Pre and Post Sends

Although I understand the principle and consequences of changing my sends from post to pre fader, I can't for the life of me think of a situation where this would be desirable. Can someone enlighten me?
Cheers,
Simon

This is very desirable in lots of situations. Like already said, sounds can dissapear into or appear out of a huge reverb space, weird delay rooms-whatever. When sending signals e.g. to a sub bass plug you don´t want to follow the send your volume automation to get a steady and good signal to trigger the subbass plug. Altogether pre fader is a very important mix tool

Pre and Post for Sends..Confusion?

Dudes...am I crazy?
I have 2 tracks. One plays a vocal and one plays a guitar. Both are sent to the same Aux or Bus track with a reverb on it, via the sends on their respective channels.
If I solo the guitar track, I still get reverb tails from the vocal track on the bus channel as well as the guitar!
If I switch the vocal track send to "post", then the reverb tails go away for the vocal. By the way, I'm soloing from the mixer channels, not the arrange window.
Now I understand that if it were the vocal track that I had soloed then switching between Pre and Post on the send would dictate if I hear the reverb tails or not for the vocal track.
But that's not the track I have soloed! I have the guitar track soloed. So why would I hear reverb tails on a track that's not soloed. And why would the reverb tail go away on the vocal track if I change the send to Post, when that's not the channel I have soloed.
Am I crazy, or should logic know that if I have a track soloed, it should not play anything else but what's on that track? Regardless of switching from pre to post, if the vocal track is not the track that's soloed, why am I hearing anything from that track at all? I shouldn't have to mute the vocal track or switch it's send from pre to post, just to hear the soloed guitar track by itsself.
Thanks

You say you love Logic's "pre/post mute send solo safe function". Sounds like quite a function Does that mean it's changeable in Logic? You make it sound like it's an option.
By the way, I understand that if you solo a track, it might be cool to also hear it's effects channel without having to solo the bus track its feeding.
But why would I hear another tracks effects? This only happens when two different tracks have the same bus inserted in their sends. Just because I'm using the same send for two different tracks, doesn't mean I want to hear both sends even if only one track is soloed. That's the part that makes no sense for me. Solo should only address and isolate the track that's soloed and whatever else is related to it (ie...busses/sends/plugs etc..)
I dunno, I guess when you solo a track it keeps open the bus/send it's using unless your exercise the pre/post send option. And if there's someting else using that bus send as well, it must need to stay open for it too.
By the way, for me sometimes Logic will continue to play a certain audio track, usually a single track of it's choosing, even if another track is the only one soloed. There are no busses, no plugs, no sends on it, just a straight track and I still have to mute it after soloing some other track. Now that's not right...pre/post etc...is not in the equasion here, can someone explain that?
Thanks for the help.

BW upgrade - pre and post upgrade reports

Hi All
Quick question please.
We plan to upgrade our BW ABAP system from NW 731 SPS7 to NW 740 SPS6.
I read the ASU toolbox note 1000009 and can see that there is no file for our scenario i..e from 73X to 740 so note 1734333 is the way to go here when prompted for ASU toolbox run. However within the note 1734333, it states "This note requires that all pre-requisites for the BW-related system copy automation are met according to note 1707321". When i read 1707321 it talks about installation procedure for PCA which is part of LVM, a licensed software. We don't have this license. Hence I am wondering if note 1707321 is applicable for us at all or is it that this note would bring about changes in the system and sets up a staging area upon which the Z report from the other note(1734333) builds and then creates task list for pre and post upgrade. I am certain that we will have to implement Z report from note 1734333 however the reference to note 1707321 has created some confusion.
Also once we implement the Z report from 1734333, the note says, the report needs not be transferred but the objects generated need to be. Would the author here referring to reports - SAP_BW_BEFORE UPGRADE and SAP_BW_AFTER UPGRADE and having them recorded into a transport. Any thoughts here please. If the author is indeed referring to these reports only, how do we know this will show up in quality systems via STC01 as input options.
Regards
Kalyan

