Activate Standard Enhancement using Enhancement Spot

I am trying to activate Standard Enhancement objects provided in the Standard Transactions, but unable to activate it.
Can u pl. share any documentation through which i can use standard code by modifying at predefined enhancement spots.
Like in transaction "WPS1" it call function module MEB_FUNC_ACTIVE
FUNCTION MEB_FUNC_ACTIVE.
""Local Interface:
*" EXPORTING
*"     REFERENCE(E_MEB_ACTIVE) TYPE C
Set the export parameter 'e_meb_active' to blank means: deactivation
e_meb_active = ' '.
ENHANCEMENT-POINT MEB_FUNC_ACTIVE_01 SPOTS ES_SAPLDIMP_PROXY.
$$-Start: MEB_FUNC_ACTIVE_01----
$$
ENHANCEMENT 3 AD_GENERAL_SAPLDIMP_PROXY.    "active version
Set the export parameter 'e_meb_active' to 'X' means: activation
BREAK-POINT.
e_meb_active = 'X'.
ENDENHANCEMENT.
$$-End:   MEB_FUNC_ACTIVE_01----
$$
ENDFUNCTION.
There are predefined Enhancement spot which are not active so how can i activate the same.

Hello,
Any enhancement related to Model/Service Implementation which includes adding of custom code/manual code, then it has to be done in MPC_EXT & DPC_EXT class.
The reason is when ever u change the Model or Service implementation in your GW Service builder, again run-time object should be regenerated in-order to incorporate the new changes.During this time your MPC & DPC will be loaded with the new code.If at all if u had any manually written code directly in MPC/DPC then that code gets over written with the new code.
So changes to be done always in MPC_EXT/DPC_EXT classes.
I do not see any blog as such about the topic u r asking, its just that u need to do necessary declarations, redefine the appropriate methods and add ur custom code to enhance the standard code generated by service builder.

How to use Enhancement spot in program

Hi gurus,
now i am working ecc 6.0, so how to use Enhancement spot in program, can anybody explain step by step.
Rewarded with points.
Thanks
Naveen

Hi Naveen ,
Enhancement Spot are available.
Examples:
-End of Executable Program, Include, Function group, Dialog module
-Begin/End of Form routine / Function module / Method
-End of a structure
-End of Private/Protected/Public Section of a local class
If you want to create Implementation , You have to right click on yellow color line and gve Zxxx and save it in any
transport request under any dev class. Then you can write your own code and save it and activate it .
Later If you want to Transport it you need to transport this request.

Hi Experts,
I am using userexit_move_field_to_vbap enhancement spot.

I am getting dump. I want to know how to update a standard table in enhancent spots. Here i am tring to update XVBAP-ABGRU with ZP for the corresponding sales order.
Please help me <removed by moderator>.
Thanks&Regards,

In this user exit you should change the field values of structure VBAP,not internal table XVBAP.
VBAP-ABGRU = 'ZP'.
See the Userexit comments
This userexit can be used to move some fields into the sales *

Hi Henry,
I don't think this is the easiest way to look at the code around a particular field on the screen. Debugging standard programs also can be very tedious, if not impossbile. So, instead of this question, I would like to find out exactly what you want to do if you know the code.
If you are in a transaction and you want to know where the code of a particular field is, the fastest way to get to it is by pressing the F1 key on the field and then press the Technical info button on the help screen. In here you will typically see the same kind of information but it is very specific to the field you selected.
PROGRAM(SCREEN) tells you which program is manipulating the main screen, in which your field is embedded. Remember your field may be included in a sub-screen and that subscreen may be the one included in the main screen.
PROGRAM(SUB SCREEN) tells you which program is directly responsible for the field on the subscreen it is included in. This is where you should find the code most appropriate for the field, but not necessarily.
PROGRAM(GUI) controls how your push buttons and the menu options in the screen behave and controlled.

How to use Enhancement Framework in ECC 5.0 and 6.0

hi
is there any good tutorials on enhancement framework? i have gone through the help but its not very clear. if anyone has stepby step guide will be useful.
~Suresh

