AS_API_READ problem in archiving

Question

Dear experts,
Recently i worked on one of archiving retrieval scenario where standard infoobject is SAP_FI_DOC_002.
I fetched data from BSEG,BKPF,WITH_ITEM using archiving FMs ARCHIVE_READ_OBJECT,ARCHIVE_GET_NEXT_RECORD.
Everything is going fine from retrieval point of view.Problem is performance.
Reason why its happening is as below:
CALL FUNCTION 'AS_API_READ'
    EXPORTING
      i_fieldcat                      = 'SAP_FI_DOC_002'
      i_selections                    = gt_selection[]
*   I_OBLIGATORY_FIELDS             =
*   I_MAXROWS                       =
   IMPORTING
      e_result                        = gt_result.
* EXCEPTIONS
*   PARAMETERS_INVALID              = 1
*   NO_INFOSTRUC_FOUND              = 2
*   FIELD_MISSING_IN_FIELDCAT       = 3
*   OTHERS                          = 4
  IF sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
  ENDIF.
In this FM ,if i provide selection field say 'BUKRS' 'GJAHR' 'BUDAT' 'BSTAT' .
Since only BUKRS GJAHR BUDAT lies in fieldcatalog of infostructure and BSTAT is an optional field,
so i get all possible combination of BSAT though i may be requiring less records.
It also adds to performance issue as i am not able provide correct index criteria.
This is a simple example.In my overall report i am facing this issue at many places where whole
data is getting retrieved.
How can i solve this problem. ?
I do not want to convert SAP_FI_DOC_002 to Z_SAP_FI_DOC_002 and do activation or deactivation because
i feel using a custom infostructure with standard reports atlast may invite other issues.
How to deal with this in abap . ?

Hi,
File adapter has the functionality which support the empty file handling.
Handling of Empty Files
Specify how empty files (length 0 bytes) are to be handled.
○ Do Not Create Message
No XI messages are created from empty files.
The files are processed according to the selected Processing Mode.
For example, if the processing mode is Delete, empty files are deleted in the source directory.
○ Process Empty Files
XI messages are created with an empty main payload.
The files are processed according to the selected Processing Mode.
○ Skip Empty Files
No XI messages are created from empty files.
Empty files are skipped and remain in the source directory.
