How to handle transactional data?

Hello,
I try to do a customer analyse with ODM, for that
I collect from some different tables many of attributes,
some of them are transactional.
How I understand the ODM manual, I have to select for
the analyse that the data are in the transactional
format, but what I could do if there are not only 3
different columns, which define the transaction? Whit
other words I have more than one attribute which is
transactional.
Is the right Selection of the data format important for
the results, or could I use the single data format, if I
could not to do that, which alternative I have?
M. Neudeck

Hi,
What version of ODM are you using.
If you are using ODM 10.1, you have the option of either using the java api or the pl/sql api. Each api has a different approach for handling txn data.
The java api will accept only a single txn format table (case id, name, value). This table can contain a mixture of data that are not of the same metric. You could have quanities, counts, categoricals etc.
The plsql api has a custom object type for nested numericals or nested categoricals that you use to create a nested table as a column. You can create multiple columns as nested tables in your input table for model build.
As to data format, that issue is also api dependent. In java,you can specify the mining type in the mining function setting. In pl/sql, the mining type is based on the data type, so data type is very important.
Thanks, Mark

In BDC how you handled header data and item data

In BDC how you handled header data and item data

Raja,
Can you be more clear ?
Usually you load the header data one and then loop at the item data and then load the item data.
This example should help you.

How to load transaction data

Hi,
Can anyone share how to load transaction data from BI Cube to BPC Cube. How do i map key figures in BI to BPC in NW version. Pls share any document that explains.
Thanks
Veeru

For example, I've a BI Actual Cube with two key figures quantity and amount. I would like to copy this data to a BPC cube. Since BPC cube has only signed date (one key figure), how do we transform the data from BI cube to BPC. Can we able to achive this using transformation and conversion file in NW. Is SAP providing standard packages that convert KF's in BI cube to BPC dimension members.
Whats the approach you are doing for the scenarios where you are converting multiple key figures into BPC dimensions. I did not find a good document that explains this process.
Thanks for sharing any information.

Hi,
it works in the same way as before in case you are not using the new features like the dtp and the transformations. Using the new features, you schedule a infopackage to load the data up to psa and schedule a dtp to post the data to the targets.

How to handle transaction control--- in the dbms query or in JDBC? or BOTH?

Hi all,
we have a servlet application which do insert, update to a few sybase tables. so far we don't have any transaction management control in either store procedure or in JDBC call. i like to know where should we enforce this control logic? in both place or either one is enough?
thanks!!

according to your answer, is it safe to say that we
should NOT
handle transaction control in both query and JDBC
call? i am on the side of JDBC
program control. However our manager feels that if we
handle it in two place, we could be more error-proof.
i don't know how to convince him that only one place
could make it work. Double your rollbacks double your fun! Odd that a manager is getting involved at this level...
Providing transaction control at both places, as a rule makes absolutely no sense at all (to me). I actually believe that this would be far more error-prone (not error-proof). It's really a logistics issue. When you are working on the Java code, you won't have the stored procedure(s) code right there. While you may design it masterfully at first, as maintenance occurs, the mastery can easily be lost as assumptions are made on when and where commit or rollback processing is going to take place. The end result would be a system that could easily corrupt the logical integrity of the database.
If you have to make a decision up front, and you believe performance will ultimately be a concern, then your decision should be to handle transaction management within the stored procedure(s). However, this decision will make the stored procedures far more complex than what the DBA or application staff is familiar with. You would also have to take some care to release resources as appropriate within the Java code.
If you decide to manage transactions within JDBC, it is possible that you will have to move a portion of transaction managment to one or two of the stored procedures. This would be a 'fix' for a poorly performing functionality, and you would simply take care to limit this as much as possible.
I wish I could guide you specifically, but I'm working at 20,000 feet related to your specific application needs.

How to handle empty Dats field received from SAP RFC response

Hi All,
I am invoking a SAP RFC which gives me a Dats field in response.
A valid dats fields is successfully received by my pipelines.
But when an empty Dats field is received, My pipeline fails and i get error.
How to handle the empty Dats field from SAP

Hi Anant,
This is because the legacy SAP adapter accepted RFC messages with date field empty. In the new version, the same call results in an error. WCF-SAP adapter doesn't allow blank XML nodes.
You need to use the below custom pipeline component as a workaround.
Refer:
Pipeline component for enabling legacy behavior in WCF-SAP adapter.

How to handle The Date error???

Actually I am using three dropdown list as day,month and year
day contains 31 items and same values i.e., 1,2,3...31
and month contains jan,feb,....dec
year 1981,1982,.....2007
and I am concateded these three to form date as
d:=:day||'-'||:month||'-'||:year;
Now my problem is
when i am selecting values 31 jun 1980,30 feb 1980 i.e., non existing dates then it is throwing
"Unhandled trigger ..... "
please tell me how to handle it?

There are a number of different exceptions you can get with dates.
SELECT To_Date('10132007','DDMMYYYY') FROM dual;
ORA-01843: not a valid month
SELECT To_Date('99122007','DDMMYYYY') FROM dual;
ORA-01847: day of month must be between 1 and last day of month
SELECT To_Date('10-FEB-2007','DDMMYYYY') FROM dual;
ORA-01858: a non-numeric character was found where a numeric was expectedFor this I would just trap the ORA-01847 and 'when others' exceptions.
