HOW TO EXTRACT DATA VIA OPEN HUB TO A CUSTOMER DEFINED LOGICAL FILENAME

2004 SAP AMERICA, INC. AND SAP AG 1

1 Business Scenario With the help of the OPEN HUB and by using user-defined logical filenames, you can save data on the application server. It is assumed that the logical filename has already been created using the FILE transaction.

2 Introduction This How To paper describes how the open hub functionality can be enhanced with the use of logical filenames with 2 modifications and the creation of an append structure for table RSBFILE.



The Step By Step Solution

1. Enhancement of Table RSBFILE 1. Start Transaction SE11

Database table: RSBFILE Click: DISPLAY Comment: Please take a look to chapter 3 “Upgrade to BW 3.5 Patch 1+”

2. Append Structure of table RSBFILE Click: Append Structure



3. Type in the technical name of the structure-append.

4. Type in the Description: Append for logical filename Add the components and Component types: Component 1: ZZFILEINT Component type 1: FILEINTERN Component 2: ZZDOTNETLS Component type 2: LOGSYS Check and activate the APPEND Ignore the warnings.



2. Define CLASS ZCL_RSB_FILE_LOGICAL Please import the added Transport. The Transport includes the class ZCL_RSB_FILE_LOGICAL. Transport:

K902312.qb8 R902312.qb8 Please check and activate the imported class.

3. Modify Class CL_RSB_DEST 1. Goto Transaction SE24

DISPLAY Object type: CL_RSB_DEST

2. Double click on the Method: GET_OBJECT_REF_INT



Change line: 19 from: DATA: l_r_file_applsrv TYPE REF TO cl_rsb_file_applsrv. to: DATA: l_r_file_applsrv TYPE REF TO ZCL_RSB_FILE_LOGICAL. ) DATA: l_r_file_applsrv TYPE REF TO CL_RSB_FILE_LOGICAL. Example for modification: see * nächste Zeile für Michael Hoerisch geändert METHOD get_object_ref_int . DATA: l_desttype TYPE rsdesttype, l_appserver TYPE rsbappserver. SELECT SINGLE desttype INTO l_desttype FROM rsbohdest WHERE ohdest = n_dest AND objvers = rs_c_objvers-active. IF sy-subrc <> 0. SELECT SINGLE desttype INTO l_desttype FROM rsbohdest WHERE ohdest = n_dest AND objvers = rs_c_objvers-modified. ENDIF. CHECK sy-subrc = 0. CASE l_desttype.

DATA: l_r_file_applsrv TYPE REF TO ZCL_RSB_FILE_LOGICAL. CREATE OBJECT l_r_file_applsrv EXPORTING i_dest = n_dest

i_objvers = i_objvers



3. Double click on the Method: CHANGE_PARMS

Replace line 23: from: data: l_r_file_applsrv type ref to cl_rsb_file_applsrv.

to: data: l_r_file_applsrv type ref to zcl_rsb_file_logical. Example for modification: see * nächste Zeile für Michael Hoerisch geändert method change_parms . data: l_s_vdest type rsbo_s_vdest. l_s_vdest = i_s_vdest. * l_s_vdest-objvers = rs_c_objvers-new. l_s_vdest-desttype_int = get_desttype( l_s_vdest ). if not p_r_vers_n is initial. * check: re-instantiation necessary ? data: l_s_vdest_old type rsbo_s_vdest. call method p_r_vers_n->get_info importing e_s_vdest = l_s_vdest_old. if l_s_vdest-desttype_int ne l_s_vdest_old-desttype_int. clear p_r_vers_n. clear p_r_vers_m. clear p_r_vers_a. endif. endif. if p_r_vers_n is initial. case l_s_vdest-desttype_int. when rsbo_c_desttype_int-file_applsrv. * nächste Zeile für Michael Hoerisch geändert *\ data: l_r_file_applsrv type ref to cl_rsb_file_applsrv. data: l_r_file_applsrv type ref to zcl_rsb_file_logical. create object l_r_file_applsrv exporting i_dest = n_dest



i_objvers = rs_c_objvers-new.
