Hi Jon,

Thanks a lot for your answer. Unfortunately, with the mentioned query „SpecimenDetail" we get exactly the same error message:

> labkey.insertRows(baseUrl = baseUrl, folderPath = folderPath, schemaName = "study", queryName = "SpecimenDetail", toInsert = test_insert2)
Fehler in labkey.insertRows(baseUrl = baseUrl, folderPath = folderPath, :
  HTTP request was unsuccessful. Status code = 500, Error message = The query 'SpecimenDetail' in the schema 'study' is not updatable via the HTTP-based APIs.

Do you have some other possible hint?

Thanks and regards,
Eva
