Extract Range of Data / Waveform Zoom

I have an NRF recording file with several channels. What I need to do is visualize the data and then extract a small part of the waveforms into a TDM or Matlab file. I actually managed to get all this done in DIAdem, but in a most cumbersome way:
1) Import NRF file into the Data Portal using the DataPlugin
2) Convert all signal channels to Waveform channels (using the function in the ANALYSIS module)
3) Display the waveforms in the VIEW module
4) Zoom downto the sample level in order to figure out where to start and stop the extraction
5) Write down the start/stop x-coordinates (i.e. XStart, XEnd)
6) Switch to the ANALYSIS module and generate a numeric channel with "First value" = Xstart, "Last value" = XEnd and "No. of values" = (XEnd - XStart)/SampleTime
7) Use "Linear Mapping..." to extract the desired data
8) Convert the extracted data to a waveform channel
9) Export data to desired file format
Now for my questions:
* I'm using DIAdem 10.0 (Base Edition) and would like to know if there is not a much simpler way of getting this job done, i.e. selecting two points on a waveform, click one button and get the data between those points as a new waveform in the Data Portal (ideally for several waveforms in parallel)
* Isn't there any way of zooming out one step in the waveform viewer? I only found zoom on/off which is a rather crude way for navigating)
* Are there any news regarding the topic in the thread "Selecting a range of data from a file" (last posts date back to February 2005)
Any help is greatly appreciated. Thanks

Hi,
* How can I run a VBS script with my Base Edition: the whole Script feature is disabled, but I was under the impression that I can run scripts (just not edit/debug)
... with an Link on the Desktop from your DIAdem. In Properties of this Link, you can set the Parameter:
"DIAdem.exe" "/cScriptStart('MyScript')"
... with the start Script in every Module in DIAdem. Have a look at the Screenshot.
* Isn't there any way of zooming out one step in the waveform viewer? I only found zoom on/off which is a rather crude way for navigating
... I´m sorry Zoom out isn´t anywhere! But you can make it like the second picture. With the upper Graph, you an control what you see in the second Graph. Zoom In/Out, no Problem
* Also how can I precisely (down to the sample level) place the two band cursors? Using the different zoom modes I manage to do it for one of the two cursors, but not the other one.
Sorry, I don´t understand your question! Perhaps you can precisely set you Cursor with the Coordinat Window? Have a look!
Best regards
Alex

How to extract all the dates given in a date Range.

Hi,
I would like to extract all the date given in a date range select option field, Kindly let me know how is
it possible in most optimized way,
Regrd
Ali

Hi,
You can code like below.. Declare the Ranages and use those ranges to append the data.
Ranges : R_date for Table-date.
R_date-Sign = I
R_date-Option = BT
use the Select statment SELECT * FROM TABLE INTO ITAB WHERE DATE IN S_DATE.
use the append statmenets to APPEND R_Ranges.

Using a range of dates for Key Date

In a HR Bi data warehouse, we have a position-to-position hierarchy, where each of the nodes are time dependent. So, it shows for each node, valid from and valid to dates, and all the employees who are reporting to that position. This hierarchy is built on the infoobject 0HRPOSITION, which is maintained in R/3 and extracted to BI.
Let us take an example: Position 1000 is valid from 1-1-2006 to 6-30-2006 Employees reporting to this position are A,B,C,D
Position 1000 is valid from 7-1-2006 to 12-31-9999 Employees reporting to this position are A,E,F,G
When a user chooses the position 1000, and date range 1-1-2006 to 12-31-2006, it show the complete list of employees as
A,B,C,D,E,F,G.
Because the Keydate can only be a single value, and it is automatically taking today's date, and pulling the nodes based on that.
I have created a hierarchy node variable on the 0HRPOSITION infoObject, and entered the value 1000, with no value for the keydate.
The system is simply showing employees, A,E,F and G. That is my problem
My requirement is this: I like to be able to give a date range, (for the hierarchy) say from 1-1-2006 to 12/31/2006 and get the complete list of Employees, which is A,B,C,D,E,F,G.
Is this possible? Can I change the way this hierarchy is defined so that I can pull the possible values for a range?

