Median aggregation on various time series

I have a requirement to compare a measure, project milestone median days in these time brackets: current quarter, previous quarter, previous two quarters, YTD (year to date), YTD (excluding current quarter), previous year and previous two years, all years up to previous year.
I have built a time dimension of All, Year, Quarter, Month, Date. With time function and logical level, I can get median days for most of these brackets, except: previous two quarters, previous two years, YTD(excluding current quarter) and all years(up to 2009). I can get these median day aggregation for using the filters on separate requests, but then I cannot get all these fields in one request, side by side.
Is there a way to build the time dimension so I can use the time function for these "peculiar" time periods?
Thanks,
Shining

May be worth looking this post -

I am not sure, what you want to achieve, but it should be possible against time series too.

Issue with nested aggregated in time series

Hi Experts,
I have a small requiremnt using time series.
eg : (sum(current year4:Quarters bookingamt)-sum(previous year4:Quarters bookingamt))/sum(previous year4:Quarters bookingamt)
Bookingamt is My measure Name.
how do we implement above logic can please help regarding this.
Thanks,
C Mahesh

Hi Mahesh,
These functions help to obtain the data analyzed based on the time. There are two types of Time Series in OBIEE viz..
1) Ago
2) To Date
Following are the prerequisites and procedure to create time series function in OBIEE RPD.
a) Create a dimensional Hierarchy (ex: YearàQTRàMonth) and convert it to the time dimension. DC on hierarchy and check the box time dimension.
b) Define the Chronological Key. A chronological key should always be the lowest level in the table and the data in it should be in the format of 20090102 or 200109 (year, month format). DC on level (preferred/last—detail) go to KEYS tab and check chronological key.
c) Duplicate the existing column, rename and specify the formula for the column.
1) Ago: This function when specified in any column displays data that is month ago, 2 months ago depending on the specified formula. DC on new column check use logical columns and click on exp. Builder. In the left column select functions and then time series and then AGO. Then in metric go to logical tables and select metric and in level go to time dimension and select month (1 month ago) and give the period as 1(since it is 1 month ago) then transfer two new columns to presentation layer
Ex: sales: 100,200,300 à -, 100, 200 (1 month AGO).
2) To Date: This functions allows us to display the aggregated measures based on the formula specified. DC on new column check use logical columns and click on exp. Builder. In the left column select functions and then time series then select TO DATE. Select metric from logical tables (revenue) and as level go to time dimension and select year(YTD) and OK.
YTD- year to date – Displays aggregated values that is with respect to month since it is YTD. Similarly for QTD and MTD.
Ex: sales: 100,200,300 à YTD Sales: 100,300,600

Nested aggregation using time series functions

Hi All,
I have a requirement where i need to find the growth using below formula
(A-B)/B
A=PERIODROLLING(x,-3,0)
B=PERIODROLLING(AGO(x,QUARTER,1),-3,0)
where x is a measure
I see that OBIEE doesn't support nested aggregates on time series function is there any other way this can be achieved
Thanks in advance,
KSS

Comparing AGO vs TODATE - few time-series questions

Hi All,
I just thought that someone might actually shed some light on the following situation.
I'm using AGO function for reporting CY, PY, PY-1 - etc.
So, AGO is essentially showing the value (or aggregated value) of the metrics at the same time period - and I usually use year, not months in the function.
Now, my understanding is that when I have CYTD and PYTD - I must use TODATE function. Please correct me if I'm wrong. Like if I need to show % variance over different times periods (Previous year to Current Year) and the current year data MUST be compared to the same data in the previous year. For example, if we are in January of current year, the comparison must be between Oct-Jan of current year to Oct-Jan of previous year, not the full previous year.
Here, I should probably use months' level in this situation, correct? Please correct me if I'm wrong.
Is TODATE getting a current system time and date? Or Do I need to go about creating a dynamic variable Current Month?

