Error code 7321 when running MDX query using openquery

Question

Hi I have written the following MDX query which fetches data from a cube which is on a linked server,

I am new to MDX queries and hence i am not able to find out what the error means. Please let me know how to solve the following error.

Answer 1

Looks like a timeout to me. Can you increase the query timeout for linked servers (and openquery) mentioned here? https://support.microsoft.com/en-us/kb/314530

configure 'remote query timeout', 0
go
reconfigure with override
go

Answer 2

This is an alternative rather than a direct answer to your question.

Instead of using OPENQUERY try the following CLR solution: https://olapextensions.codeplex.com/

We used to have lots of OPENQUERY based mdx and have started to move it all onto this CLR stored procedure. Advantages are:

• No linked servers are needed
• No problems with string lengths
• Much much easier data type conversions.
