Perf issues with Time series function in OBIEE

Attached is the SQL:

AND SAWITH6.c3 = '2009 / 11'
AND SAWITH6.c2 >= SAWITH3.c2
The SAWITH3 and SAWITH6 dimensions using time series fuctions are causing a full table scan on W_GL_BALANCE_F and W_GL_ACCOUNT_D . Though we are interested in just getting 2009/11 data; the queries generated by time series function TODATE is taking us against entire W_DAY_D data and is causing several performance issues.
W_GL_BALANCE_F table has index on GL_ACCOUNT_WID and BALANCE_DT_WID.
How can we force to use index on these columns for better performance.
Please advise us on the right approach to improve performance.

Srini Pendem

Hi Srini,
I've had quite a bit of performance issues with ToDate and Ago. I tended to create materialized views on my fact tables that would materialize those values as columns and that way I would avoid having to use the ToDate or Ago functions. Is there any chance you can implement a similar solution and bypass the time series functions entirely?
Just to check, those tables belong to BI Apps, right? If so, you can log an SR about the performance issue since it's an issue with the model that Oracle sold you.
Good luck!

Balance for open periods in a time series enabled cube

Hi,
We have a request to calculate balance for open periods in a time series enabled cube, I don’t there is any inbuilt function for this.
Any ideas on how to calculate this without adding new members/formulae in the time dimension. Currently we compute this in the report
EX:
BOY(May) = Jun+Jul + … + Dec
Thanks,

You will have to add a member somewhere. Suppose you add it in scenario, then you could use sumrange for the current member range offsetting the current monthe by 1 and use null for the end month wich gives you the last month in the time dim.

Order Series key figure is considered as Time Series

Hi Gurus,
I'm adding a new Key FIgure (Order type) into a copied version of SNP Planning Area.
I have assigned category and therefore category group and, applied similar settings like other KFs (Planning Area, Planning Bokk...). The thing is when going into Data View, it's not behaving as an Order Type and saves its data as a Time Series. Thus no "detailed information" appears when I right-click in the bucket.
Do you have any idea where my settings are wrong?
PS: I'm using SCM 7.0 module version
Many thanks & regards,
David

Hi David,
You defined the keyfigure as order keyfigure.So when enter value in this keyigure system tries to create order as per keyfigure function which is assigned to this keyfigure.please note that not all the keyfigure functions creates the order.
If your keyfigure function is anyone of the following then system creates the stock transaport order:
4001
4015
4002
4007
4006
4013
4018
4019
4020
If your keyfigure function is anyone of the following then system creates planned orders:
2001
9020
2007
If your keyfigure function is anyone of the following then system creates forecast:
1002
1003
1004
Hope this information will helps you.

Sunitha

Time-series Chart

Warning, CR Newbie here so this may be a stupid question. I am evaluating the trial version of CR to see if it will be a good fit for an upcoming project. I've seen some related posts in the SCN, but no answers that quite fit.
I'm looking to create a line chart (or a scatter chart) with time-series data. My dataset includes a time stamp field (yyyy-MM-dd hh:mm:ss) and some floating-point temperature values like this:
2014-05-01 08:00:00, 123.4, 115.1, 109.2
2014-05-01 08:00:10, 123.6, 116.0, 109.8
The desired outcome has the date / time along the X-axis with data points spaced proportionally in the X dimension and plotted in the Y-dimension according to the temperature. The interval between the time stamps is not always the same, so numerical scaling is required on both axes. The desired chart would show a temperature scale along the vertical axis, three trend lines for the three series of temperature data and times shown on the X axis label.
I've played with several options in an attempt to make this work. On the data tab, it would seem I would want to select "on change of" and then my time-stamp field. However, with this selection, I can only use summary values and end up with a chart with a single data point for each series. I don't need or want any summary calculations carried out on the data, I just want to plot it so I can look at a trend over time. I can get trend lines if I select "for each record" on the data tab of the wizard, but then my X-axis is meaningless and the horizontal scaling is misleading unless the interval between my samples is constant.
I would welcome any suggestions on how best to accomplish this with Crystal Reports.
Thanks for reading.

