Controlling the Batch Size of Processes
You can control the batch size of various Revenue Management processes using the Revenue Management Batch Settings custom setting. You must be signed in with administrator permissions to manage these custom settings.
If you are getting batch job errors, you might want to try adjusting the batch size used by the process.
To adjust the batch size used by a particular process, add or change the batch size using the Revenue Management Batch Settings custom setting. The default batch size will be used for a process until you change it.
See Managing Custom Settings for more information.
To monitor the progress of an Apex job, from Setup click Monitoring | Apex Jobs. The queue lists any Batch Apex jobs that have not finished execution. The Total Batches column lists the total number of batches for the job. The Batches Processed column lists the number of batches that have been processed. See the Salesforce Help for more information.
