BW Extractors Problem - Source System Is Incorrect

[Former Member]

Hello,

I performed a homogeneous system copy of our BW system from our Production BW system to the Development BW system!

But now I´m with a problem regarding the extractors... when I go to transaction RSA1, I was trying to replicate data in a BWD extractor but it gives me an error. The problem is the Source Client that is not correct, it points to our ERP Production system (P70 client 100) but it should be points to the ERP Test/Quality system (T70).

When I try to perform a "Replicate Metada" it show me the following error:

Error during the retrieval of the logon data stored in secure storage

Can you help me please, how can I correct this situation?! How can I Change the Source System?

Thank you,

samid raif

HI Samid,

Please have a look at SAP Note 886102 - System Landscape Copy for SAP NetWeaver BW. I think that Scenario B3 is relevant in your situation. Apparently some of the actions are not executed, e.g. Step 6.7 (rename of logical system using t/code BDLS).

Also note that nowadays there is Post-Copy Automation (PCA). Please refer to 1707321 - BW System Copy: Post Copy Automation (BW-PCA).

Hi samid,

As suggested by Our Friends...take help from basis though it can be done by BW Consultant.

Basis Activity :-

However you can goto RSA1->Source Systems->Create Source System/Change.

We can Create and Connect systems as well.

Hi Samid,

Also the Sourcesytem would have got connected..probably you are checking in the Wrong place..

You can goto the RSA1->Modelling->Datasources->Check for the Corresponding Source System.

There may be two clients for the same source System...we can connect to both of them.

choose the one you want.

Hi Samid,

I would suggest take help from Basis Team.they will help you with source system mapping.

Hi Samid,

This is common issue when we copy from prod or quality logical mappins will be changed.

please take basis team help and change logical mappings at table RSLOGSYSMAP at bw/ecc side.

Your table need to have ecc dev technical name as source system rather than ecc prod technical name.

Once basis team maintain proper logical mappings, you can try to replicate and check it.

Inform to your basis to recheck the logical mappings details between ecc dev and bw dev.

Useful t codes - BDLS, WE20.

Thanks
