I have no idea what tool you are using, but if auto correlation does not work, leverage your training and manually correlate.
And, in general. We are all volunteers here. Asking twice will often have the exact opposite of the effect intended. If your situation is that critical you may want to turn to your internal mentor or contact your tool vendor's support organization. The tool vendor's organization will expect you to have the common basis in the tool as provided by training
It would be good to contact these folks and let them know you are having difficulty. Did you receive training or can they arrange training for you? You didn't mention the tool you are using. Let us know and someone may have some specific ideas for training.
