Creating a Copy of an R/3 Source System 

Procedure

  1. Replace a BW source system with another system with the help of a database copy or a client copy.

    2. Replace the source test system with a copy of the source production system.

  2. In the source system, select tools ABAP Workbench overview data browser and enter RSBASIDOC.
  3. Select table, table contents.
    1. If entries are available, then connections between the source system and other systems still exist. You have to delete these connections. To do this note down the entries for the fields RLOGSYS and SLOGSYS that belong together.

      2. Using Tools ® ABAP Workbench ® Development ® Function builder call up the function module RSA_BIW_DISCONNECT in single test.

      Enter the name of the current system pairs by filling the parameter I_BIW_LOGSYS with RLOGSYS and the parameter I_OLTP_LOGSYS with SLOGSYS. Do not fill the parameter I_FORCE_DELETE. Repeat this process for all entries in the table RSBASIDOC.

      The obsolete system connections are deleted.

    2. If table RSBASIDOC does not contain any entries then step 3 a) cannot be carried out.
  1. In the source system Implementation Guide, select Cross-application components ® Distribution (ALE) ® Basic Settings ® Set up logical system ® Assign logical system to client. Make sure that the same logical system name is assigned to the copied client as before the copy. BW recognizes the source system under this logical name.
  1. In the Business Information Warehouse, select Tools ® Administration ® Management ® Network ® RFC Destinations.
  2. Select Edit ® Change for the logical name of the source system destination and make a note of the user specified in the maintenance screen.
  3. Repair the connection that has been destroyed by the copy by restoring them in the source system. Restoring the source system is a requirement for data extraction from this source system after the copy.

To do this select Source system tree ® Your source system ® Context menu (right mouse button) ® Restore in the BW Administrator Workbench Modeling. You get to the Creating an R/3 Source system screen. Enter the required data. For user in the source system enter the user that you gave in step 6.

Result

The source system is recreated, the relevant communication parameters are matched and a Metadata upload is carried out in BW. By restoring the source system you can extract data from the copied system after the copy and transfer it into BW.
