Difference between Function and Automated Activity

Hi All,
After struggling with a few BPA Suite/JDev compatibility issues over the past few days, we've finally got a basic setup up and running (JDev 11.1.1.1 worked - 11.1.1.2 did not).
I'm new to BPA and have 2 fairly basic questions - haven't found conclusive answers to these and hence, raising it on this forum...
1. What is the difference between a "Function" and an "Automated activity" in the BPA Suite? I had expected the latter to translate to a BPEL invoke but what appears to happen is:
- "Function" tranlsates to a BPEL Scope + Invoke.
- "Automated activity" translates to a BPEL Scope + Empty Task.
Based on this, I would not plan to use a "Function" for web service invocations but not sure where I would use the automated activities.
2. Is there a BPMN construct that would translate to a BPEL "Assign"? I understand that an Assign is fairly low-level and would normally be expected to be filled in by the BPEL developer (and not by the Business Analyst specifying the BPMN model) but it would be quite handy to be able to specify this in BPMN in some cases..
Thanks..

That's because the data is passed back through a special "pipeline", and you can write code to show that the data is available to a query as soon as it's piped, and before the function has completed (reached the return statement) if you like.
A procedure does not return a value (And no an OUT parameter is not a "returned" value, it's a writeable parameter, there's a difference)
2. There are some limitations in functions which is possbl through procedures.
Like - Oracle doesn't support DML in functions called in Select queries (using PRAGMA AUTONOMOUS_TRANSACTION will help).Not strictly true. and SQL query is considered to be DML, so a function could perform a query and then be used inside another query...

Difference between standard and actual activity rates

Dear All,
My client is having a process in which while downloading KOB1 the system is giving report of all the process orders wise activities confirmed in that month against some cost center.
Now when i am going into line item it takes me to process order confirmation display where activiies to be confirmed and activities yet to be confirmed are displayed.
After that cost center report S_alr_87013611 is displayed wherein actual rates(quantity ) is displayed for that activities.
Now the system shows difference between actual and standard activities.
The difference is the calculated in excel on the basis of KOB1 report and difference is loaded process order wise on calculation done in excel through LSMW (for transaction KB21n) wherein difference quantity is posted from cost center to process order.
Now client needs automation in the sense that no excel calculation should be done and difference should be posted for that month for each process order in the ratio calculated in excel.
Kindly provide any solutions if any, avaliable in standard or Z development has to be done.
Thanks and Regards,
VLM

Dear AP,
Have you any idea about how in above case Z development is to be done?

VLM

Difference between Function and Stored Procedure

Hi guys, i don't understand the exact difference between a function and a stored procedure. I did lot of google but still. Can somebody explain in simple words. Thanks.

Hi,
Here's an example of a user-defined function:

(      in_num       IN     PLS_INTEGER
RETURN     PLS_INTEGER
DETERMINISTIC
IS
BEGIN
     IF in_num IS NULL
     THEN
          RETURN     NULL;
     ELSIF in_num <= 1
     THEN
          RETURN 1;
     ELSE
          RETURN in_num * factorial (in_num - 1);
     END IF;
END     factorial;
SHOW ERRORSThis function retruns an integer. You can use the function (or, more properly, the integer that it returns) anywhere an integer expression is allowed.

Difference between function and procedure

Hi all,
Please send me the difference b/w functions and procedures.
Regards
dskumar

A procedure may(1 or many) or may not return a
value,I have yet to see a procedure returning a value. Whilst it can pass out values using OUT and IN OUT parameters, it doesn't RETURN values.
A function always returns one value.A function may also include OUT and IN OUT parameters to pass back values but it's not recommended.

Re: Difference between function and procedure

Hello Oracles Guru’s,
I am learning Oracle and I am beginner. My question may be simple and not worth to ask but I am sorry
Why we call Procedures as Stored Procedure but we call functions only functions.
As per my understanding I think but the objects are stored as objects in the database.
Please clarify.

