Line_hierarchy

The syntax for Microsoft SQL Server is:

select * from line_hierarchy()
where top_mem in(
		select mem_id 
		from ctrain.line 
		where mem_name like '{Line}'
)

When {Line} is replaced by a selected member Sales from Line dimension, the result is:

mem_id mem_pid level top_mem
119 -1 1 119

Both the mem_id and top_mem columns contain 119 which is the member ID for Sales.
