After enabling Data Guarantee, receipts will be sent to your sharing (source) instance in batches of 1,000 by default. However, you can modify the batch number that receipts are sent to your instance in by modifying the receipt_batch_ack_size and receipt_batch_error_size values in the Perspectium Properties table.
Prerequisites
First, you will need to install DataSync for ServiceNow and run the Perspectium Finish Install scripts.
Procedure
To modify the batch sizes for receipts that are sent to your sharing (source) ServiceNow instance, follow these steps:
Log into your sharing ServiceNow instance and type u_psp_properties.list in the Filter Navigator on the left-hand side of the screen.
In the Search section at the top of the list view, choose Name from the dropdown. Then, type *receipt in the search window and hit Enter.
In the resulting list of properties, locate the com.perspectium.receipt_batch_ack_size property. Double-click the value in the Value field and then modify the value to the desired batch size you would like to create for batched acknowledgment receipts and click the 
icon to save your changes. Then, locate the com.perspectium.receipt_batch_error_size property. Double-click the value in the Value field and then modify the value to the desired batch size you would like to create for batched error receipts and click the icon to save your changes.
