Defects for Urgent Changes

Hi,

As per SAP standard Normal Change, we create Defect Correction during test phase. As Defects are for Project & not for particular change.

But is it possible to create Defect for Urgent Changes & how can we link defects for Urgent Changes.

Also I am looking at creating Incident to fix Defect in Urgent Change.

Any pointers..

Regards

P Kumar
