ABAP SALV CHECKBOX AND EVENT HANDLER

Boa tarde pessaol da comunidade, eu estou a escrever essa para explicar como fazer um report usando SALV onde uma das colunas é CHECKBOX usando técnicas de OOABAP e usando cursos para exportar valor para tabela interna.

• primeiro passo definir os tipos e as tabelas que iremos usar ao longo do programa, iremos criar um TYPES DE CLIENTE COM 3 CAMPOS que terão checkbox em colunas “IGNR” , “ACTUALIZAR” “PRINCIPAL”, tornando que se activem unicamente em cada linha.
