OLAP Universe

New to Universes ***
i have created an OLAP universe from MSAS 2005 cube. Each dimension object contains a detail attribute named KEY0. However, I can see the value of KEY0 only on the "(All)" object and all have a value of 0. The other KEY0 details can be queried, but are empty.
Is KEY0 the 'unique' member value and why can't i see it?
Many thanks...

Hi,
There is no additional license required to use OLAP universes excepted for SAP NW that requires SAP Integration kit.
But if you want to use OLAP universes on any OLAP data source supported by the product you need to install the middleware before to create connections.
For Essbase you need to install a compatible Essbase client version dependening on your Essbase server.
If you are using OLAP Intelligence you need an addtional license.

SAP BW OLAP Universe performance issue

Hi,
Based on BO recommendation, I created a universe on top of a big BEX query which included all characteristics and key figures from a cube. I then created a webi report with 5 characteristics and 1 key figure from this universe. I also create the same report in BEX query designer(same number of objects). I ran both. The Bex query completed under a minute and the webi report took more than 12 minutes to run. I did a bunch of other test with different number of objects combination and saw similar differential in query performance.
I did a trace using 'sm50' and saw the open SQL submitted to BW from BEx was very different from what got submitted from the webi report. Here is what I saw in pseudo code.
Bex:
select dimension1.blah, dimension2.blah, dimension3.blah, dimension..... sum(measure)
from dimension1, dimension2, dimension3, dimension..... factTable
where dimension1.SID = factTable.d1SID
and dimension2.SID = factTable.d2SID
and ......
and (query filters)
OLAP Universe
select dimension1,blah, dimension1.SID
from dimension1, factTable
where dimension1.SID = factTable.d1SID
select dimension2,blah, dimension2.SID
from dimension2, factTable
where dimension2.SID = factTable.d2SID
select dimension3,blah, dimension3.SID
from dimension3, factTable
where dimension3.SID = factTable.d3SID
It seems the OLAP universe was querying the BW cube one dimension at a time and then somehow piece the result sets together to form the final result set. Dimension tables join to the fact table without any filter definitely causes performance issue. Beside, I have no idea why the query requests are submitted to the BW system like that.
I looked in varies forums and found no similar issues posted by others. Has anyone had any performance problem with there OLAP universe? Is this a matter of configurations?
My envrionment:
SAP BW 3.5
BOXI 3.0
ORACLE DB (version ??)

Hi,
You cannot compare a BEx query and a universe query by just comparing the trace.
BEx query makes ABAP calls and universe query makes MDX calls;
Moreover there is only one MDX call sent to SAP, what you have noticed is that there is one MDX call to retrieve member for a given characteristic whereas a prompt has been set on.
Last, Web Intelligence consume only flattened data (row sets) wheras BEx consume data sets.
That means that there is a flattening operation between SAP OLAP engine and the data sent to the Web Intelligence document.
A fix have been developed for a customer to improve performance on Web Intelligence queries, this fix will be available for all customers in SP2 planned in June 09.
Here is a a brief summary of what the fix provide:
- Provide data directly from SAP server to Web Intelligence document. Avoid unnecessary conversion steps: row set --> data set --> row set
- Eliminate redundant sort operations
- Other optimization operations

Webi Reports Hyperlinks on top of OLAP Universe

Hi Webi Gurus,
my BoBJ version 3.1 sp3
BW-OLAP universe.
I checked below Link for the solution, but couldn't
get answer, as these are based on relational universes.
/people/erika.atencio2/blog/2011/04/14/creating-hyperlinks-between-webi-reports-in-infoview
I have a OLAP universe. On top of it, there are two reports
One parent report and one child report.
Question: I have a column called Auction Id on parent report.
Now, when I click on any of the Auction Id values, child report
should only bring data for that Auction Id alone and not other Auction Ids.
In the child report, I have Auction Id as query filter.
Now while in Webi's Interactive Mode, I chose the option
Select Column--> Create Hyperlink --> Link to a document -->
Document prompts: Prompt User in runtime.
This option works fine.
However, when I change the Document Prompt to:
Select Object (or) Build Formula
report throws MDX error, during run-time,
Please suggest.
MDX error:
========================================================================
The query failed to execute with the error Value for the Characteristic.....WIS 10901
==================================================================================
Regards,
AK

