MDX Query with Crossjoin and Filter Times Out - filter

Question

I keep timing out every time I try to run this query. It seems to work until I add in the "([Finished Product].[Primary].MEMBERS," section into the rows section of the query. Any ideas?
SELECT NON EMPTY {[Measures].[Retailer Event Margin Pcnt (Actual, WB Total, LE)], [Measures].[Incr Cnsmp Units (Actual)]} ON COLUMNS,
NON EMPTY {[Finished Product].[Primary].MEMBERS * [Promotion Plan].[Promotion Plan].[Event].MEMBERS}
HAVING LEFT([Promotion Plan].[Promotion Plan].CurrentMember.Name, 6) = "Anchor" ON ROWS
FROM [PEA]
WHERE ( [Time].[Fiscal].[Fiscal Year].&[2017] )

Answer 1

Try the "nonempty" key word , which evaluated the set on axis level, "non empty" is evaluated on top of the query which may have a performance issue for a large set.
nonempty(
nonempty([finished product].[primary].members,[your measure])*[promotion plan].[promotion plan].members,[your measure])
It just a reference, and you need do some changs on it for your case.
hope it helps.

Try filtering before the Crossjoin:
SELECT NON EMPTY {[Measures].[Retailer Event Margin Pcnt (Actual, WB Total, LE)], [Measures].[Incr Cnsmp Units (Actual)]} ON COLUMNS,
NON EMPTY [Finished Product].[Primary].MEMBERS
* Filter([Promotion Plan].[Promotion Plan].[Event].MEMBERS, LEFT([Promotion Plan].[Promotion Plan].CurrentMember.Name, 6) = "Anchor")
ON ROWS FROM [PEA]
WHERE ( [Time].[Fiscal].[Fiscal Year].&[2017] )