Jamie,
Thanks for continuing to reply. I am getting close, but still no success.
Here is the procedure I've followed and problem:
Put chart in RF section
Start Chart Expert
Chart Type = Numeric Axes, subtype = Date axis line chart
Data tab
On change of datetime field
Order... ascending, printed for each second
Values avg of my data fields (must select summary when on change of is used)
Right-click on X-axis label, select Group (X) Axis Settings
Scales tab: base unit, major unit and minor unit can only be set to days, months or years
I cannot set the minimum and maximum date with resolution other than day
Right-click Chart, select Chart Options...Axes tab: show group axes set to show time scale
No matter the setting I use, I can't find a way to adjust the resolution of the time scale lower than days.
I tried using a formula to extract only the time portion of my datetime field. I used that as my "on change" data series, hoping maybe CR would automatically recognize I was looking at a fraction of a day if I did that. No good - now it gives me a date scale with the dates showing up as the beginning of the epoch, but I can still only get resolution of integer days.
Thanks for your patience and persistence.

TODATE time series function in OBIEE 11g

Hi,
I have a problem with time series function. I have month level in time dimension hierarchy.
I have used below expression to get month to date results in my reports.
column
expression----> TODATE(fact.measure, hierarchy.Month level);
when i am using this column in my reports it is showing null values. The below error i am getting in view log files
----------------> Converted to null because it's grain is below query's grain
Note: Here i have measures, year,qtr,month,day,shift,hour in single physical table in physical layer.
Is it a problem to have measures and time columns in a single physical table?
Please let me know if you have any solution.
Thanks,
Avinash

Yes, it shud be a prob. Try using seperate tables for fact n timedim

Regarding Time Series Graph in OBIEE 11g

Issue in new macro calculating values in time series in CVC

Hi friends.
I'm new in APO.
I have a problem with a new macro in CVC which calls up a FM to calculate and store data.
This new macro calculates the selected data in time series (TS) and e.g. we select 3 days to make calculation with this macro, the first selected day in TS is ignorated.
We created this macro to do this calculation when user enter some manual values and want it to be calculated in the deliver points in CVC, by TS.
This macro calls up my Z function which internally calls up a standard FM '/SAPAPO/TS_DM_SET' (Set the TS Information).
Sometimes, this FM, raises error 6 (invalid_data_status = 6), but only when I user 'fcode_check' rotine together.
After that, we call the FM '/SAPAPO/MSDP_GRID_REFRESH' in mode 1 and 'fcode_check' rotine in program '/sapapo/saplmsdp_sdp'.
Firstly, I thought it could be dirty global variables in standard FM so I put it inside a program and called it by submit and return command. But now I think could not be this kind of error because it did not work. And inverted the results, and now only first line os TS get storted and change in CVC.
It's a crazy issue. Please friends. Guide me for a solution!
thanks.
Glauco

Hi friend. Issue still without a correct solution yet.
A friend changed the macro adding another step calling the same function. Now this macro has two calls in sequence to same FM. Now it's working, but we can't understand why it's working now.
It's seems like dirty memory in live cash.
Nobody knows how to solve this!
Glauco.

How to set Dynamic Time Series in Planning application

Dear All,
I am having an issue by setting up dynamic time series (Y-T-D). I have set up at generation level 4. In our application the hierarchy of dimension Period is as follows.
Yeartotal -> HY1 -> Q1 -> Jan, Feb, Mar
Consider the following example
Jan -> 100
Feb -> 200
Mar -> 300
If I want to retrieve "Y-T-D Feb" the result should show me the sum of Jan & Feb in this case it should be 300. What is the syntax of retrieving YTD in smartview.
In our application "Year" dimension name is "Year". How can I rename this dimension name if this is the requirement.
Thanks in advance.
Regards,
Sami

The format in Smart View would be Y-T-D(feb) more info at http://docs.oracle.com/cd/E17236_01/epm.1112/sv_user_11121102/ch17s02s02.html
you will need to rename Year to something like Years, it depends if it is a classic or EPMA to how you rename it.
Cheers

How to apply time series function on physical columns in OBIEE RPD

Hi,
I know a way to apply time series function(Ago and ToDate) by using existing logical columns as the source. I have set the chronological key and created time dimension. In the expressiion builder for the same Time Dimension appears at the Top so that we can use its level.
But I couldn't apply a time series function when i have to create a logical column using physical columns. In the expression builder for the same, Time dimension does not appear in the list. Neither can i use any column from the time dimension. Please let me know a way to do it.
Thanks.

