Stopping the Output of Zero Values

I have been trying to find the easiest way to stop the output of values that are zero. I know there must be a an easy way, but I can't figure it out, maybe because I have never used labview before. Any help would be appreciated: see the attached.
The issue is with the primenumberlist. It outputs zeros and I'm trying to stop the output. I have included the other program so you can run the subroutine and see what I mean.

Thank you. I think I finally understand the function of the shift register. It's basically a "dummy" variable that allows the loop to go through and not terminate without doing anything to the loop.
One more thing, the output right now changed into a row format. How do I change it into a column? I tried used the transpose array feature, but that's only for 2D. Is there something that will transpose the 1D array?
The shift register is sort of like a "dummy variable". It would be like a statement x=x+1 in a loop in a text based language where the variable X stores a value between loop iterations just like a shift register stores a value in a wire between loop iterations. I don't quite understand or agree with you 2nd part about "not terminate without doing anything to the loop."
If you aren't familiar with shift registers, then make sure you take the LabVIEW tutorials.

There are a few different ways to do the columns vs. rows on your data. But I think the easiest would be to build your 1-D array into a 2-D after the For Loop and before putting into the 2-D array input of the Write to Spreadsheet File. You'll have to experiment to see whether you need to connect a True or False constant to the Transpose Array? input of the Write to SS File VI.

How to stop the output panel from displaying

Hi,
in CS5 (ancd CS3-4) how do I stop the "Output" panel from showing up automatically each time I test the movie using the Command+Enter keys? I know I have an error but it's a network error which does not effect my clip. it's annoying!

You can use F2 to close the output window. I dont think it can be stopped from displ

How to Supress the record having zero value

Hello All,
I have the situation where if the value is zero, i shoud supress the record not to show in the output.
This if for the purely a xmlP desktop report.
can some one let me know how to achive this.
Thanks

Hi PBV,
You can add one more condition.
For columns:
<?for-each:groupname?>
<?if:ELEMENT!='0' and ELEMENT!='' ?>
Col1 col2.....

Can I stop the output of PO message on change of order but not on creating

Can I set customising so that the PO automatically creates a message on creation of the order, but not when it is changed. That way the purchaser can choose to recreate the message if necessary. Sometimes changes are made to the order for internal purposes, but the order does not need to be resent to the Vendor. Currently this happens automatically via an email.
Alternatively, is it possible to print the whole PO when changes are made rather than just the bits that have been changed? To avoid confusing the Vendor with half the order being resent.
Thank you
Karen

This is not possible on standard SAP. There is a workaround you can consider so user can reprint the entire PO. When users have made the changes and ready to print the PO, they can go to PO message screen and do the followings:
1. Delete the entry corresponds to change message (this is the row with yellow light and has check mark in the C column)
2. Select the row corresponds to the first printing of PO (this is the row with now check mark in the C column) and press on repeat output.
Once they've done these steps, the entire PO will be included in the output.
If you need to make this happened automatically, you will need to do custom development.
Hope this helps.

Is there any way to stop the output of the iMac display to a connected TV?

I just bought an iMac 21.5 and successfully connected it to my plasma HDTV using a Mini Displayport to HDMI adaptor and HDMI cables.
Ideally, I would like to have the HDTV set up as a second display for watching movies, rather than mirroring the two displays. However, if I set the iMac video output in this configuration, it seems like it permanently keeps the 2nd display on, even when my TV is turned off. As a result, some of the functions I have on (such as triggering Expose) when I scroll to the corners of my display stop working, unless I change mirroring on, or if I physically disconnect the HDMI cable from the iMac.
My question is - Is there any way in software to disable the video output to Minidisplayport (instead of mirroring, or disconnecting the cables)?
If it turns out that Mirroring is the only way to solve this, my question would be - does turning out mirroring affect the main iMac LED display in any way?

How to stop PO output when the indicators are updated with a prog. **URGENT

Hi,
I have developed a update prg which will update the Final invoice indicator and Goods reciept indicator in SRM as well as in R/3 only for 'ORDERED' PO's. This was done using BBP_PO_PD_UPDATE FM. Everything is working fine, all the indicators are getting updated as expected both in SRM and R/3.
Only problem is that when the indicators are updated in SRM, PO Output is getting generated which should not happen.
Do you have any idea how to stop the OUTPUT.
This is very urgent.

How do I reduce the time from the detection of a input threshold to changing the output?

Hi,
I am using LabWindows 8.1 and a PXI-4461 with Vista (home) on a 2.81 GHz Dual Core Processor. I wrote code to do the following:
(1) output a ramp, input a signal concurrently (precise sychronization of these two is not important at this point)
(2) if the input signal rises above 0.5 V, hold the output constant for 2 seconds, while continuing the input
(3) finish the ramp
More info: I do a continuous sampling, with 4 samples per Write, to do the output. The input is read and analyzed with RegisterEveryNSamples (where N = 4). The communication between the tasks is through a global variable "trap," which is set to 1 when threshold is reached. I achieve holding the output constant by stopping the task (maintain existing value = true), and then restarting after the pause. At 40kHz and 4 samples per Write, the limit imposed by the discrete data blocks would be 0.1 msec, but in fact I am getting delays of about 2.5 msec. My write buffer is 120x4 samples, just so that there is space for me to write. I do need to save the input data after the
acquisition, preferably the whole sweep, but most importantly the data
while the output is held constant.
So my questions are:
(a) Does it really take 2 ms to stop a task? When I put in "Timer()" functions as below, I get a difference of 0.002, which is of course limited to the resolution of the Timer() function. Returning from a function (the EveryN callback) should not take that long, right?
(b) Can you suggest any better ways of doing this?

