How to use a transferfunction as a sub VI

Hello,
Iam trying to make a pid controller.I succeed when I used a transferfunstion H(S) as the parameter to control.It is attached with the name controlsystemdesign.vi.But my aim is to use my own transfer function pidcontroltransfun.vi instead of H(S).But I dont know which one will be the input and output connectors.Please check the attached VIs and help me to solve this problem.

I would use a Producer-Consumer archetecture. If the fp is something that will be accessed frequently, consider using an Event structure; otherwise, use your sub-VI to trigger the event you wish to start. Yes, you can use your sub-VI to trigger an event in your main program (P-C data or event type). There are many ways to do it. What type of signal are you trying to measure? Do you want it to trigger on a certain condition/measurement?

How to use CSAP_MAT_BOM_MAINTAIN for deleting / changing sub-items?

I'm trying to use CSAP_MAT_BOM_MAINTAIN for BOM create / change / delete.
Issue: This Function module is not working when I'm trying to delete / change sub-items of a BOM. I'm getting update termination (ABAP/4 processor: SAPSQL_ARRAY_INSERT_DUPREC) during BOM post.
Is there a way to fix this?
(1) BOM creation part is working fine
(2) BOM item (without any sub-item change) change / delete is also working

hi
The following parameter are important parameter and mandatory
Matnr ; Enter the material Number
BOM_USAGE : Ther many BOM available that is sales BOM and Production BOM etc here you need to mention usage of BOM that is for sales or production
I_STKO : Enter the BOM Header information . Note : Ask your Functional consultand
Apart form this parameter, all are optional so do worry

How to use FC to make a sub-component for Flex

Most of the examples and tutorials I've seen so far assume you are creating the app itself in FC.
However, what I need to do is create a custom component that will be a "screen" in a large Flex app, like a page in a Wizard.
So if I was doing this without FC, I'd make a new mxml component in Flex, e.g. "WizardStep.mxml" and then in the main app,
<mx:ViewStack>
<h:WizardStep id="one" label="Step One" />
<h:WizardStep id="two" label="Step Two" />
</mx:ViewStack>
For example, assuming I have set up the namespace "h" to like "com.handycam.*"
How would I accomplish this scenario if "WizardStep" is what I have been building in FC?

Thanks for your answer!
Unfortunately it still doesn't work.
In FC I used the file menu item "publish as swf" ( or however it's called in English -
I'm also struggling with the -unwanted- German workspace terms). This generated
the deploy-to-web and run-local folders. In Flex3, I imported haupt.swf (=main.swf)
from the run-local folder.
When I use the imported file in the Image tag with the
loadForCompatibily attribute set to "true",the application compiles,
opens the IE, the remaining LinkBar buttons are not affected - they
show/run the Flash Pro .swfs and their controls,
but the attempt to access the .swf in question produces:
VerifyError: Error #1053: Illegal override of z in mx.core.UIComponent.
at flash.display::MovieClip/nextFrame()
at mx.managers::SystemManager/deferredNextFrame()[C:\autobuild\3.2.0\frameworks\projects\fra mework\src\mx\managers\SystemManager.as:319]

at flash.utils::Timer/_timerDispatch()
at flash.utils::Timer/tick()
The alternative approach:
<mx:SWFLoader x="3" y="35" width="970" height="425" loadForCompatibility="true" source="insets/haupt.swf"/>
produces:
VerifyError: Error #1014: Class flash.text.engine::TextLine could not be found.
at global$init()
If I code the SWFLoader tag as:
<mx:SWFLoader x="3" y="35" width="970" height="425" loadForCompatibility="true" source="
@Embed(source='insets/Haupt.swf')"/>
I get the same errors as I did for the Image tag approach.
Hope this helps.

How to use an Aggregate in a Computation on an Interactive Report?

version 4.0.2.00.07
Hello,
I'm trying to create a computation on an Interactive Report from the Actions menu to compute a percentage.
I have two Status columns, one for open and one for closed. I have to count the number of open and count the number of closed and then divide the two.
I created an aggregate, count, on the open status and closed status, but how to use them in the computation? There's no 'count' in the Function list in the Compute box.
I was hoping that those aggregated columns would be displayed in the Compute sub-menu on the Actions button but they don't appear to be.
Can someone help me with this?
Thanks,
Joe

Maybe an alternative would be to put this logic into the select.
select u.object_name,
       u.object_type,
       count(case when u.object_type = 'TABLE' then 1 end) over () count_tables,
       count(case when u.object_type = 'VIEW' then 1 end) over () count_views
from user_objects u;This would count the number of tables and views in the data dictionary. And it is returned as a column value.

