The two lines of logo news can be edited from internal application TPXMAIL in Option "16 - Update Logo news". When a user starts TPXMAIL he sees the "TPX Message Menu" panel and a total of 16 options. If Option 16 is not shown in bright white color the user has no right to access that Option.
To allow him update of the Logo news, first check which Command Authority table is selected for that user. Go to TPXADMIN, select "1 - TPX User/Group Maintenance", then "3 - User Maintenance" and enter the userid in question. Select "1 - TPX User Options" and you see the users Group Name and the Command Class.
Now go to TPXADMIN, select "1 - TPX User/Group Maintenance", then "Command Authorization Class (CMDT)". Then select the Group the user belongs to and finally the Command Authorization Class.In panel "TPX Command Authorization Class Detail Panel" hit PF8 and in the lower left you can change the value of Option "Update logo news from Mail" from 'N' to 'Y'.Finally reload that Command Class using TPXOPER Command RELOAD CMDT=<name_of_class_table>After the user logged off/on he is able to edit the Logo News.
