Validation of entry in custom table

Hi ppl,
I have one requirement where users can maintain value into a custom table. While entering a new value, if the similar primary key entries already exist in the table then there is a requirement of giving a pop-up box to the user informing that a similar kind of entry already exist and if he wants to overwrite. If the user clicks yes, then the new record should be saved and also one of the field in old record should be modified.
I have written an event in the table maintenace by which i am able to get the pop-up and the old entry gets modifed but when the PBO module gets triggered inside a standard include i get the error mssage " Record already exist". The error is obvious as the same primary keys are used in the second entry too but i am just curious to know if there is any way by which this standard error could be overcome so that the user should get only my pop-up box and not the standard error message.
Regards,
Venkat

hey,
You are getting the standard text because you are going to insert into the table.You cannot suppress the standard message but you can do some other thing.You take the values in the table to the internal table and before insertion into the table you should check the value which the user had entered and then check the value and the key.Thus you can catch that before the insertion into the table.
You can use the READ statement with key for reading the database.if the sy-subrc is 0 you can understand a value is there in the table.
Hope this will be helpful.

Insert delete or update entry in Custom table from KONV entry changed

Hi All,
I have custom table ZKONV with only few required columns and should have same number of records as KONV has at any point in time.
KONV is a cluster table so its not readable from ORACLE level. So ZKONV is created. But I dont know how to keep these both tables in sync.
I need to perform insert delete or update entry in Custom table if insert delete or update happens on cluster table KONV from any transactions.
As KONV is a cluster table and does not have changed time stamp I am not able to know the number of records changed in perticulat time period.
Thanks,

Thanks for reply,
There is a Outside SAP system which needs to read KONV data to feed into their system, but as KONV is cluster table they are not able to read it from ORACLE level.
To solve this we are thinking to create a transparent Z-table and will fill it with KONV and catch Update, delete or Insert statement and do same on ZKONv.
Is this possible some how? by some database event or something....

Unable to delete last entry in Custom table

Hi,
I have one custom table which allows only some specific entries to be maintained in the table.I have used a standard table as a check table for dis.I found no issue while maintaining entries in the table.But when i try to delete the last entry in the table i get the message "No entry exist".Long textNo entries were found when importing data from the database.
Kindly help.

Hi,
If it is not possible through table maintainence then write a small Z program to delete the entries in devlopment system and then if then if you want you can transfer those to other systems.
delete from ZTABLE where {give your condition for the last record}.

req output:::when i enter doc_name the related info accr to doc_name from the both tables should be display..
m getting no errors but i cant execute my prog..
please check out my code...
thanx in adv..

Hi,
The problem is in the select statement:
SELECT DOC_NAME
PATIENT_NAME
PLACE
ZDATE
MEDICINE
PRICE
QUANTITY FROM ZPATIENTL_INFO INTO TABLE t_pi FOR ALL ENTRIES IN
t_hi
WHERE DOC_NAME = t_hi-doc_name.
Change this to SELECT DOC_NAME PATIENT_NAME PLACE ZDATE MEDICINE PRICE QUANTITY FROM ZPATIENTL_INFO INTO CORRESPONDING FIELDS OF TABLE t-pi FOR ALL ENTRIES IN t_hi WHERE DOC_NAME = t_hi-doc_name.
I hope the above code will help you...
Also i hope to tell the following for performance issues and also a good programming practice:
LOOP AT t_pi INTO w_pi.
MOVE-CORRESPONDING: w_pi TO W_FTAB.
READ TABLE t_hi INTO w_hi WITH KEY DOC_NAME = W_FTAB-DOC_NAME.
MOVE: w_hi-patient_name TO W_FTAB-PATIENT_NAME,
w_hi-place TO W_FTAB-PLACE.
APPEND W_FTAB TO T_FTAB.
ENDLOOP.
Please do a sy-subrc check after READ statement always...
LOOP AT t_pi INTO w_pi.
MOVE-CORRESPONDING: w_pi TO W_FTAB.
READ TABLE t_hi INTO w_hi WITH KEY DOC_NAME = W_FTAB-DOC_NAME.
If sy-subrc = 0.
MOVE: w_hi-patient_name TO W_FTAB-PATIENT_NAME,
w_hi-place TO W_FTAB-PLACE.
clear w_hi.
Endif.APPEND W_FTAB TO T_FTAB.
ENDLOOP.
Please revert back for clarifications.

Table Maintenance: Manual Transport for Entries in Customizing Table

Dear forum,
i'm facing a tricky problem at the moment. My customer wants the maintain a customizing table, but he does not want to transport the entries automatically (don't ask me for the reason), but manually.
The online help tells me, that this can be done.
In the SE11 i chose untilities -> table maintenance generator and for the subscreen "dialog data transport details" i chose "no or user, recording routine".
Continuing wiht the SE11 i chose untilities -> table maintenance generator -> environment -> maintenance objects -> transport "manual transport".
In the SE54 i created the events 10, 11 and 12 with the recommended coding from the online help.
But when i start the Maintenance via SM30 the points in the menue table view -> transport or edit -> transport are not active.
The function group does not include any generated statuses to activate the menue-points. What is missing toi get the popup, that asks me for the transport number?
Can somebody help me out or tried this before?
With kindly Regards,
Robert

wrong!
the online documentation says:
Manual transport
The object maintenance transaction offers a manual link to transports. You can branch to it by selecting the Transport menu option. In the transport session, you can then select objects to place them in a Change request. A special transport program may be available instead of the menu option Transport, to place the object in a change request. The setting Manual transport means that changes to the object are not automatically recorded. If the maintenance transaction offers an automatic transport link, in addition to the manual one, you should select the setting Automatic transport.
What has to be done to realise it except creating the events?

Entries in custom table

Hi,
I have created a custom table zmm which has the fields matnr, werks and art.
Is it possible to populate these fields from qmat table. Can I link this table to pick up the entries from qmat. The tables dont have a similar structure.
thanks and regards,
bindazme

Hi
You can't link your table with QMAT
write a program and fetch the values from QMAT into an internal table and modify your ZMM table with that internal table values.
You can't make this as related table QMAT

Data Entry into customized table

Hi All,
I have created a z-table and selection screen with four fields. Whenever I enter the data into these four fields, the data should go to the z-table through my report.
Will you please send me how to do this?
Thanks in Advance,
Ramana

Hi KCR,
You can do this by program or by generating a table maintanence generator using SM30.
IF you want to do this through program declare internal table with the same structure as that of your table and populate it with details as per the selection screen data and use "INSERT INTO <table name> FROM TABLE ITAB".
OR
Goto se11 give your table name change, in the attributes tab select display and maintanence allowed and then select menu path UTILITIES > Table maintanence generator . IN the next screen displayed
give Authorization groups as &NC& (if you dont want any auth check) Function group as your table name( you can give any name starting with Z), select maintanence type one step and give single screen as 100 ( you can give any number you want) and then select create button(located left top corner). this will generate a table maintanence for you.
After doing above steps go to sm30 and give your table name and select maintain which will display a nice table control with the table fields where you can maintain as many records as you want and click on save.
Thats it.
Reward if helpful.

Kalyan.
