What is the PXI-7854R Digital IO Type and is it User Setable.

Are the Digital Outputs on the 785x cards Line Driver, Open Collector, or Push-Pull Outputs?
Specifically the card I am working with is PXI-7854R.
Here is my basic question, but notice that the R-series cards are missing.

Also, does the card have the capability to select which type of DIO is implemented?
Here is a write up I found doing this via DAQmx, which I of course don't use for this card.

The type of digital output can be manipulated through your FPGA code.
For example, you can set the "Output enable" to true, then toggle the output value between true and false to make the card source and sink accordingly.
You can achieve an open drain configuration by setting the output value to false, then toggle the "Output enable" between true and false. In the true setting, it turns on the false output and sinks current. In the false setting, the output is disabled and set to a high impedance.
You can have an active-high, high impedance low configuration by setting the output value to true and toggling "Output enable" between true and false. In this setting, the true output setting will source current when output enable is true, and when output enable is false, it will be set to a high impedance.

What is the difference between /6** wage types and /7** wgae types

Hi All,
Can you please tell me the difference between /6 & /7 wage types
and in what scenario /6 and /7 wage type amounts differ
Thanks in advance
Krishna

- /6XX - Gross wages less pre-tax deduction. For example, if salary is $1,000 and the 401(k) deduction is $200,/6xx will be $800. SAP passes this amount to BSI for tax calculation. (/EXX - Tip income processing)
- /7XX - Reportable taxable amount calculated by BSI. If ceilings on taxable amounts exist and are exceeded, BSI will return a reportable taxable amount of zero. (/FXX - tip income processing).

What are the different values available for type attribute

Hi,
    I am working with IDOC to Stored Procedure. For each field we need to give the values for 'isInput' and 'type' attributes. I need to pass values for 'datetime' and 'numeric' fields. What are the list of values availabIe for 'type' attribute. I know only about 'CHAR' attribute.
     Can anybody please tell me what all the values availabe for attribute 'type'. I am facing this problem while giving the value for type attribute.
Thanks in Advance,

While defining a columnar table, what is the purpose of column store type

Hi folks
I have two questions related to columnar table definition.
1. What is the purpose of column store type.
While defining a columnar table, what is the purpose of column store type (STRING ,CS_FIXEDSTRING,CS_INT etc) , when I define a table using the UI I see that the column is showing STRING but when I goto EXPORT SQL it does not show. Is this mandatory or optional ?
2.VARCHAR Vs. CHAR - In the UI when I create the table I do not see the CHAR option , but I do see lot of discussion where people are using CHAR for defining the columnar table. Not sure why UI dropdown does not show it. I also read that we should avoid using VARCHAR as those columns are not compressed, is that true, I thought the column store gives compression for all the columns. Are there certain columns which cannot be compressed .
Please let me know where I can find more information about these two questions.
Poonam

Hi Poonam
the CS_-data types are the data types that are used internally in the column store. They can be supplied but it is not at all required or recommended to do so.
SAP HANA will automatically use the correct CS_-data type for every SQL data type in your table definitions.
To be very clear about this: don't use the CS_-data types directly. Just stick to the SQL data types.
Concerning VARCHAR vs CHAR: fixed character data types are not supported anymore and don't show up anymore in the documentation.
I have no idea why you believe that VARCHAR columns are not compressed but this is just a myth.
create column table charcompr (fchar char(20), vchar varchar(20));
insert into charcompr (
    select lpad ('x', to_int (rand()*20), 'y'), null from objects cross join objects);
-- same data into both columns
update charcompr set vchar = fchar;
-- perform the delta merge and force a compression optimization
merge delta of charcompr;
update charcompr with parameters ('OPTIMIZE_COMPRESSION' ='FORCE');
-- check the memory requirements
select COLUMN_NAME, MEMORY_SIZE_IN_TOTAL, UNCOMPRESSED_SIZE, COUNT, DISTINCT_COUNT, COMPRESSION_TYPE
from m_cs_columns where table_name ='CHARCOMPR'
COLUMN_NAME    MEMORY_SIZE_IN_TOTAL    UNCOMPRESSED_SIZE   COUNT   DISTINCT_COUNT COMPRESSION_TYPE
FCHAR       3661                    70285738            6692569 20              RLE
VCHAR       3661                    70285738            6692569 20              RLE
We see: compression and memory requirements are the same for both fixed and variable character sizes.

