Differrence between BPCA and Change Impact Testing in HP Quality Center?

Hi All,
Can some one help us with the differences between change impact analyser in SAP TAO and change impact testing in
HP quality center.
Please share some process documents regarding the same.
Regards,
Ujwal Kandimalla

Hi Ujwal,
The Business Process Change Analyser in Solution Manager compares a technical BOM (TBOM) that is maintained within a solution, or project, against a transport order that is maintained within a managed system. The TBOM is a listing of all technical objects, for example tables, programs etc, that are used by the managed system. BPCA checks the contents of the transport order against the TBOM. BPCA then highlights the objects in the TBOM that will be impacted when you import the transport order into production. From the BPCA you can directly create a Test Plan and select the test cases that will test the objects that will change.
SAP TAO inspects transactions to determine the technical information required to generate an automated test. TAO then creates scripting for HP Quick Test Pro test cases and can create business components in HP Quality Center that can be used to compose business process tests.
HP Change Impact Testing allows you to import changes from the SAP correction and transport system, analyse and identify the impact of changes, assess their risk and recommend which business processes to test.
There are some good presentations about BPCA and TAO and this one could give you the back ground info to the SAP solution: https://websmp104.sap-ag.de/~sapidb/011000358700000988132011E
Hope this helps,

What is the difference between task and change request?

Hi all
What is the difference between task and change request?
thanks all

Dear Ispit,
<a href="http://help.sap.com/saphelp_nw2004s/helpdata/en/19/3f5bf8a4b011d285090000e8a57770/content.htm">Request Types and Task Types</a>
<a href="http://help.sap.com/saphelp_sm32/helpdata/en/dd/cc86a571464559a2685a404397065b/content.htm">Change Transactions in Change Request Management</a>
For more information about the SAP Change and Transport System (CTS), visit the following link:
http://help.sap.com/saphelp_nw04/helpdata/en/57/38ddff4eb711d182bf0000e829fbfe/frameset.htm
Transport Request is generated in following scenarios:
1. Customizing Request - When doing or changing some customization.
2. WorkBench Request - When configuration is cross-client. Eg Generating new Table, making changes in access sequence, Abap development, etc.
Transport request is not generated for Master Data. For eg: Customer Master, Material Master, price master, etc.
Benefit of Transport Request:
SAP Landscape normally has 3- Tier system:
Development Server - Where customization takes place. Transport request is generated at this level & then first transported to Quality server for testing whether it meets the requirement or not. Once the requirement is met in Quality server then Request is transported from Development Server to Production Server (Actual / Live System)
Quality Server - Mainly useful for testing.
Production Server Actual / Live server, where the real transactions are created & posted.
Procedure to Release & Transport Request:
1. In development server, go to T.Code: SE10 & select the check box Modifiable & enter
2. In the next screen, you will see list of transport request created.
Note: Transport request consist of main request along with sub request. These sub request hold the object to be transported.
3. Expand the main request & you will be able to view the sub requests attached to main request.
4. First release the sub requests.
Note: To release the request, select the request ni & click on release request individually (Do not select release all request)
5. Next release main request.
6. Once the request is released sucessfully, imform the basis person to import the request to QA server.
or
If the authority is with you, through T.Code: STMS, select development server --> select request no & release to QA server. Here when it pops up client no, user id & password, maintain it of QA server & release the request to QA server.
Reward points if this is helpful.

Differrences between structure and table in data dictionary in ABAP?

What is the differrences between structure and table in data dictionary in ABAP?
are they same?

Tables :
1. The place where the data is stored so that you can retrieve at any time.
2. There can be more than one record stored
Structures :
1. The data / info stays only during the runtime of the application and will not get stored at all during the run time ....
2. Only one record can be stored at the runtime .....
A structure forms the skeleton of the table.
A structure comprises components i.e., fields. Types are defined for the components A component can refer to an elementary type (via a data element or by directly specifying the data type and length in the structure definition), another structure or a table type. A structure can therefore be nested to any depth
Tables can be defined independently of the database in the ABAP Dictionary. The fields of the table are defined with their (database-independent) data types and lengths.
When the table is activated, a physical table definition is created in the database for the table definition stored in the ABAP Dictionary. The table definition is translated from the ABAP Dictionary to a definition of the particular database.

PLMD_AUDIT - Toggle between Display and Change - Important!!

