Creating Trendline of 50 Period Moving Average

HI, im trying to plot my graph in LabView and trying to do create a treadline of 50 period moving average like in excel.
is it possible for me to do it in LabView?
i have tried General Polynomial Fit VI and some other VIs in Fittings but cant get anything close to the way i want
any ideas? anyone?
Solved!
Go to Solution.

Charlie, There's a better VI called "Mean PtByPt". Look in the palette "Signal Processing >> Point by Point >> Prob & Stat >> Mean". One added benefit: this VI gives valid data for the first 50 points, even though the mean is not "fully developed" or "stabilized" during the first iterations. (Also, keep in mind that "Delete from Array" and "Build Array" primitives make a call to the memory manager, meaning memory copies for large arrays and fast loop rates will result in a CPU bottleneck. Using circular buffers is one way to mitigate this limitation.)
64864050, try adapting this code to fit your needs:
a.lia-user-name-link[href="/t5/user/viewprofilepage/user-id/88938"] {color: black;} a.lia-user-name-link[href="/t5/user/viewprofilepage/user-id/88938"]:after {content: '';} .jrd-sig {height: 80px; overflow: visible;} .jrd-sig-deploy {float:left; opacity:0.2;} .jrd-sig-img {float:right; opacity:0.2;} .jrd-sig-img:hover {opacity:0.8;} .jrd-sig-deploy:hover {opacity:0.8;}

Material with moving average price ,while posting grn act as standard price

hi gurus
i have a material with a moving average price , according to moving average price during grn posting no price difference account should be created at any circumstance , but while i posted grn , i am getting stock account - wip 14407.98 , GRIR - DM 16800 -
Price difference matl trns - 2392.02 WHY THESE PRICE DIFFERENCE CREATED i have maintained only moving average price in accounting view
regards
Leo

hi
In SAP we have two price control moving average price and standard price
In MMR if u using Moving average Price if any difference in price it will post it to stock account
but in case of standard price it post it o PRD account (Price diff Account)

SSRS 2008 Column Chart with Calculated Series (moving average) "formula error - there are not enough data points for the period" error

I have a simple column chart grouping on 1 value on the category axis. For simplicity's sake, we are plotting $ amounts grouping by Month on the category axis. I right click on the data series and choose "Add calculated series...". I choose moving average. I want to move the average over at least 2 periods.
When I run the report, I get the error "Formula error - there are not enough data points for the period". The way the report is, I never have a guaranteed number of categories (there could be one or there could be 5). When there is 2 or more, the chart renders fine, however, when there is only 1 value, instead of suppressing the moving average line, I get that error and the chart shows nothing.
I don't think this is entirely acceptable for our end users. At a minimum, I would think the moving average line would be suppressed instead of hiding the entire chart. Does anyone know of any workarounds or do I have to enter another ms. connect bug/design consideration.
Thank you,
Dan

I was having the same error while trying to plot a moving average across 7 days. The work around I found was rather simple.
If you right click your report in the solution explorer and select "View Code" it will give you the underlying XML of the report. Find the entry for the value of your calculated series and enter a formula to dynamically create your periods.
<ChartFormulaParameter Name="Period">
<Value>=IIf(Count(Fields!Calls.Value) >= 7 ,7, (Count(Fields!Calls.Value)))</Value>
</ChartFormulaParameter>
What I'm doing here is getting the row count of records returned in the chart. If the returned rows are greater than or equal to 7 (The amount of days I want the average) it will set the points to 7. If not, it will set the number to the amount of returned rows. So far this has worked great. I'm probably going to add more code to handle no records returned although in my case that shouldn't happen but, you never know.
A side note:
If you open the calculated series properties in the designer, you will notice the number of periods is set to "0". If you change this it will overwrite your custom formula in the XML.

Numbers 3.1 restricting the period for moving average trend lines

Numbers 3.1 is restricting the period I can specify for a moving average trend line for a scatter plot series. The max is 6. This limitation was not present in the previous version of Numbers.
Charts imported from the previous version retain larger periods, but there is no way I can see to specify periods >6 for any new series. Is there a way to allow a period >6? That is clearly necessary for many applications.
Thanks.

Hi Bill,
Numbers 3.1
If you want a 14 day moving average over the prior 14 days, the formula in C10 is
=AVERAGE(B2:B15) (and Fill Down)
The formula will eventually run out of cells. Hence the red error triangles.
Plotting columns A, B and C:
X axis is Day (column A)
Blue circles and blue line are Actual Y (column B and as expected, they jump around).
Black circles and black line are calculated moving averages on a 14 day period (column C)
Red line is Numbers Trendline (Moving Average, Period 6). How it predicts into the future (Moving Average over 6 days) I have no idea.
I would more trust a calculated moving average, because I know what it is calculating.
Regards,
Ian.

