SAP R/3 Integration + StoreOnce + Source Side Deduplication - [No source side deduplication device]

Hi,

I have a problem with the configuration of the DP integration of SAP R/3 and our test StoreOnce.

At first, our normal backups via brbackup to the HP D2D is still working, I got a test system due to perfomance issues with the D2D.

I've created a store in the StoreOnce (Store_1) and set up the new device in Data Protector.

Added the gateways for the SAP system for source side dedup and tested it via a simple filesystem backup and restore.

That's working without any errors.

After that I created a new SAP Backup (test) for the SAP system and chose Store_1 as destination.

To verify the settings, I started a preview of the backup, which ended with success:

I also see on the StoreOnce the blank media with a size of 5.6 MB .

On client side I edit the SAP util_file:

Old:
OB2BARLIST=SID
OB2_3RD_PARTY_BACKINT=1
OB2BARHOSTNAME=SID
New.
OB2BARLIST=test
OB2_3RD_PARTY_BACKINT=1
OB2BARHOSTNAME=SID

If I start a test backup (online without redo logs), I get the error: 

No source side deduplication device that matches object BAR SID:SID.0 "SID" could be instantiated.

I think that's a problem with the OB2 parameters, or? I also tested OB2BARLIST with various parameters like:

OB2BARLIST=test
OB2BARLIST=Store_1              [Device Name]
OB2BARLIST=Store_1_Source_side  [Drive name]

I don't find anything about this in the Integration Guide for Oracle and SAP or in the D2D Guide.

Does someone else is using SAP and StoreOnce with Source Side DeDup?

Data Protector: 7.00

Thanks for any advise!
