We have an External Data column – "QVAS" which is linked to a table in a SQL server database ( the database is called QVAS)
We can update the item fine using SharePoint forms with the usual select or query options available.
The column stores the key to some property ownership data , and the related fields are important , e.g. QVAS:Owner and QVAS:LGA . See below
However, we need to use Nintex workflow to update this column. But we cannot workout how to do this using the Nintex workflow's "Updating Item" action in a workflow
Question How can we update SharePoint External Data Columns using Nintex Workflow?
Is it possible?
Is it possible using a Web Service Call, perhaps using REST , or SOAP?
We can use the Query BCS action to get values from the BCS, but cannot write them to the related list.
