Post processing steps for SAP BW system copy or db copy
.
After system copy, you nees to perform some post action to reactivate the extractors
Usually, to have the data sorted, you refresh both the source and target system.
If you run the refresh only the BW system, you can ignore the first paragraph
Action in souce system
- BDLS
Converts occurrences of the value for logical system name in various tables.
Convert BAPCLNT100 in BATCLNT100
Convert <LOGICALNAMESOURCE_PROD>in <LOGICALNAMESOURCE_TEST>
Do not continue until both the logical names have not been converted
- scc4
check if in Logical system name is correct ( BDLS should fix it )
- sm59
check that it exists and functions, the RFC connection BATCLNT100
- we21
check that there is a door that points to BATCLNT100 (ex change the port A0000000XX that points to the system of production BW)
- sale
create new logical system BATCLNT100 (note the system must be open to change in order to change the table)
- we20
create new logical system BATCLNT100 like LS type, you must reset all flags of BAPCLNT100. So the most ‘safe is to create it as a copy of BAPCLNT100 (the “No Partner” is the logical system, not the RFC connection!). After that in Outbound parmtrs, click twice on the message t ype, the screen will open with the parameters configured, check that the door is the same as previously configured in WE21.
Check that in Classification , patner status is active ( A – active , I – inactive).

Check the entry in follow table; should relate to the test

Some of the step are only a check if the transaction BDLS are finish in both systems for both logical names.
If BDLS is not finished , you can obtain a DUMP.

Hi Antonietta,
i have a doubt about the function: RSAP_BIW_DISCONNECT. Why do you insert this step under "Action in BW system"? Because in note 1478123 - point 4 - we read: Never execute this function module in a BW system!
Thank you for this explanation.
Cristian
Hello Cristian,
the note 1478123 regarding "Source system issues."
The point number 4 is How to disconnect all obsolete links to BW.
If you run the function module in a production environment, you will lose data because you're disconnecting the chains.
But I carry a double copy: both systems Bw and R3.
I have to unplug the BW test from ERP production and return it to the ERP test.
In my case I do not want to interrupt a dead link, but I have to reconnect the data inì configuration BW TEST <-->TEST ERP.
You can not simply add new connections, but you must first delete obsolete, because otherwise you will have problems with the field RSBASIDOC of the table TSPREFIX .
when you will activate the routes from the transaction RSA1.
I hope to you useful,
best regards,
Antonietta
Great guide, very useful! You forgot to translate this part:
modificare il nome logico
😯 OPSSS
Thanks Daniel
Hi,
Please be aware that there is now an automated solution for that procedure.
See - http://scn.sap.com/docs/DOC-7856#section14
