Most objects have defined standard fields (masks).

 

Example:

WareHouse?$mask=1

 

This creates the following command:

WareHouse?$select=WhsCode,WhsType,WhsColor,WhsBitmap

 

Beas uses this query option for drop-down lists. This way all drop-down lists always have the same format.

Combinations with other commands are possible, except $select.
