Custom RFC

former_member290321 — Thu, 26 Jun 2008 16:18:44 GMT

I am not a ABAP developer but working on MS SQL 2005 BI side but I need something like this from ECC 6.0

I will request if anyone can guide me building a custom RFC with simple select statment

i.e.

select * from Table_Name

where Field_Name between @StartDateofLastMonth and @EndDateofLastMonth.

The aforesaid select statment will get the calculated startdate and enddate from sap system date.

where as i have to give @Table_Name and @Field_Name from my end as variable...

One more favor where i can get sample RFC for the aforesaid.

Hi,

if it is really that simle you may use function module RFC_READ_TABLE. Reads any table of the system.

Unfortunately the documentation is available in German only. But the interface explains it sufficiently:

*"  IMPORTING
*"     VALUE(QUERY_TABLE) "table name
*"     VALUE(DELIMITER)   "delimeter for output - default is space
*"     VALUE(NO_DATA)     "retrieve field list only
*"     VALUE(ROWSKIPS)    "skips some rows - no ned to use so far
*"     VALUE(ROWCOUNT)    "max. no of selected rows
*"  TABLES
*"      OPTIONS           "WHERE CLAUSE (ABAP OPEN SQL )
*"      FIELDS            "First 30 characters for desired output fields 
*"      DATA              "selected data sepearated by DELIMETER

example:

FORM data_select  USING    pp_matnr TYPE matnr.
    CONSTANTS c_delim LIKE  sonv-flag VALUE '|'.
    DATA: lt_options TYPE STANDARD TABLE OF rfc_db_opt WITH HEADER LINE,
         lt_data  TYPE STANDARD TABLE OF tab512 WITH HEADER LINE.

    DATA: lt_split TYPE STANDARD TABLE OF
                                       catpaval WITH HEADER LINE.
    FIELD-SYMBOLS <l_value>.
    REFRESH: lt_options, lt_data.

    CONCATENATE '''' pp_matnr '''' INTO lt_options.
    CONCATENATE 'MATNR EQ' lt_options INTO lt_options
            SEPARATED BY space.
    APPEND lt_options.
    CONCATENATE '''' p_valdat '''' INTO lt_options.
    CONCATENATE 'AND VALTO GE ' lt_options INTO lt_options
            SEPARATED BY space.
    APPEND lt_options.

    APPEND LINES OF gt_options TO lt_options. "filled elsewhere
    

    REFRESH lt_data.
    CALL FUNCTION 'RFC_READ_TABLE'
      DESTINATION gv_dest          "RQ 2429143 <ins>
*      DESTINATION p_logsys        "RQ 2429143 <del>
      EXPORTING
        query_table                = 'DGTMD'
   delimiter                  = c_delim
*   NO_DATA                    = ' '
*   ROWSKIPS                   = 0
*   ROWCOUNT                   = 0
      TABLES
        options                    = lt_options
        fields                     = gt_fields
        data                       = lt_data
    EXCEPTIONS
      table_not_available        = 1
      table_without_data         = 2
      option_not_valid           = 3
      field_not_valid            = 4
      not_authorized             = 5
      data_buffer_exceeded       = 6
      OTHERS                     = 7
                 .
    IF sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
    ENDIF.
    .....
    ......
  ENDFORM.                    " data_select

Have fun,

Holger

The problem with RFC_READ_TABLE is that i can't use variable in @OPTIONS from MS SQL server side.

So I can't auto my package to import data on monthly basis.

I can't use this in filter in@OPTIONS

i.e.

@OPTIONS = 'where ce1lsc0.budat between @startdateoflastmonth and @lastdateoflastmonth '

as you fill the options in your external system, you can calculate the two dates there - format has to be YYYYMMDD. Can't see any problem.

Kind regards,
