En jouant avec mon code, j'ai compris ce qui n'allait pas.
J'avais besoin d'ajouter la ligne suivante dans mon bloc de code d'exception :
v_line := NULL; v_sr_no := v_sr_no + 1;
Code final :
DECLARE

v_data_array wwv_flow_global.vc_arr2;
v_rows number;
v_sr_no number := 1;

v_error_cd number :=0;
v_quote_pos1 NUMBER;
v_quote_pos2 NUMBER;
