Phase 3: Preparations on Source Environment
Perform general and technical preparations in the source systems in accordance with your selected copy strategy. The amount of actions required here depends on the copy scenario chosen. The copy scenario also determines the impact (and most of all the downtime) imposed on the source landscape.
3.1 – Prepare source systems
3.2 – Save configuration information
Not required but is always good to have – Prepare SMQR, SMQS, SM59, BD54 as images or text files.
3.3 – Stop productive operation in source systems
Applicable for a scenario Minimum Risk – Before shutting down the source systems in a later step, stop any user or batch job activity to allow for the communication queues to empty and for additional preparations to be taken.
3.4 – Complete message processing in source landscape
Required with SAP XI/PI/PO for all messages in status scheduled for outbound processing
3.5 – Disable communication between source systems
3.6 – Shutdown source landscape (Optional depending on restore and roll forward method)
Shut down the source systems to provide a stable and consistent state for copying.
3.7 – Backup the source landscape
(Optional depending on restore and roll forward method)
3.8 – Prepare any other systems outside the source landscape
Step 3.2: Empty the delta queue of the connected SAP source systems
Execute all delta infopackages two times, to clean up the delta queue in the source system. This is needed, because BDLS cannot rename the still available LUW-s in the qRFC queue.
Step 3.3: Stop productive operation in the original BW system
SAP NetWeaver 7.0: Stop all daemons for real-time data acquisition in transaction RSRDA.
SAP NetWeaver 7.2: Execute report RS_SYSTEM_SHUTDOWN to stop process chains and real-time data acquisition.
This has to be done before locking the RFC users and before stopping and disabling the other background jobs, e.g. by executing report BTCTRNS1.
3.6 – Shutdown source landscape
When shutting down the source landscape, make sure that also all external CRM landscape components are shut down. Make sure that e.g. no CRM Internet Sales servers are running during the copy and no Mobile Client users are trying to connect to the CRM server.
3.1 – Prepare source systems
You should check the data consistency between APO DB and the liveCache (known as internal consistency) and the data consistency between the APO DB and the R/3 system (known as external consistency). Please refer to SAP note 425825 for R/3 and APO.
Ensure that all open, pending issues that have been identified in the Core Interface (CIF) queues have been resolved.
Locks all users including NON DIALOG users
When copying a landscape including an SAP XI system, all messages with status scheduled for outbound processing must be processed before doing the copy!