Difference between Macros and subroutine

Hi all,
What is the difference between the macros subroutine and function module functinalitywise.;

Hi,
Macros can only be used in the program the are defined in and only after the definition.
Macros can take max 9 parameters.
Macros are expanded at compilation / generation.
Subroutines (FORM) can be called from both the program the are defined in and other programs ('perform
' of 'perform in program ').
Subroutines can take any amount of parameters.
Subroutines are 'expanded' at runtime.
Functions are just like FORMs, but are intended to be called external.
Some differences between FUNCTIONs and FORMs:
The name of a FORM must be unique within the program (two programs can have different FORMs with the same name). A FORM is intended to be called internal (from within the program, however by a 'trick' you can call them external).
The name of a FUNCTION has to be unique throughout the system. A FUNCTION is intended to be called external (and is thus shared by 'many' programs).
The latter is more important for programmers and maintenance. Since a FUNCTION is called external, it is important to keep the interface (parameters) the same. The interface of a FORM (which is intended to be called internal) is check when debugging a program (but it is only checked within the program that is debugged). So if the interface of a FORM is changed, but the call to the FORM (perform ) is not, the debugger will notice this and issue an error message.
In general:
A MACRO is more or less an abbreviation for some lines of code that are used more than once or twice.
A FORM is a local subroutine (which can be called external).
A FUNCTION is (more or less) a subroutine that is called external.
Since debugging a MACRO is not really possible, prevent the use of them (I've never used them, but seen them in action). If the subroutine is used only local (called internal) use a FORM. If the subroutine is called external (used by more than one program) use a FUNCTION.

Activity System status: differences between u0093Openu0094 and u0093In processu0094 status

Dear Experts,
Whats the difference between Open and In process system status? In help.sap.com it: There are four system statuses that represent the life cycle of the business transaction:
Open: has been recently created and not yet processed (for example, contract from the Internet)
In process: administrator is clearing up questions
But, how does the system assumes the In Process status ?? Ive tested business activities creation with different employees assigned and, when editing and saving the business activities with these BPs the system status does not change.
However, in other unknown situations the status system is changed to in Process.
Any ideas about the meaning of the In Process status? And when the business activity switches to that?
Thanks in advance,
Joao

Hi,
These four system statuses that represent the life cycle of the business transaction:
·        Open: has been recently created and not yet processed (for example, contract from the Internet)
·        In process: administrator is clearing up questions
·        Released: contract is complete and legal. Follow-up processes can be started (printing, billing, distribution, releases and so on)
·        Completed: All actions directly linked to contract are completed
·        Closed: all actions indirectly linked to the contract are closed (for example, from R/3: batch run to actual costs)
Each status having its own control at the configuration level. If you observe the following process you may understand the importance of various statuses.
For example in any transaction by default status would be Open. Once the transaction opened by the respective responsible person he will change the status as In Process, Once the assigned task is completed he will change the status as Completed.
Please notice the configuration settings in the following navigation path:
SPRO->IMG->CRM->Transactions->Basic Functions->Status Management-> Change Status Profile for User Status->Select Quotation->Double click on the different status. You can observe the difference.
Hope I convinced.
Best Regards,
Johnny.

Differences between procedures and functions.

a little confusing ..in differences between procedures and functions..
1. Can a function return only single value?? cant we return multiple values?
2. Can we use 'out' parameter and 'return' clause at a time in the same function
thank you

Hi,
newbie wrote:

1. Can a function return only single value?? cant we return multiple values?Yes, a function can only return a single value.
If the return type is some kind of collection or data structure, then that 1 collection or data structure can, of course, actually contain many sep[arate values.
If you want to return multiple values, use a PROCEDURE with multiple OUT arguments. (Functions can have OUT arguments, too, but avoid defining functions with OUT arguments. It can cause a lot of confusion.)
2. Can we use 'out' parameter and 'return' clause at a time in the same functionSure, but don't take my word for it. Try it and see.

What is the difference between subroutine and function module?

What is the difference between subroutine and function module?

