In the newly  copied systems, subsequent technical actions and post-installation steps  must be performed – most importantly to prevent the target environment from  interfering with the production systems. This includes changing system  connections and other cleanup activities, but also renaming and  reconfiguring to meet the requirements of the target landscape. Installation  of additional components that are not copied is usually done in this phase also.

Generic

6.1 – Execute  follow-up activities on OS and DB level

Please note that during installation of the target system with SWPM.

BW  Specific

Phase 6: Final  Activities in Target Environment

Step 6.4: Correct  RFC destinations

Delete or modify  the RFC destinations that point to the original systems. Ensure that an RFC  destination exists with the new logical name (which will be assigned in step  6.7) in every connected BW or SAP source system. Change the hosts in the  appropriate RFC destinations so that they refer to the correct system. See  Note 524554.

Step 6.7: Execute  Transaction BDLS if you want to rename a system

If you want to  rename one or more of the copied systems, execute transaction BDLS both in  the client you wish to rename and in all connected SAP source systems. No  other activities (for example, execution of Administrator Workbench / Data  Warehousing Workbench (RSA1)) can be performed in the system during  conversion!

Read Notes 121163  and 369758 for details about transaction BDLS.

Step 6.8: Perform  BW-specific adaptations

The following  steps are necessary if the logical system name has been changed:

Execute the  following task on the BW system and the SAP source systems.

Reactivate all  partner profiles that contain the new logical system name after renaming.  Execute transaction WE20 to reactivate the partner profiles. Choose  “Partner type LS (logical system)”, enter the logical system name  of the partner on tab “classification”, change the partner status  from “I” (inactive) to “A” (active), and save.

Execute the  following tasks on the BW system:

Update logical  system descriptions in RSA1. For each SAP source system that was converted  using BDLS, change the description to match the new logical system name.

Reset generation  flag for ODS activation programs. Call transaction RSSGPCLA and highlight  program class RSDRO_ACTIVATE. Click #set status# and #OK#. Repeat for  program class RSDRO_EXTRACT and RSDRO_UPDATE

Not required – If  you are using a BW Accelerator, refer to SAP Note 1146983 for further  instructions.

Execute the  following step if the host has been changed:

If you are using  BI Planning, adjust the server name of the BI Enqueue Server in the  administration transaction RSPLSE. For details see Note 996238.

Reset RFC  destination for process chain transport postprocessing. Use transaction  RSTPRFC to correct the host.

Step 6.9: Copying  BWREQARCH archives

In case request  information were already archived with BWREQARCH in the original system,  then after the copy the archives files must be copied to a place, where they  are accessible for the target system. The best solution for this would be an  “XCOPY” on OS level. With this action several serious problems can  be avoided, such as the problems from the KBA 1812238.

Step 6.16:  Restart productive operation in the target BW system

SAP NetWeaver  7.0: Restart daemons for real-time data acquisition in transaction RSRDA.

SAP NetWeaver  7.2: Execute report RS_SYSTEM_SHUTDOWN to restart process chains and  real-time data acquisition.

This has to be  done after unlocking the RFC users and after configuring the number of  background work processes.

CRM  Specific

6.8 – Do  solution-specific adjustments

Use the report ZSCAN_LOGSYS to check if there are still tables containing the logical        name of the source system. For more information see SAP note 564435.

Adjust the settings in the tables CRMCONSUM and CRMRFCPAR in the copied connected backend system.

6.9 – Import  saved information from step 2.1

Adjust the connection to backend systems in transaction SMOEAC

Restore CRM middleware parameters in table SMOFPARSFA

6.14 – Load or  initialize data in additional components

For ecommerce and  mobile scenarios please recheck  SAP  Note 886104 – System Landscape Copy for SAP CRM

APO  Specific

6.2 – Prevent  accidental start of processes on target system

If a homogeneous  system copy was performed via the database restore method the liveCache  connections in the target system direct to the liveCache of the source  system. To prevent that jobs running in the target system change data in the  liveCache of the source system you should:

Disable the batch jobs in the target system before starting the target SCM system

Apply note 1015489 in order to reset the SAP system ID (SID) in liveCache. (The liveCache stores the SID of the application server from which the first call arrives. All subsequent calls are accepted only if they are triggered from the same SAP system, i.e. provide the same SID.)

