You can set this indicator in the integration settings for the mobile device to ensure that only the person responsible receives information about the current service requirements on his or her mobile device.
Note
Mobile device integration is not included in the functions of SAP Multiresource Scheduling.
You have activated the Team Responsible indicator in the Define Planning Board Profile IMG activity.
You specify a responsible person when you define the team in the resource planning board. A column is available next to the member list in the team details for you to do this.
If you create a team without a responsible person, the system automatically selects the first resource listed in the team as the responsible person.
