Extend 'Display Customer List' (F2640) Fiori tile to add another standard field from KNB1 table

Hello,

We need to extend 'Display Customer List' fiori tile to add another standard field KNB1-XAUSZ in the tile output.

I tried to add it through 'Data Source Extension' under 'Custom Fields and Logic' but Customer List data source not available for extension.

Please help to extend the tile to add this standard field.

Thanks,

Deva
