Not obtaining all data due to write to file

I am very new to LabVIEW, as in 3 days, and have not been able to figure out my problem with losing data while trying to write to a .txt file. I have a load cell that I am attempting to obtain data from, but when I go to the waveform data I am losing approximately 2/3's of my data and am worried that an event will be missed and the data cannot be used. Because I'm new, I am not good at troubleshooting/debugging and am looking for any help or guidance. I have attached an image of what I have.

Hi there,
I think your basic problem is that you're obtaining your samples in individual lumps by collecting N samples then plotting and writing them to disk. If you change your task to a continuous acquisition say acquiring 10 samples at a time at 10Hz then the loop timing will be handled by the acquisition and the amount of data to be saved will be done easily within 1 second. See sample below. In this way you'll be constantly acquiring data and writing it to disk with no gaps.
If you want to run the acquisition faster than say a kHz then I'd follow the suggestion made in the previous reply and stream the data to a separate loop via a queue just in case the disk write takes longer than the loop time.

AP PAYABLES- Not getting all the DUE DATE's in with split schedule payments

Hello All,
We have some issues with AP Data loading's into our DW from EBS 11.5.10 AP - PAYABLES.
One of our customer is using split schedule and share payment into few payment. Our
sql is not reading all the due dates for PAYABLES.
We are using PAYMENT_NUM=1 from ap_payment_schedules_all table as condition to load the Data to avoid duplicate rows coming for Payables.
Some hints: removing the "PAYMENT_NUM=1" from the where clause gives all the due_dates but then we have duplicate rows for Payables.
Please help to modify our query so that it will work for split schedule payment.

Why the 2LIS_08TRTK extractor can not get all data

Hello, BW Gurus.
Why the 2LIS_08TRTK and 2LIS_08TRTLP extractors can not get all data. I had used the RSA3 and get 10 registers, when a check at the VTTK table I had 20 registers, I didnt use filters at RSA3, could you help to know what happen o correct it.

Is it because
<i>
Shipment documents and their dependent objects (shipment stages as well as shipment items [deliveries in the shipment]) are only extracted into BW when the Shipment completion status has been set.
This is necessary because the numeric values that result from the delivery documents are only established at the time. If the data were already stored earlier in BW, the shipment data would not be updated if the delivery notes were changed in BW.

Itunes will only sync a portion of my music since i have installed the newest update. It keeps telling me it can not sync my Ipod due to a duplicate file name. Any suggestions?

I am trying to get some advice as to why my Ipod will not completely sync since I updated Itunes. Itunes keeps telling me it can not sync my Ipod due to a duplicate file name? It will sync some of my songs but not all of them. Any thoughts?

Most likely the iPod filesystem is corrupted, during a partial sync, that freeze due to a timeout.
In My Computer, select the iPod, right click Properties->Tools->Check Now
tick both Fix filesystem and scan.for bad sectors.
This will fix the duplicate name error.
Good Luck!

Unwrap not unwraping all data sent from server

java client server NIO ssl
At server end send about 50 packets are written using this method:
sendPacket(String packet)
writeBuffer = charSet.encode(packet);
c.ssl.outNetBB.clear();
c.ssl.engine.wrap(writeBuffer, c.ssl.outNetBB);
c.ssl.outNetBB.flip();
//write message to socket channel
while (c.ssl.outNetBB.hasRemaining())
socketChannel.write(c.ssl.outNetBB);
At the client end I read all these packets:
inNetBB.clear();
int bytesread = socketChannel.read(inNetBB);
inNetBB.flip();
requestBB.clear();
res = engine.unwrap(inNetBB, requestBB);
It seems like all the 50 packets are read into inNetBB 6000 bytes
But the unwrap only consumes 70 bytes and produces 100
This first 100 bytes is unencrypted correctly and corresponds exactly to one write of the 50 from the server. I dont know why.
Why am I getting only the first packet of the 50 sent??
[ Ive tried : while inNtBB.hasRemaining for repeated unwraps
but only the first packet is output still ]
TIA
pbutler

If I'm reading this right, you're writing (wrapping) about 50 separate SSL packets, and then unwrapping just one.
Recall:
The SSLEngine produces/consumes complete SSL/TLS packets only, and
does not store application data internally between calls to wrap()/unwrap().So it looks to me like you need to keep unwrapping the rest of your 5930 bytes to get the remainder of the application data.
[ Ive tried : while inNtBB.hasRemaining for repeated unwraps
but only the first packet is output still ]Are you inadvertantly clearing the inNtBB before you call your additional unwraps?
If you have lots of small packets, you might want to consider buffering them up and wrapping them to the SSLEngine/SocketChannel all at once. You'll pay less in overhead.

