Hi Jon,

Thanks a lot for bringing us to the right solution; the repository was not set to „Editable“ - after changing that the R-api works now (see below):

> labkey.insertRows(baseUrl = baseUrl, folderPath = folderPath, schemaName = "study", queryName = "LocationSpecimenList", toInsert = test_insert)

$rowsAffected
[1] 1

$queryName
[1] "LocationSpecimenList"

$schemaName
[1] "study"

$containerPath
[1] "/Steinmann3"

$rows
list()

$command
[1] „insert"


Thanks once more for your great support!
Eva
