During July 2025, Dusija focused on backend development and database management for ERP systems, specifically addressing financial data integrity in the frappe/erpnext and aerele/erpnext repositories. Dusija enhanced account currency validation by updating queries to consider only active, non-cancelled general ledger entries, using Python to implement an is_cancelled = 0 filter. This approach corrected previous discrepancies where cancelled entries could affect currency validation, ensuring more accurate financial reporting and consistency across ERPNext forks. By applying parallel fixes in both repositories, Dusija improved auditability and reduced the risk of currency mismatches, demonstrating a methodical approach to backend data correctness.
