Debugging of SAP Standard webdynpro component

Hello Everyone,

I got a query such that using Change request, material and create by. i need to display material, CR details. CR and create by was created.. problem with material arises, i couldn't able to retrieve the all CR data associated with material, it shows only Last Cr attached to material, so i was trying to check the Standard SAP webdynpro Component, Anywhere it doesn't have a Debug option. If you have any idea on this please reply ASAP.

Thanks in Advance.
