Issue with Read_Text FM

Hi All,

I am using the FM Read_Text for reading text from S010 but its behaving strangely. With the same data if i execute the FM in SE37 transaction, i am getting proper results but while executing in ABAP , its not returning any data as well as no exception. Below is the code written, please suggest if i am lacking something.

   DATA BEGIN OF TEXTHEADER.
        INCLUDE STRUCTURE THEAD.
DATA END OF TEXTHEADER.

DATA BEGIN OF LINES OCCURS 10.
        INCLUDE STRUCTURE TLINE.
DATA END OF LINES.

   DATA: name like THEAD-TDNAME,
      object LIKE THEAD-TDOBJECT,
      ID like THEAD-TDID.

CLEAR TEXTHEADER.

   ID = '0001'.
name = GS_HD_REF-ORDER_NUMB.
object = 'VBBK'.

   CALL FUNCTION 'READ_TEXT'
  EXPORTING
   CLIENT                        = SY-MANDT
    id                            = ID
    language                      = sy-langu
    name                          = name
    object                        = object
*   ARCHIVE_HANDLE                = 0
*   LOCAL_CAT                     = ' '
IMPORTING
   HEADER                        = TEXTHEADER
  tables
    lines                         = lines
EXCEPTIONS
   ID                            = 1

   LANGUAGE                      = 2
   NAME                          = 3
   NOT_FOUND                     = 4
   OBJECT                        = 5
   REFERENCE_CHECK               = 6
   WRONG_ACCESS_TO_ARCHIVE       = 7
   OTHERS                        = 8
          .
IF sy-subrc <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.

I checked the values while debugging & executed the FM with same values in SE37 which displays the correct results but in the program i am not getting any results.

regards

Sumit
