The GROMA system allows working with several tables within one database. This can be used e.g. when creating geometric plans, when the points you want to display in the graphic can be saved in one table when drawing the plan, and in another table the points which shall be listed on the coordinate list on the geometry plan can be saved. Using this command, you can choose the active table above which all the database actions are performed (points export and import). You can find the details on the technology of the creation of a geometric plan and on tables in the graphic module manual.