I re-read the note again, It says, If task manager content notes(1707321) are not applied, we will not see reports for stopping RDA Daemons and Process chains i...e report RS_SYSTEM_SHUTDOWN. However we are on NW 731 SP7 so we already have this report. This means we can go ahead with implementing the Z report from 1734333 and forget about the other note. Have I comprehended it correctly

Self programmed pre- and post trigger

Hello,
I am planning a measurement system and search some ideas for programming how to realize it.
I have an older NI PCI-6024E and want to measure 8 voltage signals with 2 kHz. When task is started it should run some hours without task stop.
Every 2000th sample (= every second), I want to store this sample (all 8 voltages) into a continuous file with printf.
For this I do not need the sampling rate of 2 kHz, 1 Hz would be enough but I want to do more:
Every time when voltage_1 increases over 1.1 V, I want to store all data – and 100 samples before – with 2 kHz into an other file till voltage_1 decreases under 0.9 V – and 100 samples after –. It will be like a self programmed pre- and post trigger with continious running measurement task.
I think I can work with an fifo-buffer (double fifo[10000 samples][8 channels]) but do not know how to do this on a smart way ;-)
Do you have any ideas how to mange it?
chemph

Hi Chemph,
since you have to use a DAQmx task to realize the data acqisition you can not change the sampling rate when the task is acquiring data. So I think the idea you mentioned is quite good.
You can implement a lossy queue so samples are deleted when they are not needed anymore.
For the logging you can keep keep over 100 samples in the queue and look for the 101st sample if it fits the rage you want. Then dequeue all elements from the queue and save them into a file. Afterwards save all elements in the queue until you find a value that does not match your requirements. Them you save another 100 samples and then continue from the beginning. I guess the file writing can be implemented in a state machine that represents the modi you want to save the measurement data.
I hope, this helps you with the concept.

Melanie

Standard procedure pre and post BW SPS?

Dear Guru,
I have looked around but not able to find a good answer on a standard procedure/common practice as one implement BW support pack. After we implemented SPS21 in our production system this past weekend, we had endless data load issues but didn't happen in our test or QA system. I think I need a better list of what to do pre and post SPS.
Please share your experience on implementing BI support pack. What do you do pre and post SPS?
Many thanks in advance.

Hi Bhima,
look at http://help.sap.com/saphelp_erp2004/helpdata/en/13/18601823c6ff4daa0bb05b4cded814/content.htm
In the Time of Calculation field (inside BEx formula properties), you can choose whether the formula is calculated After Aggregation or Before Aggregation.

Pre and post sql

Hi xperts,
what is the functionality of Pre SQL and Post SQL in source Qualifier Transformation??
Thanks,

Hi,
Pre SQL is the sql statement to be executed before perfoming the mappings on the target table and post is to be executed after performing the tasks.
post sql is that if any errors occur we can send an email or write logs to know the error.

Merging Itunes folders pre and post computer crash

I need to figure out how to merge my itunes folder pre-hard drive crash (i was able to retrieve my itunes folder) and post hard drive crash, then I need to put the merged file on my external hard drive or on my mac. Itunes is currently taking of 1/2 of the hard drive space on my pc (40 GB), so it needs to be moved.

Pre and Post test Questions

I have a project that requires a pre-test, post-test and
knowledge reviews throughout the course. I have created 10 question
slides (I did not use question pools). I am having two issues occur
within the course. First I do not want to track or score the
pre-test questions or the questions embedded within the course what
I will refer to as Knowledge reviews.
I do want the user to go through and receive feedback on each
question answered incorrectly but I do not want a score to be
collected/tracked or tallied as part of the sum total for the
course. The post-test questions need to be the only tracked/scored
questions with that value being submitted to the LMS.
Currently all the questions are being tallied in the course.
(i.e test results show 30 questions with a score when there should
only be 10). What is the best way to include mutiple questions
within my course (as pre-test and Knowledge reviews) but not have a
score tracked until the user takes a post test.
To correct this should I change the pre-test and knowledge
reviews to a survey type question? Or should I leave the question
as graded but set the point value to 0. I inially left the pre-test
and knowldge reviews as graded questions but I deselected Report
Answers under the reporting tab thinking this would prevent the
passing of a score, which is not the case.
If anyone can offer some advice or point me to some
documentaiton that discusses this I would greatly appreciate any
help.
The second issue I have is with the progress indicator within
the course. Is there a way to revmove this from the quesiton pages.
My client does not want to see this indicator. The current work
around I am using is to reduce the font size of the indicator to
5pt, setting the font color to match my background and then
positioning the indicator in a set loation on the page. While this
workaround works I would like to remove it in total if possible.
Thanks in advance,

