Problem when adding SRM Report "transaction code" link to NWBC ***urgent***

Hi friends,

I have a problem in srm 7.02

I maintained the supplier user's roles, and the overview of procurement tools are shown as below.

The problem is, when I try to add transaction code/s with user role, unfortunately I cant see the report tab or report codes n NWBC.

The report code is just shown as below,

Where should I check for this and what should be the solution for this problem?? (WebDynpro app, Trx. Code Maintenance etc.??)

Thanks in advance
