'TEXT_CONVERT_XLS_TO_SAP' and i have collected data into a internal table , till here i am able to get data correctly , now i hae to upload this data into a custom table .
the flat file is having  6 fields and the custom table is having
8 fields , for uploading the data into this custom table from the internal table where i have collected above iam getting problem . Actually iam using a modify statement to update the custom table .
the flat file which i have collected into the internal table is as below :
  IDNo.     Name     Date      Location   Designation  Dept
  101       Raja      4/12/2007  Delhi      Manager      HR
  102       James    4/12/2007  Delhi      Clerk          HR
Custom table  is having the below fields
IDNO.  Name  Date  Location Designation  Dept   Manager
101                                                                   Raja
now when i run the program iam getting the problem   while usign the modify statment is the ID no which is already having
a record as  IDno = 101  and manger = Raja.......with the other fields   name , date, location,designation and dept as blank.
if i want to fill this fields from my flat file the modify statment
just filling all the fields  for the ID no = 101  and manager field which already having Raja as being overwritten by space .....
becasue this field is not being there in the flat file.

The flat file is having with the below structure
TYPES: BEGIN OF t_emp_data,
          IDNO(11) TYPE c,
         Name(13) TYPE c,
         Date(20) TYPE c,
          Location (40) TYPE c,
         Designation(40) TYPE c,
         Dept(40) TYPE c,
         end of t_emp_data.
The Custom Table(ZEMP_DATA) is having with the below structure
TYPES: BEGIN OF t_emp_data_table,
          IDNO(11) TYPE c,
         Name(13) TYPE c,
         Date(20) TYPE c,
          Location (40) TYPE c,
         Designation(40) TYPE c,
         Dept(40) TYPE c,
         Manager(20) type c,  -- this is the extra field in table
         end of t_emp_data_table.
data :
it_empdata TYPE STANDARD TABLE OF t_emp_data,
it_empdata_tmp TYPE STANDARD TABLE OF t_empdata_tmp,
wa_empdata_tmp  type t_empdata_tmp,
wa_empdata type t_emp_data.
loop at it_empdata into  wa_empdata.
  move-corresponding  wa_empdata to   wa_empdata_tmp.
  modify ZEMP_DATA  from  wa_empdata_tmp .
endloop.
could any one please let me know what i have to do inorder to not get the manager field data not being overwritten with the modify statment , for the IDNo. 101  . I want the data which is already ( manager = Raja) shouldnt not be get overwritten with Space.

Hi,
use a slect statement before
"move-corresponding wa_empdata to wa_empdata_tmp."
select manager
from ztable
into wa_empdata_tmp-manager
where id = 100.
