This document defines classes and methods to display transactional data from table BKPF in an ALV grid. It declares a data type TY_BKPF to represent table rows, and populates a table T_BKPF with query results. A class GCL_EVENT handles double-clicks by launching transaction FB03. Method CREAR_ALVGRID builds the ALV grid, populating it from T_BKPF and defining field catalog and layout. Selection screen parameters filter the query results loaded into T_BKPF.
