  • NOTA: Para poder activar los Field Exits debemos tener el parámetro abap/fieldexit = YES seteado en el servidor (Transacción RZ10).
  • Crear field exit:
  1. ejecutar reporte RSMODPRF
  2. Crear módulo de función con nombre FIELD_EXIT_*
  • Ejemplo, validar campo KBSTAT en trn. VK11, VK12 & VK13
