MDX can be used in:

Dimension Subsets
Cube Views in PAW, PAX
In TI processes to create source views, build subsets.
In PAX or Perspectives dynamic reports, and probably Universal reports but not got around to those yet.

Just to be clear, re the last question, is that scenario theoretically possible and if so is there nothing that can be done? Asking for a friend....

- In PAFE, report definition for: Quick Report, Exploration, Universal Report, as well as parameter for functions e.g. TM1SET

- In PAW, report definition for explorations and all other visualizations

- In TM1 Server definition for subsets/sets and views, as well as input for various Turbo Integrator functions impacting subsets/sets and views

Correct answer:

MDX can be used in:
  1. Dynamic subsets
  2. MDX views
  3. TM1SET function
  4. Tm1ellist function (nobody has mentioned it, but it's a very powerful function, check it if you are not using it. For example, here I have described how to make dependent picklist using TM1ELLIST: https://advoynev.wordpress.com/2021/10/ ... -function/)
  5. CreateFromMDX, ReplaceWithFormats and other functions in PAX-API
Winner of this week is Adam for the most detailed answer (including the great new TM1SET function)

Question #15:
What will happen after you type "10>" in a cell?

Nothing. You have to hit enter first. :-)

After you hit enter, 10 will replace each of the cells in that cell and to the right. In this case Total Year will now equals 120.

Does this exclude the 1 dimension cube that TM1Fanboy hacked once? :lol:

Two. However, I remember getting weird issues with some client apps, so I always do at least three.

Dimension attributes or element attributes? Attributes for elements of the primary hierarchy of a dimension are stored in a separate, two-dimension cube with name like "}ElementAttributes_<DimensionName>". The two dimensions are the dimension itself and a measures dim called "}ElementAttributes_<DimensionName>". Attributes for consolidated elements of alternate hierarchies are presumably also stored in a similar cubestore, but that's not viewable as a control object in PAW/Pafe or Architect. Dimension level attributes are stored in a cube called "}DimensionAttributes".

Correct answer: In "}ElementAttributes_<DimensionName>" cube (Yes, I've meant element's attributes, thanks)

Winner of this week is ascheevel and he takes the lead!

Question #18:

Write a feeder for this rule. Note that Volumes are more frequently zeroes than Prices:

Code: Select all

[‘Sales’] = N: [‘Volume’] * [‘Price’];

Hi,

The feeder would be:

Code: Select all

[‘Volume’] => [‘Sales’];
How did ascheevel overtake Admin in the lead, given he was in the lead the previous week? :?

Leaderboard with points is on the 1st post, you can check there.
There were some errors there (too many of you are starting at "A"! This confused me a bit :) ), this is now fixed

Question #19:

Ok, that was simple. How about that?

Write a feeder for this rule:

Code: Select all

[‘a’] = [‘b’] + 4;

Code: Select all

[‘a’] = [‘b’] + 4;
For this one, ['a'] will need to be fed when ['b'] is not -4.
You can't feed from ['b'] because if it's 0, there's no feeding, therefore ['a'] will be an unfed 4.

Assuming the model already has a "Config" cube, I would add an element called "Feed Static Addends", set its value to 1 then add the following feeder:

Code: Select all

['Feed Static Addends'] => DB(... 'A');
That would be my approach. It's possible to tighten up the scope of the feeder using a conditional feeder checking whether ['b'] <> -4, however people smarter than me debate if conditional feeders are a best practice or a worst practice.

Hi,
Assuming the model already has a "Config" cube, I would add an element called "Feed Static Addends", set its value to 1 then add the following feeder
Then why not set the value to 4 and do a DB to the config cube in the rule, rather than hard code 4.

I would assume this must be a small cube or 4 is going to get populated in very many cells, I wonder if we have enough information to be able to fully answer this question. But based on the information we have why indeed not remove Skipcheck!
It's possible to tighten up the scope of the feeder using a conditional feeder checking whether ['b'] <> -4, however people smarter than me debate if conditional feeders are a best practice or a worst practice.
Smarter people than me will have to tell me how conditional feeders can possibly be avoided for any 'real life' model, so I cannot accept its bad practice, I see it as an option at our disposal.

Anybody else? I think it's one of the hardest questions in this quiz

@MVPs, @Admins, can you share your thoughts also?
