What exactly is Object Event Repository?

Hello,
I´ve just read a marketing article about the new SAP Object Event Repository. Precisely because it is a marking article the key-facts and functions are missing. It sounds like a reduced AII with extended database functions for Tag-tracking. Can somebody explain the benefit, technology and functions of the OER? What is the different between AII and OER?
Thank you, Bastian

Hi,
SAP OER serves as a system of record for uniquely identified objects (like EPCs). So you are right in saying it like an extended database functions for tag tracking.
But it will not reduce the AII functionalities. AII will still remain as the data capturing application (tag read) and the repository of these reads for the tags will be maintained in the OER. So these two are two different applications.
OER allows for tracking any id or document for which information has been sent from AII. OER will also have the capability of generating reports (business intelligence) for these data reads maintained in its repository.
SAP has recently unveiled is PTA (Product Tracking & Authentication) feature in OER. Read at http://www.sap.com/company/press/press.epx?PressID=7440
Since this product has not come in the market yet, we need to wait till the time of its release for documents on the product. Then we might know the exact benefits/technology on OER.
Thanks,
Ashish

What exactly are objects?

Hi, i am new to java and i do not exactly understand the concept of OBJECTS...they are somehow relates to methods and classes. Is there a place where is can know about objects in java? Maybe someone here can help me..

Think about it this way? What is an object? Is a man, woman, pen, employee, map, napkin? All of those are objects correct?
So in Object Oriented Programming, like Java, you can create something called a class that describes these.
An object or class(in most cases), is used to describe just that, an object.
For example, take a man, he is an object, so how would you descibe a man? Maybe, name, weight, height, hair color, or however much more detailed you want to get. So you create a class that contains all that information in a way that you can reuse it for any man object that you want to create later.
Does that make more sense?

Object event repository - events log?

Hi,
I'm doing AII - OER integration for PTA
when I an EPCIS event from AII to OER (for product tracking and tracing)
it gets posted in OER but there are no results - no objects get created
any tips on how to increase the logging level maybe?
thank you,

Hi,
I managed to check it inside the bapi call

Whats the business object attached to the transaction TBB1 ??

Whats the business object attached to the transaction TBB1 .
I am trying to post a loan contract fees and repayment from Treasury to GL.
Thanks ,
Naval Bhatt

Below is the exact requirement .... but there is no event generate right now ... I feel that there are some configurations need to be done ..for the event to be generated ...
It will be great if you have any idea about the configurations .. .
Objective:
When loan contract fees and repayment are posted from Treasury to GL, workflow should be activated to:
a. Insert a payment block 'Z' in the document (Will need to create a user-table to define the criteria where payment block is to be inserted), AND
b. Route the document for approval.
If amount < 10,000, only 1 level approval
If amount > 10,000, 2 levels approval required.

RE: Re[2]: Service Object events and LockMgr

I think there are a lot to implement a lock manager. If several objects
should be updated in one transaction, the lock manager should be able to
handle rollbacks. Other things like release lock when exception happens,
avoiding dead locks, etc. Most of the features are provided by DBMS, so
I think using a option 2 would be a better solution.

The second one - you just need some unique value that will identify
the object being locked. You should register with the Lock
Manager only
the objects that you want to lock.
For me, one of the goal of such pattern is to give you some freedom
from the specifics of the database lock mechanism.
Another benefit that I can see is that using such approach you can
always answer to the question: "Can I modify/delete this object?".

Re: Service Object events and LockMgr

On the option that you have considered, I have implemented the same model
in my previous project (using Java/RMI), but I felt that it is more than
what is normally needed for concurrency protection.
I can suggest another option that is worth considering which is in place in
our app for concurrency.
Almost every table in our db has created By, created On, modifed By,
modified On columns. The parent class of all business objects has
attributes that correspond to these four columns. In addition to these
four, there is a fifth attribute (introduced when concurrency was built)
called originalModifiedOn. Upon retrieval from the db, it is set to
modifiedOn value (from the db), during UPDATE, the value in this column is
added part of the WHERE clause. So when the second user tried to do save
the same object, the underlying db update will get a 'zero rows updated'
which is translated into an application error 'possible concurrency
error'. The user re-retreives the now 'stale' object before applying their
edits.
A lot of these things are and can be built into the framework imposing very
little work that each Object needs to do to have concurrency protection.
I am not sure if there is a mention in the Patterns paper of this model,
but it is very easy to implement and supports what is needed.

