Reconstruction

I can see the Request 121235 in InfoCube ->Manage ->Requests tab.

I also can see this Request in InfoCube ->Manage ->Reconstruction tab.

I deleted the Request in InfoCube ->Manage ->Requests tab. Then in InfoCube ->Manage ->Reconstruction tab, I selected this Request and click on Reconstruct button.

But this is not happening, InfoCube ->Manage ->Reconstruction tab, the Request available in data target column is RED. It says the Request is no longer exist in the data target.

What I expect is system will restore back this Request into InfoCube ->Manage ->Requests tab. Is this what the Reconstruction is doing?

OR

I should not delete the Request in the Request tab?
