Differential Measurements with AI-10X
Is it possible to make measurement in differential mode on FP-A10X, using two channels to achieve this (like on E series Cards)? I saw that it's possible with dualchannel modules, but I need to measure [0-40V] signals...and dual chanels module can't...
The only way to get differential measurments on non-differential FieldPoint modules is to use a single channel per module.
Note: the dual channel analog modules are not isolated channel to channel and share a common between channels so they can not be used differentially. The advantage for the dual channel modules is that you only lose 1/2 of the channels per module when performing differential measurements rather than 7/8 or 15/16 of the channels.

Differential measurements with a DAQ-500 card
I can't put the differential measurement mode in the Measurement & Automation Explorer. I'm using a DAQ-500 card of NI. Is this because my card doesn't support such measurement mode? There are no jumpers on the card for such a configuration...
Some help on this topic would be useful.Hello Nicolas,
Thank you for your question regarding a DAQ-500 card. It sounds like you're having problems getting the card to operate in differential mode. Is your device perhaps a PCMCIA DAQCard-500? If so you should be able to use four analog differential inputs. Where is the problem occurring in MAX? Can you right click on the DAQCard-500 in Traditional DAQ Devices >> properties >> AI and then go to mode and select Differential there? If the device is indeed the DAQCard-500 shown here and the problem hasn�t been solved you may want to try to reinstall the card.
Other resources can be found on the ni.com website by clicking the support tab at the top of the home page. Then search from Technical
Resources at the top of the page for your topic. I hope these resources help! Let me know if you need any other support with this issue.

Problem with Non Reference Single ended and Differential measurements
The following was misposted at the Real-Time DAQ category and should appear in this Multifunction DAQ category:
I am doing a differential measurement and then a non referenced single ended AI measurement using the same PCI 6025E card. Most of the time I get good measurements however a small percentage of the time I get very strange measurements.Make sure that you have set up each of your channels for the appropriate mode of measurement. By default, Measurement & Automation Explorer (MAX) has a property set for your card, either differential, nonreferenced singled ended, or referenced single ended. If all your channels are in one mode, then you can just left those defaults stay. Otherwise, as in your case, you would need to programmatically set each channel for the right mode.
For instance, in LabVIEW, the AI Configure.vi has an input parameter for "coupling and input config". This is an array of data that includes the measurement mode. Each element of the array corresponds to the element in the channels array, so you can configure each channel appropriately. Make sure that you have this set up in yo
ur program, and you should get the correct measurements.
Finally, double-check your physical connections to see that they match the measurement mode you chose. You can find this in the 6023E/6024E/6025E User Manual or the PCI E Series User Manual at the http://www.ni.com/manuals website.

Differential Measurement Of My UUT
Hi,
I having problem using PCI-6025E for differential measurement on my UUT (an audio product, BTL output).
I had switch to differential mode in MAX. Measurement connection positive (ACH0), negative (ACH8).
I able to get the RMS value and freq of the measurement however the waveform is not uniform (unable to get beautiful sinewave).
When I use Scope to measure the UUT output, I able to get uniform sinewave.
I also tried to replaced the DAQ board however in vain.
May I know what can be wrong in my measurement?
Thank you in advance.........
Best Regards,
NormanYou might get better answeres in the Multifunction DAQ forum . The feedback forum is for site issues. Good luck!

How to use external timebase for Two Edge Separation measurement with PCIe 6351
Hi
I am working with PCIe 6351 x series DAQ card.
counter measurements.
Here i need to measure the time/no edges between two edges. Falling to Raising of two signals.
I got the measurement with internal time base.
here i need to synchronize the measurements with external clock from the external setup.
so i need to use that external clock,timebase for the counters.
Any solution please..
Regards,
HariFirst, the VI you mention is NOT for STC timer/counters. Therefore, it won't work.
If you want to get the time interval between two edges, you want to use the Functions -> Data Acquisition -> Counter -> Count Events or Time VI. This will do the function you are looking for.

Unit of measure with language Key
Hello Guruz,
WHile creationd of purchase order, there is a check kept which compares the vendor communication language which gets updated in the Po header - Communucation tab with Db table T006A which holds the Unit of measurements with Language Key and pops up an error message.
It cheks the order unit in the PO, and the T006A whether the unit is maintained in the Language key as in the PO header - Communiction tab.
But while creating a unit of measurement in CUNI, we dont have the option to maintain the language key for the UOM.
In CUNI, it defaults the language key as EN in table T006A.
I need a prompt support from you guys on this issue. Please suggest how to go about with this?
Best Regards
Greg.Hello,
When i am trying to go for the language key in CUNI, it says that the said language is 'not available in server'. I guess it is checking whether the language patch is updated in the server.
But it doesn't sound logical to maintain all the unit of measurements in all the vendor languages. Suppose if we are having vendors with 75 communication languages and we are having 50 units os measurements, so does that mean that we have to maintain units of measurements 75 X 50 times ?
Kindly provide your inputs on the issue. We are facing lots of issues with this control kept in PO header checking for the T006A with the vendor communication language.
Regards

In the DAQmx 9.4 Readme the following is stated:
Samples Not Acquired on NI 660x or NI 6624 Devices When using pulse width, semi-period or two-edge separation buffered measurements with the NI 660x and NI 6624 on counters 0 and 1, some samples may not be acquired under certain circumstances.
Could anyone elaborate on this? I am particularly interested in knowing under what circumstances this problem arises for the 6602 PCI devices.
How should I understand 'NI 660x and NI 6624 on counters 0 and 1'. Is it only a problem on counter 0 and 1 for the 660x or does this only apply for the 6624 devices.
/molaAre there any NI Product Support Engineers out there who has an answer to this question and who are willing to share it with me?