Hi folks,
We're currently looking at strategies for dealing with the simultaneous
updates to the database from multiple clients (concurrency
management). That is when two (or more) clients load the same object to
edit it, then make different changes and save them to the database.
We have a copy of a Forté document (from the "Patterns" course, I
think) which describes three methods of dealing with this:
1) Lock the database table row as soon as a client select it for editing
and hold the lock until it is saved.
2) Immediately before 'saving' check that the database hasn't changed
(either by reading what's there before updating, or by using a huge
'where' clause that contains all unchanged fields)
3) The Forté "LockMgr" pattern, which uses a service object with notifier
proxies to allow locking and updating notification between the clients.
Option 3 is obviously the most robust method, but it requires a fair
amount of coding and could also be a bottleneck for database reads and
writes.
But I have another option for which I was looking for opinions. What if
we had a "Change Event manager" which broadcast an event every time
a change is made to the database. Each business class would have its
own event. If the event had the object's primary key as a parameter, then
clients editing that particular object type could check to see if the object
currently on screen is the one that changed. That way you could disable
the 'save' until they had refreshed their on-screen data.
It's not particularily elegant, but it's reasonably simple to implement. It
also deals with changes sent across our WAN from other database
servers.
But this option is only worthwhile if you can replicate the "Change Event
manager" SO and still register for an event on the client. Can clients
register for SO events and receive an event generated by any of the SO's
replicates? Or when you register for an SO's event do you register for
only one instance of the SO?
Thanks in advance for any answers.

What is a Business Process Repository and where do we get it in SAP?

Hi,
What is a Business Process Repository and where do we get it in SAP?

Hi,
Here is an another way to look at the BPR-Business Process Repository delivered by SAP.
1. Add the Web Dynpro application Business Process Repository (BPR) to your Favorites:
2. Choose Favorites Add Other Objects Web Dynpro Application in the SAP initial screen.
3. Enter SM_BPR_OVERVIEW in the field Web Dynpro Application.
4. Enter a description like ex. SAP BPR
5. Save your changes.
6. Now Call the saved - Web Dynpro application SM_BPR_OVERVIEW
7. You can see the BPR in a new browser window.
This info is available in SAP Help on Solution Manager.
Hope this helps.

What exactly is InheritableThreadLocal Storage, and how exactly do I use it

What exactly is InheritableThreadLocal Storage, and how exactly do I use it?

What exactly is InheritableThreadLocal Storage, andI have only seen one previous use of ThreadLocal objects and it was somewhere on http://www.javaworld.com on a solution to the Java double-checked locking problem.
Roughly speaking, previously to Java1.2 you had two variable-type choices in Java. The first is a static variable that is the same across ALL instances of a class. The second was an instance variable, that is can be different in EVERY instance of a class. Java 1.2 introduced the ThreadLocal variable-type. If a variable type is ThreadLocal, then every running Thread may see a different value for the variable - essentially it is a Map of Threads to values.
InheritableThreadLocal is finely different from ThreadLocal. They are almost identical excepting that if one Thread is spawned from another (ie. it is a "child" thread) then the value of the InheritableThreadLocal variable will be the same in the child Thread as the parent Thread.
As to when it could be used, I'm not so sure (other than the no-brainer "when you want a variable to have different values in different Threads"). I'd be interested to hear about any instances where someone has used a variable such as this.
how exactly do I use it?Carefully

What are administered objects

Examples of administered objects are apparently JMS destinations and connection factories, but what exactly are they?
Can anything "managed" by the container be called an administered object (e.g. EJBs, DataSources, etc)?
resource-ref is used to indicate "resource manager connection factory" objects, while resource-env-ref is used to indicate "admistered objects associated with resources", though that doesn't clear up much...
Could anybody please clarify?
Thanks.

Administered object is a term used by the connector specification to describe global resources exposed by resource adapters and other backend systems. JMS destinations and connection factories are two good examples.
Regarding the Java EE private component environment (java:comp/env),
the original intent was that resource-refs be used to refer to
factory objects such as JMS Connection Factories and Datasources, whereas resource-env-refs
refer to opaque resources such as JMS Destinations. In retrospect it
didn't help that much to make that distinction and it has caused a lot of confusion.
The annotations in Java EE 5 help abstract a lot of this by allowing @Resource
to be used for anything that would map to either a resource-ref or resource-env-ref.
Things like ejb references, web service references, and persistence unit/context references
each have special enough behavior that they are assigned their own unique environment
types, so those would not be refered to as administered objects.

