Events in SM30

Hello Everyone,
I am trying to restrict the value of a field in SM30. The idea is the value of this field cannot be duplicate. Also, I can't make it the key field as there can be only 1 key field in the table.
Let me be more clear. The field name is 'Priority'. If the value of field is entered as '1', then in the next record the value of priority can't be '1' again.
I am trying to create an event for this, but I am not clear with the concept of TOTAL & EXTRACT. Can some one explain me the same.
Please do not refer any links as I have thoroughly searched SDN and SAP help and they are not of any use. I have read each and every document available for events on SM30 and didn't find anything related to my query.
Regards,
Snehal

Solved it on my own........
Thanks everyone.

SM30: table Maintenance - appropriate event while changing existing entries

Can anyone please let me know which event is appropriate to validate data while changing existing entries in database table using SM30.
Thanks & Regards,
Nilesh Kumar

Hallo,
You have to create two events for sm30.
05 FETCH_VALUE_NEW
21 FETCH_VALUE_CHANGE
The first event-05 triggers when you create new entry where you can update created by/created date etc.,
and in the second event-21 you can update Changed by/Changed date.
Please let me know if you need any further information in this regards.

Event for preventing a new entry in DBTable

hi all,
please suggest me a event in table maintenance to have a check for preventing the entry into the table. i tried event 18 but wen the error msg is displayed it comes out of record entry window which is to be avoided.
regards
Madhu

My friend it is not
18 . it is 05 -> Creating New Entry.
so that you can validate with the User and do the validation and update the table .
"Below is the code for it
Select 05 for an event for Creating a new entry.
This event will be triggered while creating a new entry in SM30 or using the TCODE.
Form Name: AT_NEWENTRY (Enter key)
Double Click on the editor.
form at_newentry.
Ztab-ZCOUNTRY = India.
Ztab-ZCREATEDATE = sy-datum.
Ztab-ZCREATETIME = sy-uzeit.
endform.
Create another event: 02 for After Save
FORM after_save.
Ztab-mandt = extract+0(3).
Ztab-ZCOUNTRY = extract+3(3)..
Ztab-ZCREATEDATE = sy-datum.
Ztab-ZCREATETIME = sy-uzeit.
MODIFY ztab.
ENDFORM. "after_save
Step 4: Create Transaction Code.
Go to SE93.
Transcation code: ZTAB
Transaction text Test Table Maintenance Events
Transaction: SM30, Skip first Screen
Default Values:
VIEWNAME ZTAB
UPDATE X

Any idea where to set the default value on a field in the table control or in the maintenance view.

Validations in MAintainance View

HI all,
I have assigned a Tcode to a maintainance view..So when i insert a new record , i want to check if a primary key field is left blank while saving or if all fields are blank while saving. In these cases it should not save. So what do i do? another validation requires to check if the start date is lesser than the end date.. IS this possible without having to create a new module pool or anything similar? if so how? Is it possible using Events in table maintance generator? CAn u please give me the detailed steps?
thanx,

Update a table Z using SM30 events

Hi experts,
I've been told to do the following:
I have a table ZYOPER that the user can modify through a SM30 (actually by another transaction that calls the SM30).
Now they want every time you update/create/delete a record in this table ZYOPER, save a log in another table ZYOPERLOG indicating the action completed and the data contained in these records.
I implemented the following events but it's not fine...
- 03 (new entry, field ZYOPERLG-action = 'INSERT')
- 05 (delete entry, field ZYOPERLG-action = 'DELETE')
- 02 (Modify the new table ZYOPERLOG)
The issue is that in the 02 event I have tables Total and Extract, which are all the records contained in ZYOPER even if they have been modified or not. Can I do it with import and export? Is it possible to declare a global internal table i_zyoperlog in order to keep the records updated/deleted/created ?
Thanks in advance...
Mary

Your requirement is a good use-case for [Event 01: Before Saving the Data in the Database|http://help.sap.com/saphelp_nw04s/helpdata/en/91/ca9f0ba9d111d1a5690000e82deaaa/content.htm].
Why do you need this custom table anyway? You can set the "log data change" setting & evaluate it via trxn SCU3.

