Customer exit for validation of PO fields in ME21N / ME22N - After pressing enter & save button

Hi,
I am looking to validate the standard fields(EKKO-IHREZ, Your reference under communication) of Purchase order . So for this I used the customer exit EXIT_SAPMM06E_012 under the enhancement MM06E005 . I am able to validate but it is triggering only when SAVE selected.
1. Can we implement the same when we press enter button ?
2. How to log error message using macro for the field EKKO-IHREZ with error message ? As of now I am using message 'asdfasdfasdf' type 'E' which is appearing now in the log messages.
Regards,
Praveen CHITTURI .

Better use methods like PROCESS_HEADER or PROCESS_ITEM of BAdI ME_PROCESS_PO_CUST.
There are many threads and documents on this BAdI at scn.
In the chosen methods use Macros mmpur_metafield to attach error to a field (defined in type-pool MMMFD, mmmfd_ref_1 ?) and mmpur_message_forced to raise error message and add it to log.
include mm_messages_mac.
im_item->invalidate( ).
mmpur_metafield mmmfd_matnr.
mmpur_message_forced 'E' 'ZFSM' '613' ls_item-matnr ls_item-werks ls_header-bsart ls_material_plant-mmsta.

User Exit for validating overall limit field and expected limit field-ME2xN

Dear Gurus,
Can you please suggest me any user exit or BAdi to validate the overall limit field and expected limit field in transaction ME2xN.
Or any other way to to achieve this functionality in ME2xN.
Our Requirement is while raising a service PO in the Limits tab the 'Overall limit' should be same as 'Expected Value', at present the user can enter overall limit greater than 'Expected Value'.
Regards,
Priyank Joshi

this will not work. you cannot add another structure (AUFK) on top of CEBAN. all characteristics have to be of one structure and since you want to release a PR it has to be CEBAN. before attempting to program something around that why do you not go to tx. OLME -> PR -> Release Strategy -> With Classfication -> Release Strategie and run it in a simulation mode. you will then see how it reacts.
there's a white-paper on service.sap.com explaning in detail release-strategies. it's a good one and a good read too!

How to select data from an aggregate in a customer exit for a query?

Hi,
I have written a virtual key figure customer exit for a query. Earlier the selection was from the cube, where there was severe performance issue. So I have created an aggregate, activated and have loaded the data.
Now when I select that data I find that the Key table is different in development and production. How do I resolve this.
My code is attached below. The table in developemnt is KEY_100027 and in production is KEY_100004. This code is activated and running in BW development server.

How do I transport the code and make it work?
Whats the reason that the two key fields are different.
I had transported the aggregate from development to production. Activated it and filled the data.
What is the way out? Please help.

Hi Sonu,
The main task is to move the contents of the one internal table to another with some condition.
First sort and delete the duplicate entries from the First Internal table like below :
sort it_tab by material ascending date_modified descending.
delete adjacent duplicates from it_tab.
Then move that Internal table contents to another internal table.
Define another internal table with the same structure as you have first internal table and then
Second Step :
it_itab1 = it_itab.
If you are using seperate Header line and Body then you can do like below :
       it_itab1[] = it_itab[].
This will fix the issue.
Please let me know if you need any further explonation.

Kittu

Custom Exit for determining previous-year time range

Dear all:
I have a problem about custom exit:
We have created a new object for combining Fiscal Year/Month and Period. So the format will be shown as " yyyymmp"
now we have one requirement which is determining the same period but previous year based on user input. For Example, if user input start and end period as
"2006041" and "2006111". There are should be 2 custom exit which are able to convert the user input to be "2005041" and "2005111". We created 2 custom exit for telling the previous-year period.
Then based on this converted time range, we should be able to extract applicable data. But after testing, we cant get supposing result. The code is following:
We will be very grateful for any input. thank you all so much

Hi,
Try with following modifications:
ZYEAR1(4) = LOC_VAR_RANGE-LOW(4).
ZYEAR1(4) = ZYEAR1(4)- 1.
ZMONTH1(2) = LOC_VAR_RANGE-LOW+4(2).
CONCATENATE ZYEAR1(4) ZMONTH1(2) INTO LOC_VAR_RANGE-LOW(6).