How to use application class reference in the controller methods of BSP

Hi,
I have created a bsp application and also created an application class and assigned it to the application class. In the application class, I have created attribute TEXT type string(public and instance parameter).
In the controller let's say main.do, I am trying to give a value to to the text by adding the following code.
application->text = 'test'.
I am getting syntax error saying field 'text' is unknown. It is not contained in one of the specified tables nor defined by DATA statement.
Please can someone let me know how to use the application class in the coding with an example. I couldn't find how exactly this has to be reference. Please help.
Best regards
Siva

Hi,
if you are having main controller and sub-controller then you may need to use below coding to use application class reference.
*Data declaration
DATA: obj_cntrl        TYPE REF TO cl_bsp_controller2,
         obj_sub_cntrl   TYPE REF TO z_cl_sub_cntl,
         application TYPE REF TO z_cl_application.
*Get the controller
CALL METHOD obj_main_cntrl->get_controller   "obj_main_cntrl is the object of main controller
    EXPORTING
      controller_id       = 'SUB'   "Controller ID
    RECEIVING
      controller_instance = obj_cntrl .
obj_sub_cntrl ?= obj_cntrl .
application ?= obj_sub_cntrl ->application.
or simply use below code in your controller method.
application ?= me->application.

How to use synonyms on multiple word search ?

We use context with multiword search like this one :
select * from my_table where contains(my_text,'the small building near the river')>0
Now we have specific synonyms in a thesaurus. How do we write the contains clause ?
contains(my_text,'syn(the,thes) and syn(small,thes) and syn(building,thes) and syn(near,thes) and syn (river,thes)')>0 does not fin the synonym for "small building"="house" for instance
contains(my_text,'syn(the small building near the river,thes)')>0 does only for synonyms on the full sentence.
More generally is there an Oracle Document which describes how to use SYN, FUZZY and combine them, since
the reference documentation gives only limited information on this ?
Have a nice day

The thesaurus functionality is not currently built for stuff like this.
if you want to combine fuzzy and thesaurus, I am assuming you want to do fuzzy first, to correct any misspelling,
then thesaurus on the "corrected" spellings? You'd have to do something like:
1. take the query and run ctx_query.explain to break it down and do the fuzzy expansion
2. work through the fuzzy expansion and build a new query string by sticking SYN() around each
expanded word
As for thesaurus expansion and phrase, these are not compatible. Thesaurus expansions use "," and "|", and so
you cannot have a phrase of thesaurus expansions.
I see what you're getting at, but you would need sub phrase detection, phrase equivalence, etc., which is
currently beyond the thesaurus function capability.
You can use themes (ABOUT) on phrases, and it will do something like what you are describing. You might want
to check that out.

How to use an external hard drive on a MacBook Air?

Hi there.
Recently I bought a portable USB external hard drive for my MacBook Air due to my full startup disk. I also bought multiple disks for the hard drive. I inserted the disk, hooked up the USB, and did everything properly. When I first hooked it up, I lost all internet files that I had saved. All images, videos and downloads (such as Minecraft and other gaming downloads) from the internet were gone and unable to find.
Now, I don't want to make the wrong move and lose all of my internet files again, so I am asking how to transfer files SAFELY to the USB without any files being deleted. I tranfered files before, but they were just short cuts to the original file, so I am also asking how to fix that as well. My Dad was a computer technician, although he didn't work for Apple, so he doesn't know how to use the USB.
I've tried everything to find my internet files, but nothing. If there is a way to get them back, I'd be glad if you shared that with me. My dock files aren't working due to this insanely full startup disk, so I'd appreciate it if you could tell me ASAP how to use the USB, how to SAFELY transfer files without them turning into shortcuts, and how to get my internet files back.
Thank you very much.
P.s My OS X version is 10.8.3 (Not with Mountain Lion)

You cannot format a drive so that files will be automatically put on that drive when you run out of room on another drive. Transferring the files must be done specifically by you. You will need to learn how to manage free space on the SSD because 64 GBs is a bit small for much more than OS X.
Drive Partition and Format
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.

