Destination R/3 System not mapped error

[Former Member]

Hi,

I am getting the error "Destination R/3 System not mapped". I am getting this error when tried to extract data from a data source in transaction RSA3. I resaved the data source (RSA6) and activated the extract structure (RSA2), but still getting the same error. Any help will be much appreciated.

When you execute the test of the DataSource in RSA3, are you specifying anything in the 'Target sys' field? Try selecting one of the Target Systems and executing the DataSource. If there are no Target Systems listed, then you don't have an RFC connection to a BW environment and you or your Basis team would need to set that up.

Hi Dennis,

Thanks for your response. No, I was not specifying a target system. Per your suggestion, I picked one of the systems from the list, and still got the same message. I was thinking in the same lines on an RFC may be missing, but I have this problem with only one of the data sources. I am able to extract data from other data sources w/o issues. I would think all the data sources will fail if an RFC is missing.

Also, this system is backcopied from another system recently. I am thinking some thing went wrong with this data source during the backcopy, but unable to pinpoint what that could be. Your help is much appreciated.

Thanks,

Ravi.

After further investigation, we found that the issue was related to a missing mapping entry in custom Z table. Issue resolved once we added an entry in the Ztable.