Thank you Ajay.
After some thinking, I have realized that these options will not work.
We have a position-to-position hierarchy that shows who reports to who in the organization. This hierarchy is built on the Infoobject 0HRPOSITION. Each node in this hierarchy has is time-dependent. Note that, the entire hierarchy is not timedependent. Only the individual position nodes are time-dependent.
This 0HRPOSITION infoobject exists in the Heacount cube as one of the characteristics. Here is my requirement.
1. I want to show in a report, all the employees (directly or indirectly) reporting to a manager for a period of say, 1 year?
I know that I can specify a key date for the hierarchy 0HRPOSITION, then the report will show all the employees (direct and indirect) reporting to a position say 6/30/2008. I don't want this for a specific date, I want to get ALL the employees (direct and indirect) reporting to a position in a range of dates( say 1 year)
Does that make sense? How do we achieve this goal?

How to break range of dates into different months in mm/yyyy format

See the following eg:
MaterialNo         Validfrom         ValidTo            RecordNo                    Value
A100                01.01.2007        13.05.2007       1000                           1150/-
                         14.05.2007       24.08.2007        1001                           1550/-
Now I want to break these dates into mm/yyyy format based on a condition. If the date(day) 15th lies in the range of dates
then it should pick that Value.
The output should be in this format.

Hi Shiva,
In your Report Program, you can define the field of type sy-datum. And then fill the fields with the date. And then you can extract the rest of it manually by this small and simple lines of code. Once you have the date extracting logic then you can output the date in any manner according to your wish.
data : lv_date TYPE sy-datum.
data : lv_month TYPE c LENGTH 2.
data : lv_year TYPE c LENGTH 4.
data : lv_month_year TYPE c LENGTH 6.
lv_date = sy-datum.
lv_month = lv_date+4(2).
lv_year = lv_date+0(4).
CONCATENATE lv_month lv_year INTO lv_month_year.
Hope this helps.
Thanks,
Samantak.

Best Option for extracting B2 cluster data

Hello Experts,
I need your expert opinions for one of my extraction needs. The need is to extract data from B2 cluster. My doubts are on the best possible way for implementing this generic extractor. Below are my thoughts:
1. Build a generic extractor and write a user exit that calls FM 'HR_FORMS_TIM_GET_B2_RESULTS'. Somehow pass the DATE ranges and PERNR as parameters to the FM and later build my extraction logic. But, what would really be the source for this generic extractor. An extract structure is just not sufficient.
2. Other approach is to use FM based extractor (using copy of RSAX_BIW_GET_DATA_SIMPLE) and have copy of 'PTDW_QUOT' extract structure as E_T_DATA parameter. This can get complex.
Please share any thoughts on the above approaches. Looking forward to the best possible way of doing this...
Thanks.

Hi Mann
I am also tryiing to extract B2 cluster data to BI. I would really appreciate any info/advice you could share on your resolution. Is it working well?
Thanks very much

Yes, windows to Mac too.
iTunes: How to move [or copy] your music [library] to a new computer [or another drive] - http://support.apple.com/kb/HT4527
Quick answer if you use iTunes' default preferences settings: Copy the entire iTunes folder (and in doing so all its subfolders and files) intact to the other drive. Open iTunes and immediately hold down the Option (alt) key (shift on Windows), then guide it to the new location of the library.

Can you lock the Waveform Zoom to a specific time?

