Process chain - Two source system issue

Hi Experts,

I face problem when i transport a process chain from BW DEV to Quality.

I have two source systems in Quality ECI and EXS.EXS is a sandbox server(Source system) which we no longer use.

When i transport the process chain from DEV to QA, i get two DTP's automatically added to Process chain in quality for two source systems ECI and EXS whereas i do not want the data to be loaded from EXS client.

I checked the BW dev system, it has only one DTP in the process chain.

Now I want to elminate the other DTP in the process chain in quality.

Please suggest.

Regards,

Srini