Sync - merge - what EXACTLY do these terms mean?

Howdy. I recently plunged into the iPhone world & I'm LOVING IT!!!!!!
So, what exactly does SYNC & MERGE mean? what will be the final results?
with my iPod shuffle, I'm able to "auto fill" from a folder of pre-selected podcasts in iTunes. After listening to the iPod for awhile, I reconnect the iPod to iTunes (on the computer) & the podcasts in iTunes are updated as with actions taken on the iPod. for example, iTunes on the computer will indicate wether or not I listened to these particular podcasts on the iPod or not, & will also remember where I left off. So it seems that the iPod updates iTunes on the computer.
But, ... this does NOT seem to be the same with the iPhone. It seems like when I plug in my iPhone to the computer & "sync", iTunes isn't updated as to what I already watched on the iPhone, like the iPod did. In order to update iTunes with what i already watched on the iPhone, I need to manually delete the vidcasts from the iTunes on the computer, which seems like a step back from my little iPod shuffle.
ALSO: if I change contact information on my iPhone, will this updated info be lost when I connect the iPhone to the Computer?
So what exactly does SYNC & MERG mean?
It seems that the iPhone reacts differently for different media. I'm very confused & I wish there was a place to understand all this without the generic "sync" word being used without explanation. does sync mean replace, update, ... ????
I've been searching around the net for this info for awhile, but all I find is these terms, without sufficient information as to what exactly MERGE & SYNC actually do.
Can someone suggest some place that explains this in the detail I'm looking for?
Thanks so much.
Jesse Luke

Under the Podcasts tab for your iPhone sync preferences, there are various options. I have sync all unplayed episodes of selected podcasts to be transferred to my iPhone. If I listen to an podcast on my iPhone in it's entirety, the podcast will be removed from my iPhone when syncing with iTunes.
The iPhone includes a sync process - some of the data included with the sync process is a one way transfer process only from your computer to your iPhone such as iTunes music, and the same for selected photos to be transferred from your computer to your iPhone.
The sync process for contact info, calendar events, and Safari bookmarks with the supported applications on your computer is a bidirectional or true sync process. When syncing an iPhone for contact info the first time with a supported application on your computer that includes contact info, you will be provided a merge prompt if your iPhone includes any contact info that was manually entered in your iPhone's address book. This will merge the contact info between the two. After the first sync or merge for this data, it will be a bidirectional or true sync process. Change info for a contact on your iPhone, and the info will be changed for the contact info with the supported address book on your computer when followed by a sync, and vice-versa. Add a new contact with the supported address book on your computer, and the new contact will be transferred to your iPhone's address book during the next sync, and vice versa. The same applies to calendar events when syncing with a supported calendar app on your computer.

What exactly are Field symbols?

Hi SDN,
What exactly are Field symbols?
I have read they are not pointers then what are they?
Regards,
Rahul

Hi
see this
Field Symbols
Field symbols are placeholders or symbolic names for other fields. They do not physically reserve space for a field, but point to its contents. A field symbol cam point to any data object. The data object to which a field symbol points is assigned to it after it has been declared in the program.
Whenever you address a field symbol in a program, you are addressing the field that is assigned to the field symbol. After successful assignment, there is no difference in ABAP whether you reference the field symbol or the field itself. You must assign a field to each field symbol before you can address the latter in programs.
Field symbols are similar to dereferenced pointers in C (that is, pointers to which the content operator * is applied). However, the only real equivalent of pointers in ABAP, that is, variables that contain a memory address (reference) and that can be used without the contents operator, are reference variables in ABAP Objects.
All operations programmed with field symbols are applied to the field assigned to it. For example, a MOVE statement between two field symbols moves the contents of the field assigned to the first field symbol to the field assigned to the second field symbol. The field symbols themselves point to the same fields after the MOVE statement as they did before.
You can create field symbols either without or with type specifications. If you do not specify a type, the field symbol inherits all of the technical attributes of the field assigned to it. If you do specify a type, the system checks the compatibility of the field symbol and the field you are assigning to it during the ASSIGN statement.
Field symbols provide greater flexibility when you address data objects:
If you want to process sections of fields, you can specify the offset and length of the field dynamically.
You can assign one field symbol to another, which allows you to address parts of fields.
Assignments to field symbols may extend beyond field boundaries. This allows you to address regular sequences of fields in memory efficiently.
You can also force a field symbol to take different technical attributes from those of the field assigned to it.
The flexibility of field symbols provides elegant solutions to certain problems. On the other hand, it does mean that errors can easily occur. Since fields are not assigned to field symbols until runtime, the effectiveness of syntax and security checks is very limited for operations involving field symbols. This can lead to runtime errors or incorrect data assignments.
While runtime errors indicate an obvious problem, incorrect data assignments are dangerous because they can be very difficult to detect. For this reason, you should only use field symbols if you cannot achieve the same result using other ABAP statements.
For example, you may want to process part of a string where the offset and length depend on the contents of the field. You could use field symbols in this case. However, since the MOVE statement also supports variable offset and length specifications, you should use it instead. The MOVE statement (with your own auxiliary variables if required) is much safer than using field symbols, since it cannot address memory beyond the boundary of a field. However, field symbols may improve performance in some cases.