I edit audiobooks. Mono voice. No multi-track, just one channel of voice. When I select a zoom "width", shall I say, of the waveform - say I'm looking at just :15 seconds of waveform of 25:00 minutes of total audio. In other words, I'm zoomed in a lot. Audition frequently re-sizes the zoom, randomly and at will. (It's will, not mine!)
Sometimes it will zoom itself all the way in. Sometimes it might zoom out to see 3:00 of the 25:00. It just does it when it wants to.
Is there a way I can lock the waveform zoom to a specific "width" or time span?
What is triggering the software to do this?
I'm using the Mac version with a bluetooth Mac Mighty Mouse.
Thank You

You can prevent the zoom level from changing by setting the "Zoom Sensitivity" to 0% in Audition's Preferences on the General tab. For me that means that the mouse scroll wheel has no effect on the zoom level.
Some of the buttons and keys (=/-) for zooming in and out will have no effect. What will happen if you try to zoom in is the waveform will be scrolled left/right, but not zoomed in/out, so the CTI is centered in the display.

How to load a range of data in Diadem?

Hello; I have a set of Access DB containing analytic data of 5 jears. How can I import a range of data (eg. all year 2003 data)in Diadem for analysis?
Thank's

Thank's,
but I couldn't choose explizit the time channel. Also I couldn't set a command like 'between 1.1.2003 and 31.12.2003'. Attached is an exemple of the dataset. The time channel is '50_DAT'.
It would be nice to get an answer.

How to find a specific day in a range of dates

Hi !
Can someone help me with this
I would like to find if there is a Saturday in a range of dates:
ex: OpenDate:2012-01-19 to CurrentDate, should return 2012-01-21
      OpenDate 2012-01-23 to CurrentDate, should return null field
Thank you

Hi Diane,
You can use this formula to find a Saturday in a date range:
numbervar days := datediff("d",{Date_Field}, currentdate)+1;
numbervar x;
datevar array dates;
redim dates[days];
datevar sat;
for x := 1 to days do
    dates[x] := {Date_Field}+(x-1);
    if weekday(dates[x]) = 7 then
    datevar sat := dates[x];
sat;
Hope this helps!

Extract work order data from r/3 system in flat file(csv)and export to BI

Hi,
I am new in interface.
I need to extract data regarding actual cost and quantities of work assigned to Service Providers from SAP system and send it to BI for reporting purposes.
This interface will extract Master data as well as transactional data. Extraction of Master data will be a full extract and that of transactional data will be Delta Extraction.
Custom development will extract the data from different fields and will export it to flat files (CSV format). This program will amalgamate all the flat files created into one big file and export it to BI system.
Export of data to BI system will be done by schedule program Control M, which will export the data from SAP system to BI system in batches. Control M is expected to run daily at night.
Please provide the step-by-step proces to do this.
Thanks

How to extract the historical data from R/3

hi
I am extracting data from R/3 through LO Extraction. client asked me to enhance the data source by adding field. i have enhanced the field and wrote exit to populate the data for that field.
how to extract the historical data into BI for the enhanced field. already delta load is running in BI.
regards

Hi Satish,
As per SAP Standard also the best way is to delete whole data from the cube and then load the data from set up tables as you have enhanced the data source.
After data source enhancement it is supported to load normally because you don't get any historical data for that field.
Best way is to take down time from the users, normally we do in weekends/non-business hours.
Then fill the set-up tables; if the data is of huge volume you can adopt parallel mechanism like:
1. Load set-up tables by yearly basis as a background job.
2. Load set-up tables by yearly basis with posting periods from jan 1st to 31st dec of any year basis as a background job.
This can make your self easier and faster for load of set-up tables. After filling up set-up tables. You can unlock all users as there is no worries of postings.
Then after you can load all the data into BI first into PSA and then into Cube.
Regards,
Ravi Kanth.