Personal recruitment How to do new measure with function call Update IT4000
Hi out there and happy new year to forum,
i want to update to implement a recruitment measure (Transaction PB40). I did it already with batch input, but i guess it's much more comfortable to do with funtion module, bapi or calsses.
After choosing the measure, the infogroup will be processed. So i guess, i just have to use the corresponding function modules to update the infotypes in a given sequence. is this suggestion right?
What are these function modules? How to update f.e. IT4000? Does anyone has a coding snippet?
Is it HR_INFOTYPE_OPERATION?
In our Infogroup there are also customer specific infotypes f.e. 9***. Can I use the sap standard function modules for "own implemented" infotypes?
I also appreciate an abap oo pattern or any similar....
Best regards,

But I don't think that it's possible to hire an application completly with function modules (there is no PERNR in the beginning so I would keep the BIM).
The applicants already exists in system, i just want to implement a measure with exact one click!
Otherwise there is a BAPI for applicant_create.
I'm not very expierienced focussing the implementation in pa-recruiting. I'm really looking for a good documentation or anything like that f.e. sap press.

What are the alternatives to it. (I'm not looking forward to upgrade releases or using wd4a or webgui). we are on ecc 6.0 There is already a lot of z-coding in recruitment. We are also using an self implemented e-recruiting approach

Exporting set of measures with aliases into essbase cube
We were wandering if there is an easy way to import bunch of measures with aliases into Essbase cube rather then entering them one by one?
thank youSimplest way, would be to create a spreadsheet with the Measures and alias listed in column format.
You can organize them in Generation, Level or Parent-Child format.
Create a dimension load rule that maps the columns to properties in Essbase.
When you want to modify the Measures dimension layout, change the spreadsheet and rerun the load rule.

Error "CONVT_NO_NUMBER" while performing user measurement with USMM
Hi,
While running user measurement with USMM I am getting following run
time error.
To be specific - After preselections in USMM->system measurement->while
checking Green Check mark this error is screaming up.
Ae per Note - 1230640 :- You call transaction USMM and want to cancel
the user measurement using the cancel button (red 'X') on the dialog
box of the user measurement. However, the measurement continues and is
completed as if you had chosen the ok button (green check mark).
Above note is applied if the problem comes if we check red button
rather than green check mark.
Please suggest us the best way to procees.
ST22 details:-
Runtime Errors CONVT_NO_NUMBER
Exception CX_SY_CONVERSION_NO_NUMBER
Date and Time 09/16/2008 07:42:32
Short text
Unable to interpret " 1,410 " as a number.
What happened?
Error in the ABAP Application Program
The current ABAP program "RSUVM001" had to be terminated because
it has
come across a statement that unfortunately cannot be executed.
What can you do?
Note down which actions and inputs caused the error.
To process the problem further, contact you SAP system
administrator.
Using Transaction ST22 for ABAP Dump Analysis, you can look
at and manage termination messages, and you can also
keep them for a long time.
Error analysis
An exception occurred that is explained in detail below.
The exception, which is assigned to
class 'CX_SY_CONVERSION_NO_NUMBER', was not
caught and
therefore caused a runtime error.
How to correct the error
Whole numbers are represented in ABAP as a sequence of numbers,
possibly
with an algebraic sign.
The following are the possibilities for the representation of
floating
point numbers:
[mantissa]E[algebraic sign][exponent]
[whole number part].[fraction part]
For example, -12E+34, +12E-34, 12E34, 12.34
If the error occurred in your own ABAP program or in an SAP
program you modified, try to remove the error.
If the error occures in a non-modified SAP program, you may be able
to
find an interim solution in an SAP Note.
If you have access to SAP Notes, carry out a search with the
following
keywords:
"CONVT_NO_NUMBER" "CX_SY_CONVERSION_NO_NUMBER"
"RSUVM001" or "RSUVM001"
"START-OF-SELECTION"
If you cannot solve the problem yourself and want to send an error
notification to SAP, include the following information:
1. The description of the current problem (short dump)
Information on where terminated
Termination occurred in the ABAP program "RSUVM001" - in "START-OF-
SELECTION".
The main program was "RSUVM001 ".
In the source code you have the termination point in line 96

Build the Bar chart from Cross Tab which have 3 measures with cell refr.cal
Hello Friends. I want to Build the Bar chart from Cross Tab which have 3 measures with Actual , Plan and Forecast
But Issue here is each cell is defferent like i have to do different calculation for each cell for actual, plan, forecast
like A = Jan act/Budget actual, Where as B = Feb Act/ Jan Budg+Febbdgt_March Budget
So now when I right click to say turn to Chart it is not generating the chart
Please help how to build bar chart since i do not have 1 key figure which i can drag and drop in view structure of chart so how to handle this
Jan, Feb, March, Aprl, May, June
Actual A B C D
Plan N M O P
Forecast
SONIYAHi Soniya,
It will be better if you can get these keyfigures calculated from the BEx with the help of structures in the BEx.
At the report level it will be complex to create these variables and also not sure whether going to work:
But you can try something like this:
A= If (L01 Moths="JAN") then Sum (Actual)/Sum (Bud) Else 0 similarly for other months.
Then you need to create one more variable (measure) which should be plotted on the chart as:
Final Act = If([L01 Month]="JAN") Then A ElseIf([L01 Month]="FEB") Then B ElseIf([L01 Month]="MAR") Then C
Final Plan= If([L01 Month]="JAN") Then N ElseIf([L01 Month]="FEB") Then M ElseIf([L01 Month]="MAR") Then O
similarly you have to create variables for Forecast, then finally you can plot final 3 variables in the graph.
Hope it helps you.
