Debugging update rules and Transfer rules

Hai all,

I need to debug my update and transfer rules. Could somebody please tell me how I can do that and I would appreciate if somebody can refer me some kind of documentation on this too.

I know BW but very little about ABAP. I know a way- go to PSA>>right click on request>>simulate/cancel update>>select a line in details tab in Monitor and then simulate update.... But its a little too much technical and I am unable to understand it completely. Can somebody site me a little more detailed documentation or tell me a way to do it?

Thanks a lot.
