Key in table

Is it advicable to make all the fields in a table as key? The case is to maintain a control table where 2 fields are required and it should be unique also. is there any thing wrong in doing it?

hi Rob,
I wanted to record whether a particular transaction has occured or not. If ocuured on the same date it should not be allowed once again. So the transaction and date are my only fields and only keys. Is there any SAP tables with all the fields as key.

MDM API to read the Record Key Mapping table

Hi,
Does anybody know what class/method I can use to read the Record Key Mapping table?
For the Business Partner table the Key Mapping table has this columns:
Default / MDM Partner ID / Remote System / Key
I have everything but the Key. How can I read it?
Thanks in advance,
Diego.

GetKey Mapping is one of the available Web Services as of SP4.
Else you could use the Java API to get the Key Mapping.
CatalogData class has the following method
GetKeyMapping
public java.lang.String[][] GetKeyMapping(java.lang.String agency,
 java.lang.String table,
 int[] recordIDs,
 boolean isDefaultKeyOnly)
 throws StringExceptionRetrieves the key mapping for each record.
Parameters:
agency - the agency name.
table - the table name.
recordIDs - the list of records.
isDefaultKeyOnly - True to retrieve only the default value, False to all key values.
Returns: the key values for each record.

Error on activating the table "DB length of the key of table too large"

Hi Experts,
I am getting the error while activating my table PSM_REQ_BO_ELM_NAME. Activation error log is as follows
"DB length of the key of table PSM_REQ_BO_ELM_NAME is too large (>900)"..
I have a table which has 4 filed as key one with char 6 and rest 3 with char 120 each.
Could you please help me to get rid of this error.
Thanks in advance.
Regards,
Pradeep

When ever we create a table in Data dictionary, a corresponding database table will be created in Data base server. For the primary key we maintained in Data Dictionary, another data base table will be created seperately where as the table length should not exceed some limit set by the Administrator.
So, Reduce the length of the primary key in the table by deleting the field as key field/ reducing the size of the field.
In your case, maintain the primary key field length not more than 400.
***Length if the Primary key should not exceed 120. other wise performance will be low while fetching the data.

ORA-02266: unique/primary keys in table referenced by enabled foreign keys

Hi,
I am trying to delete data from a table by dropping a partition. I have identified all the child tables by running the following command.
select 'select count(*) from '||table_name||' where employee_id = 100;'
from dba_constraints
where constraint_type='R'
and r_constraint_name in
(select constraint_name from dba_constraints
where constraint_type in ('P','U') and table_name='EMPLOYEE);
'SELECTCOUNT(*)FROM'||TABLE_NAME||'WHEREEMPLOYEE_ID_ID=100;'
select count(*) from PT_ORDERS where employee_id = 100;
select count(*) from PT_DEP where employee_id = 100;
select count(*) from PT_SKILLSET where employee_id = 100;
I dropped the partition for employee_id 100 in all of the child tables. The select count(*) returns 0 rows for each of the above.
When I try to run the below command on the EMPLOYEE table, I get 'ORA-02266: unique/primary keys in table referenced by enabled foreign keys'.
alter table EMPLOYEE drop partition EMP_ID_100;
I cant see why I am unable to drop this partition now as there is now child data in any of the referenced tables. Any suggestions or help on this would be greatly appreciated.
Thanks.

Rob

You should disable foreign key constraints first and drop partition. Deletion of rows or dropping partitions in childs don't work in this case
as you have the global dependency:

I guess you should consider such option as Referencial partitioning (with some restrictions).

Add a primary key to table.

Hello everybody,
I want to add a primary key to a table but it doesn't work.
select count(*), count(id) from tableA;
COUNT(*) COUNT(ID)
830447 830447
You see: The number of ids is equal to the number of rows. The ID is not marked as unique but it should be unique. I try to set id as the primary key:
alter table tableA add constraint "pk_constraint" PRIMARY KEY (id);
But I a get an error message: ORA-02437: cannot validate (pk_constraint) - primary key violated.
What is the problem?
I use Oracle 11g.

Hi,
The "fa_additions" is a view, not a table.
You should update the base table "fa_additions_b".

Populate choice component with 2 primary key in table

There are 2 primary key in table. When I create my uix with jheadstart, the UIXs don't populate choice component. How can I create automatically populate choice component, with 2 PK in table?

A choice component can only have one value attribute. So if you have a composite primary key in the table you use to populate the choice, it will not work correctly, because based on this single attribute the choice cannot render the correct row as selected.

Issues while changing primary key in table

Hi
I have one table. In that two fields are primary key. I want to change the second PK as FK only. But when i am changing this field as FK. Its showing one error 'Primary Key Change not permitted for value Table ZCAUSECATMASTER' . How to avoid this error.
Please help me.

Hi.....
Remove that primary key for the second field and assign your foregin key..table to that filed.....
So when you give entries in that second filed it will be validated with its foregin key table......its nothing but check table...
what all values in the foregin table only can given.....

