[SOLVED]handy compress function similar to extract in Core Utilities?

Hi!
I was wondering if there is a similar, easy, compress-function to be added to .basrc, like the the extract function at:
https://wiki.archlinux.org/index.php/Core_Utilities
Would be cool to just write:
compress archive.tar.gz [files]
compress archive.zip [files]
Maybe I should learn some bash scripting?

Can we implement the functionality similar to ROW_NUMBER() in generic/common way for all databases using SQL ?

In my project,i am allowing user to select database of his choice from given options & i need to write queries considering
all these optional databases. So as per my one of requirement,is there any way to achieve generic functionality similar to ROW_NUMBER() in MSSQL ?

First run this and check the db version
SELECT @@VERSION
EXEC sp_dbcmptlevel 'db name'
If version is above 2012 and compatibility level is above 80 ROW_NUMBER will work.
Otherwise you need to use this

Function Module not extracting records when InfoPackaged is executed

Hi,
I'm using a Function module for extracting data. The DataSource is working fine in RSA3 with a selection criteria. But when i schedule the infopackage with the same selections in the data selection tab, Its not getting me any records into BW. In the Details Tab i get the message "Error occurred in the data selection" . I guess there is a problem with the data selection. Pasted below is the code i'm using for extraction. Can anyone please let me know if there is any issue with the code.
Also how do we pass on the value of I_MAXSIZE into the function module, the remaining parameters get the values from BW. And can anyone please explain me the concept of the "s_counter_datapakid" and when it should be incremented and where it should be located in the code?
Thanks,

Help with compress function--file sizes not substantially reduced

I've tried to use the compress function (right click "compress" or Finder/File/Compress) a few times on files from a variety of different programs. While this results in creating a zip file, the file size is not substantially reduced (e.g., from 43.4 MB to 42.9 MB). Is there a way to change how much a file is compressed?
Thanks in advance for your help.
Eric

Not all material is very compressible. Text files and word processor documents usually compress very well. Photos and movies don't compress much if at all due to the nature of their structure (in some cases, using a general-purpose compressor can actually make a file larger). So it will depend on what it is you're compressing.

Creating BW Function module to extract R3 Function module data.

Could you tell me how to create a BW Function Module to Extract data from R/3 Function module?.
Also, the BW function module needs to pass a date/time filter to R/3 function module basis which the R/3 function module passes the date/time restricted data to BW function module.
Thanks,
Gautam

You will have to create a function module in R/3 and then call the same in BW using the RFC call function option.
Please do not raise separate threads for each question - you have asked the same question in another post of yours..

Does Numbers have a Data Analysis function similar to "Goal Seek" in Excel?

Does Apple's Numbers application have a Data Analysis function similar to the "Goal Seek" function in Excel?

No, Numbers doesn't have Goal Seek or anything like it.
You can set up Slider controls to facilitate playing with key variables in your expressions, but Numbers doesn't have any capability to make the adjustments itself.

Functionality similar to the Performance assistant box.

Hello All,
I am searching for a functionality similar to the Performance assistant box , with the links to go to other pages /transactions/ websites etc. I have to give a popup wit information when the user clicks on a button. This box should be similar to the performance assistant which we get on pressing F1 on any field.
Do we have any such functionality ?
Thanks,
Ketan Joglekar

Hi Ketan,
If you are creating a module pool,
U can use the Process On-Help event of Screens.
Like Proces on-Value is process on F4, Process on-Help is prrocess on F1.
U can code a module which will display a document created in SE61 which is same as the one u look at in Performance assistant.
Within the module, u can call a function module that displays this document.
So ur code will look similar to this:
PROCESS ON HELP-REQUEST.
field <field-name> module <module-name>.
within the module call FM 'HELP_OBJECT_SHOW'.
Pass DOKCLASS as TX (General Text)
DOKLANGU as sy-langu (logon language)
DOKNAME -> the name of document u created in SE61.
When u hit F1 on the field <field-name>, the document will be displayed
Regards,
Mahesh.

Simple String Compression Functions

Hi all !
I need two simple String compression functions, like
String compress(String what)
and
String decompress(String what)
myString.equals(decompress(compress(myString)))
should result in true.
Primarily I want to encode some plain text Strings so they are not too easy to read, and compression would be a nice feature here.
I already tried the util.zip package, but that one seems to need streams, I simply need Strings.
Any ideas ??
thx
Skippy

It does not do any compression, in fact it does
expansion to better encrypt the string (about 50%).How does that work? You want encryption to
decrease entropy.Why in the world do you say that, pjt33? What a very odd statement indeed. I sure hope you don't work in security, or I do hope you work in security if I'm a bad guy, or a competitor.
Let's say you had a 6-character string you wanted to encrypt.
Well, if you didn't increase the entropy, any 6-character plaintext string would have a 6-character encoded equivalent. And if you decreased entropy (e.g. coding the most commonly used words to shorter strings,) it gets even easier to decrypt.
Presumably there would be no hash collisions, after all, you want this to be reversible.
Hash collisions decrease entropy too, and, by doing so, make it easier to find a plaintext string that happens to hash to a certain value. This is a Bad Thing.
Now, to decode this, the Bad Guy only has to consider the set of 6-character strings and their hash values. You could even precalculate all of the common dictionary words, and everything with common letters and punctuation, making decryption virtually instantaneous. Especially if you had decreased the entropy in the signal, making fewer things I had to try.
But somebody who increased the entropy of their signal by adding random bits and increasing the encrypted size of the message to, say, 64 characters, would make it a lot harder to decrypt.
The ideal encryption system is pure noise; pure randomized entropy. An indecipherable wall of 0 and 1 seemingly generated at random. Statistical methods can't be used against it; nothing can be deciphered from it; it's as decipherable and meaningless as radio hiss. Now that's encryption!