This can be using Msum function in answers. Use the following formula, here dollars is my metric. Change the formula based on your metric.
Msum("Sales Measures".Dollars ,2) - "Sales Measures".Dollars
the report will be cached and better performed compared with time series. check ti

Time series and Order series questions

Hi Guys - Need some help in understanding/Visualizing some basic APO concepts. I do not want to move further without understanding these concepts completely. I did read sap help and couple of apo books but none gave me a complete understanding of this very basic concept.
1. Data is stored in livecache in 3 different ways. time series, order series and atp time series. for now I am concentrating on just time series and order series. Can some one help me understand with an example how data is stored in time series and how it is stored in order series? I read that data which is not order related is called time series data and which is order related is called order series data.
My query is even in DP time series data, data is stored with respect to product and location that is transferred to snp. In SNP too data is processed with respect to product and location. so what is the difference in time series data and order series data?
2. what are time series key figures and what are order series key figures? I read safety stock for example is a time series keyfigure. why is it not a order series key figure? what makes a keyfigure time series or order series? can some one xplain this in detail with an example or numbers?
3. there is a stock category group in snp tab of location master LOC3. Stock category should be product related right? how is this related to location and what does this field mean in location master
Thanks a lot for your help in advance. Please let me know if I am not clear in any of the questions.

Hi,
Time series: Data is stored in buckets with no reference to orders.( If you place the mouse on time series data and right click for
                     display details , you will not find any information.
                      Suitable for tactical planing and aggregated planning. Usually in demand planning.
Pre requisite: 1. You need to create time series objects for the planning area.
                       2. When creating planning area you should not make any entries for the Key figure in the field Info Cube, category
                           and category group.
                       3. When creating planning area any entry you made in the field Key figure semantics with prefixed with TS.
                           (Optional entry)
Order series: Data is stored in buckets with reference to orders.( If you place the cursor on the order series data and right click
                      the mouse for display details , you will find information of order details.)
                     Useful for operative planning.
                     *You will have real time integration with R3.
Pre requisite: 1. You need to create time series objects for the planning area.( though you are creating Order series)
                      2.When creating a planning area specify a category or category group or enter a key figure semantics with prefix
                        LC.
                     3. When creating planning area you should not make an entry for the key figure in the field Info cube.

Time Balance and Time series in ASO

We are building an ASO application and we need Time balance and dynamic time series functionality.
If I go and use the TB functionality in ASO, my Time dimension has to be stored and I cannot put mdx formulas on my members (YTD,QTD,MTD)
I see various threads here and the recommendation is to have a new dimension to view the time series members (gary's blog...tnx for him)
However we cannot afford to have a separate dimension. The time series should be under Time.
How can we go with this?
Please help me with your suggestions/ideas. Thanks for your time.
TIA

Any ideas guys?
John, can you please shed some light on this.

KPI's & Dynamic Time Series

Hi All,This just won't go away!We have a KPI ("EBITDAR"%"Total Income";) which is in the Measure's Dimension (Dense). This is tagged as Dynamic, but not 2-Pass.This gives correct Act-v-Bud (Scenario Dim - Sparse) Variance, but the Aggregated Time and Dynamic Time Series (Time Dim - Dense) are calculating wrong. They are calculating a average of the averages and not an average of the totals.When I use 2 Pass the Aggregated time & DTS are correct, but the Act-v-Bud figures go completely wrong.Is there any way of getting around this?Thanks in advanceMark

Hi,Did you get any response to this? If so, can you please share.Thanks!

All input time series to which you can distribute are fixed

Hi Experts,
I ran one macro in the background. Usually it runs without any different message but this time I got following message
"All input time series to which you can distribute are fixed". Macro has executed successfully & data is also correct but it has taken lots of time to finish. When I checked I got the above message.
Can anyone help out to find the exact meaning of this message?
When I digging around the message I got the following explinantion but didn't get the meaning.
Diagnosis
All aggregrated time series objects of an aggregate time series are fixed. As such, a change to the characteristic value at aggregate level cannot be disaggregated on any of the aggregated time series objects.
Procedure
Remove at least one of the fixings of the aggregated time series objects.
Please help me to find the solution to avoid the delay in job.
Regards
Sujay

Hi Sujay,
I think you have some hierarchy in DP .Ex.one product @ diff locations and you have fixed the values of the key fig say Sales Demand at all locations and there you are trying to change some value at product level which due to fixing is not getting distributed/disaggregated on low levels of locations and hence you are getting this message.
Please refer SAP Note 609074 & 687074 which will be very helpful to you.

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
