BRF+: condition with SID is not considered

Hi,

In BRF+ when setting up the Team Determination, the condition should be added so that this should only be fulfilled in one system e.g. SOD.
The attribute 'SAP System ID' is used for this purpose. If this is set, the condition does not work. Without it, everything works fine.
Where does SID come from for the attribute? Is there any way to trace or debug it?

Regards,

Sergey