If SWPM is used  to perform a heterogeneous system copy it deletes the liveCache connections  during database migration. Therefore, the target system cannot access  accidently the source liveCache. Note 1015489 has not to be applied in that  case because the SID information is not migrated into the target system via  SWPM.

6.3 – Start  target system

Start the SCM  server and the corresponding SAP ERP Backend System in the target  environment.

Ensure that in  the target SCM system no users are logged in, no batch jobs are running or  planned and that the CIF queues are stopped, i.e. no application data should  be modified.

6.4 – Adjust  system connections

The following  configurations establish communication between the core ERP system and the  SCM server, APO liveCache and APO Optimizer.

In the new system  environment, use transaction SM59 to check the destination entries and  maintain them as follows:

ERP Connections

a) Backend  System/Component systems (hostname/Logon data)

b) SCM Server  (hostname) for each production client

Note: If you are going to convert  logical system names in step 6.7, the names of the RFC destinations need to  be adapted as well (since the SCM communication model relies on identical  names).

TCP/IP  Connections

RFC Destination  Type T to  APO Optimizer:

          OPTSERVER_CMT01  CTM Optimizer 01 (Capable-To-Match)

          OPTSERVER_DPS01  DPS Optimizer 01 (Detailed Prod  Scheduling)

          OPTSERVER_SNP01  SNP Optimizer 01 (Supply Network Planning)

          OPTSERVER_ND101  ND    Optimizer 01 (Network Design)

          OPTSERVER_SEQ01  SEQ Optimizer 01 (Sequencing)

          OPTSERVER_VRS01  VRS Optimizer 01 (Transportation Planning  and Vehicle scheduling)

          Additionally check and maintain  the Gateway destination data within these RFC destinations above.

Adapt connections  to liveCache (only when using external liveCache):

In the target SCM  system, establish or change the liveCache connections (table DBCON) via  transaction LC10 as follows:

          a) In the initial screen of the  transaction, enter LCA, then choose the key    “liveCache:Create/change connection” respectively  “Integration” (Ctrl+F4) with  newer releases. Enter the name of the liveCache server of the target system  there, then save.

          b) Repeat the same procedure for  the liveCache connection LDA, if this connection is set up. (The connection  LDA is only required for the APO application ATP.)

          c) As of SCM 5. 0, repeat the  same procedure for the liveCache connection LEA, which is used for the lock  server.

6.7 – Convert  Logical System Names

Transaction BDLS  must be run for the following logical system names:

In the SAP R/3  backend system:

a)  Logical system for SCM

b)  Logical system for OLTP

In the SAP SCM  system:

a)  Logical system for SCM

b)  Logical system for OLTP

Transaction BDLS  must be started for every client on the backend systems.

On the SCM server  you can check the logical system names using path SPRO-> IMG->  Basis-> Distribution (ALE)-> Sending and Receiving Systems ->  Logical Systems-> Assign Client to Logical Systems

Note: After  converting logical system names, the names of corresponding RFC destinations  need to be adapted as well (since the SCM communication model relies on  identical names).

6.8 – Do  solution-specific adjustments

Before you  release the system to the users, it is important to do the following steps.  More details on each of these steps are given below.

              1) Check, if you need to  change the logical system name in /SAPPAPO/ORDMAP to the target system.

              2) If you need to rename the  user ‘SAPR3’ to ‘SAPEL1’ (for example) after you did the Homogeneous  liveCache copy please run the steps outlined in point 2 below.

              3) Adapt the logical system  names in the report variants /SAPAPO/CIFSTOPQUEUES, /SAPAPO/CIFSTARTQUEUES

              4) Check variants of BW  Reports RSIMPCURR, RSIMPCUST – if required.

