Aggregate on Hierarchy

Hi,
I was creating an aggregate on Hierarchy of Characteristic 0Plant.
and while creating i got a screen "Select variable or Fixed date" having 4-5 colums
where it has like this ID | Objectname | Long description | Changed by |
coloms has values like under long description
1. Two months prior value to year
2. Prior year key date
3. Current calender year (sap Exit)
At the bottom it has options "Transfer selections"
i wonder what this is.
Any help on this is highly appreciated !!
Thanks in advance
Kiran

Hierarchy restrictons not working with Basis servicepack upgrade to 14

Hi All,
We recently upgraded our system with basis sp 14, and we having the below problems with out hierarchy restrictions:
Problem #1
We recently upgraded our system from then onwards hierarchy restrictions not working, users are getting authorization error when they execute the query. However we tried by adding aggregates now hierarchy restrictions seems to be working.
Problem #2
We are testing hierarchy restrictions for budget planning function, after we add aggregate its allowing the user to plan the data, but when they try to distribute or escalate the data its again throwing authorization error. When I checked error log for Orgunit hierarchy restriction, the query is looking for single values it is not considering the node restriction, the orgunit values appeared in error log all belong to the node I restricted in analysis authorization.
We implemented note#1133674 as this was relevant to our issue with planning function. But this didnt fix the issue.
We are now on BI SP 16 and Basis SP 14
Just wondering If any of you came across with the same kind of issue, Any help is appreciated.
Thanks,
Kavitha

Hi Kavitha,
Please check SAP note 1229602 Error when using hierarchies: Authorization error.

BEx Analyzer: How to optimize reporting over a hierarchy?

Hello there,
using BEx Analyzer & Excel, we're reporting over a large hierarchy of cost centers, beginning at the top level and then looping over 166 different cost centers in that hierarchy.
Looping works from within a macro, calling the SAPBEXSetFilterValue for the corresponding query.
Reporting takes about 5 hours at the moment. Is there any way to speed up the calculation after setting the cost center as a filter value? Example: we need to report the top level node anyway, so the query needs to calculate over all hierarchy nodes. What happens to the results of the lower level nodes? Are they just dropped and calculated again later when the cost center of that lower level node is set as filter value? It would be a good thing if BW could cache these results so that it just needs to download them when needed later instead of calculating again.
Any idea? I don't now very much of BW concerning that point, so any hint is very welcome. Our release is BW 3.1.
We already tried RSRT but all we could do is to set the behaviour in case of query navigation. I'm not quite sure if this covers the case we want (setting the new filter value). At least, execution of that report still takes about 5 hours.
Thank you very much.

Andreas,
Create Aggregates on Hierarchy level.
Use Read mode H.
Make use of OLAP CACHE.
Have a look at RSRCACHE.

How to find "good" aggregate candidates?

Hi specialists,
I'd like to know how one can find good aggregate-candidates - without hopping from bw-user to bw-user and ansking him "which characteristics do you use mainly"?
I know that the rsrt gives the possibility to show the aggregate that would have been used if it would have exist.
The hatch: Aggregates are on a "per cube" base - not really on a per query-base.
It would be nice if the BI-Statistics could provide information about the mainly used characteristics-combinations per Cube. But I did not find such an information yet.
So my question is: How to you determine good aggregate-candidates - without "guessing" and "user-hopping"?

