material statistics group not showing text in report

Hi friends,

Initially i was having problem with # values for blank values in info provider,the issue is resolved by getting unassigned in place of #.Now the user wants description for all the material statistics group in the report.Like 1-do not use.2- do not use.I have activated the master data texts for the info object and also tried by using both key and text.How can i get the text values for the info object.??

Regards,

ali.
