[Koha] integrating KOHA with other financial system

Hello Team, Im pretty new here, I have query where I have been tasked with getting fines from the koha system and exporting this to the existing ERP the insitute is using, I have managed to create a sort of a bridge to export from koha to the other database, from the database level, I am using the table "accountsline" table and successfully took my records to the finance ERP... the payments are done there and I need to update my koha I am inserting back to the same table successfully but when I go to the patrons' fines list in koha the entry "my payment" is there but the total havent cleared what do I need to do here. thanks -- Dennis K.