Hi Marco,
first question would be: What is a good aggregate ?
Usually this is a aggregate which is often used and which will really speed up queries.
I only try to find aggregates if users start to complain, because maintaining them can be verytime consuming. So first rule: Create no aggregate unless you have no other choice.
If users complain, I go to the RSDDSTAT tables. Unfortunatly you did not mention if you use 3.5 or 7.0. Both use different RSDDSTAT tables. But they have one thing in common: They deliver Information about DB performance, number of read entries and number of used entries. An aggregate will only help you if the performance problem is in the DB time. Everything else is cache, release, client.
Okay, assuming you found a lot of queries which a long DB time. Then you can look at the number of read entries. If the read entries and the used entries are on the same level, no Aggregate will help you. If there are significantly more read entries than used entries, an aggregate may help (example: 100.000 read, 20.000 used is worth considering an aggregate). If you found queries with characteristic, you have to take a look at them and find out which causes the large number of reads. Then hopefully you will find out which aggregate would be usefull using RSRT.
There is categorie of Aggregates which come in handy: Aggregates on Hierarchy levels. If some of your Queries use hierarchies, it may be usefull to create aggregates on a middle hierarchy tier. Especially if the users tend to start at the hierarchie node an drill down.
That are some thought to consider. Hope it helps.
For more, I would like to suggest the most interesting SAP Training I ever did: TEWA50 BW Query Tuning. This training is always mentioned in the Early Watch Alert, but I couldn't find any entry in the SAP Training schedule since BI 7.0.
Kind regards,
Jürgen

What is the diff b/w logical query and physical query?

Thanks In advance

In OBIEE terms the logical query is how you query the BI Server, the Presentation services sends logical SQL to the BI Server, you can also write your own using JDBC , pull from BI Server using ODI etc.
The BI Server engine takes this logical query and writes (a number of) phyiscal querie(s) to satisfy the logical request, depeninding on how your BMM and Physical layer is setup. There are a number of rules the BI Server evaluates before deciding the most appropriate Physical query to generate, rules include Physical Joins, Aggregate tales / Hierarchy levels and so on.
Hope this helps,
Good luck with interview :-)

Query Performance Issue based on the same Multiprovider

Hi All,
I am facing a performance issue with one of the BEx Query 1 based on a particular Multiprovider.
I have done all the kind of testing and came o a conclusion that the OLAP: Data Transfer time for the query is the max at around 820 Secs.
The surprising part is another Query 2 based on the same multiprovider runs absolutely fine without any hassles with OLAP : Data Transfer time with merely 3 Sec.
Another, surprise is that Query 2 has even more Restricted Key Figures and Calculated Key Figures but it runs smoothly.
Both the queries use cache memory.
Please suggest a solution to this.
Thanks.

Hi Rupesh,
There is no much difference between the 2 queries.
Query 1 - which has performance issue has the same filters as that of Query 2 - which is working fine.
The only difference is that the selection of Fiscal Week is in the Default Values Pane for Query 2 whereas its in Characteristics Restrictions in Query 1. I doubt whether this setting will have any effect on the performance.
Both restriction i.e Fiscal Week restriction is based on Customer exit and the rows include Hierarchy for both the queries.
I assume creating aggregates on hierarchy for the Cube can be a solution.

ESSBASE Aggregation Issue.

Hi,
I am facing a serious problem with Essbase. Iam implementing Hyperion Planning 11.1.2.2 for one of our client and first time I am implementing this version.
The aggregation is not working in my setup. I have written a rule to aggregate the hierarchy. I have tried with AGG, CALC DIM, etc. But still the same issue.
I have also tried running the Calculate web form rule file, but still aggregation is not happening.
I have also noticed that in Planning Dimension maintenance, even the level 0 members showing the consolidation operation.
Any body has clue?
Please help me as I am unable to proceed further.
Thanks in Advance.
Regards,
Sunil.

It is probably worth testing your script as a calc script and then run it directly against the essbase database using EAS, then check the data with Smart View, this process should eliminate any issues in planning or calc manager.
If you are still having problems then post your script and I am sure somebody will give you some further advice.
Cheers

NQSError: 15019, Hierarchy / Aggregates problem

Hello,
I have a problem with a hierarchy when I want to implement an aggregate fact and dimension table in the repository.
I have a logical dimension table Time, a logical fact table and a hierarchy Time with the following levels: All,Years, YearWeeks, Days).
The logical time dimension table has now two sources:
Calendar (Logical level: Day)
YearWeeks Calendar (Logical level: YearWeek)
The logical fact table has also two sources:
Day Facts (Logical level: Day)
Week Facts (Logical level: YearWeek)
I have also mapped the logical columns to the correct source tables, also for those columns which have multiple source tables.
When I check on global consistency I get the following error:
[nQSError: 15019] Table Time is functionally dependent upon level YearWeek, but a more detailed child level has associated columns from that same table or a more detailed table.
I don't know how to resolve this problem. Is there something I forgot or something I have to check? Thanks for your help!
Regards,
Stijn

hi,
you must understand that when you are making a hieracly from a dimension table the lowest level must be unique!
@@the data is at city-> country-> Region level.
in your example region level,this means, that the key for the fact must be region level and the others...
rebuild your table
hope i helped...

