Changing the file name n Flat file Extraction

Question

Hi,
Currently i am using flat file extraction for my forecast data and i am sending the file through application server.
I have created directory successfully and now everyday morning i receive a file thru FTP server with name 20060903.csv and this name is based on one field in my flat file data.  ex. /interface/asf/20060903.csv
During mid off month we have cut off date, and this cut off date varies for each month. During this time file name changes in the FTP and a file with different name i.e 20061002.csv will be existing in the application server.
Now in the infopackage i also need to set the deletion settings like if the file name is same delete the previous requests. I could achieve this if i could get the file name changed.
Lets say if i am not chnaging the file name how do i set deletion condition, like it should not delete if the field(scenario) changes. ie from 20061002 to 20061101. I should have only one file for 20061002 and one file for 20061101 etc... If the scenario is same it should delete.
Any one kindly advise. Very urgent and critical.
Tks & regards,
Bhuvana.

Hi Bhunva,
Try the following abap code in routine under External data tab in infopackage.
data: begin of i_req occurs 0,
      rnr like RSICCONT-rnr,
      end of i_req.
select * from RSICCONT UP TO 1 ROWS
                  where ICUBE  = <datatargetname>
                  order by TIMESTAMP descending.
  i_req-rnr = rsiccont-rnr .
  append i_req.
  clear i_req.
endselect.
loop at i_req.
  select single * from RSSELDONE where RNR eq i_req-rnr and
                                   filename = p_filename.
  if sy-subrc = 0.
    CALL FUNCTION 'RSSM_DELETE_REQUEST'
      EXPORTING
        REQUEST                    = i_req-rnr
        INFOCUBE                   = <datatargetname>
      EXCEPTIONS
        REQUEST_NOT_IN_CUBE        = 1
        INFOCUBE_NOT_FOUND         = 2
        REQUEST_ALREADY_AGGREGATED = 3
        REQUEST_ALREADY_COMDENSED  = 4
        NO_ENQUEUE_POSSIBLE        = 5
        OTHERS                     = 6.
    IF SY-SUBRC <> 0.
      MESSAGE ID sy-MSGID TYPE 'I' NUMBER sy-MSGNO
          WITH sy-MSGV1 sy-MSGV2 sy-MSGV3 sy-MSGV4.
    else.
      message i799(rsm1) with i_req-rnr 'deleted'.
    ENDIF.
endif.
let me know if you get any problem in this logic.
