Hello Experts,

Thanks in advance..
Best Regards,
Hardik B

Hi Hardik,
Please try writing your code in method POST of BAdI ME_PROCESS_PO_CUST.
If you want to search for a BAdI for a particular T-code, Go to t-code SE24. Enter class name as cl_exithandler, put a break-point on method GET_INSTANCE of this class and come out of it. Enter the t-code for which you want to find a BAdI. Once the program stops in the debugger, you can find the BAdIs and user exits in the exit_name parameter of the method get_instance.

Dnyanesh.

How to validate an attribute in a table/EO using a DB Table

I have an attribute LocationId in DuplicateLocationEO(LocationId,LocationName)
And I need a validation on this so that user can enter a LocationId that exists in LOCATION_ID of HR.LOCATIONS table
How to validate an attribute in a table/EO using a DB Table?

Issue: Insert a value into an attribute if it is valid, Like it is available in another table.
Scenario: Insert a Location into a DuplicateLocationEO based on LocationEO.
Solution: Create a Entity Validator on LocationId of DuplicateLocationEO that is list based on query of LocationEO’s LocationId.
Note: if the validation is created at attribute level, then it leads to NPE or Undesirable results.
Procedure Steps:
Step#01: Open desired Entity Object “DuplicateLocationEO”, Go to “Overview” tab & “Business Rules” finger tab.
Step#02: Select “Entity Validators” & Click “+”
Step#03: Set the following Rule Definition Tab:
•     Select Rule Type as “List”
•     Attribute “LocationId”
•     Operator “In”
•     List Type “Query Result”
•     Enter SQL Statement “Select LOCATION_ID FROM LOCATIONS”
Step#04: Now go to “Failure Handling” tab & Select radio button for “Error”.
Step#05: Click the Magnifier link to create a message.
Step#06: In the “Select Text Resource” popup. Provide the following
•     Display Value: “Invalid LocationId: {LocationId}. Please enter a valid Location”
•     Key: INVALID_LOC
•     Description: message when user enters an invalid location.
Step#07: Click “Save and Select” Button
Step#08: Click “OK” Button
Reference:
DuplicateLocationEO DDL Script:
CREATE TABLE "HR"."TEST_LOC"

Data source enhancement using BADI

Hi,
We had a 2LIS_* extractor which is enhanced with ZZ fields.
I look for the sode in CMOD which i couldn't able to find any
My assumption is the data source is enhanced using BADI.....As i am not familiar with BADI's how can i create for my data source enhancement code in BADI
Thanks

Hi ,
Not sure on your question.
Is the Enhancement already done and you want to check whether it is done in BADI/CMOD.
Or
You want to populate the Data using BADI/CMOD.
In any case you can use CMOD or BADI to populate the data ,the recomendded is BADI which can be created in SE24..you can google for some Docs on its creation and steps to be followed.
And if tis CMOD you have to create a project and then write the code and for that also there are DOcs avaliable.

Can I exit from paintComponent? ...or... how can I check for invalid data?

I'm writing a calendar applet for a programming class and I've nearly completed it but I'm stuck at checking for valid data.
What seems to be happening is that paintComponent() is being called before actionPerformed.
In actionPerformed (when they click the button), it checks to make sure they entered a valid month (1 to 12). If the didn't it dispalys a message, but if they did it calls repaint().
But even if repaint() isn't called, Java still seems to call it before actionPerformed and I get exceptions.
So I tried checking inside of paintComponent() by using a simple if(...) return; but that doesn't seem to do anything... it just keeps going through with the method.
So -- Once the user presses my button I want to make sure the data is valid before repainting the screen. How can I do this?

I validate it in actionPerformed which is called by
the action listener... that is what you meant right?
The problem is that it seems paintComponent() is being
called before I can validate the data with
actionPerformed(). I need to stop paintComponent()
from always being calledMVC. (Model, View, Controller)
Initially the internal value of the data (the model) should be valid (or null with a check in the paintComponent method)
paintComponent (the view part) shows the state of the valid data.
You press the button.
actionPerformed is called (the controller).
It checks the value and, if valid, writes it to the data (model), then updates the view.
At no point will the view have to render invalid data, because the model is only updated after actionPerformed checks the value.
The pattern may be applied with different classes performing the three roles, or different methods in the same class (sometimes it's easier that way for simple cases).

Hi Viren,
Initially I have tried what you have said, but ERROR is coming as AS YOUR PREVIOUS DELTA IS INCORRECT, YOU CANNOT LOAD THIS DELTA. I am not getting any option of REPEAT DELTA.
"I have set to DELTA REPEAT in RSA7(ECC) , but after saving, it is again coming back to DELTA UPDATE."
As I am not getting REPEAT DELTA, to get that I tried saving the 0FI_GL_4 as DELTA REPEAT in RSA7 (ECC).
Please let me know any more information required.

How to create tables for control data

HI
How to create tables for controls of types of data (screen control)? what is the process for this
Regards,
Anil

Well, do you want to do it the easy way? If so, then just create a table maintenance program. You can do this via SE11, utilites, table maintenance generator. The table maintenance will be generated and you can then maintain the table via SM30.
If you want to go the more challenging way, you can write your own table maintenance program using a table control on your screen. You can use the table control wizard to help you along.

How to clear cache for XML data source?

Hi All,
I'm facing a problem loading XML data into Oracle using Oracle Data Integrator. The problem is ODI will cache the data of the XML file at the first time loading the data. And afterwards, when the XML file changed, ODI will load data from the cache.
I did serveral testing on this. If I run the interface in local agent of the designer, I must restart the designer to clear the cache. If I run the interface in an agent, I must restart the agent to clear the cache.
Below is my configuration:
ODI version: 10.1.3.5.0
The technology of the source: XML.
JDBC driver: com.sunopsis.jdbc.driver.xml.SnpsXmlDriver
Does anybody know how to clear the cache of the agent or XML?
Thanks.

Hi ,
Use drop_on_disc or dod in your JDBC URL .
example ,
jdbc:snps:xml?f=C:\mutation.xml&d=C:\mutation.xsd&lf=C:\mutation.log&ro=true&dod=yes
The dod (drop_on_disc) drop automatically the schema when closing the JDBC connection.
dod option must be the last option of the URL.
This option removes the reference to the schema from the driver, and if the schema is store in memory, it also drops the schema. If the schema is stored in an external database (set via db_props), the driver tries to drop the database schema.
Thanks,
Sutirtha

How to read char() for bit data DB2's type in Oracle?

Hello,
I am developing an application (from JDeveloper) to operate with two data base. In one hand threre is Oracle and in the other one DB2 (AS400).
I am trying to read a DB2'sfield with the "char() for bit data" type from Oracle, but I can't read it.
I have trying:
rset.getObject(1) -->[B@1a786c3
rset.getBinaryStream(1) --> java.io.ByteArrayInputStream@1a786c3
rset.getAsciiStream(1) --> java.io.ByteArrayInputStream@2bb514
rset.getCharacterStream(1) -->java.io.StringReader@1a786c3
Do you have any solution to see the value of this type of field?
Thank you and regards

I have to synchronize unidirectionally from the Oracle database to DB2. And I'd like to save the information of the record of DB2 prior to the update operation.
And here is where the problem arises for me, because when I try to read from Java with the connection established on DB2 is unable to interpret the information. While there are no problems from Oracle to consume the information, it happens that DB2 field types are not common with Oracle, such as char () for bit data. From what I could find the equivalent in Oracle would be raw (), but since Java is possible to read this type of information... And this is my doubt, it is necessary to do any type of cast or to do a special view to retrieve this information?
