Reg: Unicode- Coverage Analyzer- (SCOV)

Hi
Can any one tell me how we can use the Coverage Analyzer (Transaction SCOV)as a tool for Unicode enabling. What are the sequence of steps that are to be followed.
Any Information, Documentation, Links, or examples that elucidates the same are highly solicited.
Thank you in anticipation.
Regards,
Sravan.

Hi,
I haven't used SCOV much.
In SCOV, 'global view' gives you a set of figures and graphical representation of system performance data. One of these graphs show the unicode-percentange of all programs that are unicode-enabled(one axis is time (month) and other axis represents percentage of programs that are unicode enabled). This is just to see how many programs have been unicode-enabled in the system. As long as you are not 100%, there is work to be done.
To force unicode-enabling (there may be programs which are unicode compliant but have not been set to unicode), you can check the profile parameter abap/unicode_check to enforce unicode syntax checks. (This has nothing to do with SCOV per se).
Now, how best to use SCOV when an object is being unicode-enabled and you need to make sure it is working fine?
After unicode-enabling the program you need to test it to make sure it works. But after running one or more tests successfully, how do you know whether all lines of code in the program have been covered in the tests?
SCOV can give you information whether all blocks of the code has been tested or not. If all blocks of a program/object have been tested after unicode-enabling (as reported in SCOV) then you can assume your testing to be complete. If on the other hand some blocks (let us say cetain subroutines in the program) have not been executed, you can see this in the detailed view in SCOV, and accordingly run other tests to ensure that this code is tested.
I am sorry I can not give you a step by step for this, if you post your mail-id, I can probably mail you a document which talks about this in a little (not much) detail.
cheers,

Using SCOV ( Coverage Analyzer) in Production

Hi,
Our organization would like to start using SCOV ( Coverage Analyzer ) on our Production system. From owr understanding, when the main switch is turned on, there are several jobs sheduled that compile all programs. This step should be very expensive in terms of system resources and when it is done on Production system - it could be crutual. My question: is there any way to make this step easier in terms of performance overhead? Maybe to run it on each Application Server seperately?
In general I would like to know if anyone has experience running SCOV on production system. Is there any effect on performance except the first compilcation step?
Thanks in advance,
Anna Lifshits-Agmon

you might want to take a look at OSS note 626215. We recently ran this overnight in our development system and it fell over, running out of tablespace in certain areas. Next time we ran it, we used the note, extended the necessary tablespaces and made sure we kept an eye on it. It took a day to run in our development system as it generates every program on the system. We've not yet tried it on Production.

Unicode Coverage analyzer

Hi,
Can somebody please help me with how to use coverage analyzer?
Thanks,
Yogita

Hello
The Coverage Analyzer is a tool for entering the number of calls for processing blocks and executable programs separately according to periods, users and functional areas. The processing blocks and executable programs together with their keywords are shown in the following table:
Unit
Keyword
Procedures
form, function, method
Dialog modules
module
Event blocks
at line selection, at pf<xx>, at selection screen, at user command, end of page, end of selection, get, get late, initialization, start-of-selection, top-of-page
Programs
program, report
The Coverage Analyzer is, therefore, a function for monitoring the system-wide execution of ABAP programs. It also
enables the success of test activities to be assessed for quality checks,
provides an overview of the use of programs for development purposes.
The transaction is SCOV.

No colouring in Statement Coverage

Hello,
Im using EHP6 for SAP ERP 6.0.
In the Unit Tests there are some Codes that arent highlighted in red or green in the coverage Analyzer.
Does anybody know why this is so? And if there´s a Workaround for this?
The Codes have a lot of comments in it, i´ve seen code without comments and everything runs finde (red/green highlighting).
Is it neccessary to clean the Code from comments?
Best regards,
Timo

Hi Randolf,
Yes i know about that. I can´t give you a Screenshot for Security Reasons.
What i´ve found so far is, that if i let the mouse curso for about 1500 ms on a line, then a popup near the cursor describes how often this code row has actually been reached and how often it was reached during the whole unit test. So it seems to me, that the process of gathering information about
how often a line of code during the unit test was reached, runs as usual.
The only annoying thing is, that this information isn´t painted in red/green on the code.
So for security reasons, i can describe the code as pseudo as follows:
- Public instance method test1
METHOD test1.
TYPES: BEGIN OF test_type,
                         amount TYPE i,
                         percentage TYPE internal_percentage,
               END OF test_type.
DATA:
     some Variables here....
FIELD SYMBOLS:
     some Field Symbols here...
BEGIN OF METHOD LOGIC
*SOME COMMENT HERE
ANOTHER MEHTOD LOGIC
"SOME INLINE COMMENT HERE
"THE COMMENT NOW GOES ON IN THIS LINE
MORE METHOD LOGIC
*ANOTHER COMMENT WAS WRITTEN HERE
MODIFY SOME STRUCTUR "This is the Structur
*HERE WAS THE OLD MODIFY OF STRUCTURE
*YET ANOTHER COMMENT
CALL FUNCTION 'ROUND'
ENDMETHOD.
I hope this helps for any suggestions.

New Features in 4.7 version

Hi Gurus,
In my current project i will be working on SAP 4.7 version and wanted to know what all new features were added from Abap perspective.
I did go though relaease notes but it was not realy helpful. I did saw new monitoring tools like
1. Coverage analyzer
2. code inspector
3. Runtime monitor
and must say are realy helpful for developers and testers.
Gurus are there are new features/commands/tools added in 4.7 version which i should be aware of.
Thanks in advance.
Gurjeet.