How do I create a SCOM 2012 MP calling PowerShell to calculate a moving average of an event log event count?

I'm tasked to create a SCOM Monitor MP that needs to be deployed on different servers where it needs to count events in the eventlog and trigger an alert.
Before it is suggested that counting an absolute arithmetic difference is enough and offering links to such solutions, there is a "gotcha!" :
There might be one server, Server A, that gets, say, 1000 events per hour, an increase of 100+ should trigger the alert.
On Server B, only gets 100 events per hour, and an increase of 10+ should also trigger the alert.
Therefore: You *can't* use an absolute diference, but *must* use a percentage difference.
It gets more challenging as there is another "gotcha":
Actually what should trigger the alert is a rate increase of events that falls outside of two Standard Deviations of a Moving Average. The best example is the stock market: Your stock price moves up and down daily, but also steadily moves up due to
inflation over the years. You want a monitor that will alert you when the stock price goes above or below two standard deviations from the *moving average*.
I know how to call a PowerShell script from a SCOM Monitor, but I don't know how to get SCOM and PowerShell to "remember" prevous sampling's counts, because Monitors are state-less (e.g. "memoryless") .
Since SCOM, I'm told, can monitor any process state over time, I'm surprised that I don't see any support for statistical time-series analysis .
Any help would be appreciated.

Hi,
beyond advanced topic! That's what I like.
First, very good description, these are almost functional specifications!
I would also chose PowerShell.
Some time ago we did a similar situation - where
it was necessary to take into account the previous
situation|state.
We resolve this in a way that the states|values was
stored in the dedicated text file. So, at each new interval we collect new samples, read previous samples, calculate required values, stored this new calculated values, if required create property bag and trigger alert.
This is of course high level view. But in general the entire process is done in PS script.
Recently, I found that
the xml files and PS scripts bring
a lot of flexibility. Especially in building custom
diagnostics.
And there is no need to care about distribution of this files,
they may be included in the MP.
So SCOM infrastructure take care of this.
One piece of advice: First decide
whether you need only alert
or you want to steer|change health. The first case
is simpler - you need rule. The second is more complex - you need monitor!
But of course the main part is PS script.
Regards,
Ivan

Creating 6 month moving average key figure?

Hi-
I have a power user who needs to generate a "complaint rate". He needs to be able to divide the number of service notifications received in a month by a 6 month moving average of units shipped. In this same query he needs to show the complaint rate for the past 6 months. I am not a query writer...I only know the backend. But I am at a loss of how to select 6 months of data upon a load to calculate the 6 month moving average of units shipped. Any suggestions/ideas would be greatly appreciated. (Or is this a calculation that can be created in the query?)
Thanks!
-Jenn

Hi
I think this can be done in the Starting Routine of
the Upd rules.
If you are using ODS it will be easier.
for each day you need an avg of the past 6 months, so when ever you load a record you can go to the ODS it resides in via SQL and calculate the 6 months trailing avg.
to initialize the data you run a repair full load that will make the calculation.

Exponential Moving Average - EMA - in PowerPivot

Hello All
We´re having a challenge trying to put the [20] (trading days) Exponential Moving Average (EMA) in our data model in PowerPivot.
Here is the EMA formula and sample spreadsheet:
http://stockcharts.com/school/doku.php?id=chart_school:technical_indicators:moving_averages
Pasted the formula here for convenience:
SMA (simple moving average): [10] period sum / [10]
Multiplier: 2 / ([Time period] + 1) )
EMA: {Close - EMA(previous day)} x multiplier + EMA(previous day).
Sample spreadsheet
http://stockcharts.com/school/data/media/chart_school/technical_indicators_and_overlays/moving_averages/cs-movavg.xls
In our model the fact table have these columns:
Symbol Date Open High Low Close Volume
And in the Calendar table we´ve identified the trading days (Calendar[TradingDayNumber]) as 1 so we can count them back.
We want the EMA calculated field in a pivot table like this
Filter context: a date selected on Calendar[FullDate]
Row context: FactTable[Symbol]
Values: FactTable[Close]
FactTable[EMA 20D] >> Missing
So far we got these calculated fields:
Period
=20
Ema Multiplier
=2 / ([Period] + 1)
Average 20D CLOSE
=IF([Sum of CLOSE]=BLANK(),BLANK(),(CALCULATE(AVERAGE(FactTable[CLOSE]),FILTER(ALL(Calendar),Calendar[TradingDayNumber]<=MAX(Calendar[TradingDayNumber]) && Calendar[TradingDayNumber]>MAX(Calendar[TradingDayNumber])-[Period]))))
But it looks like the EMA formula contains a self reference from previous values, and it also starts from a SMA (Average 20D CLOSE) value.
How can we do it?
Thanks in advance. I highly appreciate your support.