Still getting error...I tried this
>> 1. In the detail webi report, create a query filter for AuctionID and use Equal operator. Give the prompt text as ActionID.
AK: Done
>> 3. In the column properties, in the display section select display cell content as HTML.
AK: Done
When I provide the URL and Parse it throws following error.
"Invalid identifier a at position 15. (WIS 10022) "
I gave following URL and parsed it.
="<a href="http://sapbojdev:8080/OpenDocument/opendoc/openDocument.jsp?
iDocID=18774&lsSAuction ID="URLEncode([Auction ID])"&sRefresh=Y
Q: Is there any problem with syntax?
Q: Secondly, for OLAP universe based webi report , can't we use the hyperlink option:
Link to Document
Thanks,
AK

Setting a Prompt value for KeyDate in WebI on SAP OLAP universe

I have a webi report which has as its dataprovider a query against an SAP olap universe against a BEx query which has the KeyDate parameter exposed.
Iu2019d like to get at this prompt from the SDK.
In infoview if I run the report it pulls up the keydate prompt (a special dialogue which seems to be implemented as part of the connection definition) - this prior to pulling up the full prompts dialogue and showing all universe based @prompt filters. In WebI I can see the prompt value entered using =UserResponse("dp.kd.value") . So it does seem to see the keydate as a prompt of some sorts.
I've got a little jsp that allows me to set prompts very nicely (and packeaged as a jar in the CMC that schedules ok as well) but when I put it against a report with a key date u201Cpromptu201D it just wonu2019t see it. When I call a getCount() as below it returns 0.
oDocumentInstance.getDataProviders().generateQueries();
Prompts oPrompts = oDocumentInstance.getPrompts();
out.print(oPrompts.getCount());
This is all in an attempt to get around the scheduler limitations of key date which would give me two queries, two universes and two reportsu2026 one report for scheduling (using a customer exit to set key date) and a second for user refresh (with a prompted key date) which would all be rather messey to say the least!
So any cunning ideas on how I can get hold of this key date thingymebob in the SDK?
(ps. "Fixed in V4" would be nice to hear as an aside to thisu2026 In playing with the ramp up Iu2019ve got the same issues however so Iu2019m not to hopefull )
Thanks!
Jeremy.

Hi,
First I think you have to create a support ticket because normally the object in the universe must be generated with data data type nad it is not the case.
We are awere of some limitations with data types.
Secondly, if you want to have users entering date you have to specify date in the prompt data type like this:
<OPTIONAL><FILTER KEY="[PERIOD SD].[DB Full Date].[DB Full Date]"><CONDITION OPERATORCONDITION="Equal"><CONSTANT CAPTION="@Prompt('Enter Date ','D',,mono,free)"></CONSTANT></CONDITION></FILTER></OPTIONAL>

Calendar Prompt in OLAP Universe does on resolved.

Hi,
I am using BO XI 3.1 with latest fix pack.
I have created a OLAP universe based on SSAS 2005 Multicube for reporting using WebI.
I have a date field in my database but when i but when i created a Universe based on that cube the date field became of type STRING. One of my requirement is that i want a calendar popup in my WebI report when i create a filter on top of that date field.
So i manually changed the type to Date format in Universe Designer in order to see the calendar popup in webi report.
My concern is when i select a date value from the calendar it does not work and i cannot see the data for that date if though the data exist for that. But when i manually enter the date value for that filter changing back the data type as CHaracter in the Universe it works and i can the see the data . The date format i am using is M/D/YYYY which is the same as calendar prompt.
Why we notice this such behavior for the date field in the WebI and every time i want a calendar prompt i have to change the date type to Date and if i have to manually enter i have to change to Character.
Kindly suggest .
Regards,
Vibhav.

Hi,
this forum is about the Integration Kit for SAP and you are referring to a MSAS OLAP Universe. Would suggest you enter this in the Universe forum.

