want to add current stock in reports through CO26

Dear Experts,

I am generating reports through CO26 by using overall profile 000000000001 (STD profile). After executing I click on object option and check operation and components so that I get printout in desired format. Now I want to add field current stock in existing report . I tried fields option , but current stock is not available there . Is there any way to add current stock field ? or may be some other profile or some other t Code can give me desired output .
