Resetting data in a sub vi?

I've been working on a master program that will call sub-vis based on input from the user. My sub vi's are excecuted multiple times throughout the program and all of them use shift registers and/or feedback nodes. In the past hooking up a blank constant to the initilizer terminal has worked for me in order to clear data between excecutions but for some reason in this larger program its not working. I think Labveiw may be treating each call of the sub vi as part of the same excecution. Is there a way around this?
"There will be water if God wills it"

If the shift registers are initialized, the will reset the shift regsiter data with each call. If you use a globally initialized feedback node, it will only be initialzed on first run and not between calls. That might be your problem. (In both cases it will still initialize between executions).

How can I allow a sub-vi to run independent of the main program once it has been called while still sending data to the sub-vi

I have a main program where I call a sub-vi. In this sub-vi, there is a while loop that is used to wait for commands in the sub-vi. While the while loop is running, I cannot continue with normal operation of the main program. I would like get the sub-vi to run independently once it has been called, but not hold up the main program. As well, I need to still be able to send data to the sub-vi

One way is to use VI Server, which has been mentioned by others. This will allow you to start another VI (by name) and run it entirely independently of the calling VI. This is a good way to start various independent VIs from a main menu, for example. None of the VIs thus called need have any connection to the others.
Another way it to have the SubVI in a separate while loop on the calling VI's BD. Then, use a local var to start this sub VI from the main loop. The calling VI sets a local START bit and continues running. The sub VI's while loop watches for this START bit to go true, and then runs the Sub VI. The advantage here is that one can more easily pass arguments to the SubVI when it is started, using local vars, which are preferable to globals. Once the Su
bVI is running, however, you must use a global Stop Bit, set in the calling VI, to stop it when the calling VI exits, or the calling VI will hang up, waiting for the Sub VI to close and exit its while loop.
If you need an example of this, email me. ([email protected]). I can also recommend Gary W. Johnson's excellent book which discusses this. ("LabVIEW Graphical Programming", 2nd Ed).
Note: Where possible, I try to call a subvi from within the main VI, wait till it is done, then continue. It avoids the use of locals & globals, and results in cleaner code, with fewer "race" conditions. However, the main VI stops until the subVI is done, hence one should make the subVI modal.

SELECT records larger than date specified in sub query

Dear All
Thank you for your attention.
I would like to select records larger than date specified in sub query
query should be something like the following
SELECT my_order_number, my_date, my_task
FROM MYTB
WHERE my_order_number IN order_no AND my_date > date (SELECT order_no, date FROM MySubQueryResult)
(it is incorrect)
Sub query result:
order_no | date
A1 | 2014-12-21 09:06:00
A2 | 2014-12-20 09:07:00
A3 | 2014-12-20 08:53:00
A4 | 2014-12-20 08:57:00
MYTB:
my_order_number | my_task | my_date
A1 | T1 | 2014-12-21 09:06:00
A1 | T2 | 2014-12-22 10:01:00
A2 | T1 | 2014-12-20 09:07:00
A3 | T2 | 2014-12-20 08:53:00
A3 | T4 | 2014-12-21 09:30:00
A3 | T8 | 2014-12-23 20:32:00
A4 | T6 | 2014-12-20 08:57:00
expected result:
my_order_number | my_task | my_date
A1 | T2 | 2014-12-22 10:01:00
A3 | T4 | 2014-12-21 09:30:00
A3 | T8 | 2014-12-23 20:32:00
Any ideas? Thanks.

Hi,
try this
SELECT my_order_number, my_date, my_task
FROM MYTB
WHERE my_order_number IN (SELECT order_no FROM MySubQueryResult)
AND my_date > (SELECT date FROM MySubQueryResult)
Alternatively, you can also make use of joins to achieve the same.

Dear Praveen Dsa
Thanks for your reply, but order_no and date are paired and related, cannot separate.
each order have its own date, so it is not working

Reset date in FI table ( Resetting done through FBRA transaction)

Hi Experts,
I am an ABAPER currently developing one report regarding reset of all customer payments in a given date.
But i could not find any table where there is reset date. Once we reset the document the account document entry date (CPUDT) is the date when the document is created instead of resetting date(CPUDT is not modified to resetting date
). I have also checked all the fields of BSID , nowhere i could find reset date. Can anyone help me in getting the reset date(done through fbra transaction) in any FI table.

Hello,
Check table BKPF table.
In BKPF table, you can get STLBG field for clearing document which is reversed by FBRA. In BKPF-STBLG, you can see reverse document number also see reverse document fiscal year in STJAH.
Then you should select BKPF table for BKPF-STBLG and BKPF-STJAH fields. In result, BKPF-BUDAT is the reset date.
I hope it helps to you.
Regards,
Burak

How to reset data Warehouse table

For fixing some mistakes, I'd like to reset the whole Data Warehouse tables ( clear alll data in the tables).
Is there any way to achieve this with DAC client?
Roger

Nothing to worry. We have the option in DAC. Navigate to Tools -> ETL Management -> Reset Data Sources. Give the confirmation text in the dialog box. With this action the refresh dates will become Null for all tables and which causes to do a full load in the next ETL run.

