SAP - Problemas con SO_DOCUMENT_SEND_API1.

Buen día, tengo un inconveniente con la función SO_DOCUMENT_SEND_API1.
Yo quiero enviar un archivo Excel (.csv ) Adjunto. La función me genera el archivo,
Pero no realiza los saltos de renglón, es decir me coloca todo en un solo renglón largo.

Vi en algunos ejemplos de la red que para solucionarlo Concatenaro un tipo de dato X, con el carácter de salto de renglón, al final del string. Pero cuando lo intente me tiro un error, ya que solo puede concatenar datos de tipo char.
Se les ocurre alguna solución ¿?

Ejemplo de solución:

CONSTANTS: con_cret TYPE x VALUE '0D'.

CONCATENATE:
text-002 text-003 text-004 text-005 text-006 text-007 text-008 text-009
INTO gv_file_lines SEPARATED BY gc_delim.

CONCATENATE con_cret gv_file_lines INTO it_attach.
APPEND it_attach.

Mi codigo.
