Run scriptPOSENTUP.sql.
“…before starting the registration process the following script needs to be run.
$APPL_TOP/pos/11.5.0/patch/115/sql/POSENTUP.sql
This script establishes the Enterprise Name that will be used in all of the notification emails used during the invitation and registration processes.
The script prompts for an enterprise name as an input and updates the relevant tables with this information.
If this is not set, the invitations which go out for suppliers for registration will not have any Name.
So, it is recommended that this script be run before sending out any invitations or completing any registrations.”
Script is valid as well for release 12 and higher.
