The requested operation could not be performed because OLE DB provider "MSOLAP" for linked server does not support the required transaction interface.

I am getting the following error when attempting to INSERT the results of an "EXEC(@MDXQuery) at SSAS LinkedServer":

The requested operation could not be performed because OLE DB provider "MSOLAP" for linked server does not support the required transaction interface.

Here is code that illustrates what I am doing:

DECLARE @MDX varchar(max);

SET @MDX='
SELECT
{	
	[Measures].[Extended Service Count]
} ON COLUMNS,
NON EMPTY [Organization].[By Manufacturer].[Manufacturer]
ON ROWS
FROM (
	SELECT
		{[Organization].[Org Tree].&[2025],[Organization].[Org Tree].&[2040]} ON 0
	FROM [MyCube]
)
';

 
/* Test 1 */
EXECUTE(@MDX) at SSASLinkedServer;


/* Test 2 */
DECLARE @ResultsB TABLE (
	Manufacturer varchar(255)
,	ExtendedServiceCount float
); 



INSERT INTO @ResultsB (Manufacturer, ExtendedServiceCount) EXECUTE(@MDX) at SSASLinkedServer;

Test 1 succeeds, returning expected results, and Test 2 fails returning the error mentioned above.

Other articles I've found so far don't seem to apply to my case.  I am not creating any explicit transactions in my code.   When I use OPENQUERY, I am able to do the insert just fine, but not when I use EXEC @MDX at LinkedServer.

Unfortunately in some variations of the query, I run into the 8800 character limit on OPENQUERY, so I need to use this other approach.

Any ideas?