Hello all,
I've a problem when I work on PLMD_AUDIT.
Pre-requisite for replicating the issue.
1> Change the settings in PLMD_AUDIT (a face like icon) to Display mode
When I run PLMD_AUDIT for an Audit with Action, it displays me the "Grouping" field and the "Involved Persons" tab values correctly.
But when I toggle from Display to Change, the value in "Grouping" and the "Involved Persons" tab vanishes.
Can you please check in your system and let me know if you also face this issue?
Thank you in advance,
Vaishnavi

Hello Keerthi,
Thanks for your reply.
Please follow the below mentioned steps.
1) Change your time zone to a different time zone other than the created time zone of the action.
say if action has been created in London time zone, change system zone to some other than London.
2) Change the Settings in PLMD_AUDIT tcode (face like icon) to Display
3) Open any audit WITH ACTION.
4) When you double click on Action inside the audit, the action will be opened in Display mode.
5) Now toggle between Display and Change.
6) Kindly check if the values in the "Grouping field" and BUPA roles in "Involved Persons" tab are present now after toggling?
Please let me know at the earliest.
Your assistance is highly appreciated in this regard.
Thanks in advance,
Vaishnavi

Diffenence between task and change request

What is the difference between task and change request? Is it possible to release a change request without releasing a task?

Tasks are a level under the change request. You can have multiple tasks under each change request. You can release a task without releasing the change request, but not vice versa.

Difference between Using and Changing

hi,
while defining subroutines, what is the exact difference between Using and Changing?
when we pass by reference we can use both and while passing using value we can use both + Value (VAR).
Then what is the exact difference between two?
Also, what is formal parameter?q
Moderator message - Please do not ask or answer basic questions - thread locked
Edited by: Rob Burbank on Dec 14, 2009 3:31 PM

Hi C`hinmay,
When a subroutine is called with "USING" you can make use of the value inside your subroutine but you cannot change the value. With CHANGING you can CHANGE the value too. Formal parameter is the PARAMETER NAME used while defining the interface of a Subroutine.

DIFFERRENCE BETWEEN CANVAS AND VIEWS

Hi,
Can any one tell me whats the differrence between Oracle Forms Canvas and Canvas View ? Coz the built-ins are differrent for canvas and view though they perform the samehting like FIND_CANVAS, FIND_VIEW .

Hi,
WebDynpro is a highly declarative, tool-based programming model. It minimizes platform-dependent "plumbing" code for building UIs and maximizes declarative metadata describing huge portions of a typical application in a platform-independent way.
Web Dynpro follows a "top-down" approach in order to consistently support multiple runtime platforms.
In Web Dynpro you just do drag & drop the UI components.
Portal components has followed a "bottom-up", programming-driven approach to Web development.
Webdynpro is used when requirements ask for a prototype using minimal time n effort.
Highly skilled programmers are not necessary to write a webdynpro application
It uses dynamic controls without reloading the page.
The Portal Development Kit (PDK) provides documentation and examples with source code to demonstrate how to develop portal applications and portal content for the SAP NetWeaver Portal using the SAP NetWeaver Developer Studio.
PDK includes coding examples on the following topics:
*Creating Portal Components and Portal Services
*Portal Profiles
*Resources
*Internationalization
*Portal Beans
*Page Builder
*EPCF
*Application Integrator
*Connector Framework
*Portal Navigation
*Object Based Navigation
*Transformation Service
*User Management
PDK is for deployment for portal application, has very good documentation of portal development, contains sample application, Java Docs for all the apis for portal and KM and plugins for eclipse(which you don't need if you are using NWDS). It is basically a nice help for developer along with an iviews for uploading par and testing them.
In EP 6.0 it is just business package that you import to your portal. This will then give a "java development" role in portal which can be assigned to users. The role will then create a tab called "Java Development" in the top navigation and click on it you can see all the contents underneath.

Any body explain me the differrence between BAPI and RFC

Hi gurues,
The main difference between rfc and bapi is calling the non sap system. Other than that what r the differrence . How sap modules works other machine without sap is installed.

