System refresh is nothing but copying an SAP system to another.
Let us say the system from which copy is being done is called as source system and system in which data to be copied as target system.
System refresh activity comprises of following 3 phases
- Pre refresh activity
- Refresh activity (Database restoration)
- Post refresh activity
Pre-refresh Activity:
Before performing system refresh, following steps need to performed
1) Export of user master and authorizations from all SAP clients on the target system (SCC8)------CLICK HERE
This step is required because once the source system data is replaced in the target system, the user and authorization details of target system will be overwritten by source system user master. So, in case we need to retain target system user master, we have to take backup of the same using SCC8 tcode.
2) Please take snapshots of
- Client settings (SCC4)
- Logon groups (SMLG)
- Processing groups (RZ12)
- AL11, SE03 and SM61
- Printer details (SPAD)
- Operation modes (RZ03, RZ04 and SM63)
- RFCs (SM59)
- Partner profiles (WE20) and ports (WE21)
- Logical systems (BD54)
- Services that are active (SICF)
These screenshots are to be captured because after system refresh, we need to check and maintain the same settings in target system
3) Using SE01 transaction, create transport request forbacking up of AL11, SE03, SMLG(Logon Groups), RZ12(Processing Groups),SM59(RFC’s), SM69, SPAD, SM61, RZ03---------------CLICK HERE
Refresh activity (Database restoration)
1) Please stop the target sap system and handover to database team
2) Database team will restore the data from source system to target system and validate
3) Once everything is fine, database team will handover system to SAP Basis team
2) Database team will restore the data from source system to target system and validate
3) Once everything is fine, database team will handover system to SAP Basis team
Post refresh activities:
1) Disable batch processing (by setting batch work processes as 0 at Os level)
5) Delete/recreate TMS for target system using SE06
6) Configure SAP transport system (using STMS)
7) Import user master for all clients (which was done as part of pre-refresh steps)
8) Import transports related to AL11, SE03, SMLG, RZ12, SM59, SALE and SM69
backup (which was done as part of pre-refresh steps)
9) Execute BDLS transaction
12) Perform spool consistency check using SP12 transaction
13) Delete old update records using SM13 transaction
14) Delete/Reorganize transaction RFC’s using SM58 transaction
15) Delete batch job logs by executing RSBTCDEL report using SE38 transaction
16) Delete Old spool requests by executing RSPO0041 report using SE38 transaction
17) Create/modify necessary partner profiles using WE20 transaction
18) Modify necessary ports using WE21 transaction
19) Perform mail configuration using SCOT transaction
20) Delete old mail related entries using SOST transaction
21) Execute SGEN transaction or run RSGENINVLAS report (no variant is required) using
SE38 transaction
22) Make necessary services active through SICF transaction
