Set the system property ` sn_ap_apm.exception.engine.max_parallel_thread_count ` which defines the number of parallel threads used by the exception engine scheduler to process invoice exceptions.

## Before you begin

Role required: admin

## Procedure

1. Navigate to All.
2. Search for All properties under System properties.
3. Search for ` sn_ap_apm.exception.engine.max_parallel_thread_count ` and open the system property.  
   The system property `sn_ap_apm.exception.engine.max_parallel_thread_count` opens as a record. The Value field displays the default value as 4. This value indicates 4 worker threads of your instance will be used by the exception engine scheduler when it executes. You can edit the record in editing mode.
4. In the Value field, you can enter the value as 6, or 8.  
   The exception engine scheduler makes use of 6 or 8 worker threads in your instance when it executes. This is recommended only when you have more than 2 nodes, i.e more than 16 worker threads.
5. Select Update.