What is the table for checking billing types assigned to sales orders

Hi Folks,
Good morning!
Could you please help me how to check the billing types assigned to sales documents.
What is the table to see billing types assigned to sales documents.
Regards,
Sarath

Hello Sarath,
As mentioned by Siva in the above the table name is TVAK but if you are a functional guy then you should go by the functional assignment.We are assigning the default billing type in Tcode= VOV8.
All sales document control you can find over here.
Needless to mention this Billing type you are assigning over here is auto proposed during billing in VF01. But you have option to choose another billing type in VF01 itself considering you have maintained the Copy Control for that.
Thanks,

What is the maximal line length of type any internal table

Dear all,
who can tell me what is the maximal line length of type any internal table.
Thanks!

There is no limit to the record length of an internal table.
There is overall memory limit for every program (as setup by your basis). So, depending on the width of the ITAB, the number of records in ITAB is limited by the assigned memory.

What is the maximum number of Call Types, Skill Groups and Campaigns created in ICM 8.0.1 and 8.0.3

Hi All,
What is the maximum number of Call Types, Skill Groups and Campaigns created in ICM 8.0.1 and 8.0.3?
In which the above requested information will be available??

Oh I see. So I guess what you are saying is that is
Director's way of compressing vector numbers. Also, as to what you
were saying about the number 3000 is sure not the limit for vector
units, I think I was just jumping the gun considering that I only
glanced at the script error, and then clicked on the debug button
to see where the error happened. Then once I looked at the varibles
in the varible window, I saw these weird numbers with the e3 at the
end of them, and I just thought that it could not add the vectors
together with the e3 at the end of each vector unit. However, to
make a long story short, I detached the script and reattached it
which did no create the error again, and I learned that Director
can add vector units together that have an e3 at the end of each
vector unit. So thanks for clarifying what the e3 means.

What is the use of Framework Order type purchase order ?

what is the use of Framework Order type purchase order ? How it differs from other regular type?

Hi,
The document type of Framework Order is "FO" .The regular use of document type for purchase order is "NB".The use of "NB" and "FO" Document type in Purchase order to differentiate the how your material behave or to have different different purchasing document.
Example:Document type "NB" have to the process like Goods Receipt,inoice receipt & payment .In the case of Document type "FO" no Goods Receipt required but IR and payment have to be done."FO"(Framework Order) only deals with low value item with validity period as well as the limits on value/price.
Hope helpful to you and then reward.

What is the use of Digital Signature in export release build for AIR applications

hi Freinds..
what is the use of digital signature identity when we release build?

Well obviously it is an Ant build.
It looks to just compile/build a web application into a war so you can deploy it where you want to.
You don't need to edit it every time you are making a new page. It should work for any generic struts web application laid out in the fashion it expects.

Hi. Thanks.
I loan out CD's and records to friend but to my knowledge they just use it to listen to, they then do the same for me.
So if I get this correctly, downloading music from iTunes is like downloading Apps in that it does not matter which device I load it onto? Or is there a hiccup here in terms of having a laptop, desktop and iPhone? For instance my iPhone is synced up to my laptop (it used to be synced to the desktop) and I had/have to be very careful about making sure I transferred my Apps over to the laptop - using the iPhone I think - when I started syncing the device with the laptop. There was some risk of losing all the Apps if I did this correctly, no?
Is it the same with music downloads? should I only download from my iPhone/laptop combo or an iPhone/desktop combo? I mean, I actually find it /more/ convenient to do things on the desktop machine but this makes it hard to sync with the laptop if I am traveling so I now only download APPS to the laptop machine.
Does this question make sense? Do I need to use one computer or another for this?
Also, in terms of my other burned CD Roms (that are now digital), I assume these are non DRM and I can move them laptop to desktop to iPhone and back with no issues whatsoever?
I mean is there a difference in this respect between iTunes downloaded songs and ripped songs from my collection?
Thanks.