The first part sounds very weird. I just made a project which
included knowledge checks in the middle of the course and they are
not tracked in the final test. I used Graded questions in my course
and I initially set the score per question to 0 points. After I
found out that they were counted in the question total I removed
the reporting for each of the questions. Now the points are not
being counted and also the questions are not being counted in the
final assesment - I just have the 6 questions out of 6 in the
post-test even though I have 4 knowledge checks inside the course
it self.
Try and click F9 to open up the advanced interaction panel
and make sure that the answers are not being reported. I know it's
obvious, but sometimes Captivate does some weird things.
As for your second question regarding the progress indicator
you can remove that by going to Quiz - Quiz Preferences - Settings
and then unchecking the box "Show Progress".
Best regards,
Michael

Difference between Pre and Post Incrementing a variable

I have a problem understanding the nuances between i++ and ++i.
I have run several loops and changed the position of the "++". I noticed that sometimes the out put differs and sometimes the output remains the same.
Is there a rule of thumb as to whether a variable show be post or pre incremented?
Thanks

Thank you all.
After I asked the question, I did a little research and found this (from JGuru shortcourse):
Note that x++ and ++x are equivalent in standalone contexts where the only task is to increment a variable by one,that is, contexts where the ultimate evaluation is ignored:
int x = 4;
x++; // same effect as ++x
System.out.println("x = " + x);
This code produces the output:
x = 5;
The next part after this is:
In the following context, the placement of the increment operator is important:
int x = 4;
int y = x++;
int z = ++x;
System.out.println(
"x = " + x + " y = " + y + " z = " + z);
This code produces the output:
x = 6 y = 4 z = 6
======================================================================
I thought the out put would be x = 4, y = 6, z = 4.
I totally lost! How do I interpet this correctly?

Pre and post-upgrade tasks in BW for Upgrading R/3 4.6c to mySAP ECC 5.0

We are currently in the process of migrating our R/3 4.6c System to mySAP ECC 5.0.
We would appreciate if anyone could provide the major and minor
Changes / impacts / measures, to be taken in BW side.
<u><b>Questions:</b></u>
1. What are the major impacts on the extractors, mainly delta?
2. Do we need to activate all the datasource immaterial of its status?
3. Steps to be taken for Unicode conversion
4. Routines and structure change if any?
5. Is there any change in DDIC objects?
6. Any old methods that can be replaced by new methods? (for better performance e.g, LIS was replaced by LO)
7. Changes in the database.
8. Anyother issues
Any relevant document will be helpful.
Thanks & Regards
Chandran Ganesan

It depends on what you are taking about: functional or Technical.
Tehcnially, after the upgrade you should make sure all the PI are working fine. The other things (i.e. extract)should be able keep the same. Unless you want to take advantage of the new WAS640 functionaity.
If you plan to migrate your BW system into ECC 5.0, you might have long way to go.
Also, depends on your BW release. If it's BW 3.1 or below, you might need to upgrade by end of this year anyway.

Checking pre and post conditions for a method

if precondition is satisfied then method executes
after executing
we need to check post conditions
i used java.lang.reflect
to get informatio of fields , parameter types (for methods) etc.
so after executing the method i.e after coming out can we access the latest values for checking the post condition ?

Ok, stop posting the same question, please. This is the 3rd one. I gave you an answer here: http://forum.java.sun.com/thread.jspa?threadID=690687
Please continue there.
