How to do client copy in SAP BW after database content refresh

We created a homogenous system copy by backup/restore from our Production BW (Netweaver 7.5) to Quality BW (Netweaver 7.5). At the same time we also did a system copy from our ERP Production to the ERP Quality. The productive clients in BW PRD and BW QUA differ (300 in PRD and 100 in QUA). After the system copy we wanted to keep the QUA system as close to the system before copy and wanted to create a client copy from QUA.300 to QUA.100 but it seems like this process is not supported if we want to retain all the data in the post-copy QUA system.

We followed the scenario B2 in note 886102 (https://me.sap.com/notes/886102) but even when we go through all the steps in the target system and running BDLSS we still get the error "Logical System name has been changed for this system". Is there something important not mentioned in the note that has to be done in addition? Should we delete some configuration before changing the logical system for the target system client?

Best Regards,

Rauno

The error message means that you already changed (on t-code SCC4 perhaps) the LOGICAL SYSTEM name before running the BDLS. This is not allowed. The change should be done only through the BDLS t-code, no matter if it is a ERP or a BW.

Because you did also a system copy of the ERP, the more appropriate scenario is the A2, because you copied the BW and the source system (ERP).

Yes sorry, that was an unintentional typo. I meant A2.

It's good that you mentioned the order. Indeed I set the logical system for the client before running BDLS. Trying it the other way around and will update with the results.

Everything runs fine in target system once I do the regular BDLS without touching any of the logical systems manually. However, if we continue in the target system with creating a new client QUA.010 and doing a client copy and running the same BDLS process again, the new client cannot be used for RSA1 anymore. Is that a limitation on BW?
