Reading data from B2 Cluster

1. Retrieving data from B2 cluster using Function module.

Function module name is - HR_FORMS_TIM_GET_B2_RESULTS

Sample Code -

*&---------------------------------------------------------------------*
*& Report  YTEST_B2_CLUSTER
*&
*&---------------------------------------------------------------------*
*&
*&
*&---------------------------------------------------------------------*

REPORT  ytest_b2_cluster.

TABLES: pernr.

infotypes: 0000, 0001.

DATA: lv_begda TYPE dats,
      lv_endda TYPE dats.

DATA: ls_tim_b2 TYPE hrf_tim_b2.

lv_begda = '20110101'.
lv_endda = '20110830'.
START-OF-SELECTION.
GET pernr.

  CALL FUNCTION 'HR_FORMS_TIM_GET_B2_RESULTS'
    EXPORTING
      pernr                 = pernr-pernr
      begda                 = lv_begda
      endda                 = lv_endda
    IMPORTING
      tim_b2                = ls_tim_b2
    EXCEPTIONS
      wrong_cluster_version = 1
      no_read_authority     = 2
      cluster_archived      = 3
      technical_error       = 4
      OTHERS                = 5.

END-OF-SELECTION.

2.  Retrieving data from B2 cluster using Import statement.

*--->>> INCLUDE rpc2b200 ( RPCnxxy0)
*--->>> n = 1, 2, 3 or 4 (for PCL1, PCL2, PCL3, PCL4)
*--->>> xx = cluster ID
*--->>> y = country grouping (0 for international otherwise country indicator T500L)

INCLUDE rpc2b200. ( so here we are using PCL2, B2 cluster and country key international )
TABLES: pernr, pcl2.
INFOTYPES: 0000, 0001.
DATA: lv_begda TYPE dats,
      lv_endda TYPE dats.
DATA: lit_saldo TYPE STANDARD TABLE OF pc2b5.
START-OF-SELECTION.

GET pernr.
  b2-key-pernr = pernr-pernr.
  b2-key-pabrj = '2011'.
  b2-key-pabrp = '05'.
  b2-key-cltyp = '1'.
  IF pernr-pernr EQ '00010673'.
    IMPORT SALDO FROM DATABASE pcl2(b2) ID b2-key.
    IF sy-subrc EQ 0.
      LOOP AT saldo. " saldo is a table in cluster b2
       APPEND saldo TO lit_saldo.
      ENDLOOP.
    ENDIF.
   ENDIF.
END-OF-SELECTION.


3.  Retrieving data from B2 cluster using Macro statement.

TABLES: pernr, pcl2, pcl1.*  Buffer definition
INCLUDE rpppxd00.
DATA: BEGIN OF COMMON PART.
INCLUDE rpppxd10.
DATA: END OF COMMON PART.

INCLUDE rpc2b200.  " Same as explained for Import statement

INCLUDE rpppxm00.  " all macro definitions
DATA: lit_saldo TYPE STANDARD TABLE OF pc2b5.

START-OF-SELECTION.

GET pernr.
  b2-key-pernr = pernr-pernr.
  b2-key-pabrj = '2011'.
  b2-key-pabrp = '05'.
  b2-key-cltyp = '1'.
  IF pernr-pernr EQ '00010673'.
** reset macro
    rp-init-buffer.
** import macro
    rp-imp-c2-b2.
    IF sy-subrc EQ 0.
      LOOP AT saldo.  " saldo is a table in cluster b2
       APPEND saldo TO lit_saldo.
      ENDLOOP.
    ENDIF.
  ENDIF.

END-OF-SELECTION.