Hierarchy Authorization Aggregate (:)

There is a thread for this question in Bex discussion but this issue is not entirely belong to Bex so I am duplicating here also.
I have successfully set up the Cost Center Hierarchy Node variable using authorization in our BI environment. One last issue I am facing is following.
When the data appears for a user who has access to 4 out of 10 cost centers in a hierarchy node, the summarized node data is showing the totals for all the cost centers included in the node. User would like to see the subtotal of only the cost centers they have authorization for. Of course the reason aggregated values are displayed is due to the : authorization provided for Cost Center in AA object, what I am wondering is if there are any other alternatives of ":" to force the query aggregate only the values from Authorization Hierarchy Node variable. Although SAP note 727354 suggests the following
A colon authorization is not taken into account when you use a
variable of the type "Fill from authorization", since it is not known at the
time of the variable processing whether or not the affected characteristic is in
the drilldown.
I do have Authorization Hierarchy Node variable for Cost Centers in use but still the hierarchy node displays the summarized values for all the cost centers. I am hoping someone has run into this issue before me and there is a solution.
Any help will be highly appreciated.
Thanks!
-Aslam

Following is what I received from SAP, although disappointing but it is I what I thought too.
Suggestion is not to use hierarchy node variable and replace with single values.
Well the reason of choosing the hierarchy node variable was a business requirement. So I have delivered the news to business and now it will be up to them to go ahead with what comes from SAP by default (Total for all cost centers in the node regardless of user authorization) with the usage of hierarchy node or go in another direction...
Thanks everyone to take the time and provide your input.

Dear customer,
I believe this is your case. Let me know if I get this wrong.
Since the user is authorized for the TOP node, he's able to see the
aggregated values of non-authorized cost centers, although these nodes
are not authorized. Please notice that this is not an error. The
system behaviour is as designed.
If you don't want to have the aggregated values in the nodes, please
try to change your query-design and filter according to "single
values" instead of "nodes" in the authorization variable.

Problem with hierarchy change run in aggregates

Hi,
I have made changes in Cost center hierarchy (infact I have included 2 cost centers in a seperate node). After it I loaded hierarchy into BW through Process chain. Process chain uses Attribute/hierarchy change run process. Consequently Cost center hierarchy is loaded into BW successfully.
In Cost center master data, hierarchy table, i can see two new records for these added costcenters in Active status. It means hierarchy change has worked properly.
I have also read that hierarchy change run automatically reflects the changes in Aggregates, that are using Cost center info objects.
But my problem is I did not find new added cost centers in any aggregate using cost center info object. Though it should be taken care by Attribute/hierarchy change run.
Please suggest, if I make any change in source system hierarchy, then how and when it will impact aggregates ? How can I test that hierarchy change has impacted aggregates ?
Thanks and Regards
Saurabh

Hi Fede
Did you manage to solve your problem?
I have a similar situation where the technical ID of the hierarchy is set as default value for the hierarchy variable in the variable input screen.
I have noticed that if I un-check the option "Suppress 'Unassigned' Node" in the Hierarchy Attributes Settings in RSH1, then the default value is gone, but I would like to have it checked in order not to display the unassigned nodes for the end users.
Any help or comments on what you have done to overcome this problem would be jhighly appriciated.
Thanks.