              5) Maintaining the Business  System Group on SAP SCM Server

              6) Maintaining the Business  System on SAP SCM Server

              7) Customizing the Optimizer  Destination entries

              8) Set SCM Target System on  SAP R/3 OLTP System

              9) Adapt table CIFRFCDES

              10) Perform adaptations for  F&R SCM 5. 0

              11) For SCM 5. 1, reset the  SCM system name in liveCache

              12) Run report for additional  update after system copy

1.Adaption of logical system in liveCache table /SAPAPO/ORDMAP:a.As of release SCM 7.0 SP12, SCM 7.01 SP09, SCM 7.02 SP05 and higher:i.Use report /SAPAPO/OM_ORDMAP_CONV_LOGSYS to adapt the logical system.

b.Up to release SCM 5.1, SCM 7.0 SP11, SCM 7.01 SP08, SCM 7.02 SP04:i.when using an external liveCache:1.To adapt the liveCache table /sapapo/ordmap, you need to open a command prompt on          the liveCache server and start xquery. Alternatively you could use SQL Studio.

Enter:  username/password/system name (sapr3/../LC-Target)

Command:  select LOGSYS, count(*) from “SAPR3″.”/SAPAPO/ORDMAP”  group by logsys

For  each LOGSYS that is displayed, the same mapping / changes have to be done as  in BDLS. For exampleM001 =>M001

Command:  update “SAPR3″.”/SAPAPO/ORDMAP” set  logsys=’M001’where logsys=’M001′

This  will change the logical system name in /sapapo/ordmap to the target system.

1.Applicable only        if SAP HANA is NOT the APO database:a.If required,        and you want to rename the user ‘SAPR3’ to ‘SAPEL1’ after you did the        Homogeneous liveCache copy, you must complete the following steps:

Stop  liveCache in the LC10 transaction;

Start  liveCache with the command line in sm49, tool ‘dbmcli’: -d EL1 -n -u control,    db_warm

run  the SQL statement as ‘SUPERDBA’ user & check that ‘SAPEL1’ user is  listed:

select  * from domain.users

If  yes, run the SQL statement in sm49, tool ‘dbmcli’: -d EL1 -n -u control,-uSQL superdba,admin  sql_execute DROP USER SAPEL1

run  the SQL statement & check that ‘SAPEL1’ user is NOT listed:

select  * from domain.users run  the SQL statement in sm49, tool ‘dbmcli’: -d EL1 -n-u  control,-uSQL superdba,admin sql_execute rename user SAPR3  to SAPEL1

(link:  http://www.sapdb.org/7.4/htmhelp/48/f0dab7225811d3a97d00a0c9449261/content.htm)

run  the SQL statement in sm49, tool ‘dbmcli’: -d EL1 -n-u  control,-uSQL sapel1,sap

sql_execute  select * from domain.users

Run  the SQL statement as SAPEL1 user:

sql_execute  select * from tables where owner=’SAPEL1′

Run  the SQL statement as SAPEL1 user:

select  LOGSYS, count(*) from “SAPEL1″.”/SAPAPO/ORDMAP” group by  logsys reset the LCA, LDA and LEA connection to the Standard liveCache user  SAPEL1 ( pwd ‘sap’ )

To  make sure that the lcinit script works with the correct user ‘SAPEL1’ you  should run the commands to check the liveCache user in the upc container:

In  a dbmcli session (e.g. in transaction LC10 )

>  sql_execute user-type=SAP select user from dual

Should  return this user.

When  an error returns ( unkowen user/password ), then no user is set.

To  set the ‘SAPEL1’ user run:

dbmcli  -d EL1 -n-u control,user_sap sapel1,sap  (please see the note 616555 for more details ) in a dbmcli session. This  sets the new user in the upc container.

After  that the above command should return sapel1.

Restart  the liveCache in transaction LC10.

1.If you use the        reports /SAPAPO/RCIFQUEUECHECK,/SAPAPO/RCIFINQUEUECHECK for queue        monitoring and reports for stopping or starting of outbound queues and        /SAPAPO/CIFSTOPQUEUES, /SAPAPO/CIFSTARTQUEUES it is important that you        adapt the logical system names in the report variants.

1.If the BW        reports RSIMPCURR, RSIMPCUST are used, it is important that you check        the variants of these reports.

1.SAP SCM Server:        Maintaining the Business System Group (BSG).

This  step is a prerequisite for the successful integration of a multiple system  infrastructure. The BSG is maintained in the Implementation Guide APO –  Implementation Guide-> Advanced Planner and Optimizer (APO)-> Basis  Settings-> Integration-> Business System Group.

