oracle - Tracking failed transaction in bulk insert/update/delete -

i have following code structure

procedure ..      pragma exception_init(dml_errors, -24381);     l_errors            number;  begin   -- busines logic   forall table_1 delete;   forall table_1 update;   forall table_1 insert;   forall table_2 insert;   forall table_2 update;   forall table_2 insert; exception   when dml_errors     --extract error indexes end; 

each of forall loop deals separate table of array i.e., loop deleting table_1 deal table of table_1_u index pls_integer;

each forall loop has save exceptions keyword

now, how can extract "for" failed , "which record in index failed".

how can extract "for" failed

with call stack (format_error_backtrace) or implementing sort of steps:

procedure ..      pragma exception_init(dml_errors, -24381);     l_errors            number;     istep number; begin   -- busines logic   istep := 0;   forall table_1 delete;   istep := 1;   forall table_1 update;   istep := 2;   forall table_1 insert;   istep := 3;   forall table_2 insert;   istep := 4;   forall table_2 update;   istep := 5;   forall table_2 insert; exception   when dml_errors       if istep = 0       elsif...       end; end; 

which record in index failed

by using bulk_exceptions cursor:

procedure ..      pragma exception_init(dml_errors, -24381);     l_errors            number;     istep number; begin   -- busines logic   istep := 0;   forall table_1 delete;   istep := 1;   forall table_1 update;   istep := 2;   forall table_1 insert;   istep := 3;   forall table_2 insert;   istep := 4;   forall table_2 update;   istep := 5;   forall table_2 insert; exception   when dml_errors        in 1..sql%bulk_exceptions.count loop          dbms_output.put_line('error #' || || ' occurred during '||              'iteration #' || sql%bulk_exceptions(i).error_index);               dbms_output.put_line('error message ' ||              sqlerrm(-sql%bulk_exceptions(i).error_code));       end loop;        if istep = 0       elsif...       end; end;