Syntax Diagram
FIELD-SYMBOLS
Basic form
FIELD-SYMBOLS <fs>.
Extras:
1. ... TYPE type
2. ... TYPE REF TO cif
3. ... TYPE REF TO DATA
4. ... TYPE LINE OF type
5. ... LIKE s
6. ... LIKE LINE OF s
7. ... TYPE tabkind
8. ... STRUCTURE s DEFAULT wa
The syntax check performed in an ABAP Objects context is stricter than in other ABAP areas. See Cannot Use Untyped Field Symbols ad Cannot Use Field Symbols as Components of Classes.
Effect
This statement declares a symbolic field called <fs>. At runtime, you can assign a concrete field to the field symbol using ASSIGN. All operations performed with the field symbol then directly affect the field assigned to it.
You can only use one of the additions.
Example
Output aircraft type from the table SFLIGHT using a field symbol:
FIELD-SYMBOLS <PT> TYPE ANY.
DATA SFLIGHT_WA TYPE SFLIGHT.
ASSIGN SFLIGHT_WA-PLANETYPE TO <PT>.
WRITE <PT>.

Addition 2
... TYPE REF TO cif
Addition 3
... TYPE REF TO DATA
Addition 4
... TYPE LINE OF type
Addition 5
... LIKE s
Addition 6
... LIKE LINE OF s
Addition 7
... TYPE tabkind
Effect
You can define the type of the field symbol using additions 2 to 7 (just as you can for FORM parameters (compare Defining the Type of Subroutine Parameters). When you use the ASSIGN statement, the system carries out the same type checks as for USING parameters of FORMs.
This addition is not allowed in an ABAP Objects context. See Cannot Use Obsolete Casting for FIELD SYMBOLS.
In some cases, the syntax rules that apply to Unicode programs are different than those for non-Unicode programs. See Defining Types Using STRUCTURE.
Effect
Assigns any (internal) field string or structure to the field symbol from the ABAP Dictionary (s). All fields of the structure can be addressed by name: <fs>-fieldname. The structured field symbol points initially to the work area wa specified after DEFAULT.
The work area wa must be at least as long as the structure s. If s contains fields of the type I or F, wa should have the structure s or at least begin in that way, since otherwise alignment problems may occur.
Example
Address components of the flight bookings table SBOOK using a field symbol:
DATA SBOOK_WA LIKE SBOOK.
FIELD-SYMBOLS <SB> STRUCTURE SBOOK
DEFAULT SBOOK_WA.
WRITE: <SB>-BOOKID, <SB>-FLDATE.

What exactly is the difference between enqueue,latch & lock

Can someone explain in simple words (with example if possible) what exactly is the difference between enqueue,latch & lock?
I have gone through documentation & other links,but just not able to figure out the exact & clear difference between these three..
Cheers,
Kunwar