Hi,
Thanks for your reply, but most of these features are not available in SAP 4.7 version.
Like Memory monitor, assert command, enhanced debugger, shared memory are not available in 4.7 version.
I wish i could use them but unfortunately my current version of SAP doesn't support it. Can you please provide information on 4.7 version.
Thanks again.
Regards,
Gurjeet

Before calling an external program, check if the program is allready open

I need to call an external program to print some labels, so i will use function WS_EXECUTE or the new one DSVAS_DOC_WS_EXECUTE_50 to call my program, but the problem that i have is:
when I call this function, the program open a small window, and if i have to call it again, it will open another window, and so on... obviously this is not a good solution.
Is there any one how knows how can i close the program, of perhaps it is enough if there is some way to know if the program is already open.
Many thanks in advance,
Miriam

Hi
you can use the ABAP Coverage Analyzer.
OR
This is a function module we use to limit the execution of a program to one instance at a time.
DATA: PRG LIKE INDX-SRTFD. PRG = SY-CPROG.
CALL FUNCTION 'ENQUEUE_ESINDX'
EXPORTING RELID = 'ZZ'
SRTFD = PRG
SRTF2 = 0
EXCEPTIONS FOREIGN_LOCK = 1
SYSTEM_FAILURE = 2.
IF SY-SUBRC NE 0.
FORMAT COLOR COL_NEGATIVE INVERSE ON.
WRITE: / 'ERROR: Program Is Already Running'.
WRITE: / 'Program', PRG, 'has been stopped. Rerun in 1 minute.'.
STOP.
ELSE.
WRITE: / 'OK ',PRG.
ENDIF.

Question about bw transport (3)

Hello Gurus,
    will you please answer my following questions:
      (1) can I transport everything in the AWB transport connection ? is there
            any exception?
      (2) what is Standard Transport System (automatic transport connection) ?
      (3) what does object collector mean ?
      (4) when should we apply "object changeability" function in AWB transport
           connect ?
Many thanks,
Frank Zhang

Hi.....
1) can I transport everything in the AWB transport connection ? is there
any exception?
Yes.........In the AWB transport connection u can transport all the BW objects.............U can go here through RSA1 ..........or u can also use the tcode : RSOR.......Here u can select Object types from the left side window..........In the right side click on the select objects..............then collect manuaaly all the objects which u want to transfer............
2) what is Standard Transport System (automatic transport connection) ?
Check this..........
http://help.sap.com/saphelp_nw04/helpdata/en/94/d4943b00ce6622e10000000a114084/frameset.htm
3) what does object collector mean ?
Using object collectors, you can create a set of objects. For example:
·        By loading the objects from files
·        From object lists of programs such as Where-Used List, Coverage Analyzer, or Runtime Analysis
4) when should we apply "object changeability" function in AWB transport
connect ?
Sometimes it is useful...........and also required to make changes in Production Box........... mainly in day to day operations......... such as Activating Objects , fixing data loads,Changing Starting time of a process chain,new quiries to be created.........
Check this........

Call statistics for customer functions (CMOD)

Hi experts,
I wonder, whether R/3 4.6C provides an option to generate a call statistics for customer functions (w/o adding additional logging code in the ZX-includes).
This would be beneficial to identify customer functions called frequently (and to check/improve the performance of these subsequently).
I am aware of a similar feature for BAdIs as well as the coverage analyzer (in NW'04s).
Regards
Thomas

Hello Thomas
On a 4.6c release I would use the following approach:
(1) Identify the transactions which pass user-exits
(2) Analyze transaction log

Uwe

Inputs required on SCOV tool

Hi All,
U guys must be aware of the SCOV tool, coverage analyzer used to keep a check on quality of code written.
We need to bring this tool into practice in our project to increase the quality of code delivered.
I found that it requires unit test cases to be implemented in the code itself using the class cl_aunit_assert and its methods.
We have not been in practice of writing unit test cases, can someone help me with that.
Sample unit test cases will be helpfull.
Also, I tried implementing the test class with simple methods along with the development.
On executing the report with coverage, the unit test cases run successfully but in scov tool still the status remains red with coverage fields as blank.
Please provide me some inputs to use this tool effectively.
Regards,
Shreya

you should use method IN_UPDATE so you are sure it is executed after the data have been saved

SCOV - how to setup?

We are trying to set up SCOV (Coverage Analyzer) to assist us in finding testing % of programs.
Using it for the first time
There are some settings that we need to do:
- Data Collection Background Server
- Summarization Background server.
What should be entered in these 2 fields? Can they point to the same server in which I am running the transaction?
Also I read in the documentation following:
A program is regarded as tested if the following conditions are fulfilled:
       1.      Count1 Absolute Value      > 0
       2.      Count2 Absolute Value      > 0
       3.      RABAX2 Absolute Value    = 0
       4.      Unicode Check           = 1
Where are these fields Count1, Count2, RABAX2?
Thanks in adv.

Hi Gurus.
Any replies to this?
I am not sure how to use the Unicode thing also. The doc says that Cov Analyzer can help to let us know how much the system is "unicode ready".
Another thing - I tried to set up SCOV. But in the graphical view, my graph does not change on selecting different nodes.
Also, how to use the test groups?
Any pointers welcome please.

Unicode programs testing

Hi ,
I have question about unicode UCCHECK programs testing.
Do we need to do testing after UCCHECK errors are fixed and Unicode flag is set in SE38 to check the functionality and runtime errors in Non-Unicode system?
Or
Just do the testing in Unicode system after conversion?
For what volume of programs , we should use transaction SCOV for test coverage?
Thanks!

Hello Yogita
If you removed all Unicode errors and set the flag this just means your program objects run on a Unicode system - either right or wrong
Therefore, you must test on a Unicode system. See also: Unicode Compliant: Sample test plan
I would recommend to use transaction SCOV even with a small number of program objects. This way you can make your experiences with the coverage analyzer and you are prepared for "big" development tasks.
Regards
Uwe

Performance Transactions
