... I am not able to find all these empty fields dataowner / dataprovider. They are in tables that are not in the project. The message does not help -> I will make a suggestion for this problem

[domi4484]

To get a valid XTF dataowner / dataprovider must be set to a valid organisation. I agree that the error message is not very helpful

[urskaufmann]

I deleted the records of the layers in QGIS (exception: organisation and pipe_profile). Then imported the test-dataset-dss again with the import-function.

Then exported again dss, without labels and got this error below. The problem of this errormessage is: Key = 489 is not an obj_id, it's a transfer-id. The user can not find the record with the error. And of course: if I have imported successfully and make no changes, it should be possible to export without error. Something is not ok.

[urskaufmann]

If I select with netfollowing all reaches above manhole 1.001 and export just the selection, the DSS export works.

[domi4484]

And of course: if I have imported successfully and make no changes, it should be possible to export without error. Something is not ok.

Yes, but you wrote that you don't deleted pipe_profile. Maybe is there some more invalid data still in the DB?

If you try with a clean database you get the same error?

[domi4484]

@urskaufmann I can reproduce as well now. Will check it out

[domi4484]

@urskaufmann I attached a new version of the plugin here, should fix this issues

[urskaufmann]

I get now this error: Could not create the ili2pg schema: Open the logs for more details on the error.

and in the logfile: Error: SIA405_ABWASSER_2020_1_LV95: model not found

tried also with export to DSS -> same error (model not found)

update 19.1.2024 9:25: model was found now.

[urskaufmann]

By the way: when installing this new plugin, I got this error (but installation was then successful)

I had this also – could be because the zip is created on a Mac and contains beside a teksi_wastwater folder also a _MACOSX Folder

@urskaufmann I uploaded the newest plugin on the discussion main post. Can you try if you can install the plugin and the export of SIA405 and DSS work?

[urskaufmann]

Installation of new plugin: OK, no errors Export DSS of a selection with no missing attributes: works, no errors.

I export then with the same selection, DSS with labels. I get error and no export-file:

I export then DSS without selection, without labels (there are missing attributs). I get a better message:

should be fixed in last plugin demo, please re-open if needed
