Adding a debugging col/row in MDX

Question

Is it possible to add a manual column to make debugging MDX query results easier? For example, something like:

SELECT {
     DESCENDANTS(...),
     " --- end of descendants ---",
     ASCENDANTS(...)
} ON ROWS

Answer 1

Yes you can, calulated members are the way. Take a look at the sample below where i have printed the current member, last member and next member

with member measures.CurrentName
as 
[Product].[Product Line].currentmember.name

member measures.NextName
as 
[Product].[Product Line].currentmember.nextmember.name

member measures.LastName
as 
[Product].[Product Line].currentmember.prevmember.name
select {[Measures].[Internet Order Count],measures.CurrentName,measures.NextName,measures.LastName }
on 0,
[Product].[Product Line].[Product Line] on 1

Based on the comment below about adding a row

Here is a sample that adds row too.

with member measures.CurrentName
as 
[Product].[Product Line].currentmember.name

member measures.NextName
as 
[Product].[Product Line].currentmember.nextmember.name

member [Product].[Product Line].[CustomValue]
as 
"End of descendants"
member measures.LastName
as 
[Product].[Product Line].currentmember.prevmember.name

select {[Measures].[Internet Order Count],measures.CurrentName,measures.NextName,measures.LastName }
on 0,
{[Product].[Product Line].[Product Line],[Product].[Product Line].[CustomValue]} on 1
