Hi, Samual! 

Would you please send a piece of your MDX which has a bad performance.

Alessandro's example is very general.  In many cases you can reach the same result without PERIODSTODATE and PARALLELPERIOD functions and any %OR statements.  E.g. to make the Year-to-Year(YTY) monthly comparison you can just use the following (Holefoods Sample Cube):

SELECT [Measures].[Amount Sold] ON 0,NON EMPTY {[DateOfSale].[Actual].[MonthSold].&[201612],[DateOfSale].[Actual].[MonthSold].&[201512]} ON 1 FROM [HOLEFOODS]

Which shouldn't cause any performance issues for any number of rows.

If you want to parametrize the month with pivot variable the expression for YTY for any month could look like the following (assuming the $variable.month is a list of months):

SELECT [Measures].[Amount Sold] ON 0,NON EMPTY {[DateOfSale].[Actual].[MonthSold].&[$variable.month],PARALLELPERIOD([DateOfSale].[Actual].[YearSold],1,
[DateOfSale].[Actual].[MonthSold].&[$variable.month])} ON 1 FROM [HOLEFOODS]

HTH

It turns out that it is yet another setting! (Oh, Drupal...).

So, there is Subscription->Overview->Settings->Visibility of Controls section which controls the visibility of Update and Comment settings in "Content types" tab. Don't ask me whoever needs this setting, so if you make it Visible you can find this settings in "Content types" for Posts and Answers.

We plan to turn on this Visibility of Controls thing for all the members with the next DC release.

Hi, John!

I see you have digest mode turned on. Please turn it off to get reasonable notifications.

Regarding your question - I bring my apologies. This checkbox will influence only the new future subscriptions (as it documented in this settings section).

So if you were subscribed to the post you have this setting already and it cannot be unchecked or unsubscribe and subscribe again.

Maybe it's not a bad idea to turn off this "notifications on updates" setting for all the current subscriptions for all the users.

Hi, Scott!

You got this message because somebody changed the post.

Two things about that:

First turn off please the Digest mode - it doesn't work properly and sends senseless messages :/

Second: turn off the Update trigger for notifications. The checkboxes should be off as on the screenshot:

 

 

 

After that you'll get reasonable notifications and only for the reasonable causes.