Problem in creating include program for customer exit for BC425_01

Hi,
I want to write a customer exit for transaction BC425_01. For identifying the include program for exit , i go to System->Status.There I double click on the program name(GUI).Then I perform a 'FIND' in main program for 'customer-function' keyword. I get 3 search results with "CALL CUSTOMER-FUNCTION '001' " , "CALL CUSTOMER-FUNCTION '002' " , "CALL CUSTOMER-FUNCTION '003' ".
Now i double click on CALL CUSTOMER-FUNCTION '001' and i am taken to the code of program where this function is called in MODULE cust_check INPUT. I double click on CALL CUSTOMER-FUNCTION '001' and then I am taken to the function module code which contains a single statement 'INCLUDE ZXBC425G01U01 .' .
Now I double click on this include program so that I can write my own code. But when i double click on it , a message displayed 'Program names ZX.. are reserved for includes of exit function groups'. Hence I am not able to creates this include program and write my coding.
Kindly Help
THANKS

Hi Amber,
Then you click enter button.It is asking to create object with that include name ZXBC425G01U01 in a pop-up.You should select YES option.It will ask package . Give the package name and save.Then include program is created and allowed you to write your own code.

How to find out query name in customer exit for variables

We use the same customer exit variable in different queries. In the customer exit we want to find out, which query has called the customer exit. With the technical query name we want to read a master data table entry.
e.g. If we come from query ZG1_TEST1 we want to use selection sel1
Query name | selection
ZG1_TEST1 | sel1
ZG1_TEST2 | sel2
How can we find out the query name in the customer exit for variables?
Thanks for your help,

Hi Evi,
check out the structure I_S_RKB1D in your exit. It contains the query.

Customer Exit for Calendar Month based on the day (system Date)

Hello,
I need help in creating a customer exit for Calendar month without the user input. The logic is as follows:
For the BEx variable created with customer exit option and no user input:
If the day on the system date falls in between 1 to 14 take the calendar year/month value as previous month.
If the day on the system date falls in between 15 through 31 then take the calendar year/month as current month.
eg if report is run on March 24th2009 the calendar year/month variable should be calculated as 03/2009 (March 2009)
if the report is run on March 1st2009 the calendar year/month should be calculated as 02/2009 (Feb 2009).
The code should be effective when run in the first 15 days of Jan when the previous month would contain the previous year as well.
Thank You
Srishti

Thanks Shanthi. I am trying to incorporate the logic when the query is run in beginning of Jan when the year should be the previous year.Following is the code.please let me know if it would work. Is there a way I can test it as well?
CASE I_VNAM.
WHEN 'ZCURCALMON'.
IF i_step = 2.
data: mm(2),
        dd(2),
        yy(4),
        FM(6).
if sy-datum+4(2) EQ 1.
sy-datum(4) = sy-datum(4) - 1.
else.
sy-datum(4) = sy-datum(4).
endif.
if sy-datum+6(2) LE 15.
mm = sy-datum+4(2) - 1.
concatenate sy-datum(4) mm into FM.
else.
concatenate sy-datum(4) sy-datum+4(2) into FM.
endif.
l_s_range-low = FM.
l_s_range-sign = 'I'.