Hi,
As the error message sugggested, INSERT directly into the sales table. You can get the values from a sub-query that joins whatever tables are needed, including sales itself. MERGE might be simpler and more efficient than INSERT.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
If you're asking about a DML statement, such as INSERT, the sample data will be the contents of the table(s) before the DML, and the results will be state of the changed table(s) when everything is finished.
Explain, using specific examples, how you get those results from that data.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0).

Did elationship fields in entity bean with CMP same as foreign key in table

did elationship fields in entity bean with CMP same as foreign key in table database.so we don't have to make some foreign key column in table database.
did Container handle that both.
I need some answer
thank's

Suppose you have Group and user entity. Relation is 1-m. One group many users. When you create user, you dont need to send group id, All you need is create user and add it in collection (cmr-field) in group(user belongs to). Container will add its group id in user entity as well as in db.

Posting rules defined in account key in table T007B

Hello Expert,
I am trying to post a document in FB60, however SAP generates below message
'No posting rules have been defined for the account key in the tax table in table T007B.
Change the tax table, enter an account key already defined for the transaction in question or define the posting rules for a new account key in table T007B'
I have checked the Rules, Posting keys and Accounts for that Account key in transaction OB40, however the error continues to exist.

Thanks in Advance...

Looks like you have a view that contains the ROWID of another table. Does the view work first from sqlplus? See whether it returns any data. Its a ORA- specific error. So, the error is related to your view rather than BI EE. Also, how many columns are you trying to pull in your report?

I don't have intimate knowledge of SQL Server, but to me, your code seems reasonable. I guess there is some "fine point" (a bug?) to using self referenceing foreign keys in SQL Server. It doesn't seem plausible that the error originates with the driver, unless it's a very intelligent kind of driver.
A "Gordian Knot" kind of solution to your problem is to ask whether you really need the foreign key constraint in the db schema. Is the table used by something other than your EJB? Anyway, putting logic responsible for the correct functioning of your EJB into the db schema is often a bad practice, as it makes the code harder to understand, maintain, port etc.

Records are getting duplicated on presing enter key in table control

Hi All,
I am using table control in module pool program. The issue is records are getting duplicated on press of enter key.
I cannot use sy-ucomm enter and do some validation thing in my code. As the record should get update in int_tab(internal table). Otherwise ZSTR_TAB(table control)will be blank after pressing enter key.
I have gone through all the previous threads on this. Have implemented sol provided in one of threads. Now records are not getting duplicated but the next line is getting disabled. The code to avoid duplication is :
MODULE read_table_control INPUT.
data tc-lines type i.
DESCRIBE TABLE int_tab LINES tc-lines.
IF tc-lines GE control-current_line.
    MODIFY int_tab FROM zstr_tab INDEX control-current_line.
ELSE.
    IF gcreate_code = 'CREATE'.
      zstr_tab-zemp_num = gemp_num.
      INSERT zstr_tab INTO int_tab INDEX control-current_line.
    ENDIF.
    IF gchange_code = 'CHANGE'.
      MODIFY int_tab FROM zstr_tab INDEX control-current_line.
    ENDIF.
ENDIF.
ENDMODULE.
This module is in PAI. Now how to make the lines in control input enabled??
Any other sol for avoiding duplicate records on pressing enter key?
Thanks,
Seema

Hi,
Have you written any code in when Others of case...Endcase ?
If Yes then checkout if there is anything wrong over there, debug and check.
If not then write delete adgecent duplicates from Int_tab comparing key fields.
Also check in PBO, if you have written any query that selects data from particular table and appending the internal table irrespective of entry is already exist. So you should write select query in the if...Endif block as below,
If int_tab[] is not initial.
select * from ZSTR_TAB
into table int_tab
where .........
endif.
If above is not the case then debug and check where exactly entries are getting duplicated so that I can have idea what exactly is happening.

Pressing tab key within table not scrolling to next input field

Hi All,
I have a table with editable and read only fields. I have more than 20 columns. When the tab Key is pressed it scrolls only to the editable fields that are in the visible screen. It does not scroll the table to the right to the next input field.
However if I change the screen size so that the scroll bar is required for the browser then it will scroll across moving the browser scroll bar, moving the cursor to the input field that was not visible. Again it does not go further moving the scroll bar within the table to the next editable field to the right.
The table has been set to scrollable with the scrollable column count set to 8.
We are using explorer 8 on 7.01
Is it possible to have the tab key move from input field to input field scrolling the table to the next input field if it is not visible yet?
Thanks
Bruce

What you describe sounds like the correct functionality. If you set a scrollable column count, only the visble rows are actually rendered on the client side. When you use the horizontal scroll bar, you are triggering a server side event to retrive the next set of visible columns. Therefore the browser doesn't actually know anything about non-visible columns and hence the tab can't go to them.
When you increase the number of visible columns (or don't set anything for visible column) you render al the columns on the client side and use the browser scrolling. Therefore the tab works.