Need to reset Data Warehouse

Hi,
I need to reset the Data Warehouse so that i can begin my first ETL Process. However, I'm not able to do so from DAC Client ver 7.9.5. When i click on "Tools" --> "ETL Management" --> "Reset Data Warehouse" nothing pop up's. Not sure why, all other links and windows opens, except for this. How can i get this fixed ?
Is there a way for me to do the reset manually ?
I checked on internet and found AS BELOW :-
D4 How do you run a full load (not incremental)
A: Reset data warehouse . Just truncate the S_ETL_REFRESH_DT table in the dac repository
So in our case the table to truncate will be W_ETL_REFRESH_DT rite ? Please confirm. We are scheduled to run the ETL at 6pm today.
Is there any other tables that i need to truncate as well ?
Thanks,
Saran.

Hi
W_ETL_REFRESH_DT is a metadata table on which you should never perform truncate operation.
Also,Whate 'Reset Datawareshouse' does is it just updates last_refresh_dt of w_etl_refresh_dt to NULL.
So,all you need to do is
update w_etl_refresh_dt set last_refresh_dt=NULL;
commit;
Hope this helps.......

DAC - Reset Data Sources does not work properly

Hi,
I am trying to run a full load by selecting Reset Data Sources in DAC. However, when i select this option, only the data after Jan 11, 2014 gets picked up in the ETL. I have data starting from year 2010 in my database.
How do i ensure that the full set of data gets picked up for full load?

Hi Srini,
The value of INITIAL EXTRACT DATE is as follows:
$$INITIAL_EXTRACT_DATE
Timestamp
Value=19700101 at 00:00:00:00_dac_sep_Formatter=MM/DD/YYYY_dac_sep_Function=TO_CUSTOM_dac_sep_Runtime=Static
How does this work? Actually this was working fine for DAC 10g and the client was able to perform full loads by resetting the data sources.
What could be the issue with DAC 11g?

What is the Fair Usage reset date?

I am close to going over my usage limit.
I want to know the date it gets reset, so then i can slow down on my internet surfing until that date.

Reset Date in Quality Level / DMR.

Business Requirement = Vendor Annual Certification. All batches received by the vendor during the year goes through minimal inspection and on the 365th day (reset period (days) in DMR) it changes to the initial stage of the DMR.
However, the reset date field in the Quality level screen resets itself on the basis of the "date of last Inspection" field in the same screen. This field changes every time a UD or MIGO is executed. Therefore, the true 365th day is never reached and so the quality level never resets to the original stage.
I'd like to change the functionality of the reset date in the Quality Level screen to reset after the yearly requalification sample (to conform to the reset period in the DMR), as opposed to after every inspection UD/MIGO. The reset date should "reset" after the initial inspection stage (in the DMR) is completed.
Is there a way to do this through config or a user exit, or something else? Thanks in advance,

To fulfill this requirement created DMR as following:
Stage -1: InspeServ-4, Skip - Blank, Ist - Select check box, Stc - select, No of insp - 1, Next stage -2, reject -1, Nect -Stage 2.
Stage 2: InspServ - blank, Skip - select check box, Ist - skip, Max. skip duration - 365, next - stage 1, reject - 1, next - stage 1.
Hope this would help you.
Thanks!!!

Gen. 2 iPod Touch is stuck on Apple Boot Logo after Resetting Data/Settings

My iPod Touch hadn't been getting recognized by iTunes and my music wouldn't sync onto it so I went into the Settings app and clicked Reset Data & Settings (the 4 hour long reset) and waited while the bar slowly moved until it finally restarted and showed the Apple Boot Logo. I then waited for about 20-30 minutes for my iPod to turn on and it never did, so I reset it by holding the Power+Home button and that didn't do anything as it was still stuck on the Apple Boot Logo. Then I remembered I could have just put my iPod into DFU or Recovery mode to get iTunes to recognize it to reset it, so i tried to put my iPod into both modes and it wouldn't go into them. So I went to bed and just woke up and it's still stuck. I'm afraid I might have bricked my iPod, and I'm out of my warranty I believe. Does anyone know ANYTHING I could try? I don't care about data loss seeing as I already tried resetting the whole thing.

If it is still doing it after a restore, you most likely have a hardware issue.

Why does iTunes and Safari reset data everytime its closed

I have a power mac G5 and after I updated to the highest software update available, I find that iTunes and Safari reset their data everytime I close them. I have checked all settings and tried resetting to regular software and trying again. Any ideas?

Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
