Answer 1

a. please provide the object_type of REWCUSTOMERAPI
b. maybe REWCUSTOMERAPI is a function?
e.g.
SQL> create or replace function fun return number
  2  is
  3  begin
  4  return 1;
  5  end;
  6  /
Function created.
SQL> exec fun
BEGIN fun; END;
ERROR at line 1:
ORA-06550: line 1, column 7:
PLS-00221: 'FUN' is not a procedure or is undefined
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
SQL> var res number
SQL> exec :res := fun;
PL/SQL procedure successfully completed.
SQL> print res
