Thanks for the feedback.
There is an excel list which is populated by different users.
The details in excel list then need to transfer automatically in a sharepoint list.
If there is completely new data, then the whole row is re-added in Sharepoint List.
If the data already exists in Sharepoint List?
then the data will only be updated
To determine this, then the serial number of a row in Sharepoint List must be compared with the serial number of an Excel list.
But this does not work and I get an error, so that column "Serial number" is not present in Sharepoint list, although the column does exist.
I would like to compare "Seriennummer" in Sharepoint list with "Seriennummer" in Excel.
