What is a context Row?
A context row is a row from a table like any other. The term ‘context row’ is used to refer to a row which is the context for a calculation expression. Being the context row for an expression means that where column names are used in the expression they are presumed to refer to columns of the context row. Each expression must be written with its context row type in mind. An expression intended to be evaluated in the context of a ‘House’ row will have access to different columns than one intended to be evaluated in the context of an ‘Invoice’ row.