How to find CUSTOMER EXIT for a Standard SAP program

How to find CUSTOMER EXIT for a Standard SAP program

Hi
To introduce the techniques of enhancement in standard SAP system. SAP creates customer exits for specific programs, screens, and menus within standard R/3 applications. These exits do not contain any functionality. Instead, the customer exits act as hooks. You can hang your own add-on functionality onto these hooks.
They do not affect standard SAP source code.
When you add new functionality to your SAP System using SAPs exits, you do not alter the source code of standard SAP programs in any way. The code and screens you create are encapsulated as separate objects. These customer objects are linked to standard applications, but exist separately from SAPs standard software package.
They do not affect software updates.
When you add new functionality to your SAP System using SAPs exits, your objects (called customer objects) must adhere to strict naming conventions. When it comes time to upgrade a to a new software release, customer objects names ensure that they will not be affected by any changes or new additions to the standard software package.
Customer exits are not available for all programs and screens found in the SAP System.
Any change made to an SAP object in a customer system is called a modification. Customers usually modify their systems for one of two reasons. Either they make changes to the SAP standard in order to adjust the R/3 System to their specific business needs (actual modifications), or they alter individual SAP objects in order to correct an error (as recommended in an SAP error note).
You should only modify the SAP standard if the modifications you want to make are absolutely necessary for optimizing work flow in your company. Be aware that good background knowledge of application structure and flow are important prerequisites for deciding what kind of modifications to make and how these modifications should be designed.
SAP application programmers create SAP enhancements in transaction SMOD using function module exits, menu exits, and screen exits.
Customers are given a catalog containing an overview of existing SAP enhancements. They can then combine the SAP enhancements they want into an enhancement project using transaction CMOD.
SAP enhancements are made up of component parts. These components include function module exits, menu exits, and screen exits. A specific component may be used only once in a single SAP enhancement (this guarantees the uniqueness of SAP enhancements).
Customer enhancement projects consist of SAP enhancements. Each individual SAP enhancement may be used only once in a single customer enhancement program (this guarantees the uniqueness of a customer project).
SAP application programmers preplan function module exits, menu exits, and screen exits for their applications and combine them to create useful enhancements for the R/3 System.
Customers create their own enhancement projects for their systems using SAP enhancements. You can customize the individual components of an enhancement project by creating your own include programs (for function module exits), texts (for menu exits), and subscreens (for screen exits).

Customer Exit for 13 month from current month

Hi Gurus,
I need a customer exit for 13 months from current month. Based on the requirement I have written following code
When 'VPI_13CALYRMON'.
    IF i_step = 1.
      l_s_range-sign = 'I'.
      l_s_range-opt = 'BT'.
      l_s_range-low = sy-datum+0(6).
      l_s_range-high = sy-datum+0(6) + 13.
      append l_s_range to e_t_range.
    endif.
Please could you guide me the code.
Thanks
Ganesh Reddy.

Hi,
I think you can do it in below way.
When 'VPI_13CALYRMON'.
IF i_step = 1.
temp1 = sy-datum+0(4).
temp1 = temp1 +1. (because adding 13 months would take year to next year)
temp2 = sy-datum+4(2).
temp2 = temp2 + 1. (after adding 13 months, the month would be one more than of previous year)
concatenate temp1 temp2 into temp3.
l_s_range-sign = 'I'.
l_s_range-opt = 'BT'.
l_s_range-low = sy-datum+0(6).
l_s_range-high = temp3.
append l_s_range to e_t_range.
endif.
Hope this helps.

How to find the customer exits for a particular transaction

hi
how to find the customer exits for a particular transaction

Hi jyothsna vankadari ,
ther is a convenient way to find all BADIS called. You may know that BADIS are the newer version of EXITs.
I would suggest you to go for BADI.
Follow the below steps to find out what all BADI's are called when you press any button in any transaction.
1) Goto se24 (Display class cl_exithandler)
2) Double click on the method GET_INSTANCE.
3) Put a break point at Line no.25 (CASE sy-subrc).
Now
4) Execute SAP standard transaction
5) Press the required button for which you need to write an exit logic, the execution will stop at the break point.
6) Check the values of variable 'exit_name', it will give you the BADI name called at that time.
7) This way you will find all the BADIs called on click of any button in any transaction.

Clemens
