What is the Journal Entry Rule Set for the Balance account for cleared cross currency payments?

We have a cross-currency payments cleared in CM, when create accounting the system generates a Balance line, we know that account comes from the Ledger Options, but as we have to many Legal entitles and Bu's assigned to the ledger, we would like to change one of the GL account segments using SLA.

The issue is that I cannot found the Journal Entry Rule Set that generates this journal line in the Journal Entry Rule Set for payables.
