How can we apply the same LOB mapping set rules to Invoice Distribution and Payment accounting?

Summary:

We have account rules for Invoice Distribution that use an LOB mapping set. Our mapping set uses the Department to determine LOB. However, the rules are not being carried over to the payment accounting and it is causing discrepancies in our GL accounting. How can we apply the same LOB mapping set rules to the Payment accounting? Thank you.

Example:

For Department 1010 we have an account rule, which points to a mapping set, that indicates for this department the LOB should be 10000. We can see the rule is being correctly applied to the invoice distribution.

However, in the Payment accounting the Journal Entry for Department 1010 is defaulting to LOB 000000 which is incorrect.
