Hello,   This error always appear when I'm trying to perform a write stage with a string starting at "@" (example @Hey) on any SAP fields using SAP mode (Scripting). Would anyone know why?  The string was not recognized as a valid DateTime. There is a unknown word starting at index 0.

Try using global sendkeys instead for that scenario.  There is a send keys guide in the documents area of the portal.
