September 2025: Delivered targeted enhancements to the Employee Advances filtering in frappe/hrms, enabling more precise data retrieval and reconciliation. Implemented UI-level and form-level filters: added link-field filters in Link.vue and a new account_type: 'Receivable' filter in the Employee Advances form (Form.vue). Also standardized the filter data structure and currency representation to improve consistency across reports and exports. The work reduces manual filtering time and improves data accuracy for finance and HR operations.