OLAP Universes - Based on BEx Query - Month and Previous Month Functions

Hi,
I created a Universe based on SAP BEx queries and I like to create a filter so that I use in Web Intelligence report to run for "Previous Month" data always. There are "Date" filelds in BEx Query(No Month info only date data). I have no knowledge of SAP BEx Queries and new to OLAP universes. Could you help.
How to create filter that show Previous Month.
Nanda Kishore
Edited by: Nanda Kishore B on Dec 26, 2010 6:15 AM

The easiest way (but NOT the most efficient one) is to create a local variable (Dimension) in your report with the following code:
=if (Month(CurrentDate())=1 AND Month([[MyDate]])=12 AND Year([[MyDate]])=(Year(CurrentDate())-1)) OR (Month(CurrentDate())>1 AND Month([[MyDate]])=(Month(CurrentDate())-1)) then 1 else 0
where MyDate is the field from your query containing the data information
Activate the report filter area in your report design panel by pressing the Report filter icon and drag and drop your variable there and apply it to the entire report. Filter value 1 and you will get the data for the previous month.
Keep in mind that this approach is not optimal especially if you do have many rows of data delivered to your WebI report because filtering takes place only AFTER the data is retrieved. The Best practice here is to work with BEx variables.
How many rows of data does your WebI report normally fetches?

Error querying OLAP universe based on BEx query

Hi all,
I have a problem extracting larger (more than 80 000 rows) amounts of data through querying an OLAP universe with WebI.
The error is:
Query 1 - NAME_OF_THE_QUERY
A database error occurred. The database error text is: Error in MDDataSetBW.GetCellData. &INCLUDE INCL_INSTALLATION_ERROR. (WIS 10901)
The error occurs when I define larger scope of analysis in the query (four levels). With more modest scope (three levels or less) it's working OK. I need larger data set (more than 200 000 rows) to be populated at night through scheduling the report. We can't afford shrink the scope of analysis because it will hit the BW server during the day when it's needed by other users.
Besides this the speed of the report refresh is very slow - more than 3 minutes per just 400 rows of data. I'm still unable to identify the source of the problem with this slowdown. Executing the same query over the web through the SAP BW BEx Viewer is much much faster - just 3 seconds. Maybe the reason for this is that the BEx viewer aggregates data on the higher level of the hierarchy rather than down to transaction level (like we do by expanding the scope of analysis).
Anyway, if anyone have ideas about the error above I'll be very grateful if you share your thoughts. Thanks!
Our environment:
BO EDGE BI 3.1, standard
SAP BW 3.0
SAP Integration Kit (all transports installed)
BW user with full access

Ingo,
Could you point me to an official SAP document regarding the 1 million cells limitation, which describes the exact version and patch level for SAP BW which removes this limitation? It will be very helpful for me because I have to convince the client to migrate BW from 3.0 to 7.01 if it will solve this limitation.
Thank you in advance!
Ivan
BTW I have installed SP2 + FP2.1 and now the SAP integration is not functional, but I have opened another thread for this problem.

Edit an object's select statement of OLAP universe SAP BW

Hi everybody
I am new at working with Olap Universes BW, and I have to edit one universe SAP BW, I don't know if I can to use substring function on a select statement, for example substring([0D_DIV].[LEVEL01],5,5), I try to use this function but I have a error,
Could you help me? I need to returns part of a string, is correct to do it on a universe or is better to do at BW.

Hi,
First of all I recommend you read the documentation that gives you information about OLAP universes and especially SAP BW universes.
I also recommend to download documents related to SAP universes deployment, administration and customization:
[OLAP Universes - how to samples and recommendations |https://wiki.wdf.sap.corp/wiki/display/globalregions/OLAPUniverses-howtosamplesand+recommendations]
[SAP Integration |https://wiki.wdf.sap.corp/wiki/display/globalregions/SAP+Integration]
Now you can customize expression using MDX in OLAP universes. MDX expressions must be enclosed with <EXPRESSION></EXPRESSION> XML tags.
Unfortunately SAP BW MDX does not support calculations that return string or date values.
The onlyway to return string is to use NAME or UNOIQUENAME attribute.
See answers I already in the forum: [Forum answer |Re: Create new dimension on top of SAP BW data]

How to use string functions (substr or ltrim or replace) in OLAP universe.

