[Former Member]

Dear Experts,

We are having 3 system landscape in our organization. We having both ECC & CRM system. Below are the charts.

	ECC	CRM
Dev	ECD	CRD
QAS	ECQ	CRQ
PRD	ECP	CRP

CRM QAS to ECC QAS Middle ware connectivity configured and CRM Production to ECC Production Middleware configuration is there.

Our DB platform is Oracle. Now we will do the QAS system refresh (both CRM and ECC). We will use backup/Restore method the below link:

Now my question is as all the Data and config at QAS will be refreshed by production... what are the Data for example RFC, we need to keep backup specially to continue the QAS system Middlware and other functionality? Please help me to avoid any problem? and how to take these backup?

Regards,

5. Take the screenshot of we20 , we21

6. Take the export of distribution model using the transaction BD64

7. Take the backup of the kernel directory and profile directory.

6. If you have configured SSL in your system , then you have to take the export of the below tables and also need to backup the sec folder.

In Post activity:

- You have to replace the profile with the backup profile and make the parameter for rdisp/wp_no_btc=0

- Suspend all the jobs in the target system

- Import the RFC

- Run the BDLS for all the logical system which are connected to ECC and CRM

This are the main activity in system refresh.Kindly let us know , if you want some more information.

Hi Asaduzzaman,

Please refer to below 2 notes related to SAP CRM copy:

564435 - Additional information on CRM System copy

886104 - System Landscape Copy for SAP CRM

Procedure to take backup of all RFC connections through Transport Of Copies.

1.       Create Transport of Copies request through SE10 transaction and make sure that target system has given while creating transport request.

2.       After creating request just double click on request and go to Objects tab and give all RFC Tables (RFCDES,RFCATTRIB,RFCDOC,RFCSYSACL,RFCTA,RFCDESSECU,RFCGO,RFCCHECK,RFCTRUST,RFCTYPE) as below and save it.

3.       Double click on each object name and give * for Table Keys.

4.       Release Request by clicking on Truck button (before releasing again make sure that target system has given)

5.       Check cofile and datafile at OS level to make sure that transport request released successfully.

Below are the tables you need to export.

TSP03 - Printers

USR, AGR -> export usermasters and profiles

RFCDES - RFC destinations

V_TBDLS  - Partner profiles

Note - For user master you can just take an export using SCC7.
