Hi Chris,
I am using PB classic and we configured the dw as xflso but it is not working. When you say mechanism is often quite poor or incomplete you mean that sometimes it will work and sometimes not? Because if that is the case SAP should identify the issue here to avoid confusion on the solution that we need to provide to the client. We insist to use GS as this is the only one that works for them but we need to defend it to management as they don't want to install not licensed/freeware in their environment coz it will violate security policy.
Regards,
Elena