cost element (0COSTELMNT) - 10 CHAR
Controlling area (0CO_AREA) - 4 CHAR
[0COSTELMNT].[LEVEL01].[[20COSTELMNT]].[Value]
cOST ELEMENT is compounded/prefixed with Controlling Area. I just want to see cost element without conrolling area in the BO report.
Currenlty BO unierse is build based on bex query. I am able to suppress the compounding object in bex query by chaning controlling area to 'No display'. But still BO Webi report displaying compounded values in the report. (Bex report works as expected)
eg: Current display in reort.
controlling area/cost element.
AB00/2222
AB00/2223
AB00/2224
Wanted like below:
2222
2223
2224
I think by using string fucntions (substring, ltrim or replace etc.), I can get the required result. But I am having issues with syntax. I have used like below.
substr(0COSTELMNT ; 5 ; 10)
substr(0COSTELMNT; 5 ; Length(0COSTELMNT)-5)
substr(0COSTELMNT; Pos(0COSTELMNT;"/")+1;10)
ltrim(0COSTELMNT,'AB00/')
What is the syntax for substring/replace functions in OLAP universe. Technical name of cost element in OLAP universe is [0COSTELMNT].[LEVEL01].[[20COSTELMNT]].[Value].
I want to fix this at universe level not at report level as i am using cost element in filter/variable section of the report. Please provide me syntax for above example.

Hi,
In fact SAP BW MDX supports limited string manipulation and only with NAME and UNIQUENAME attributes.
Here are some samples that you can use in universes:
MID([0COSTELMNT].currentmember.NAME,1,4)
LEFT([0COSTELMNT].currentmember.NAME,2)
RIGHT([0COSTELMNT].currentmember.NAME,3)
MID([0COSTELMNT].currentmember.UNIQUENAME ,1,4)
LEFT([0COSTELMNT].currentmember.UNIQUENAME ,2)
RIGHT([0COSTELMNT].currentmember.UNIQUENAME ,3)

BO performance issues on OLAP Universes

Hi All
I am working on BO XI 3.0 and installed the SAP Integration Kit for Windows 3.0 version.
I have built OLAP Universe based on BW cubes and reporting on the Universes using Web Intelligence.
I am facing performance issue when trying to query on OLAP Unvierses and the query is taking ~10 mins to fetch the data. I have installed the FP3 for BO XI 3.0 and there is no improvement as such. Could anyone help me on this issue.
This has been a long standing issue and is causing a hindrance to our deliverables.
Regards
Chetan

Hi Ingo,
We are also currently facing similar kind of performance issues.
We have sap bw Infocube and bw query on top this we have BO Universe.
As per best practices document "the WebI query panel definition is what defines the "MicroCube" and thus the MDX query which is executed on SAP BW".
It means that the actual query performance / query execution time / memory consumption is directly related to number of objects dragged into WebI query panel not in SAP BW query.
if this is true then what is the reason not to have all infoObjects / keyfigures of InfoCube in a single sap bw query?
I found another Best practices document which says that "DO NOT build one query per infoProvider because elements can add processing time even though you are not using them into the Web Intelligence Report
In one statement it says that the WebI Query panel definition is what MDX query going to execut on SAP BW and in other statement it says that the elements in SAP BW query can add processing time even though we are not using them in Web Intelligence Report*.
Appreciate if you can clear these contradicatory statements.

Row Level security in OLAP universe

Hi,
We have a OLAP universe based on a BeX query and we are planning to implement the row level security on it.
As it is not possible to use the normal @BOUSER in the OLAP universe, what is the way to implement the same?
Is it possible to have it in the BeX query itself? Any thoughts on this please.
indus

Hi,
right now you can not implement row level security in an OLAP Universe, you need to setup BI Authorizations and use Authorization variables in the query.

OLAP Universe creation process questions and proposals

We have created an OLAP universe based on a BW-Query. The automatical creation of the OLAP universe does not produce a satisfying result.
We are working with the latest available releases (BOE XI 3.1 SP2 and SAP Integration KIT SP2, SAP BI 7 EHP1).
We have detected that all dimension objects store the name instead of the key field.
Example:
Customer Dimension Object (L01 Customer) = Customer Name
Customer Key Detail Object (L01 Customer Key) = Customer Number
Customer Name Detail Object (L01 Customer Name) = Customer Name
This is not usable for end user because of the following reasons:
1. The detail objects can not be used for merge dimensions, so it is not possible to merge on the supplier number.
2. If you filter on the dimension object you will only see the text in the list of values (LOV) and it is not possible to edit the list of values in the universe to add the supplier number to the LOV as it is possible in relational universes
3. If the user select the detail object always the dimension object in inserted into the report query
4. The "Business Explorer" general setting "Display" of an InfoObject has no effect on the OLAP universe dimension object. If you change it to key always the text is shown. Even if you change the "ValueDisplay as" in the underlying BW Query to "key" is has no effect.
5. The renaming of the L01 object to blank is not possible. You need to rename to " " and then remove on each object the blank.
So we need to modify manually every universe to change the "detail key object" to a "dimension object" and the "detail name object" to reference the new "dimension object" with the key. This manual process has a huge work effort in time. Is there a better solution or enhancements planned in the next releases?
Additionally there should be an option to disable the automatic creation of each characteristic as a subclass in the universe. A wizard should ask if a subclass should be created or not for each characteristic. Currently there are to many subclasses generated which were mostly not needed.