Nico,
Is this still an issue?

Updation of Moving Average Price

Dear Experts,
My MM period is open for 2 months (i.e for July and August Now) . One of our raw material is Limestone.
From July 1st there were several Receipts and Issues of limestone in SAP.
In August 9th our survey team found that in our stock we have 25000 TON limestone excess. (Due to Callibiration error)
i.e If the current stock in system was 10000 TON the real Physical stock in storage was 10000 + 25000 TON.
We have created a Free of Cost PO for 25000 TON to account the excess quantity of Limestone in Stock.
MIGO Goods Receipt for the Free of Cost PO was done on 31.07.2011.
Because of the extra 25000 TON Free of Cost Limestone Receipt the Moving Average Price of the Material got Updated. (But only from 09-August-2011 not from 31-July-2011)
I want system to calculate the new moving average price and update all the documents posted from 31-July-2011. MY MM period is not closed.
Is it possible to do so and how. Please Help.
Thanks

Hi
The physical inventory is carried out on the basis of stock management units.A stock management unit is a non-divisible part of a stock of materials for which a seperate book inventory exists.A stock management unit is uniquely defined by
Material
Plant,storage location
Stock type
Batch
Special Stock
Each stock management unit of a material is counted seperately,and the inventory diffreneces are posted per stock management unit.
The physical inventory process comprises three phases
1)Creation of physical inventory documents(MI01)
2)Entry of Count(MI04)
3)Posting the difference(MI07)
1)In the first phase ,you create the physical inventory documents.SAP systems provide several procedures for mass-generation of PI documents.After selecting the stocks to be counted and creating the PI documents,you print out the documents in order to start the counting process.A physical inventory document cotains data that include
>The plant and storage location in which the count has to take place
>The date on which the count has to take place
>The materials to be counted
>the stock types to be counted
>The status of the item
>The status of the PI document
When creating a PI document,you can specify a physical inventory nuber in the document header.This physical inventory number facilitates selection of the PI documents to be processed during entry of the count data,posting the diffrences, and in evaluations.
2)Entering the physical inventory count:For the physical inventory count,you must print out the PI document and forward it to persons responsible for the count.You can enter the stock figures in the system with and without reference to a PI document.When entering the physical inventory count,you can enter a percentage variance of the count quantity from the book inventory,above which the system issues a warning message.
3)You can post the inventory diffrences either via list of differences or via seperate transactions.When an inventory difference is posted,the system creates a material document and corrects the stock figures,and an accounting document recording the necessary accounting movements.
Hope this will be helpful for you.

Problem with moving average

I have to create a report which displays rolling average of revenue.
The report contains two columns week and avg revenue. I have to display only ten weeks from the current week.
For each week the revenue should be calculated as follows;
weeks     actual revenue     Avg revenue
1     10          10
2     20          (10+20)/2
3     30          (10+20+30)/3
4     40          (10+20+30+40)/4
5     50          (20+30+40+50)/4
6     60          (30+40+50+60)/4
(current week-10 weeks)
current week
I have used Mavg(actual revenue, 4) to calculate avg revenue.
I am getting the correct values. However if I apply a filter say weeks between current week and (current week-10 weeks), I am facing a problem.
My (current week-10 weeks) is now showing avg revenue as 10 which is my actual revenue amount.
But i would like to show the revnue amount as an avgerage of (current week-10 weeks) and previous three weeks.
The filter to limit the number of weeks is applied before calculating the moving average. Is there anyway to calculate the moving average first and then apply the week filter to report.
Pls help me solving this.
Thanks

Do this:
Have the measure as :
case when Periods."Weekdate" > TIMESTAMPADD(SQL_TSI_WEEK, -10 , CURRENT_DATE) then MAVG ("Sales Measures".Units, 4) else 999999999 end
And then apply filter on the above measure column as :
Case when Periods.Weekdate > TIMESTAM... ' is not equal to / is not in 999999999
Let us know how it goes.
PS : To prevent runaway query, you may want filter it further by Periods."Weekdate" > TIMESTAMPADD(SQL_TSI_WEEK, -15 , CURRENT_DATE)

Does moving average price work with multiple valuations?

