Availability Transfer Between SAP HR and SAP Multiresource Scheduling 
If you use SAP HR for personnel resources, you can transfer availability information from SAP HR to SAP Multiresource Scheduling and vice versa. The following standard infotypes can be transferred in principle in both directions:
Absences (infotype 2001)
Attendances (infotype 2002)
Alternative working times (infotype 2003)
Planned working time (infotype 0007) can only be transferred from SAP HR to SAP Multiresource Scheduling.
You have configured the following settings in Customizing for SAP Multiresource Scheduling:
To transfer the availability information of the resources from SAP HR to SAP Multiresource Scheduling Basis, you use report /MRSS/HCM_RPTWFMIF. For more information, refer to the system documentation for the report.
Note
If you start the /MRSS/HCM_RPTWFMIF report to transfer availabilities from SAP HR for a resource currently displayed in the planning board, you cannot create, change, delete, or save any objects (assignments or time allocations) for this resource. After the report has run, the objects can be saved. To be able to further process the objects of the resource, you have to refresh the planning board first.
Time allocations with time allocation types indicated as exceptions in Customizing for the WFM Core under Define Time Allocation Types are displayed by the system in the planning board as bars. As a resource planner, you cannot change these transferred time allocations. Time allocations with time allocation types that are not indicated as exceptions in Customizing are displayed by the system in the bar chart as gray or white background to the rows.
If you have defined alternative working times or planned working times using a daily work schedule, the system transfers the planned working time as availability to SAP Multiresource Scheduling for fixed working times, and transfers the normal working time for flextime. For resources with flextime, the system differentiates availability, nonavailability, as well as the potential availability and displays the times between the planned working time frame and normal working time in a different shade of gray in the planning board.
Example
For a resource with flextime, the planned working time frame is set from 08:00 to 18:00, the normal working time from 08:00 to 17:00. In the planning board, the time of potential availability from 17:00 to 18:00 is displayed in a different color to the times of availability and nonavailability.
In the Configure Settings for HR Integration IMG activity, you control which availability information is also created in SAP Multiresource Scheduling and transferred to SAP HR. Alternative working times and time allocations for which a group is entered in the table and the Resource Planner Relevant indicator is set are available to the resource planner in the planning board.
In SAP Multiresource Scheduling, you cannot edit or delete time allocations transferred from SAP Multiresource Scheduling to SAP HR after they have been saved. You can delete alternative working times but not edit them once they have been transferred to SAP HR.
If you create HR-relevant time allocations in the planning board, you cannot enter any descriptions.
If an HR-relevant time allocation is currently being created in the planning board, the system blocks the relevant personnel number in the HR system.
You can only move HR-relevant time allocations in the planning board in such a way that they do not cross daily limits.
