can't set a fixed frame to use octomap mapping

i am using octomap mapping to create a map from lidar VLP-16 PointCloud2 messages, however every time my robot moves forward, i keep loosing the previous mapping. i think it's because i can't set a fixed frame in rviz, i can't find the fixed frame "map" to be working

How could i Be able to create the whole map using octomap mapping ?

Thanks for your help :).
