The performance of Auto Invoice is affected by several factors. Checking the following could improve performance considerably.

When using the interface_line_attribute fields, create indexes on RA_INTERFACE_LINES_ALL for these fields. Use the minimum number of interface_line_attribute fields.

Some installations use RA_INTERFACE_DISTRIBUTIONS_ALL to populate accounting details while populating segments instead of code combination IDs. In this instance, create an index for segments to improve performance.

If possible, populate all the code IDs for the RA_CUSTOMER_TRX_TYPES_ALL, MTL_SYSTEMS_ITEMS, and RA_TERRITORIES tables in RA_INTERFACE_LINES_ALL instead of passing values.

When loading more than 5,000 invoices, split them into batches of 5,000. A batch of more than 5,000 rapidly decreases Auto Invoice performance.

For a batch with 3,000 to 5,000 invoices, run more than one instance of AutoI nvoice by giving a value between five and eight in the Number of Instances field in the Auto Invoice Run screen. This will split your data into five to eight batches (and five to eight import programs), increasing performance.

The amount of memory allocated to Auto Invoice for validation can affect performance. \Navigate System System Options Invoice and Customers and enter three MB in the Max Memory (In Bytes) field.