How to use Object Class:orclDbServer in OID

Not sure if i have posted in the correct forum, I am quite new to OID
I am planning to use orclDbServer Object Class, but not sure how to use, i have searched in Google, and Oracle Documentation, there are so little information about this, there are only:
Object Class: orclDbServer
Description: Defines the attributes for database service entries
Attributes: orclNetDescName, orclVersion
Below is the ldif file i created for add one entry with object class orclDBServer:
dn: cn=orclDBServer_test, cn=OracleContext, dc=ldapcdc, dc=lcom
changetype: add
objectclass: top
objectclass: orclDBServer
cn: orclDBServer_test
orclNetDescName: (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST=10.182.114.121)(PORT = 1521))(CONNECT_DATA = (SERVER = DEDICATED)(SERVICE_NAME = oh112)))
after i use below command to add this entry:
ldapadd -h localhost -p 389 -D "cn=orcladmin" -w welcome1 -f test_add.ldif
then use ldapsearch to search:
ldapsearch -h localhost -p 389 -b "dc=lcom" "objectclass=orclDBServer"
the result is like below:
cn=orclDBServer_test, cn=OracleContext, dc=ldapcdc, dc=lcom
cn=orclDBServer_test
orclnetdescname=(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST=10.182.114.121)(PORT = 1521))(CONNECT_DATA = (SERVER = DEDICATED)(SERVICE_NAME = oh112)))
objectclass=top
objectclass=orclDBServer
objectclass=orclService
It seems it added a line for me:
objectclass=orclService
Is there anything wrong with my ldif file when i want to use orclDbServer?

How to use Aggregate Functions during Top N analysis?

Say i want to find top 5 highest salaries and their totals and average. In that case how to use aggregate functions. Please give me an example on this.
Regards,
Renu
Message was edited by:

Hi,
Yes, you can do that with aggregate functions.
First, do a sub-query to retrieve all the salaries (in descending order), then say "WHERE ROWNUM <= 5" in the main query. Use the aggregate SUM and AVG functions in the main query.
Analytic functions are easier to use for jobs like this, once you get familiar with them. If you're not leaving the field this month, then it's probably worthwhile for you to get familiar with analytic functions.

How to use the keystroke feature of applescript?

I am trying to use the keystroke feature of Applescript.
On page 200 of "Mac OSX Panther edition The Missing Manual" shows the following example (to select all of a document):
keystroke "a" using (command down)
I tried to use this with keystroke "o" and got the message that "using" can't be used this way. Where can I find a few examples of how to use this feature in Applescript? I particularly want to use keystrokes to copy rulers in Appleworks. The keystrokes to do this are "shift-command-v".
Thanks for comments.

While I agree with Hiroto as to how to implement 'AppleWorks 6's 'Format, Rules, Copy Ruler' ('Command <shift> C) sub-menu item selection, below is an example of performing the same action using 'keystroke'.
tell application "AppleWorks 6" to activate
tell application "System Events" to keystroke "c" using command down & shift down
Below is an example of performing 'AppleWorks 6's 'Format, Rules, Apply Ruler' ('Command <shift> V) sub-menu item selection using 'keystroke'.
tell application "AppleWorks 6" to activate

How to use batch mode in cq dam - new questions added

Hi I am doing DAM migration. I am using custom code to pick the image and create asset by calling Assetmanager.createAsset which creates dam assets.
This code I am calling through the scheduler which will run for every 0.5 hr. Around 1000 images we are trying to push in each cycle. I came acrosss batchMode for saving all the images per batch so that it will reduce the migration time But I am not sure how to use it.
.setBatchMode(true); isBatchMode are the methods available in Asset api.
Please share your thoughts on this.
Some more Point I want to ask.
1.What is the best appraoch when we are pushing images to DAM
     Stopping the workflows push all the images and run the work flows. (Is it possible to do this?)
     Do the both simultaniously
     Do it in the bath (i.e push bunch of images and then run the workflows)
2.When i am migrating images (from file system which is residing in the same box where cq is running )it is almost taking 0.5 hr for 1000 images (avg size of image is 100kb). Is there any possibility to      improve this process.
3. When I am adding images I am adding subassets to some of the images so when ever I add subasset cq is creating new version of the asset which is not required for me. What is the best approach to avoid      creating too many versions for images in DAM. By doing this is there any performance improve in the system.
Thanks,
Maruthi

Hi Jorg,
Thank you.
I will try out batch saving option.
I have few more doubts.
1. Today I tried for moving aroung 5k images through the scheduler in my local machine. It went smoothly with out much issues but as usual some of the renditions are failing for some of the sub assets. This is about 3 for every 10 images. Renditions are generating properly for all assets it is failing in case of sub assets only. Along with this I am getting version exceptions. Below are errors which I am facing very frequently during migration dry run. This seems to be beacuse of the non synchronized execute methods in WF steps. What is your call on these issues how can we avoid these kind of errors.

Cause: Unable to perform operation. Node is checked-in. javax.jcr.version.VersionException: Unable to perform operation. Node is checked-in.
2. Can you share about experience in DAM migrations. What is the avg time it takes for migrating about 1 to 1.2 lac images which are aroung 60    gig. We thought of running the scheduler (this.scheduler.addPeriodicJob(jobName, job, config, period, canRunConcurrently);)for every 0.5 hr in that case it will go on for 3 days.