How to carry out entry validation in SM30 with events

Hi people,
I'm creating a Z table with Maintenance view in SM30...i've modified the view so all fields are required as Rich H explained in some other post. But now i need to validate user input for a particular field against a standard table, and force to reenter if data is not valid. I've been looking up the available events...event 05 triggers when the line is new, but not when modifying. I've tried a couple of other events but don't serve my purpose. What i want is to validate data upon user's entered all the required fields (whether the line was preeexistant or not). If data is valid then go on, if not trigger a message and force correction prior continuing (disallowing saving).
Anyone knows how to do this?
Many thanks

I get what you suggest, but unfortunately i've already done that, it's not enough.
Here's the situation: The table has this fields:
KSCHL (PK-FK T685)
LIFNR (PK-FK LFA1)
EBELN (FK EKKO)
EBELP (FK EKPO)
Besides the implicit foreign key validations (i.e. the PO item exists in EKPO), i need to validate that it's not deleted (LOEKZ = 'L') and that the PO vendor is the one entered (i must not enter any PO which vendor isn't the one in that line). Hope I make myself clear.
This code works but in event 05 (new lines). I need to find out an event for the modified lines as well:
FORM f_validate_po.
CHECK NOT ( ztmmiv001rps-lifnr IS INITIAL OR
              ztmmiv001rps-ebeln IS INITIAL OR
              ztmmiv001rps-ebelp IS INITIAL ).
SELECT COUNT(*)
FROM ekko
WHERE ebeln = ztmmiv001rps-ebeln AND
        lifnr = ztmmiv001rps-lifnr AND
        exists ( SELECT *
                 FROM ekpo
                 WHERE ebeln = ztmmiv001rps-ebeln AND
                       ebelp = ztmmiv001rps-ebelp AND
                       loekz <> 'L' ).
IF sy-dbcnt = 0.
    MESSAGE e000.
ENDIF.
ENDFORM.

SM30, events and custom code.

Hello friends,
I have the following requirement. There is a custom Z table and there are 4 fields inside the table. When i change a field, i have an event before_save_database, where i go and update the value of the 4th field if field 3 changes. On display it shows data was saved although the 4th fields still has the old value.
Only when SM30 is entered is the new value for field 4 seen.
I want it to display the new value in the first run itself when the message comes 'Data is saved'. Kindly mention how the following can be achieved.
Regards,
Jaydeep.

i´m not a 100% sure that i got your requirements, but i think it´s a commit problem.
if you enter SM30 you have a dynpro change, which means you loose your dialog work process.
This again leads to an implicit commit on your DB.
now i would try to do an manual commit and see if your problem still exists.

I did a COMMIT WORK also before the save in the database, but the changed values get reflected only in the next opening of the SM30 screen.

hi friend,
i face the same problem once, it is purly depend upon the keyfields, in your Z table put 4th field as a key field and adjust the data base or regenerate that function group and try once..
i think it is very help ful for you

Table Event - SM30 - Entering into transaction

Hi All,
Before posting this message I looked for a solution in the forum, but from the messages I found none of them has what I need.
I would like to know which event code I have to use to update a field in a table in SM30 when entering it.
Thanks in advance!
Robson

Seshu,
Thank you for your reply, but doesn't work.
I have a table with 2 fields: Code and Description.
I need when entering in transaction, before display data on screen, an event update Description based on Code. The event 01 is not called at this moment. I've found events 19 and 25, but inside them, data still not charged in table.
Thanks,
Robson

SM30- EVENTS in Table maintanance

Hi All ,
I have created a table maintainance for my Ztable . User wants the EXCEL button to down load the data into excel .Hence , I was able to Give the EXCEL Button in Application tool bar of table maintainance GUI which is copied from Standard one .
But what is the correct EVENT to code the functionality of downloading into excel? . Please adivise me on this . How can i make use of the events insated of Changing in the PAI modules .
Please revert me if you need any other info to understand the issue ...
Thanks in advance ,
Dharma .

Hi Dharma,
Your requirement is a functionality of downloading the list of entries to EXCEL. This is not a standard View maintenance Event offered. Events, are usually called when a particular step/process is triggered. In your case, the requirement seems like the download to Excel can be executed at any point of time on the screen, right?
It is therefore perfectly ok to simply add a button on your screen, and modify the PAI to include the action specifier for your new button. While implementing this PAI, just make sure you do not write it into the standard View Maintenance Generated includes. Use a seperate one for user-modifications.
If you are very specific about using an EVENT, then you could go for ST - which is a GUI menu main program. But using this just for one extra button is not really necessary, but you could decide.