In addition to links provided by Sb and nice explanations by Aman, i would like to add below :
1.Latches and enqueues are lightweight serialization devices used to coordinate multi-user access to
shared data structures, objects and files.
Latches are locks that are held for extremely short periods of time, for example the time it takes to modify
an in-memory data structure. They are used to protect certain memory structures, such as the database
block buffer cache or the library cache in the shared pool (as described in Chapter 2, Architecture). Latches
are typically requested internally in a ‘willing to wait’ mode. This means that if the latch is not available,
the requesting session will sleep for a short period of time and retry the operation later. Other latches may
be requested in an ‘immediate’ mode, meaning that the process will go do something else rather than sit
and wait for the latch to become available. Since many requestors may be waiting for a latch at the same
time, you may see some processes waiting longer than others. Latches are assigned rather randomly, based
on the ‘luck of the draw’, if you will. Whichever session asks for a latch right after it was released will get it.
There is no line of latch waiters, just a ‘mob’ of waiters constantly retrying.
Oracle uses atomic instructions like ‘test and set’ for operating on latches. Since the instructions to set
and free latches are atomic, the operating system itself guarantees that only one process gets it. Since it
is only one instruction, it can be quite fast. Latches are held for short periods of time and provide a
mechanism for clean-up in case a latch holder ‘dies’ abnormally while holding it. This cleaning up
process would be performed by PMON.
Enqueues are another, more sophisticated, serialization device, used when updating rows in a database
table, fro example. They differ from latches in that they allow the requestor to ‘queue up’ and wait for
the resource. With a latch request, the requestor is told right away whether they got the latch or not.
With an enqueue, the requestor will be blocked until they actually attain it. As such, they are not as fast
as a latch can be, but they do provided functionality over and above that which a latch can offer.
Enqueues may be obtained at various levels, so you can have many ‘share’ locks and locks with various
degrees of ‘shareability’.

Hi
In which version of SAP are you working?
Matchcodes are replaced by SEARCH HELPs in latest versions
see the doc
1) Elementary search helps describe a search path. The elementary search help must define where the data of the hit list should be read from (selection method), how the exchange of values between the screen template and selection method is implemented (interface of the search help) and how the online input help should be defined (online behavior of the search help).
2) Collective search helps combine several elementary search helps. A collective search help thus can offer several alternative search paths.
3)An elementary search help defines the standard flow of an input help.
4) A collective search help combines several elementary search helps. The user can thus choose one of several alternative search paths with a collective search help.
5)A collective search help comprises several elementary search helps. It combines all the search paths that are meaningful for a field.
6)Both elementary search helps and other search helps can be included in a collective search help. If other collective search helps are contained in a collective search help, they are expanded to the level of the elementary search helps when the input help is called.

Collective search help Combine several elementary search helps. A collective search help thus can offer several alternative search paths.
A Collective search help provides alternative search
Paths by combining elementary search helps.
Only one search help can be attached to a field, table or data element. Several search paths are therefore attached with a collective search help.
A collective search help also has interface parameters like
an elementary search help.
Like an elementary search help, a collective search help has an interface of IMPORT and EXPORT parameters with which the search help exchanges data. Using this interface, the collective search help can be attached to fields, tables and data elements exactly like an elementary search help.
Parameter assignment needs to be done for each of the
Included search helps.
When you define a collective search help, there are no components for describing the dialog behavior and data selection; instead the included search helps are listed here. You must assign the parameters of the collective search help to the interface parameters of the included search help for each inclusion.
User may choose the tab and thus the elementary
search maethod.
When we execute the search help SCUSTOM, we are confronted with a dialog which gives us an option of either restricting
By 1)Search for customer according to booking
2)Search for customer according to name.
These are effectively the elementary search helps (SCUSTOM_BOOK and SCUSTOM_NAME) which have been included in the collective search help SCUSTOM.
HOT KEY
The hot key is used to select the elementary search help from the collective search help and to enter the restrictions in the dialog box for restricting values directly from the entry field. If the user often searches for values using the same search help, this procedure can save time.
Steps to create a Collective Search Help
1)Enter the search help name and click on create.
2)Choose Collective search help radio button option as the search help type.
3)Enter the search help parameters.
4)Instead of the selection method, we enter the included
search helps for the collective search help.
5)We need to assign parameters for each of the included
search helps.
6)Complete the parameter assignment by clicking on the push button
7)Collective search help offers the user to obtain F4 help
using any of the included search helps.

What are saved objects in HFM

Hi Experts
What are saved objects in HFM? Plz give me an example?

Hi Smilee
Saved objects are related to Financial Reporting.
Saved objects option is used to avoid the recreation of code, thus I find it valuable to turn all report header and footer information into saved objects. Items such as company logo’s, report title/sub-tile information, dimensional point-of-view selections, date & time stamps, page numbers and data source information make for great saved objects as they typically reside on all financial or management reports.
The usefulness of report objects may seem less important during the early stages of development, but as your reporting repository grows, their impact becomes increasingly important. For example, changing a company logo on a few reports is a minor incontinence, but making that same change to 50 reports could take hours to complete, resulting in the inefficient use of development/ maintenance time.
For more information please go through the below link.
