Adaptions to project file

The following new views have been integrated in this release:

• tww_app.vw_tww_wastewater_node (in addition to tww_app.vw_wastewater_node)

• tww_od.tww_reach_point_labels

• tww_od.tww_wastewater_structure_labels

• tww_od.tww_wastewater_node_symbology

Please export and use the corresponding * .qml files to integrate them into your existing TWW 2025 project files

The following views have been adapted and need an adaption of existing TWW 2025 project files:

• Better configuration in vw_tww_catchment_area_totals (point-layer)

• Hint about necessary logcards in vw_catchment_area, tab fk_logcard

• Added info whether ws has log card to main view

• Added layer vw_tww_damage

• vw_tww_reach. labeldefinition for rp_from_label und rp_to_label renamed and with the replace-function so it will work with the variables for translation

• vw_tww_wastewater_structure: Symbology: replaced some ‘not “tww_is_primary” ‘ with ‘(not “tww_is_primary” or “tww_is_primary” is NULL)’

• vw_tww_wastewater_structure: Attributs Form: wn_elevation_accuracy also with option reuse last entered value (similar as co_position_accuracy)

• vw_tww_wastewater_structure: Attributs Form: _input_label, _output_label replaced with _reach_point_label

• New Project variable tww_language: values should be _en, _de or _fr

• vw_tww_reach labeldefinition: changed “material_abbr_en” to case when @tww_language = ‘_de’ then “material_abbr_de” when @tww_language = ‘_fr’ then “material_abbr_fr” else “material_abbr_en” end

• new layer tww_od.profile_geometry

• new relation pipe_profile.obj_id to profile_geometry.fk_pipeprofile

• profile_geometry Attribute form

• pipe_profile Attribute form (profile_geometry subtable only for profile_type special, mouth, open)

• vw_tww_additional_ws: field wn_fk_wastewater_structure no more in vw

• all identifier-fields: new enforced constraints length(“identifier” )<=nn or “identifier” is NULL (otherwise you loose all entries, if the identifier is to long)

• added a project-stored SQL “visualize profile_geometry”

• vw_tww_wastewater_structure: tww_is_primary, tww_has_log_card, _owner_organisation_type is not editable, owner_organisation_type configured as value relation

• vw_tww_additional_wws: reach_point_label, tww_is_primary, _channel_usage_current, _channel_function_hierarchic, _owner_organisation_type is not editable. _channel_usage_current, _channel_function_hierarchic, owner_organisation_type configured as value relation

• vw_wastewater_structure : tww_is_primary, _channel_usage_current, _channel_function_hierarchic, _owner_organisation_type is not editable. _channel_usage_current, _channel_function_hierarchic, owner_organisation_type configured as value relation

• vw_tww_reach: owner_organisation_type is not editable. owner_organisation_type configured as value relation