This is an old question... but i think it is very useful for the developers if anyone search it and find my answer relevant like it with immediate effect.....
What is Enhancement Framework?????????
Enhancement Framework is the new paradigm to bring all enhancement techniques under one roof. It can also be switched using Switch Framework. The following are different enhancement technologies available under this framework.
• Source Code Enhancement
• Function Group Enhancement
• Class Enhancement
• Kernel-BADI Enhancement
Semantically related enhancement options are grouped under a ‘Simple Enhancement Spot’. ‘Composite Enhancement Spot’ contains one or more of Simple and other Composite Enhancement Spots. On the other hand (implementation side), various related implementation elements are grouped under a ‘Simple Enhancement Implementation’. A ‘Composite Enhancement Implementation’ can contain one or more of Simple and other Complex Enhancement Implementations.
1.Source Code enhancement
Whenever enhancement needs to be incorporated directly into the ABAP source code, this technology shall be provided. Implementing this technology is also called as Source Code Plug-In. There are two types of Source Code enhancements possible.
• Implicit enhancement option
• Explicit enhancement option
>>>Implicit enhancement option
Throughout the ABAP system, enhancement options are automatically available at certain pre-defined places. Some of the implicit options are:
• At the end of all the programs (Includes, Reports, Function pool, Module pool, etc.), after the last statement
• At the beginning and end of all FORM subroutines
• At the end of all Function Modules
• At the end of all visibility areas (public, protected and private) of local class
******Note that, in order to implement any of these Source code enhancements, you need to be in the ‘Change Enhancement mode’ (the spiral icon available in the editor). Technically the source code plug-in implementations are stored in a separate include program and not as part of the original source program.***********
>>>>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 – called Enhancement Section. For this, we now have two new ABAP statements, viz.
• ENHANCEMENT-POINT
• ENHANCEMENT-SECTION
When the Enhancement-Section is implemented, only the implementation gets executed and the original code doesn’t get executed. This is a new technique, which didn’t 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.
we mainly use above framework .......if nybody need further and more information let me knw...

Using enhancement COPA0001 in a derivation to clear value fields

Dear colleagues,
In our sales process, freight is added as an item of the sales order, which means we maintain different freight types as materials (mat type ZFRE - "Freight") and we create cost estimates, so that this cost can be valuated into COPA.
Our problem is that we do not want to capture the cost of goods sold and the cost of sales for those materialss, as they only represent the freight cost that is paid by us and reimbursed by our customers. In addition, I we would like to move the value of the revenue value field to another value field (Freight sales).
I am trying to accomplish this by using enhancement COPA0001 - I created an enhancement step and I added a code to include ZXKKEU11 which specifies the "clear" of 2 value fields and the "move" of the revenue to another value field.
I had done this in the past to clear quantity fields, but I am testing this new config and it doesn't work.
When testing the derivation analyzer tells me that "Derivation was not carried out. Reason: None of the target fields are to be derived".
I looked in the known resources, but couldn't find any valuable information about such an issue. I did see in the SAP library that target fields can be "All quantity unit fields" , but value fields are not mentioned.
Did anyone have a similar experience or knows if what I'm trying to do is possible?
Thanks,
Yoel.

Hi
You can try with exit COPA0005 as Christian mentioned...
But, I would like to know your process in ddetail to see if any standard mechanism is possible...
1. What does your sale order look like? Does it has one saleable material + Multiple freight materials?
2. What purpose these freight materials serve? Do they have a revenue as well as cost in the sale order pricing procedure?
3. Can you explain your total scenario with accounting entries? and what exactly are you looking at

basham,
You didn't mention which type of DBMS you are using (i.e. Oracle, MS SQL, MySQL, etc), but in a nutshell using MS SQL here is the principle. Your time that is recorded in the records is dependent upon a setting in your RDBMS. For instance, the RDBMS can use the machine time (which would most likely be local time), or it can use the machine time with an offset (to accomodate GMT, for instance). GMT is factored differently based upon your time zone (and time of year, i.e. DST or EST, etc). I'm on the east coast so right now my offset is GMT - 5, so if my time right now is 1457, then GMT is 1957. To get SQL to compute an offset you must take the number of hours to offset and divide by 24 (24 hours in a day) and add that to the record in the database. For instance, to get GMT right now I would use:
select cast(getdate()5/24. as char(12))rtrim(convert(char(12),getdate()5/24.,8))' GMT'
Hope this helps. If you're on Oracle, then the mathematical principles remain the same, just the formatting will be different.

Does SAP activate some user exits (enhancements) implicitily?

Hi Gurus,
    The situation is:
    I'm using the enhancement QQMA0025, which has the user exit EXIT_SAPLIQS0_017. Well, I created code in the user's exit include (ZXWOCU21). Activated the include and the user exit and it executes correctly.
    What seems strange to me is that there is no project in CMOD which has the enhancement QQMA0025. So, the user exit should not execute (but it is still executing).
    And here comes the question of the subject: "Does SAP activate some user exits (enhancements) implicitily?"
    If yes, explain me how to find them and so on.
    Thanks a lot in advance.