I would appreciate any help or advice! Thanks. (Sorry about oddities in the code.)

There are a number of applictations like Carbonite, Aperture, Entourage, VM Fusion, Parellels, etc that treat any change to the application as a complete change to application's database.
So, if you make one small email change in Entourage for example, the entire database is backed up on the next pass. As you might imagine, this can fill up a Time Capsule very quickly.
Suggest that you download a utility like BackupLoupe to find out exactly what is being backed up on each pass. Then you can exclude that item from backups if you wish.

PO,MIGO zero value item, not picking in MIRO

HI All,
In my Vendor Return Po one line item(Sample good) is created with Zero value.
GR and the entry is zero value. There is no issue at all.
But upon MIRO, it is automatically not seen in the line item
Can any one tell is it standard....or we cab bring the zero value line item in MIRO also.

Why are you mixing return and free item ?
Return is used to return material from your godown to vendor..
Free item is used to purchase material from vendor for free of cost...
If you maintain the free indicator in PO, then you are saying to system, that you purchase the item for free of cost..
You can see the Invoice Tab - Invoice Receipt option get unticked when you tick the free item in PO line item..
It will never appear in MIRO...

Stacked 100% bar chart - Problem with datatips for zero value data points

I have a stacked 100% bar chart that shows datatips in Flex 4.   However, I don't want it to show datatips for
data points with zero values.   Flex 4 shows the datatip for a zero value data point on the left side of a bar if the data point is not the first in the series.
Here's the code that illustrates this problem.    Of particular concern is the July bar.    Because of the zero value data point problem, it's not possible to see the datatip for "aaa".
Any ideas on how we can hide/remove the datatips for zero value data points ?        Thanks.

Zero value PO for internal processing

Hi ,
My client has a requirement where they need to raise Zero Value Purchase Order to IT Service Desk for procuring IT Equipments / Phones / Laptops .
So the service desk is our internal vendor who negotiates with IT Hardware providers to procure stuff ordered through PO .
Now I know that in the Invoice Tab at the item level we can un check the Inv Receipt to make the PO a zero value , but I am stuck with
1. What should be the combination in Account Assignment Category & Text Item Category ?
2. Also we don't want to create any specific materials for this and would like to populate our requirement in the description . For example " Order 5 blackberries" .
Please suggest the best way to do the same .
Regards
Anirban

> My client has a requirement where they need to raise Zero Value Purchase Order to IT Service Desk for procuring IT Equipments / Phones / Laptops .
If this is internal requirement, you should create a PR instead of PO and there is no need to enter the purchase price but still picks the valuation price from the material master but it doesnt have any impact in the accounts or purchase.
> So the service desk is our internal vendor who negotiates with IT Hardware providers to procure stuff ordered through PO .
Later your IT desk can negotiate with vendor and convert the PR into PO for the purchase. because you can't create a PO with zero value until otherwise if it's free item or consignment item. But in your scenario, you can't enter your IT department as vendor.
> Now I know that in the Invoice Tab at the item level we can un check the Inv Receipt to make the PO a zero value , but I am stuck with
I dont think this is right scenario, even though if you create ur IT department as vendor and create PO with "no invoice" this is not a right practise.

1. you can maintain the account assignment in PR depends on where you want to incur the cost(cost center, internal order) if this is direct expense. But if it's a stock item, you dont need to provide account objects in PR/ PO
2. You can create PR/PO without material by only maintain short text but you need to provide the account assignment. I dont think item category helps for your scenario.

Zero Value order

Hi,
I need to create a sales order with zero value.
ie, while creating a normal sales order, I am adding manual discount condition type with 100% discount.
While saving the order, system says, document is incomplete. I already checked the incompletion log for this and removed net value field from incompletion log, still the system is not allowing to save the order with zero value.
Any suggestion
Thanks in advance

Further, I am trying to create the billing with zero value,
billing document is getting generated, but accounting document is not getting generated with zero value,
When I put some value, then accounting document document is getting generated.
I have given 100% discount to the document and want to capture the discount value in some GL
how to go ahead?
Thanks in advance

I would like to compare two field and then is it's true then the output will be the 2nd one

Hello All,
I am doing a mappong where i need to compare two field and then if there are equal the 2nd one should be the output and 2nd value will be using multiple segment.
It's for shipment.
Regards
Rituparna

Not sure if i understand correctly. But you are trying to compare one field with multiple occurrences of another field.
You can make use of the node function "Use One as Many" and repeat the first value as many times as the second value.

Then you have to maintain info record for material and vendor in that inforecord you have to maintain value then at the time of sheduling agreement sys will not ask the value it will be taken from info record automatically..
Thanking you

PXI-6533, Changing frequency without stopping the card?

Using PXI-6533 and LabVIEW, is it possible to update the frequency (of a defined pattern) without stopping the output of the card?

Hi JX5000,
I don't have an example written for this use case, but you would use the property node in your while loop (perhaps with an event structure). I've attached a link to the LabVIEW Help file on this property node below. Hopefully this helps!
