Enhancing a TYPES definition in a TYPE-POOLS

Question

I'm trying to add a new field to the following type:
shipment cost document item
TYPES: BEGIN OF V54A2_VFKP.
         INCLUDE STRUCTURE VFKP.
TYPES:   ACR_AMT_LOCC LIKE VFKP-NETWR,
         ACR_AMT_FORC LIKE VFKP-NETWR,
         INV_AMT_LOCC LIKE VFKP-NETWR,
         INV_AMT_FORC LIKE VFKP-NETWR,
         OPN_AMT_LOCC LIKE VFKP-NETWR,
         OPN_AMT_FORC LIKE VFKP-NETWR,
         COLOR(3),
         CHECKBOX,
"""""""*"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""$"$SE:(1 ) Typ V54A2_VFKP, Final                                                                                S
$$-Start: (1 )----
$$
ENHANCEMENT 1  Y_AGENTE_DE_SERVICIO.    "inactive version
       Descripción de agente de servicio.
include structure YSDS001,
ENDENHANCEMENT.
$$-End:   (1 )----
$$
       END OF V54A2_VFKP.
The point is that I can't activate the enhancement because I get a syntax error. Is it possible to enhace the TYPES declaration. What is missed?
Thanks in advance.

Hi Susana,
Try the following to rectify the error. I have given my comment against the statement INCLUDE STRUCTURE YSDS001.
* shipment cost document item
TYPES: BEGIN OF V54A2_VFKP.
INCLUDE STRUCTURE VFKP.
TYPES: ACR_AMT_LOCC LIKE VFKP-NETWR,
ACR_AMT_FORC LIKE VFKP-NETWR,
INV_AMT_LOCC LIKE VFKP-NETWR,
INV_AMT_FORC LIKE VFKP-NETWR,
OPN_AMT_LOCC LIKE VFKP-NETWR,
OPN_AMT_FORC LIKE VFKP-NETWR,
COLOR(3),
CHECKBOX,
"""""""*"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""$"$SE:(1 ) Typ V54A2_VFKP, Final S
*$*$-Start: (1 )--------------------------------------------------------------------------------$*$*
ENHANCEMENT 1 Y_AGENTE_DE_SERVICIO.
Descripción de agente de servicio.
include structure YSDS001, "Here instead of a COMMA(,) replace it with DOT (.)
ENDENHANCEMENT.
*$*$-End: (1 )--------------------------------------------------------------------------------$*$*
END OF V54A2_VFKP.
This worked for me and should work for you as well. If it doesn't work then please let me know the exact error so that I can resolve the issue.
Reward accordingly.
