Implicit and Explicit Enhancement

Hi Gurus ,
Can anyone please let me know about what is implicit enhancement and explicit enhancement.Steps involved in the same .
Thanks ...

Hi
Implicit enhancement points are basically points within ABAP code where an enhancement point is implied, and in which case can be created. Examples of implicit enhancement points are at the beginning and end of FORMs, at the end of a program, include or function module etc. Below is a step by step demonstration of how to create and implicit enhancement point.
Explicit enhancement points are basically hooks already coded into the program by SAP at various points of the code. See program RIAUFMVK for examples of these! These are very easy to implement simply go into enhancement mode of SE80 and right click on the enhancement point where you want to add your code and choose Enhancement Implementation->Create Give it a name, description and assign it to a change request (should not be a Z package) and then simply add the code as normal

Difference between implicit and explicit enhancement points

Hi Folks,
I had learned many documents to findout the difference between explicit and implicit enhancement point.I got the theoritical knowledge on that but losing on the practical side..
Can anybody help me out with one real time scenario where the explicit enhancement points have been implemented and the step by step procedure to implement it..
Hoping for the positive response from you..
Regards,
Rohan.

Hi Rohan,
In implicit they are available at the beginning of subroutines defined in the standard reports.
Edit-> Enhancement operations->show implicit enhancement options.
This will highlight all the implicit enhancements in the report.
In Explicit enhancement we have two different types of enhancements -
Enhancement point and Enhancement section.
Enhancement point - SAP has some standard functionality defined for a report , but it may be required that you'll need to add your own code. In this case the code that you'll add will be executed along with the standard code.
Enhancement section - SAP has its standard functionality defines but it may not suit your requirement, in that case you may need to add your code and you'll need that code to be executed only. By this method the existing code is automatically commented and a copy of the same code is available to edit.
After executing the report only your code will be executed and the standard code will be bypassed.
For Practicle implementation, follow this link.

How to implement implicit and explicit enhancement points

Hi,
Can anybody please provide some technical aspects of enhancement spots. I have gone through several sap sites and help poratl but have not get much technical things (how to implement or related t codes). please do not provide link to read theories.

Difference between implicit enhancement and explicit enhancement

What is the difference between implicit enhancement and explicit enhancement .

Hi Peters,
Implicit enhancement option
Throughout the ABAP system, enhancement options are automatically available at certain pre-defined places. Some of the implicit options are:
u2022 At the end of all the programs (Includes, Reports, Function pool, Module pool, etc.), after the last statement
u2022 At the beginning and end of all FORM subroutines
u2022 At the end of all Function Modules
u2022 At the end of all visibility areas (public, protected and private) of local class
To view all the implicit options available in a source code, choose u2018Edit -> Enhancement Operations -> Show Implicit Enhancement Optionsu2019 from the editor.
Befor that you click on the spiral icon button in the application toolbar
Explicit enhancement option
The Implicit enhancement options are provided at specific source code places explicitly by SAP (Note that these enhancement definitions can also be created by partners and customers in their code).
There are two types of Explicit Enhancement options available. One which can be provided at a specific place - called Enhancement Point, and another which can be used to replace a set of statements u2013 called Enhancement Section. For this, we now have two new ABAP statements, viz.
u2022 ENHANCEMENT-POINT
u2022 ENHANCEMENT-SECTION
When the Enhancement-Section is implemented, only the implementation gets executed and the original code doesnu2019t get executed. This is a new technique, which didnu2019t exist previously in any of the old ways of enhancing, to exclude any standard SAP code from execution. Because of this, there can be only one active implementation of an Enhancement-Section. On the other hand, there can be multiple active implementations of an Enhancement-Point, in which case all the implementations will be executed with no guarantee in the order of execution.

What does "Implicit" and "Explicit" means????

-- after reading various Java books, articles, magazines, forums .... etc...
These two words: "Implicit" and "explicit" always appear on every text ...
-- Does implicit means "directly" and explicit means "indirectly"?
thanks

ways appear on every text ...
-- Does implicit means "directly" and explicit
licit means "indirectly"?
thanks"implicit" means that something is executed that is not written in your code
"explicit" means that whatever is executed specifically exists in the code.
For instance: "a base class constructor implicitly calls super() if you don't explicitly call super yourself."
That means even though it is not written in the code, the line:
super();
will be executed unless you explictily include a call to super() yourself, such as:
super(10, 14.6, "some text");

Difference between Implicit and Explicit Cursors

Hi All,
Can you just tell me what is the difference between implicit and explicit cursor?
Thanks,
Padma

Hi ,
Implicit Cursor means ,the cursors which are defined impplicitly.Here we use curosr variables as "SQL%found,sql%not found,sql%is open.."
but explicit cursors defined by us like if u create a cursor C1 then
c1%found,c1% not found ,c1%open
Thank you.