I've looking for the answer.
I don't know if it is 'ja' oder 'nein' but I pressume that is yes.
I have found a table TFDIR, which has a field MAND that tell us if a user exit is active. How?
If MAND has value 'C' then that user exit is active. The user exit is identified by the FUNCNAME field.

How to make a view created using enhancement framework as Interface View

Dear Experts.
I Created A new View and window by using Enhancement Framework for a standard webdynpro comp. Now i want to use the same window as a UIBB in FPM , since in window properties interface view check box is unchecked it's not allowing me to use a UIBB in FPM.
Kindly answer for the following.
1) Is there any way to make a view a interface ( whcih is by default in nature but while creating from Enhancement framework behaivng Strangly).
2) If there is no way then how to use enhanced (additional View Created in Standard WDA comp) further like in FPM ( UIBB ).
thanks in Advance.

Hi,
Please see [https://cw.sdn.sap.com/cw/docs/DOC-21546|https://cw.sdn.sap.com/cw/docs/DOC-21546]
windows created through enhancement are local to component and hence they are not visible outside.
You need to find other way to provide your interface view to UIBB.

Enhancement using Business Data Toolset

Hi All,
We are making use of BDTs to enhance SAP Standard Screen for which provisions exist for enhancements using BDTs.
We need the funtion modules ie GET and COLLET funtion modules to tranfer the data on the screens to the Database tables
for example we know GMG_GMGT_GMGR_GET
GMG_GMGT_GMGR_COLLECT
funtion modules to transfer data on customized fields to the Data base tables.
Simillarly we want to suggest the procedure to find that those function modules for other BDT enabled transactions.
HELPFUL ANSWERS WILL BE REWARDED.

Hi Kiran
1...As far as i know, Through BDT we cannot change the name of the existing field.
But using SE63 u can change the Field name, provided the standard dialoug program is refering directly to the Dictionary object for the Field Label. Basically the SE63 is a Translation Environment, where you can change the Field Label.
2...Including New field can easily be done through BDT.
Step1...Add a field in the Customer include CI_VIBDPR of table VIBDPR
Step2...Create a function group and create a Screen for that function group trhough SE51 and include the above field in that.
Step3....do the process for adding the field group, View , Section , and Screen through you BDT Transaction.---Any problem in any step, let me know.
I have done this quite a few times for Business Partner.
3....For his problem i will let you know in a day or two. But the Logic is similar to above.

Can I Using Enhance Receiver Determination?

Hi,
Can I used Enhanced Receiver Determination to push data to Receiver 2 , based on the response coming from Receiver 1 ( a BPM that that has a synchronous send step and fetches response from SAP through a proxy) ? If yes, how ?
thanks & regards,
XA

We can have just a send step and for that send step we can configure a condition based receiver Determination right?
yeah correct
> and Can you throw some light on how to deal with queues, in case if the response doesnt come from SAP to PI due to some reason, which can happen in real time?
it will thhrow time out exception or message expired exception, if you want to do exception handling do it accrodingly using Control step.

Changing the name of the tab created using enhancement MM06E005

Hi,
Is there anyone know how to change the name of item level tab from "customer data" to our own tab name in screen exit for trans ME21N/2N/3N? Enhancement used is MM06E005.
And is it possible to show or hide the newly created tab using enhancement depending on the data displayed in tab? If so how?
Any help will be appreciated.
Regards,
Naveen

I came across the same issue as well a while ago, see my thread at Can you programmatically change the iView Title?
No one could answer my question properly, so I decided to go the DHTML route; find the <DIV> element encapsulating the proper iView title, and then replace the innerHtml with the new title.... Ackward, I agree, but it works
It's java based, but the actual replacing is all DHTML, I will look up the code and post it

Problem with SRM Business Partner enhancement using EEWB.

Hello Gurus,
I am doing Business Partner Enhancement using EEWB. basically adding new tab with few data fields. After using EEWB, the new tab hasbeen generated automatically and BP is creating successfully and data is stored in tables.
But in the custom tab, the fields are displaying in table format after using EEWB. User dont want in the table control, and they want normal screen fields.
How can we do that. After that, will it reflect to portal automatically or do we need to do any thing?
Pls suggest me.
Regards,
Ram

Hi all,
I used EEWB to enhance BUT000 wiht a new field and a new tab.
How can I show them in SRM7?
BBPMAININT has been replaced with an "equivalent" WebDynpro application and old Badis are not supported anymore.
any ideas?
thanks in advance.
