E-Ledger application is a program developed with SAP integration in order to be used effectively. With this integration, users can create ledgers through the application and then directly transmit the necessary commands to the SAP system to forward these ledgers to GIB. After the relevant transactions are completed in the SAP system, the ledgers created in the E-Ledger application and sent to the GIB can be viewed easily. This integrated structure makes transaction processes more efficient, while providing traceability and reporting.
