Custom fields in table View

Hello Experts,

                     We wanted to add custom fields at task. We tried below activity,

1. Enhance DB table, added  the field in structure DPR_TS_TASK_EXTENDED_ATTR, object type TTO.

2. Define field groups for custom fields

3. Set up field control.

But fields were not visible we tried server restart for the same but it didn't help. So, We used configuration Show Additional Tab Pagesin Project Management under Project management Node in SPRO and used our Z webdynpro component to display those fields into respective tab. However, this fields are not visible in other views like graphics & table view . We searched here and found 2 notes 947936 and 972339 but this cannot be implemented in 6.0. How to achieve this ?

Thanks & Regards,

Alex
