Hello,

I did not see such error - however this looks like server error - can you repeat the error and then check the server logs?

(Open Administration Console and switch to Diagnosis Files section - review several most recent logs for relevant entries.)

Hello,

not sure if you were trying again but I;ve seen this in log:

Hello,

check definition of hierarchy - this might be related. Hierarchies are ignored except MDX connection that is used by Excel. This would explain why it works in HANA and fails in Excel.

Hello,

I was looking at your model and you have just Analytic View (just one column table in foundation and no Attribute Views).

Please try to define at least one dimension using Attribute View. MS Excel needs them for reporting (in your dimension you will see just key attributes - if you want to see also non-key attributes you need to set "hierarchy active" property to true).

Hi Tomas,

i had three different cube data foundations, with and without attribute views, and some of them have been deleted. the MDX error doesn't seem related to a particular configuration of the views. i don't remember having to set 'hierarchy active' in my initial tests before the refresh 8-9 days ago, but will keep that in mind in my next tests.

thank you for your excellent support so far.

Hello,

I was looking at your models ZGM01, ZGM03 and ZGM04. I can see that you were trying to add another table into Data Foundation but Logical View is always same.

In Data Foundation you can have one or more "fact" tables that are delivering measures. Then you need to define Attribute View and connect it to your Data Foundation in tab Logical View. This is not same as connecting source table that was used in Attribute View to the "fact" table in Data Foundation.

If you grant me privileges into your schema I can create new model illustrating this.