2lis_11_VAITM not inserting all data in ODS

Hello Gurus.
I'm using extractor 2lis_11_VAITM, when I test the extractor in RSA3, it is bringing me all registers of table VBAP, but when I load this extractor into an ODS in BW, It is not inserting all registers into the cube, some "return orders" are missing, how can i solved this problem ???? I'm using in ODS key Doc number and position.
THANKS IN ADVANCED.

Hi Sudheer, ther is no selections during data load, and also ther isn't any routine(either in transfer or update rules). It's supposed that all registers have to be loaded to the ODS no ?? because i'm using key Doc number and positions, so I want all documents with all positions to be loaded, but this is not happening, there are missing the "'return orders'".
Any other idea of why this is happening ??

FDM export to HFM - 2nd export did not clear all data from 1st export?

Has anyone experienced exporting a replacement FDM file to HFM where the 2nd file did not contain an account that was present in the original file and that account/value in the 1st file then remained in the HFM trial balance and caused it to be out of balance? Does the replace export option not clear all the prior file data? The only unusual part of it might be that the problem account was derived using logic group script? Thanks.

Thanks Hensen - Sure, it was easy enough to fix once I deduced what the problem was - although my solution was just to use the data clear function and reload. The real question is how to prevent it from happening again and it sounds like I can't do much about it - other than trying to train the users to watch out for do-over files that have fewer accounts than the original load?? Am I wrong to think that HFM should try to fully clear all previous data from a load file if there is a replacement or at least try to validate whether or not all prior accounts have been repopulated?? There's plenty of good validation in the validation step of FDM. Why not during the export step? If this makes sense, I'll put in another "enhancement request" to support.

Help: Not getting all data from text data type

Hi there
I have a stored procedure that returns a couple of fields and one of the fields is of datatype TEXT. In my ResultSet, I do not get all the data back that is stored in the TEXT datatype. I have say about 600 charactors in this field, but only 30 charactors are returned. Is there a reason why this is happening and how can I fix it?
Please help?
Thanks

I set that field to have a normal string of about 50 charactors. Namely: "this is a note that is about 49 charactosrs long." (exclude the quotes). And I still got 30 charactors back only.
I set a shorter text value of 21 charactors and that returned all 21 charactors.
The text that is usually in this field is:
"URL=SubsidiaryNarrative.html�BABY_CARE_PRODUCTS=false�AIDS_FOR_PHYSICALLY_DISABLED=false�SPORT_SUPPLEMENTS=true�NATURAL_REMEDIES=false�COSMETICS_FRAGRANCE=false�WOMANS_HEALTH=false�ADDITIONAL_CARDS=No�EXERCISE_ROUTINE=Yes�NUMBER_OF_CHILDREN=0"
And I got out "URL=SubsidiaryNarrative.html�B"

Ical not storing all data & cant initialize lists

okay so im trying to store all ical data in seperate lists for hours months years and the actual event ect....it worked fine for a while but now its not storing all the events....and then when it did it would carry over from one run to another. I figured out that was probably because they were properties but when i make the lists global i get a "this variable is not initialized" problem. and even if i somehow managed to fix that its still not reading in all the data. ive been at this for 2 hours and cant see the problem. please help:

You need to be careful when using conditional statements to set global variables (the global declaration does not set any values). I can't tell from the just the one handler you posted, but an example would be the iCal_Run variable - unless it is declared somewhere else, it won't have a value if there isn't an iCal process.