Time series functions are - by design and purpose - only valid for derived logical columns and not useable inside physical mappings.
If you want / need to do it on a physical level, then abandon the time series functions and do it the old-school way with multiple LTS instances.

Drilldowns on measure columns based on time series functions.

Guys,
I am new to OBIEE and i need your Help!! I have a dashbaord report which shows the sales USD for the colums below.
REGION , PRIOR MONTH , CURRENT MONTH PRIOR YEAR , CURRENT MONTH PRIOR YEAR MTD , CURRENT MTD , ACTUALS YTD.
All the measures are logical columns caluculated in the RPD using the Time Series Functions. The dasboard report has a Prompt Calender Date and all the measure values are caluclated based on the date entered in the prompt.
For example if the Calender Date on the prompt is 5/31/2011 then the value for the PRIOR MONTH will the sales for APR-2011 and the value for CURRENT MONTH PRIOR YEAR will be MAY-2010 and so on.
The business requirement is to provide the drill down capability on these measure columns. When i click the sales number on the prior month column it should give me all the detailed transactions for the month of APR-2011 considering the prompt for calender date is 31-MAY-2011.
I have provided drilldowns based on the Navigation using the column interatcion but i am unable to understand how to provide the drilldown on the measure columns using the time series functions to caluclate the sales for PRIOR MONTH. CURRENT MONTH PRIOR YEAR...etc.
Please Help!!!
Thanks,
Sandeep.

1. Create an alias fact table (Year Ago) to pull last year value.
2. Extend your fact table to store another measure (last year sales)
3. Based on volume of granular data and query pattern on year ago measures, you may create aggregate fact tables.
hope this helps.

OBIEE 11g Time Series Function

Hi All,
I am trying to compare this year to date sales to last year to date sales and this code is not working:
TODATE(<Measure>,<Time_Level>) For bellow syntax we are getting an error Formula syntax is invalid.
TODATE("Fact - Sales Order Lines"."Net Ordered Amount", "Time"."Enterprise Year").
Is the above example wrong?. Please provide one example for Time level value.
Actually what should be the value for second parameter (Level)
Thanks in advance.

Hi,
What error are u getting? make sure year hierarchy level on u r time dimension and then test it
example: (via bmm)
ToDate("Subject area"."Presentation table"."measure Column", "Subject area"."Time dim table name"."year dimensional hierarchy" )
ToDate("Sample"."Fact_ICA"."Sales_Amt", "Sample"."Period"."Year" )
<<Measure>> represents the logical measure column from which you want to derive. In this example, you would select the measure "Dollars" from your existing logical fact tables.
<<Level>> is the time series grain you want to use. In this example, you would select "Quarter" from your time dimension.
Refer section About the TODATE Function
http://docs.oracle.com/cd/E23943_01/bi.1111/e10540/dimensions.htm#BABBEGHH

Time series functions are not working for fragmented logical table sources?

If i remove that fragmented logical table sources, then its working fine.
if any body know the reason, please let me know.
thanks and regards,
krishna

Hi,
is because the time series function are not supported for the framentation content, see the content of the oracle support:
The error occurs due to the fact the fragmented data sources are used on some Time series measures. Time series measures (i.e. AGO) are not supported on fragmented data sources.
Confirmation is documented in the following guide - Creating and Administering the Business Model and Mapping Layer in an Oracle BI Repository > Process of Creating and Administering Dimensions
Ago or ToDate functionality is not supported on fragmented logical table sources. For more information, refer to “About Time Series Conversion Functions” on page 197.

Gianluca

Use of time series functions with horizontally fragmented fact tables

Hi Guys,
in OBIEE 10g it wasn't possible to use time series functions [AGO, TO_DATE] on horizontally fragmented fact tables. This was due to be fixed in 11g.
Has this been fixed? Has somebody used this new functionality? What the the limitations?
Tkx
Emil

Hello,
Can you give us some examples for "horizontally fragmented fact tables", we can tell you whether we can do that or not?
Thanks,