Hi Baljit,
This is a dangerous way of extracting your data.
I am not surprised that it has become an endless loop.
You have to use the cursor and the fetch statement and after the fetch statement you have to use a subreturncode
to wonder if the fetch statement did get any data.
if not use the folowing statements.
close cursor s_cursor.
raise no_more_data.
In your situation the select statement will start every time from the first record in the table ysales because you don't use the cursor. By using the cursor and the fetch statement, the fetch statement will start from the cursor everytime it calls the function module.
I guess this function module is part of an endless loop and will be exited at the moment that the function module returns with raise no_more_data. (in other words, the cursor is at the last record of the table ysales, so no more records will be found)
Hope this will help

i made user to set the tasks and tasks are stored in files. now say if the user sets a task on 1st jan 07 10 am. the user should be reminded via mail (like birthday reminder mails) about the event/task that he set.
I am not known as to how can I develop code to identify the date and time set on a task and send a reminder mail to user.
I am using this feature in my webmail application and that made me to post my question here.
If i am not in the right area, I regret.

Jobs to run the function modules to extract the generic extarctors

Gurus,
I have a Datasource 'ZCMS_PP_TRAN' with extract structure 'ZBW_ST_CMSD_PP'. The extract structure is populated using the function module Z_BW_GET_CMSD_PP.
But how do I schedule this FM or in general, are they run using std programs?
Thanks,
Simmi

Hi Simmi,
what ever it may be the DS(i mean Business Content DS, Generic DS).... these will extract the Data using Dynamic Function Calls(not always). Comming to Generic DS using FM, this will be called using Dynamic Function Module.
In RSA3 or while extracting data from BW, you will pass request number, Update Mode, debugging option, selection fields, BW source System ID, DS Name.
Based on these details system will extract the underlying extract structure and function module(or table/view/infoset).
No job(Job created from BW while extracting data in the source system BI_requestid) created for Generic DS while extracting data in SAP.
For Queue Delta, Background job will be created, it will move the data to Delta Queue.
i will update the thread with related function modules. Try to debugg in RSA3, you could find all the information.
all the best.

Auto Replace functionality similar to TOAD

I've played with Raptor 804 for a few hours now. Only a couple things keeping me from being able to move (comfortably) to Raptor from Toad at this point.
1) Bind Variables not remembering values if I run queries repetively. Other posts address that issue
2) The other is Toad's Auto Replace feature. I have huge library built where I can type in a few letters and when I hit the space bar (or other set characters) the characters are replaced with something else. ie...I type "srf" and I get "select a.*, a.rowid from" or I type "hca" and I get the table name "ar.hz_cust_accounts" etc....
Because I've got so many auto replace keystrokes saved I am able to type out ad-hoc queries in a hurry. I see Raptor has an Accelerators option under Preferences but that doesn't do quite what I want.
3) Other very nice to have (because of the way I work) is the Named Sql options that is available in Toad. Basically instead of having a bunch of standard queries that I use all the time saved into files, I've got them saved in my Named Sql's in Toad so I can quicly pop them up (with a shortcut keystroke Ctrl-N) and then click on the one similar to the Sql History window. In conjunction with the bind variable functionality listed in item 1, it helps me investigate things very quickly when researching issues.
Initial results on Raptor look good. I'm looking forward to it improving to the point where I can ditch Toad (which I've lost all faith in).

1) try the new build it's in there
2) This will have to wait till 1.1 however I agree for no other reason then fixing my select * form dual.
3) Would key shortcuts and the ability to manage the snippets work ( again in 1.1)

Function Module to extract char values for a matl variant

Experts,
Looking for a Function Module with which I can extract the Char value for a specific characteristic on my material variant. So, the class type is 300 & I would like to pass this material (variant) as an input in order to retrieve the value for the specific characteristic (which will be unique to this variant)
Any one, an idea?
thanks

Ok, I found what I needed. For everyone's benefit, herez what I found:
1. every application/object in the SAP side which uses the configuration has a unique Internal Object #. For material variants, Sales Documents, Prodn Ord headers & components, so on so forth.
2. In the system the fields CUOBF, CUOBJ carry these Internal Obj #'s. For the sake of getting the material variant char & values I found the func module VC_I_GET_CONFIGURATION, where the input could be the Int Obj # from the MARA or the one from VBAP, based on the need.
Thanks

Functional module on extracting character and numeric value

Dear All,
I have one file which type is character. It contains alphanumeric values. (Ex. 500G & 7KG etc.) I want to extract numeric and characteristic values.
There is no pre-defined no. of digits means actual value may have 5, 6 7.. digits.
Ex.
1) Actual Value: 8975G
Target Value: : 8975
2) Actual Value: 500KG
Target Value: 500000
Is there any standard function are available for this task?
