Some GKONT values are * on display RSA3

Hi gurus,

I have enhanced 0FI_GL_14 with ZRAKNO which takes GKONT values same. I didnt use the standard field due to its differently use.

When I check the enhancement result I see some values take * values on rsa3 though fbl3n shows lets say the account number(120300553).

I used FM in cmod for enhancement as below.

.....

gv_gkont like bseg-hkont,

.....

CALL FUNCTION 'GET_GKONT'

             EXPORTING

               BELNR           = l_s_faglposbw-belnr

               BUKRS           = l_s_faglposbw-bukrs

               BUZEI           = l_s_faglposbw-buzei

               GJAHR           = l_s_faglposbw-FISCPER(4)

               GKNKZ           = '1'

             IMPORTING

               GKONT           = gv_gkont

               "        KOART                 =

               "        GHKON                 =

             EXCEPTIONS

               BELNR_NOT_FOUND = 1

               BUZEI_NOT_FOUND = 2

               GKNKZ_NOT_FOUND = 3

               OTHERS          = 4.

           l_s_faglposbw-zrakno = gv_gkont.

Why these values are missing?

How can I gain those values?

Any help would be appreciative.