The difference is not importat while you understand the concept.
I think, RFC is the protocol for calling functions from external systems in R/3.
I understand like BAPI a series of complet functions that SAP offers you for use and model a business use.
But if I need program a function that can be called for external system i would call it RFC_NAME, because is a unique function that makes a single task.
In other words, the difference i think is about work idea more than another thing.
RFC
A remote function call is a call to a function module running in a system different from the caller's. The remote function can also be called from within the same system (as a remote call).
RFC consists of two interfaces : A calling interface for ABAP Programs and a calling interface for Non-SAP programs.
The RFC Interface takes care of :-
Converting all parameter data to the representation needed in the remote system
Calling the communication routines needed to talk to the remote system.
Handling communications errors, and notifying the caller, if desired ( using EXCEPTIONS paramater of the CALL FUNCTION).
BAPI
BAPIs are standardized programming interfaces (methods) enabling external applications to access business processes and data in the R/3 System.
BAPIs provide stable and standardized methods to achieve seamless integration between the R/3 System and external applications, legacy systems and add-ons.
BAPIs are defined in the BOR(Business object repository) as methods of SAP business object types that carry out specific business functions.
BAPIs are implemented as RFC-enabled function modules and are created in the Function Builder of the ABAP Workbench.
The most critical difference btwn BAPI and FM is that BAPI can be wrapped in Business objects whereas RFC cant.
BAPI are RFC enabled function modules. the difference between RFc and BAPI are business objects. You create business objects and those are then registered in your BOR (Business Object Repository) which can be accessed outside the SAP system by using some other applications (Non-SAP) such as VB or JAVA. in this case u only specify the business object and its method from external system in BAPI there is no direct system call. while RFC are direct system call Some BAPIs provide basic functions and can be used for most SAP business object types. These BAPIs should be implemented the same for all business object types. Standardized BAPIs are easier to use and prevent users having to deal with a number of different BAPIs. Whenever possible, a standardized BAPI must be used in preference to an individual BAPI.
The following standardized BAPIs are provided:
Reading instances of SAP business objects
GetList ( ) With the BAPI GetList you can select a range of object key values, for example, company codes and material numbers.
The BAPI GetList() is a class method.
GetDetail() With the BAPI GetDetail() the details of an instance of a business object type are retrieved and returned to the calling program. The instance is identified via its key. The BAPI GetDetail() is an instance method. BAPIs that can create, change or delete instances of a business object type
The following BAPIs of the same object type have to be programmed so that they can be called several times within one transaction. For example, if, after sales order 1 has been created, a second sales order 2 is created in the same transaction, the second BAPI call must not affect the consistency of the sales order 2. After completing the transaction with a COMMIT WORK, both the orders are saved consistently in the database.
Create( ) and CreateFromData! ( )
The BAPIs Create() and CreateFromData() create an instance of an SAP business object type, for example, a purchase order. These BAPIs are class methods.
Change( )
The BAPI Change() changes an existing instance of an SAP business object type, for example, a purchase order. The BAPI Change () is an instance method.
Delete( ) and Undelete( ) The BAPI Delete() deletes an instance of an SAP business object type from the database or sets a deletion flag.
The BAPI Undelete() removes a deletion flag. These BAPIs are instance methods.
Cancel ( ) Unlike the BAPI Delete(), the BAPI Cancel() cancels an instance of a business object type. The instance to be cancelled remains in the database and an additional instance is created and this is the one that is actually canceled. The Cancel() BAPI is an instance method.
Add<subobject> ( ) and Remove<subobject> ( ) The BAPI Add<subobject> adds a subobject to an existing object inst! ance and the BAPI and Remove<subobject> removes a subobject from an object instance. These BAPIs are instance methods.

Why is the difference in execution speed of the function "SetCtrlVal" between constant and changing values so small ?

In my large application (1 MB exe-file) I am continuously updating a lot of numeric controls with new values. Most of them do not really change their value. Within my search of improving the performance of my application I noticed, that there is only a small difference of the execution speed between a call of "SetCtrlValue" with constant values and calls with changing values. It runs much faster (25 times on my PC), if I get the actual control value with "GetCtrlVal", compare it with my new value an do a call to "SetCtrlVal" only if the current value and the new value are different.
My questions to CVI-developers is:
Isn't it possib
le to do this compare within the function "SetCtrlVal"
My question to all CVI-users is:
Does anyone have similar tips to improve the performance of CVI applications ?
I developed a small test application for this problem, which I can mail to interested users.

What takes the extra time is the redraw of the control. When you call SetCtrlVal we ALWAYS redraw the control. We wouldn't want to build in functionality to check if the value was the same because that would add additional time to the SetCtrlVal in every case. If you want to do it outside of the loop you can as you have done above. You have a few options. First, keep a previous value variable for the controls that you can use to determine whether to set the control value. I.E.
int oldVal = 0;
int newVal = 0;
if(newVal!=oldVal) {
SetCtrlVal(..., newVal);
oldVal = newVal;
Also, if you set the value of a control through SetCtrlAttribute instead, there is no built in redraw of the control (which is what takes all the time). Using SetCtrlAttribute
to set the value is very fast, but remember there isn't a built in redraw on the screen to display the new number.

