Get error when calling function that returns a table

I have got a procedure (test.sql) and this calls a function (test_rr.sql) which returns a table. I use the SQL:

Call test();

I get the error:

ERROR: invalid input syntax for type integer: "(14891,0,"VIMALBA ","P901 ",111.000000)"

CONTEXT: PL/pgSQL function test() line 13 at FETCH

SQL state: 22P02

Can anyone help please
