Hello,

• The name of database table

• The name of variant.

The program have to download data from this table with the variant specified and transfert the result to a server file.

Anybody know a FM wich takes the name of table and the variant in input and generate the data correspending of this on output.

Hi,

I suppose by "variant" you mean a WHERE condition to specify which data you want.

I don't know whether there is a standard function for this, but the thing is very easy to write. Here is a sample report (with just the basics, you'll have to add code to scure the server file, etc.):

REPORT  zloadtab NO STANDARD PAGE HEADING.

PARAMETERS:
  p_table   TYPE tabname OBLIGATORY,
  p_where   TYPE char255,
  p_file    TYPE char128 LOWER CASE OBLIGATORY.

DATA:
  reftab      TYPE REF TO data,
  condition   TYPE string,
  file_error  TYPE string.

FIELD-SYMBOLS:
  <t>         TYPE ANY TABLE,
  <line>      TYPE ANY.


START-OF-SELECTION.
  TRY.
      CREATE DATA reftab TYPE STANDARD TABLE OF (p_table).
      ASSIGN reftab->* TO <t>.
      condition = p_where.
      SELECT * FROM (p_table) INTO TABLE <t> WHERE (condition).
      IF sy-dbcnt = 0.
        MESSAGE s002(sy) WITH 'No qualifing records found'.
        STOP.
      ENDIF.
    CATCH cx_sy_dynamic_osql_semantics.
      MESSAGE i002(sy) WITH 'Wrong syntax in WHERE clause'.
      STOP.
    CATCH cx_sy_create_data_error.
      MESSAGE i002(sy) WITH 'No such table exists'.
  ENDTRY.
  OPEN DATASET p_file FOR OUTPUT IN TEXT MODE
                      ENCODING DEFAULT MESSAGE file_error.
  IF sy-subrc <> 0.
    WRITE: / 'Cannot open:', p_file, / file_error.
    STOP.
  ENDIF.
  LOOP AT <t> ASSIGNING <line>.
    TRANSFER <line> TO p_file.
  ENDLOOP.
  CLOSE DATASET p_file.

Have fun,