Rekha

Modify records with SM30 events.

Hi,
I try to modify one record using SM30 even 01 (before save). When the user add new record and push the save buttom, I need to modify the previous record in the table. I try to modify a key field (end date of validate). This is one example:
Records in table:
Init date of validate    End date of validate    Value
01.01.2008                 31.12.2008                1
The user add new record:
10.01.2008                   31.12.2008               2
I need change the first record, and the final result must be this:
Init date of validate    End date of validate    Value
01.01.2008                 09.01.2008                1
10.01.2008                 31.12.2008                2
Thanks for yours replys.

I was just reading your first post and observed that you mentioned
"_I try to modify a key field (end date of validate). This is one example_"
Does this means that you are trying to modify a field that is part of table primary key? If yes, then please note that primary key fields cannot be changed. The only way is to delete that row and insert a new one with different value.
However if the fields you are changing are non key fields (not part of table primary key) than following can help you.
Have a look at the code here.
http://help.sap.com/saphelp_nw04/helpdata/en/91/ca9f0ba9d111d1a5690000e82deaaa/frameset.htm
Now suppose your table name is ztable with following fields
MANDT
FLD1
FLD2
SDATE
EDATE
So you will declare a work area like
data: begin of wa_total.
INCLUDE STRUCTURE ZTABLE.
INCLUDE STRUCTURE VIMTBFLAGS.
data: end of wa_total.
Now basically work area wa_TOTAL will have a structure like
MANDT
FLD1
FLD2
SDATE
EDATE
VIM_ACTION
VIM_MARK
VIM_TXTACT
SO the scenario you defined in your first post, where row 1 is already in table and row 2 is added, row 2 will have value N in vim_action field.
to update row 1 you will do something like
read table total index 1.   "1 is the row number to be changed
if sy-subrc = 0.
move total to wa_total
wa_total-edate = "enter new date here
wa_total-vim_action = 'U'.
modify total from wa_total.
endif.
similar logic for "EXTRACT"
I hope this helps.

Need to validate a existing field in the table maitainence Generator events

Hi EXPERTS,
There is one Z-table and for that TMG also there. There is custom transaction for sm30. Now I need to validate one field BNAME for new entries I have created event -05(creating new entry) it is validating correctly. But now another requirement is if user also wants to change the existing values for the field BNAME it should also be validated needs to populate error mesg and does not allow to save it. I used event 01(before saving data) 07 ( before correcting the contents of selected field) 18 ( after checking whether data has changed)but not working any of these events. Please suggest me which event is suitable for my requirement. Orelse I need to put the code in the flow logic of the screen under PAI module I think this is not a good practice.
Code:
FORM data_changed.
DATA     : l_bname TYPE xubname.
CONSTANTS: c_mesg      TYPE char16   VALUE 'Invalid SAP User',
             c_error     TYPE char1    VALUE 'E'.
* Validation on BNAME field
IF zps_capex_appr-bname IS NOT INITIAL.
    SELECT SINGLE bname FROM usr01 INTO l_bname
           WHERE bname = zps_capex_appr-bname.
    IF sy-subrc NE 0.
      MESSAGE c_mesg TYPE c_error.
    ENDIF.
ENDIF.
ENDFORM.                              "DATA_CHANGED
Please suggest me how to proceed.

Edited by: Rob Burbank on Mar 2, 2012 9:23 AM

Hello Sreekanth,
How are you populateing the field zps_capex_appr-bname ? I'm pretty much sure that this is not getting populated at runtime.(put a break-point & check)
In order to access the data in the TMG [Event01|http://help.sap.com/saphelp_nw04s/helpdata/en/91/ca9f0ba9d111d1a5690000e82deaaa/content.htm], we have to use the TMG system tables - TOTAL & EXTRACT.
If your validation of BNAME fails, remember to:
1. Set SY-SUBRC to a non-zero value,
2. Set the flag VIM_ABORT_SAVING to 'X'.

Suhas
