Regarding RSRT transaction Code

HI BW Gurur's,

I had created a customer Exit type variable. and written all the abap code. Inorder to debug the abap code, I used RSRT transaction code. When I selected the execute+debug option after giving the query name, it is displaying the following Message in the status bar....

"Query could not be opened! GENUNIID is invalid"

Is there any other alternative for debuggin the abap code???

Appretiate if any one let me know how to use RSRT transaction code as I am new to RSRT.

Thanks in Advacne,

Dilse...