How to extract 64 bit data from imaq image using IMAQ Extract VI

I have LV 8.5.1, Vision 8.5 and need to extract 64 bit data from a 64 bit image and I get the "invalid image" error while using the IMAQ Extract VI. What version of Vision do I need to allow me to do this?
Currently, the work-around I have...
1) convert the image to 32bit
2) use the ROI tools I to get the rectangle data I need
3) then go back to the original image and the convert the image to a 64 bit array
4) take the rectangle data to extract the data needed out of the 64 bit array data.
klunky but it works. I would think that the IMAQ Extract tool should allow me to extract the 64 bit data but it doesnt... forces me to 32 bit.
suggestions?

steve05ram360 wrote:
awesome, that does work.
Attached DLL slightly corrected and should be OK also "in place" when Dst is not connected like original IMAQ function. Hopefully it works properly now. By the way all IMAQ types are supported, not only U64.

How to set a date range for date field ?

Dear Experts,
Scenario:
I have a query in validating the date field in my BSP application. My application is for maintain infotype 0023 Other/Previous Employers online by employees in the company.
As per our design we are maintaining the all employment details of the employee both ( with in the current company / previous employment outside the company) in the same infotype.
Every employee will have a hiring date within the SAP HR system. We consider this date as the cutoff date between current and previous employment in our application. When the employee updating the details wia BSP page I need to check the following.
Record inside current company: Validation that, the user should only able to enter BEGIN DATE (BEGDA) greater than or equal HIRING DATE and END DATE(ENDDA) should be greater than FROM DATE (BEGDA).
Record outside current Company: Validation that, the user should only able to enter BEGIN DATE (BEGDA) less than or equal HIRING DATE and END DATE (ENDDA) should be greater than FROM DATE (BEGDA) and less than HIRING DATE.
Technical Requirement:
How to set a date range for date field, i.e. how we can limit the date range in a HTMLB date field? Can this it be achieved via standard functionality of HTMLB?
Following is the code to describe date field in my application.
    <htmlb:inputField id= "ENDDA_NEW_IN"
                      type= "date"
                doValidate= "TRUE"
                  showHelp= "TRUE"
                  disabled= "FALSE"
                     width= "183"
                     style= "cssTextAreadate"

Unable to extract Customer Master data from MDC

Hello,
We creating an MDM-XI-ERP2005 Customer scenario. We want to work with all bussiness scenarios (not customizing scenario).
First I'm trying to extract Customer Master Data from EP 2005 using MDM_CLNT_EXTR.
I have created a New Variant which properties are:

But, the display jobs shows the following error: Could not determine recipients for message type MDMRECEIPT. Job cancelled after system exception.
We need to focus the problem. We have done the following ALE configuration.

Any idea will be very helpful,
Thanks in advance
Marta.
Edited by: Marta Sánchez on Jul 9, 2008 12:34 PM

Sorry because I made a mistake in my previous message. ALE seems to be correctly configured. I'll try to update correctly my current situation:
In WE02 I can see al IDOCs that I'm trying to send to XI. All them have the IDoc Status = 3 (Data Passed to Port OK) instead of 12 Status Dispatch OK :(. So, It seems an tRFC error.
SM58 shows me more trails: "Basic type 'DEBMDM06' is unknown"
before that I have done the following steps at SAP ERP:
    1. WE21: I have created a PI7 port with 700PI70CLNT RFC.
    2. SM59: I have checked successfully 700PI70CLNT RFC connection.
    3. WE20: I have created a PI7 Partner Type LS with the following inbound and outbound parameters: DEBMDM and MDMRECEIPT.
    4. BD64: I have created a Distribution Model with DEBMDM and MDMRECEIPT message types.
and at SAP PI:
     5.IDX: Port: SAPEUS. Client: 111. RFC Destination: PI7.
     6. technical and business system for sender SAP system(System Landscape Directory)...
- Maybe some of the previous steps is not correct....
- Is RFC Destination = PI7 is correct in step #5?
- Is also necessary to configure more steps in PI system like RFC destinations or Transactional port?
- I have read that is neccessary to check that the option "transfer idoc immediately" in we20. How?
Please any idea will be very helpful.......
Thank you!