Reg Differrences between SynBo and Data Object

Hi,
I want to know the architectural diffrences between a SyncBo of MI 2.5 and Data Object of NWM 7.1. As it is given in help.sap.com documentation I think A data object support multiple levels of parent- child hirearchy where as a SyncBo is limited to one level of Header and Items.Similarly do any other differences exist?
2) In what way A data Object concept is better than that of a Synco.?
3) For manipulating the data of a data Object on Front end, Can we Use the existing SmartSync API of MI 2.5, or a seperate API for client side is going to be released?
Thanks in Advance,
Rajesh

Hello Rajesh,
1. The differences are small. You pretty much highlighted the biggest one (multi child node). Other differences exist in the fact that a SyncBO is linked to a backend BAPI as the DO is not (you would usually create the DO with the fields you need and then have backend adapters to fill it). Lifecycle of the DO is also different. Even release, non destructive change can happen and old application as well as new application will work at the same time. I can list a couple more, but I think you get that a SyncBO is different than a DO (even if in our development we still get mix both wording:))
2. Yes DO is a better concept than SyncBO.
3. There are 3 ways of accessing API on the client side. The first is the old SmartSync API which is only used in backward compatibility application (MAM for example). It should not be used for new development, but only to leverage existing one. After that you have two new frameworks for laptop and for PDA that you can find in NWDS 7.1. They reviewed the naming so I am not sure of the current ones, but I think it is something like Mobile Application for Handheld and Mobile Application for Laptop. Those two new framework uses WebDynPro flavored UI and provide access to the sync/data layer.
Thank you,
Julien.

What's the difference between "Normalization" and "Change Gain" ?

So I've got a bunch of tracks that I've mixed down and bounced to 24-bit stereo AIFF files. Next, I'll be mastering those bounced files with the Linear Phase EQ, followed by the Multipressor (if needed) and ending with the AdLimiter.
Needless to say, I'd like for all the tracks to have the same relative volume before starting the mastering process.
-3db is my desired level as it will give me a little room to play with during the mastering.
Anyway, I figured that I could simply normalize all the bounced files to -3db in the sample editor before mastering. But while looking into normalizing in the manual, I noticed the change gain function listed right below it.
However, unless I'm missing something, I don't see a real difference between the two.
Could any of you experts out there tell me if there is a real difference bewteen them? Are there clear advantages to using one over the other?
Thanks,
Ken

Logic Pro 7.2 User

Changing gain = changing gain. There's no functional difference, as I understand it, regardless of how the function is labeled. For example, if you have a waveform that peaks at -3 dB and you normalize it, the entire waveform's amplitude is recalculated so that now the -3 dB point is at a 0dB. This means that every other sample in the waveform had to also have its amplitude multiplied by some factor that results in an increase of 3 dB for every part of that waveform, proportionally. This means that your track will not sound more dynamic. It will have exactly the same dynamics as before, but the overall volume is greater. It's like turning up the volume control. Done.
If you used "change gain" instead of normalize and you changed the gain +3 dB, you'd be performing exactly the same function as described above, yes?
To take this one step further... if you didn't bother to analyze what level the waveform peaked at but used Change Gain to create an arbitrary +3 dB gain change, the waveform may clip if its peak amplitude was already pretty hot (Logic will warn you of this, but doesn't prevent you from creating a clipped waveform). On the other hand, the Normalize function performs an "auto peak search" before it sets out to increase the amplitude of the overall waveform so that the peak resides at 0 dB. Indeed, if you try to normalize an already normalized waveform, Logic will issue an alert message saying something like "already at maximum volume" or something like that, and no processing takes place.
So in a nutshell, Normalize will increase (and only increase) the gain of a waveform by first searching for the peak in that waveform and then increasing the overall gain of the entire waveform such that the peak resides at 0 dB. Change Gain allows you to increase or decrease the gain of a waveform (or a selected part of a waveform) by whatever amount YOU set it to be.
Kenmitch, I'm not convinced that your formulaic approch to mastering is going to give you the best sonic results. For one thing, pre-normalizing your tracks is apt to create headroom problems. I wouldn't do it.

How to transfer a module between systems and change the system name?

Hello,
I would like to transfer a module I've built from one server to another, my questions are:
1. What will be the best way to do it?
2. The 2nd Server contains a System with the same queries but the system has a different alias. Suppose I don't want to add to the system and the 2nd server the alias from the 1st system, is it possible to change the system in the module queries once it has been compiled and deployed?
Roy

Hi,
1) You can use the export/import features of VC to transfer models.
2) The requirement is not clear. I guess your alias name is different in the second system and you want the imported model to work fine with the current alias in second system.
To change the alias, goto Menu Tools ->Alias manager, select your system and replace it with the new alias. Then compile and deploy it.
Hope it helps
Regards,
Sooraj