Hi,
First of all I would say u are lucky to start with SP2. Because whatever modifications you do in Universe those are retained.
We had a big trouble in using BOXIR3.1 FP1.7.
Anyways.. Back to your Questions and My asnwers for those:
1. The detail objects can not be used for merge dimensions, so it is not possible to merge on the supplier number.
Ans: True, Dimension object always shows Short text values by default. but if you can create the logic at SAP BI query level to map short text with keys then your problem will be solved.
2. If you filter on the dimension object you will only see the text in the list of values (LOV) and it is not possible to edit the list of values in the universe to add the supplier number to the LOV as it is possible in relational universes.
Ans: True u cannt edit LOV, but alternate solution to it is create the variable in SAP BI Query, that will appear as prompt in universe which will display the List of values with Key as well as Description.
3. If the user select the detail object always the dimension object in inserted into the report query.
Ans: Logically its correct, because Detail object is always associated with Dimension. Buit if you dont want that dimension in query you can remove that dimension by dragging back.
4. The "Business Explorer" general setting "Display" of an InfoObject has no effect on the OLAP universe dimension object. If you change it to key always the text is shown. Even if you change the "ValueDisplay as" in the underlying BW Query to "key" is has no effect.
Ans: In Query designer even if you ValueDisplay as "Key", but at Object level if there is Text and Key associated for perticulat Infoobject, then so by default the dimension will show the Text and there will be seperate Detail object in universe for Key.
5. The renaming of the L01 object to blank is not possible. You need to rename to " " and then remove on each object the blank.
Ans: Yes this is a big trouble.

Nisha

BW OLAP Universe connection error after applying BOE XI3.1 SP2

Hi,
We installed BOE XI 3.1 SP2 today on the server, and since then we are not able to execute the WebI reports built on top of BW OLAP universe. The error message is - An error occurred while trying to load the provider for transport sap. Failed to load library mda_sap. System error message.
The same error message appears when I test the universe connection.
Has anyone come across this issue? Your help is really apprecaited.
Our system config is Windows 2003 server, 64 bit, SP2.

Report on olap universe (integration kit) fails by WEBI and it runs by Rich

I've implemented the integration Kit and an OLAP universe query based and it runs.
I've a problem on a report that runs via Rich Client and fails via web client.
We are on BI 7.0 sp 19. Is it necessary to upgrade to BI 7.01 SP03 or SP04 ? We've seen your interesting document about the improvement of perfomance of BI 7.01 SP04 but we'd like to upgrade our BI system 7.0 in 2 months and not now.
Thanks in advance.
Best Regards.

Hi Sebastian,
The BO XI 3.1 Fix pack Level is 1.7. We have activated traces but we don't know if the traces are java.
We have the problem with reports with a large quantity of data, in report with a low quantity of data webi runs.
OSS ask us to evaluate the upgrade of our SAP BI to the EHP1 03 but it requires 2 weeks and we'd like to evaluate all alternatives before to do it.
Thanks in advance.
Best Regards.

Behavior of BEx Query Attributes for webi on OLAP universe: Including 1 attr to Query!

My webi report is based on an OLAP universe (.unv) which is based on a BEx Query. I need an attribute field from an info object. But when I include that attribute in my BEx query in free characteristics pane…… Every single attribute in that info object comes over to the universe.
Is this the expected behavior?
How can I ensure only the attribute wanted comes over and not all the attributes of the info-object.
I am using BO 4.0SP4.

Attribute level restriction of an InfoObject is not possible in BEX Query and the same reflects in the Universe.
You can use attributes of an infoObject which you wanted on WEBI Report Level.