Hi,
they can both return values.
FMs are mainly used when a routine is to be performed by many programs.
Subroutines (forms) are generally only executed within one program.
You can perform routines from other programs, but it's not often done.
both forms and FMs are reusable modularization units.
To distinguish we generally say that forms are used for internal modularization and
FMs are used for external modularization.
To decide on which to implement, consider whether you need the content to be used just for a limited program
or wheteher it can be called from many independent programs.
For the first purpose it is better to implement a form whereas for the second we implement an FM.
However, ABAP does not isolate the usage context.
That is; you can call a form from another program within whose code the form is not actually implemented.
However, this requires attention since the form may utilize global variables.
The same issue holds for FMs.
FMs are encapsulated in function groups and function groups may have global variables that can be globally
used by all FMs inside it.
Thanks,
Reward If Helpful.

What are the differences between inactive and active ABAP objects?

Can anybody tell me what are the differences between inactive and active ABAP objects?
In my opinion, an active object is compiled and system wide available, that means the system do not have to compile the program again before run or use the object. While An inactive object is not system wide available and every time you run an inactive object, firstly the abap runtime will have to generate a tempory runtime object and this inactive object can not seen by others.
Am I right? Can anybody kindly tell me other differences?

Hi,
"When it is inactive, it is like it would not exist at all:" no - it's like it only exists to you
"If we just saved that one means it is stored in application server not in database": no - the inactive version is also stored in the database. You can log off and log on and it will still be there, in its inactive status.
"Only active objects can be executed.": no - inactive objects can be executed by you
When you create or modify a program, it is inactive until you activate it.
With a change, there are two versions of the program stored in the database - the active version (as it was before you made your change), and the inactive version. If you attempt to run the program, you'll run the inactive version - the one with your changes. Everyone else on the system will run the active version.
In this way, you can make changes without affecting anyone else.
Once you activate your program, then the inactive version becomes the active version.
With a create, there is no active version, until you hit the activate button. This means ONLY you can run the program.
An additional benefit of this model, is that if you make a change, save it, and then change your mind without activating, you can recover the active version into the editor, using version management.
A downside is that sometimes you have to activate your change before you can test it, if it interacts with other, active, programs.

Kumar

Functional differences between OBISE1 and OBIEE

Hello,
beside the licensing restrictions, there are some funtional differences between OBISE1 and OBIEE. I have seen some very neat features in OBIEE which are not implemented in OBISE1, e. g. generating powerpoint or the assistants for bi publisher in word. The actual release of EE is 10.1.3.4.0 and it is 10.1.3.2.1 for SE1. Does anyone know, if SE1 will be upgraded to 10.1.3.4.0? And if yes, will Interactive Dashboards, Answers and BI Publisher in this relaese have the functional range of EE?
Thanks in advance for your answers.
Thomas

Balaa,
This question has been posted a number of times. Yes, Server, Answers, Dashboards and Publisher are functionally identical in BISE1 and BIEE. You can use BIEE 10.1.3.4.1 to upgrade your BISE1 10.1.3.2.1 (Oracle trust you not to use the stuff you are not licensed to use such as Delivers).
See my oracle support note document id 743916.1 on metalink3 ...
Oracle BI SE1: Patch to 10.1.3.4
Upgrading Oracle Business Intelligence Standard Edition One to higher versions of the underlying components
"Customers may upgrade to the latest 10.1.3.x versions of the BI components by running the BI Enterprise Edition 10.1.3.x Installer. They will be alerted that there is an installation already present and prompted to preserve the existing configuration. They should choose that option and the installer will leave the existing configuration (to include Repository, Web Catalog, etc) in tact and install the newer versions of the components. Note that when upgrading, all BI components must be upgraded to the same version. Customers may upgrade to the latest versions of Oracle Database 10g or Oracle Warehouse Builder 10g by applying the supported appropriate patches as needed. A note on platform support -- Oracle BI SE One is available for Windows platforms only. Oracle does not support Oracle BI SE One on other platforms. A note on licensing -- By license, customers are restricted to using BI Server, BI Answers, BI Dashboards, BI Publisher, BI Administration Tool, Oracle RDBMS, Oracle Warehouse Builder Core ETL functionality. Note that the BI SE One installation installs all of the BI components -- those listed above as well as Delivers, Office Plug-in, etc. If customers wish to use those additional components they are required to upgrade to a BI Enterprise Edition license."
