Enhancement In ECC 6.0

Question

Hi Frnds,
I have implemented an enhancement spot in ECC 6.0. In enhancement Iam using internal table value and this internal table is populated in the main program ( Standard SAP Program). When I debugged the program, internal table is initial inside the Enhancement. I checked the internal table before entering into the enhancement it is having all values but as soon as it enters into the enhacement it is initial.
ENHANCEMENT 22  Z_ACCOUNT_ASIGHMENT.    "active version
SELECT SINGLE spart FROM mara INTO gv_spart
                      WHERE matnr = g_vtrlp-matnr.
ENDENHANCEMENT.
here g_vtrlp is internal table. It become's initial as soon as it enters into the enhancement. but outside it is showing values.
Can some one guide me to solve this problem.
I will give points for all who helps me.
Thanks in Advance.

Hi Chakravarthy,
According to the SELECT statement given by you you are retrieving a single field data i.e. SPART into a single field gv_spart based on a where condition gv_trip-material. My question to you is how can you refer to gv_trip-material in the where condition if gv_trip is an internal table. I suggest you try the below code and see if you are getting the desired result.
ENHANCEMENT 22 Z_ACCOUNT_ASIGHMENT. "active version
if gv_trip[] is not initial.
SELECT spart FROM mara INTO table gv_spart
for all entries in gv_trip
WHERE matnr = g_vtrlp-matnr.
endif.
ENDENHANCEMENT.