Dear All,
I have activated multiple valuations: Legal, group and profit center.
I have activated ML/Actual costing for this multiple valuations too.
Now I have 3 price fields in material master.
Could I use moving average price for some materials types in multiple valuations?
Thank you,
With best regards,
Kamila.

Hi Kamila,
yes, ML is always activated for all materials in a plant. To use MAP you have to set the price determination of a material to '2':
This is the F1 help of the field price determination:
Material Price Determination: Control
Specifies how the material price determination should procede.
You have the following options:
With price control V in activity-based material price determination (indicator2 in the material master), the moving average price is calculated. With price control S, the material is valuated with the standard price and the moving average price is calculated for information purposes.
In single-/multi-level material price determination(indicator 3 in the material master), the valuation price (standard price) remains unchanged and a periodic unit price is calculated for the closed period.
This option is only for materials with price control indicator S,and is only recommended if in addition to multiple currencies and/or valuations, you use single-/multi-level material price determination.
In single-/multi-level material price determination, a periodic unit price is updated for information, but it can only be used for material valuation in the closed period.
Dependencies
The indicator is only of use if the material ledger is active.
Upon activating a valuation area for the Material Ledger in Customizing, you can enter what type of material price determination will be proposed when creating a material in that valuation area. This proposal will be ignored at production startup: the system automatically sets the indicator to 2 in the material master for all materials present.
If you want to change the indicator for a particular material later, choose Accounting -> Controlling -> Actual Costing/Material Ledger -> Environment -> Change Material Price Determination.
best regards,
Udo

Changing of Inventory Valuation: Standard to Moving Average Price

I work at a service-based company and have also been asked to research the impact involved with switching our inventory from standard price to moving average price.
Scenario: Change material type TRAD (trading goods) from standard price to MAP.
Process: Change settings in SPRO at the level of u201CDefine Attributes of Material Typesu201D. Currently, this is set for u201CStandard priceu201D with the indicator u201CPrice ctrl mandatoryu201D set. Upon change to u201CMoving average price/periodic unit priceu201D, Iu2019m thinking I need to de-activate the u201CPrice ctrl mandatoryu201D field so any current materials with an u201CSu201D in the Price control field on the Material Master Accounting 1 tab can be changed to u201CVu201D. Is this correct? Also, is there a program that already exists to mass update the Price control field on the Material Master? If not, I was looking to create a CATT for this changeu2026.any other ideas? In some of the forum posts it was mentioned to use t-code MR21 however, even with the u201CPrice ctrl mandatoryu201D field de-activated, the Price control column is grayed out.
It was mentioned in a previous post that all open documents (PO to IR) need to be completed before changing the price control setting, at what point does this stop the process? Does SAP generate a system error message?
Also, any suggestions as to when this price switch is best to take place like after inventory?
Are the above mentioned areas the only areas I should be concerned about or am I missing some areas that should be addressed?
P.S. We do not use have our ML (material ledger) activated or use split valuation.
Thanks~
Dawn

Hi,
If you want to change material from standard to moving average price, Follow the below process
1)first the material quantity and value should be zero
2)if you want to keep value and quantity and want to change price control in future you have to create new material with price control "V' and lock the previous material for posting.

Moving Average Price - RM

Hi,
For the client, to perform actual costing we have enabled
ML.
Price Control :RM - V & SFG/FG - S,
We have completed the product cost planning, performed GRR .
For the mentioned above scenerio, request to answer the
following queries:
a) How to avoid the updation of standard price for RM?,
b) While performing GRR,
Ex : Last Moving average price : 0.55 Paise / KG,
PO price : 0.90 paise / kg,
system passes the following FI entries:
110001     Inventory -RM     6.600,00
210002     GRIR     10.800,00-
410061     Price Diff-RM-PRD     4.200,00
- can any one explain the same how to rectify the same to get the complete amount in Inventory than in price difference?
Rgds
SMK

Hi,
Your scenario is like this:
RM Price Control - 'V'
Price Determination - '2' (Transaction Based Settlement).
SFG / FG - Price Control - 'S'
Price Determination - '3' (Periodic Price Unit).
for items with price control 'V' and Price Detrmination '2' the system would create 2 accounitng documents together with the GR.
1. The first accounitng document is what you have written.
2. The second accounting doucment will settle the price difference posted in the first document to the mateiral. Thereby ensureing that material is valued with moving average price.
The price determination is '2' which means Transaction based settlement so the system identifies the difference, posts it and also settle it to the material simeltenaously.
You can confirm that the valuatioin is correct by checking transaction CKM3.
Hope this helps you.
Thanks & Regards,

How to get moving average price in 0ic_c03 with back dating

Hi all,
The stock overview report in 0IC_C03 gives stock values based on Purchase value where as i need to calculate the stock value based on Moving average price, (so that it tallies with R/3 std report MB52), also need to get the stock value for backdating also i.e like MB5B standard report in R/3.

