Liability in AP Invoice splitting while accounting invoice

Content (please ensure you mask any confidential information):

Users are created multiple lines at line level and liability account at invoice header level. They are accounting the invoice and system should sum and show single line of Liability in Credit line but its showing multiple lines based invoice lines.. In EBS it was sum up whole amount of liability and show one line.

Due to this issue, all AP reports are showing multiple lines in report level as journal created with multiple lines. Pls suggest the way to sum and create single line for sum amount for Liability account.
