We faced an issue recently when it came to posting invoices ( after allocating the charges) for purchase orders having more than 5000 lines, the batch job would execute for close 1 day and then fail. We did this 3- 4 times and still had no results.

The workaround solution was to split the purchase order invoicing , by selecting 100-500 records and then removing the other records and repeating them until invoices are posted.

Please optimize or make it faster to post-purchase order invoices having huge number of lines,
