In XML Output the values of Number column tags are not displayed properly

Question

Hi,
Our Client have been using AR Invoice Print Program for a long time and it is heavily customized. Also they are using an old version of the RDF. So we have taken the latest version of the RDF (RAXINV.rdf) for Oracle Apps 11.5.10.2 by raising a SR and implement Client's old RAXINV.rdf into it.
All was ok, but when we are running the program, the XML Output did not generate properly. For the Q_INVOICE query (G_ORDER_BY, G_INVOICE and G_INV_TERM group), the value of some of the scaler number columns are not appeared properly. The tags are coming correctly, but the value is appearing as '*', instead of the correct value. We have checked in the RDF Level (By putting srw.message and check in the log file) that those columns are having proper value. So there is no issue with the RDF.
But because of the above mentioned problem, the some of the PDF output field values also is not generated correctly.
I think that because of the lexical parameters which was implementing the Q_INVOICE query (&COMMON_QUERY) this issue is coming. Because the issue is only in the Q_INVOICE query group (G_ORDER_BY, G_INVOICE and in G_INV_TERM group) not in any other query group.
There is no problem with the scaler character columns. The issue is only with the number columns.
Also we have checked that if we hardcode the value of the number columns in the above mentioned lexical parameter, this problem doesn't appear.
If we put TO_CHAR function to those number columns in the lexical parameter (COMMON_QUERY), then this issue get solved. But we can't do it because of performance issue and also Client won't approve it.
Please help.
With Thanks and Regards

I don't know how to read the code you pasted or I would have checked this myself.
Do your fields in the internal table reference dictionary objects or elementary types? If not using dictionary types, the column names will be blank by default. If you can't change your fields to be dictionary types, you can try this to change the column names:
I made a method inside my local class to add the names:
        call method set_colname
          EXPORTING iv_tab = alv_tab
                    iv_colid = 'xxxx'  "fieldname from the table
                    iv_stxt = text-t54
                    iv_mtxt = text-t55
                    iv_ltxt = text-t55.
METHOD set_colname .
  data:
          alv_cols type REF TO cl_salv_columns_table,
          alv_col type REF TO cl_salv_column.
  TRY .
*... Change fieldnames
        call METHOD iv_tab->get_columns RECEIVING value = alv_cols.
        call method alv_cols->get_column EXPORTING columnname = iv_colid RECEIVING value = alv_col.
        IF iv_stxt <> ''.
          CALL METHOD alv_col->set_short_text EXPORTING value = iv_stxt.
        ENDIF.
        IF iv_mtxt <> ''.
          CALL METHOD alv_col->set_medium_text EXPORTING value = iv_mtxt.
        ENDIF.
        IF iv_ltxt <> ''.
          CALL METHOD alv_col->set_long_text EXPORTING value = iv_ltxt.
        ENDIF.
   CATCH cx_salv_not_found.
  ENDTRY.
ENDMETHOD. "set_colname