Implicit and explicit Type conversion using Type object in heap

Hi,
I am surprised how Implicit and explicit Type conversion works using Type object in heap. for example when implicit type conversion occur what pointer it returns to object and similarly with explicit type conversion.

Hello,
>> I am surprised how Implicit and explicit Type conversion works using Type object in heap.
For Implicit conversions: Typical examples are conversions from smaller to larger integral types, and conversions from derived classes to base classes. For the first one, the reference would be different which means it would return a different pointer to
a new object. For the reference type, it actually points to the same memory location, you could use the object.ReferenceEquals() to check it.
For Explicit conversions (casts):Typical examples include numeric conversion to a type that has less precision or a smaller range, and conversion of a base-class instance to a derived class. For first one, it would perform the same with implicit conversions.
While for the conversion of conversion of a base-class instance to a derived class, actually, there's no built-in way to do this conversion.

Implicit enhancement and explicit enhancement

Hi Experts,
I have implemented one requirement using implicit enhancement but i want to check whethere there is any explicit nhancement or not. Please let me know if any one of you have idea on that in VF02 transaction to do changes in pricing details.
Regards,
Dileep.

Hi,
For VF02 Programe Name SAPMV60A goto this programe in this we have somany explisit Enhanacement spots, just click Binacular Icon(Find button) and paste Enhancement Spot it will disply list of explisit enhancement spots, select your spot and just right click and create spot and do changes according to your requirement.

H2 devide implicit and explicit created indexes by dictionary views?

For migrating amounts of data it is useful to drop and recreate indexes and referencing constaints. A implicit created index by defining a primary/unique key constraint will be dropped implicitly by dropping the before mentioned constraint. Creating such a constraint after creating an equivalent index with the constraint name will result in an other behaviour. The explicit created index will not be dropped by dropping the referencing primary/unique key constraint.
So far so good and well known. The question is: Which dictionary view columns will show me the difference between implicit and explict created indexes if I try to dynamically drop and recreate indexes and unique / primary key constraints?

Oracle Version is always helpful in answering questions, but for 9i you can find the system generated by:
dba_indexes.generated = 'Y'
or
'SYS_' naming convention for system generated indexes
or
dba_constraints.constraint_name = dba_constraints.index_name
Hope this helps - JTommaney

Cat2 badis and implicit and explicit "Z " enhancement

Implicit and explicit?

Hi:
What is meant when a parameter or a cast etc. is referred as implicit?
What is meant when a parameter or a cast etc. is referred as explicit?
Thanks.

implicit: Implied or understood though not directly expressed.
For instance:
Integer i = new Integer(42);
Object obj = i; // Implicit cast from Integer to Object
explicit: Fully and clearly expressed; leaving nothing implied.
For instance:
Object obj = new Integer(42);
Integer i = (Integer)obj; // Explicit cast from Object to Integer

Implicit and explicit cursors

i want to know when to it is recommended to use the implicit cursors (for rec in.) and when it is recommended to use explicit cursors(open cursors.)

As Brett said, both methods require an explicit cursor definition. What is implicit in the FOR cursor loop is the opening and closing of the cursor. If you use a cursor FETCH loop, you need to code that explicitly yourself.
My recommendation is to use the cursor FETCH loop and code those two additional OPEN CURSOR and CLOSE CURSOR statements. Reason: a cursor fetch loop allows for proper bulk processing code to be used. It does not rely on the implicit bulk fetching (of 10 rows per time) of a FOR cursor loop - which btw is only available in 10G.
A FOR cursor loop does not scale. You cannot make the bulk fetching larger. Or smaller. You cannot do bulk updates or inserts in the loop.
So I do not care what the experts think and say, for me the answer is clear cut. You want to write scalable and performant code? You will use a cursor fetch loop. Not a for cursor loop.
