Lookup Lists
The Lookup Lists feature enables predefined value–description pairs to appear in a dropdown for selected cells in the EDM spreadsheet or property forms during editing. You can either select a value from the dropdown or enter a custom value when needed.
Lookup list dropdowns are provided for all editable properties. You can quickly locate
the correct option by searching through either the value or the description.
Note: Lookup lists become available in EDM after you provision
iModels with properties that include the VALUE_DESCRIPTION_ATTRIBUTE, using the
OpenPlant_PID_Supplemental_Design.01.08.ecschema.xml schema.
For the lookup list to appear in EDM, make sure you have updated the OpenPlant extension schema: OpenPlantExtensions.ecschema.xml. Until this schema is updated, the picklist will not appear during the provision or upgrade workflow.
Guideline for Enabling Lookup List in EDM:
- Make sure you are using the latest OPPA build (e.g., 24.00.03.20).
- Replace the updated OpenPlant extension schema
(
OpenPlantExtensions.ecschema.xml) at the workspace level. - The lookup/pick list will not appear after provision or upgrade until this schema is replaced.
To get the updated schema, you can copy the latest schema from one of these locations:
-
C:\ProgramData\Bentley\OPPA 2024\BIS\OpenPlantExtensions.ecschema.xml C:\ProgramData\Bentley\OpenPlant 2024\Configuration\WorkSpaces\OpenPlantExample\Standards\OpenPlant\Schemas\BIS\OpenPlantExtensions.ecschema.xml
To update it in the WorkSpace, replace the existing file at your workspace path, for
example:
C:\ProgramData\Bentley\OpenPlant 2024\Configuration\WorkSpaces\OpenPlantExample\Standards\OpenPlant\Schemas\BIS\OpenPlantExtensions.ecschema.xml
Note: After you update the schema, re‑run the provision or
upgrade workflow. The lookup list will then appear as expected.
