MUNDOSAP - Problema con funcion Z

Hola a todos!

Tengo un problema, es primera vez que estoy haciendo una funcion. Ya la tengo lista o eso creo. Bueno, le pongo probar(F8) y todo bien, pongo el parametro que le estoy pasando y al momento de darle EJECUTAR (F8), me pone este error.

Err.tmpo.ejec. CALL_FUNCTION_NOT_ACTIVE
Excep. CX_SY_DYN_CALL_ILLEGAL_FUNC
Fecha y hora 29.10.2009 10:28:43

Texto breve
The function module is not active or contains no code.

¿Qué ha sucedido?
The function module "ZSGC_COTIZATOSOL" is called, but
cannot be found in its function group.

Error in the ABAP Application Program

The current ABAP program "ZSGC_COTIZATOSOL==============FT" had to be
terminated because it has
come across a statement that unfortunately cannot be executed.

An exception occurred that is explained in detail below.
The exception, which is assigned to class 'CX_SY_DYN_CALL_ILLEGAL_FUNC', was
not caught in
procedure "FUNCTION_CALL" "(FORM)", nor was it propagated by a RAISING clause.
Since the caller of the procedure could not have anticipated that the
exception would occur, the current program is terminated.
The reason for the exception is:
The program "ZSGC_COTIZATOSOL==============FT" contains the CALL FUNCTION
statement.
The name of the function module to be called is "ZSGC_COTIZATOSOL".
but "ZSGC_COTIZATOSOL" cannot be found in its function group.

Possible reasons:
a) The function module "ZSGC_COTIZATOSOL" has not been activated. Therefore,
it cannot be found at runtime.

b) The Function Library contains an incorrect entry for "ZSGC_COTIZATOSOL".

c) The function module contains no code, even FUNCTION ... ENDFUNCTION
is missing.

La cosa es que si esta activa y tiene codigo. No se ni a que moverle, si me pudieran ayudar se los agradeceria mucho!
