When using the :EXPORT function in a distributed, active/active, or multi-server environment with multiple servers having an Automation Engine, the server cannot be specified and a UNC path or mounted driver must be used that is accessible from all nodes. Is there a way to specify a server?
This behavior is considered as designed. There is no way currently to specify a specific node on which to export a file.
If specifying a node on which to export a file is something you're interested in, please contact Support with regards to a Request for Enhancement (RFE) so that Broadcom can gauge interest in this feature and assess whether it should be added to the product