Porfolio is a ragged hierarchy
Scenario is a flat hierrachy
Instrument is a flat hierarchy
PNL values are loaded for instruments at different points in the portfolio hierarchy.
Then want to aggregate the PNL values up the portfolio hierarchy into AGGPNL, which is not working the loaded PNL values should remain unchanged.
Have tried defining the following formula on AGGPNL, but this is not working.
IF (@ISLEV (folio,0))
pnl;
ELSE
pnl + @SUMRANGE("pnl",@RELATIVE(@CURRMBR("portfolio"),@CURGEN("portfolio")+1));
ENDIF;
using a calc script
AGG (instrument);
AGGPNL;
Having searched for a solution I have seen that essbase does implicit sharing when a parent has a single child. This I can disable but this is not the sole cause of my issues I think.

The children of F11 are aggregated, but the value which is already present at F11 is over wriiten and the value in F11 is ignored in the aggregation.^^^That's the way Essbase works.
How about something like this:
F1 +
===F11 +
======F111 +
======F112 +
======F113 +
======F11A +
===F12 +
======F121 +
======F122 +
===F13 +
======F131 +
======F132 +
Value it like this:
F111 = 1
F112 = 2
F113 = 3
F11A = 4
Then F11 = 1 + 2 + 3 + 4 = 10.
Loading at upper levels is something I try to avoid whenever possible. The technique used above is incredibly common, practically universal as it allows the group level value to get loaded as well as detail and agg up correctly. Yes, you can load to upper level members, but you have hit upon why it isn't all that frequently done.
NB -- What you are doing is only possible in BSO cubes. ASO cube data must be at level 0.

Aggregates in Production System and Change Run Hierarchy

Hi All,
Can anybody tell me, Why should we create Aggregates in Production System nd How?
What is Change Run Hierarchy nd How to perform this?
Reply back me to [email protected]
Regards,
Kiran

Hi Kiran,
Aggregates are nothing but a subset of your Infocube... when a query is executed, it firstl looks for the presence of the data in your aggregates and if found then it fetches the reocrds from there itself.. Else not, it'll search teh entire infocube and then fetch the records which is at a high risk of time consumption and the performance of the Query execution slows down or becomes worse significantly.. for this purpose, you build aggregates.. how do you decide whether you should go for aggregates or not is based on the following criteria...
if the %Data Base time is > 30% and if the KPI ratio (selected to transferred records) is > 10, then you go for the aggregates... you can get these details in the ST03N transaction by choosing Expert mode and selecting BI Workload... you can find all the statistics related to the Query execution starting from the front end time to db time/...
thats all about your aggregates...
Attribute or Hierarchy change run is done so that any changes to your Master data Attributes will have to get effected in terms of your reporting...
say for eg.. ur name is XYZ and loc is in India.. this is how it'll be reflected in your reporting also.. but at a later point in time, if you have changed your location from India to Europe, then for that to be reflected in your reporting, you'll have to perform an Attribute change run for that Characteristic...
Hope it solves your issue..

Aggregates based on Nav Attribute Hierarchy

Hi,
I have naviational attribute hierarchy based on created by and enabled as navigation attribute from Infocube. So for each transaction the created by pulls up the corresponding nav attribute from master data.
I have enabled the Created By nav attribute hierarchy in the query and the rendering of the hierarchy is really slow and the performance went down.
What is the best way to increase performace creating aggregates at Created by level or Created by Nav attribute hierarchy level?
Is there any document available on this topic?
Thank you
Arun

Hi Arun,
I don't know if this can be useful, but take a look to OSS Note 738098 'Performance problems with hierarchies'..
Hope it helps!

For direct activation of hierarchy, Aggregates have to be deactivated

Hi,
There are 2 monthly master data hierarchies loaded.
We face some problem while loading the hierarchies.
Now the 2 hierarchies are seen as Modified version.
When I try to activate the hierarchies manually I receive the below message
"For direct activation of hierarchy, 0042 Aggregates have to be deactivated"
with 2 options as:
1 Prebook activation
2 Activate directly
What are these options?
Will affect on aggregates?

hi,
Activate directly wlll directly activate the hierarchy....
Prebook for activation will capture it and it will be activated later at the time of the chnage run.
Always prefer Prebook for activation...
hope this helps.

Mahesh