Alternatively  you can call transaction /SAPAPO/C1 or C2

Check  the distribution definitions and BSG assignments:

Table  /sapapo/cifdistr

You  can find these via:

SPRO  -> APO -> Basis Settings -> Integration -> Publication ->  Maintain distribution Definition -> Business System Groups -> Maintain  … delete the old entries as required:

Do  not rename the Business System Group, because, for example, material  master-tables are stored with the Name of the BSG.

Since  the logical systems, which are assigned to the BSG, are changed by BDLS  (step 6.7), there is no need to modify the name of the BSG.

1.SAP SCM Server:        Maintaining the ‘Business System’

The  Business System is defined in IMG: Extended Warehouse Management ->  Interfaces -> ERP Integration -> General Settings -> ‘Define Own  Business System’ or ‘Define Business System’.

Do  not rename the Business System, because it is stored in some transaction  data like EWM deliveries. There is no report available for a conversion of  the transaction data.

Since  the logical system, which is assigned to the business system, is changed by  BDLS (step 6.7), there is no need to modify the Business System name.

This  restriction is mainly applicable to EWM or SNC.

1.Customizing the Optimizer Destination Entries:

              1. Log on to the SAP SCM  server.

              2. Call transaction SIMGH.

              3. Expand the SAP APO  Customizing tree:

–  APO Implementation Guide-> Advanced Planner and Optimizer (APO)->  Basic Settings-> Optimization    -> Basic Functions

Then  call the function  “Maintain  Master Data for Optimization Server”.

Please  check and maintain if necessary the Optimization Server Master Data  regarding the existing and active RFC destinations (TCP/IP Connections  above).

1.SAP R/3 OLTP      System: Set APO Target System

To  enable the successful setup of communication between R/3 and APO, the  appropriate target system for this data channel must be installed in the  definition of the RFC destination.

Install  a valid operation mode at the same time.

For  executing that function call transaction CFC1 or call the following CIF  menu:

For  releases 4.6B on:

From  release 4. 6B, the CIF menu is called up via the SAP menu (SAP Easy Access).  Choose SAP Menu-> Logistics-> Central Functions-> Supply Chain  Planning Interface-> Core Interface Advanced Planner and Optimizer. Then  choose Settings-> Target Systems.

The  screen Change View “Target Systems and Operation Modes: Overview”  appears.

Maintain  the APO Release.

This  table controls the downward compatibility of the APO Core Interface. As a result, different SAP APO release levels can be addressed using the R/3  Plug-in version PI 99. For executing that function call transaction NDV2 or  choose the following path in the SAP menu:

As  of Release 4.6B:

Logistics->  Central Functions-> Supply Chain Planning Interface-> Core Interface Advanced Planner and Optimizer-> Settings-> APO Releases.

Adjust  the Advanced Planner and Optimizer R/3 Plugin

Check  the Advanced Planner and Optimizer R/3 Plugin within the OLTP system and import it if necessary.

See  the Plug-in documentation in the SAP Service Marketplace at the following address: http://service.sap.com/r3-plug-in.  However your Plugin should already be installed in the system after the  copy.

1.If logical        system names were converted in step 6.7 and the names of RFC destinations had been changed, you may also need to change RFC destinations that are maintained for specific applications in table CIFRFCDES.

In  SAP R/3, use transaction CFC7.

In  SCM, use transaction SM30 to maintain the view /SAPAPO/V_CIFRDS.

1.For an F&R SCM 5.0 system, follow the actions outlined in SAP note 862955.

1.Relevant only for homogeneous system copy via restore method and for SCM 5.1 or higher:

See  SAP note 1015489 to reset the APO system name in liveCache.

1.Run the ‘report for additional update after system copy’ as described in SAP note 1030857. This report will do the following adjustments:

When  you call transaction /n/SAPAPO/RRP and select a planning version, product number, and location, you see a link to the old system in the list of  product numbers.

The  external keys of account assignment objects (entries in the SSEXT field of  the /SAPAPO/ACCKEY table) still reference the old system.

6.12 – Install  and configure additional components

a.liveCache Starta.when using an external liveCache:i.Start the liveCache via Transaction LC10 in the target system (to do this, press the button “Start liveCache” in the liveCache          administration).

After that, both  the SCM database and the liveCache in the target system contain the same  data as the source system.

Notes:

SWPM will automatically start up the SAP system.

You need to stop this from happening.