Hi,
The stock overview report in 0IC_C03 gives stock values based on Purchase value where as i need to calculate the stock value based on Moving average price, (so that it tallies with R/3 std report MB52)
--> Need to enhance 0IC_C03 for moving average price and need to multiple Quantity with price to get value. You can do this at extraction level(Transformation / update rules) or Query level.
also need to get the stock value for backdating also i.e like MB5B standard report in R/3.
Or Maintain material price as Material attribute and create a multiprovider on 0IC_C03 and Material and calculate value at query level. In this approach value getting derived based on available price only(means historic values may change if price changing over period of time).

Shifting from Moving average to standard price

Hi all
Presently we are following for all our Inhouse produced materials with Moving average price,we want to change all the materials to Standard price,is it possible to change & if in case if stock is there we will not be able to change,Shall we have to create New material codes with price control S.
whats the best solution
Thanks
Sandeep patil.

Dear,
ML is meterial ledger.
It is used in following cases.
- You have mutliple currencies and to see the stock in differnt currancies.
- You want to see the variances to be carried to different levels of BOM and see the periodic price of the product even though the price control is S.
Hence system will count all the variances and during ML closing steps calculate the variances and send to the higher level of BOM after chaning the periodic price of that raw materil. Hence at higest product level you will come to know exact production cost as well as level by level subassembly cost.
With this cost you can revaluate the material so that the S price will change to this periodic price.

Standarad price and moving average price

What is the diff between Standarad price and moving average price ???

Price Control V or S in material type
When is it useful to use the price control V or S in Material Master ?
Do I have to follow the SAP standard setting in the material type for the following material types:
- ROH(Raw materials) -> moving average price
- HALB(Semifinished products) -> standard price
- FERT(Finished products) -> standard price
In which case and why is useful to change these standard setting in material type?
What is difference between standard price and moving average price?
When and how to use it?
Standard price are used for products that do not fluctuated frequently. It is usually used for finished or semi finished products.
Moving average price are used mainly for raw materials that are purchased externally. The advantage of using moving average price for your raw materials is that your inventory costs will always reflect the current market cost.
SAP strongly recommends that you do not select price control V for semi-finished products and finished products, because doing so will very easily cause the calculation of unrealistic valuation prices. SAP recommends:
Price control V for raw materials and trading goods; price control S for semi-finished products and products.
If you nevertheless select price control V, take care in the following situations:
1. Unrealistic prices occur if materials are produced and also retire during one period (that is, the inventory at the end of the period is smaller than the total of aquisitions from production orders) and if, in addition, several production orders belonging to a material were finished in this period, and the production order settlement calculates variances at the end of the period. Every single production order carries out an inventory coverage check and may therefore cause the moving average price to be changed. However, the individual production orders do not check whether the inventory available at the end of the period has already been debited by another production order.
Example: on 20 workdays in the period, 1 piece of material xyz was produced for each day and delivered to the warehouse at a price of USD 1000. At the end of the period there is 1 piece at the warehouse. Since an activity price of a participating cost center was higher than planned , every single production order calculates cost of goods manufactured of USD 1100 during the settlement. Every single one carries out a inventory coverage check and finds out that the variance can be posted completely to the inventory. That is, the ending inventory of one piece is debited with USD 20 x 100 and it consequently receives a price of USD 3000.
1. A settlement is carried out although not all costs have yet been posted to the order. This can even result in a price of 0 for the delivered product.
2. No period check of the costs is carried out on the order, that is, costs from previous periods may be settled.
3. Settling orders is already possible in the 'Delivery completed' status.
Solution: Standard price for products together with possible manual price changes.
If you are required to valuate semi-finished and finished products with actual prices that correspond to the costs of the actual production, SAP recommends you use the function of the material ledger for this. Here, a periodic actual price is created that is calculated on a much more reliable basis than the moving average price. A so-called price limiter quantity is used which makes sure that in the above example price differences are proportionally taken into account (95% of the total price differences) when valuating the 19 pieces withdrawn from material xyz which results in a periodic actual price of 1100 USD. In addition, it is possible as of Release 4.5 to even take into account the variances of the actual prices of the raw materials in the valuation of the semi-finished and finished products that are manufactured from it.
If we select std price for any type of material or mav and then make po, it will pick from material master or what?
The Purchase Info Record have the FIRST priority. When no po info record is found, the Purchase Order will pick the user LAST enter price. The PO module do not pick up any price from material master.

Ashok