St03N not collecting all data

HI
does anyone know why would st03n not collect all proper data, we found out recently that a user had scheduled a program as a background job to run and it ran successfully but when we look on that date we don't see that it had run and even that user doesn't come out in the history
any ideas why?
regards

Sorry Sujit that I wasn't clear
the job i was referring to was a z program that was run be a user in the background.
that is how we started knowing that there were missing data in st03n
we were trying to see how many time that program ran and who ran it
so we went to see in st03n but we found out that there was no history for that program in there or any history for the user who ran the z program in the background.
there is no connection to SAP_COLLECTOR_FOR_PERFMONITOR background job. this job is running successful in our system and all other data is being collected
so the data that was missing was on the 14th of march and then we found out that there is no entry of any sort in st03n for 15th of march, but we have data for 16th of march.
so now we want to know what happened
i hope this is clear now
regards

Emails do not download all data

Emails do not download all data

Try reset iPad
Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears
Note: Data will not be affected.

Final user's can not see the data due to limited authorization.

We have created a InfoSet with three info Objects, 0Account, 0Costcenter and 0COMP_CODE. 0Costcenter have an attribute retail location 0RT_LOCATIO.
0RT_LOCATIO is an authorization relevant object. We as consultants can execute the infoset properly, but final user's with limited authorizations can not see the data because of authorization failier
We hae several options to solve the issue, deleselect the auth. flag in the infoobject; delete the infoobject from the attributes of the cost center or create an authorization object and assign it to the final user's profile. But we don't want to go that way.
My question is, is there any way to avoid including this attribute in the infoset definition? We are not using it in the query and we don't need it, so if we could delete it from the infoset (in the same way you add or delete infoobjects from an Infocube) without changing the cost center aster data, we will have our problem solved.
Does anyone how to do this (if possible)?
Thanks in advance!

Just do two things to find the authorization check failed for that user.
1. Execute SU53 output and find out the authoirzation check failed. If yes, please send that to BASIS Team.
2. Next one, switch on the authorization trace in ST01 and ask that user to see that data. if the user is failed with authorization issue. switch off the trace in ST01 and find out the issue.
Do this way, if it is not successful you can go for any other alternate way.
Hope this would help you.

VO not retrive all data

Hi
I create view object for entity, the query of view object not return all record from database. Is there any option for fitch all record from database?

JDev version?
Technology you use?
Where do you look for the all(?) rows?
If you are using ADF there is a fetch size defined by the iterator (normally 25) which limits the number of rows returned for one round trip. To see more records you have to scroll.

MI 7.1: Obtain all data from bapi wrappers

Hi, i have my SWCV, i import various bapi wrappers... How can obtain the data from this bappi wrappers?
If i go to view metadata, in CDS Entires, appear more than 0, mean that i have the data?
I upload the application to the device, but i don´t receive the data.
Can anybody help me?
Thanks,

Yes, i have it... But i don´t receive the data...
It seems than only receive data from GETDETAIL, i think this because my GETLIST need the user, and if i do the initial load of data, here, there isn´t user...
Thanks,
PD: i think that in Mapping Tool should appear GETLIST...

Substitution variable is not visible at Data Prep editor-creating rule file

Hi,
We are working on Essbase 9.3.1, Oracle as a database source for loading the data into Essbase.
We have create a substitution variable at "server level" to use it in rule file as a DSN for data source. But this substitution variable is not visible in the drop down of substitution variable in 'Data prep editor' while creating the rule file.
We restarted the Essbase server also but still it is not visible in 'data prep editor'.
Any help will appreciated on this issue.
Thanks & Regards,
Mohit Jain

Cameron-
1) yes I've tried it on 2 different clients
2) yes I've tried it on the server
3) I haven't tried that, but don't normally use MaxL for anything
4) I took a 'broken' rule, saved it locally, closed and reopened and it still didn't work
5) I normally do files on the server, but I can't even get to that point because when I get the 'Open Data File' nothing happens, no dialog box pops up, so I don't get the chance to select the location
6) This is a production server and EAS is running as a service, so I'd have to test this one afterhours.
Because it happens on 3 separate PC's I'd eliminate bad EAS, since only some rules do it and others don't I'd think it could be corrupt rules, but it'll happen to new rules just as fast, and they still work just fine, so if that's the case I need to figure out what is corrupting them...
Network issues wouldn't surprise me, I get TCP/IP errors regularly saying I have to increase my net retry count, but I've tweaked with those settings tons... looks like those are really the database server is running out of memory even though I have 4GB physical 16MB Virtual memory (32 bit environment though... I do have the /3GB switch turned on)... I've had to scale my caches way back to allow certain databases to even function.
Thanks for your help.
