In this IMG activity, define the relevant volume allocation server group(s).
The standard PRA volume allocation process will create background jobs across all available background processes within an SAP system using standard batch process load balancing.
However, if a large amount of allocation jobs are submitted at the same time, all available background process queues on available servers will be filled, and other same-priority jobs will not be able to execute in a timely manner. This may present a problem in some situations for specific customers. For that reason, SAP has made this option available in customizing. You can choose to "dedicate" servers in server groups to be used only for volume allocation.
When you set this up here, the volume allocation process will target specific servers during job submission. The concept of server groups is used to do that. A server group can be created to only include a set number of defined servers. During the volume allocation job submission, all background jobs will be submitted to each of the defined servers in the server group in a 'round robin' manner. This will allow various application servers to NOT be included in the server group, thus leaving them available for other processes within the SAP system.
Note: The SAP concept of server groups is used in a load balancing context. RFC server groups are used in asynchronous remote function calls, which utilize dialog processes. However, volume allocation executes purely in the background, utilizing batch processes. NONE of the load balancing configuration attached to the Volume Allocation server group which the customer can create is considered because of this.

Activities
Within this IMG activity:
1. On the CCMS: RFC Server Group Maintenance screen, the Log-on group is the server group, the Instance is the specific server, and the Status represents the status of the assignment (the status traffic light icon should be green). Choose Create Assignment (or from the menu, choose Edit --> Create Assignment).
The Create Assignment dialog box is displayed.
2. In the Group allocation screen area of that dialog box, in the Server group field, enter the relevant server group. In the Instance field, enter the instance (the server that you would like to include in the server group).
In the screen area below, in the Determination of resources screen area, make entries in the following fields:
- Activated (0 or 1) - 0 means that resource determination is deactivated. 1 means that it is activated. The default is '1'.
- Max. requests in queue - number of maximum requests in the dialog queue.
- Max. no. of logons - number of log-ons in the system.
- Max. no of WPs used (work processes) - the total number of dialog work processes that can be used.
- Min. no. of free WPs - number of dialog work processes that should remain free for other users.
- Max. no. comm.entries - the number of communication entries in the system.
- Max. wait time - the quota for wait time.
3. When you have made your entries, select Copy.
