Have field map to existing record in table by secondary key

Let's say I have a person table and a code table.
person.datastoreId
person.name
person.foreignKeyToCodeValue
code.datastoreId
code.codeValue
code is a static lookup table. I want to persist a new Person object:
personObject.name = whatever
personObject.code = something
Obviously, person.code is mapped in the mapping XML to the code.codeValue
table.
If I call makePersistent(personObject) it will create a new record in the
code table, right? if codeValue had a unique constraint on it, is there a
way, so that it would automatically associate that person.codeValue with
the existing record instead of creating a new one?
I know I could do a query to get the codeValue object first and assign
personObject.code to that, but I'm wondering if there is a way to avoid
that.
Thanks!

Joel-
You will need to implement this sort of singleton pattern yourself.
The most common way would be to do something like:
public class Person
private Code code;
public void setCodeValue (String value)
try
code = (Code)JDOHelper.getPersistenceManager (this).
getObjectById (new CodeValue.ID (value), false);
catch (ObjectNotFoundException none)
// none exists; make a new one with the specified key
code = new Code ();
code.setPrimaryKeyField (value);

BDC for existing record in table control

Hi,
I have a requirement to change existing records in table control through BDC. Is there any way I can choose the respective record from Table Control through BDC dynamically.

Akash

/J4I/015PER, this transaction is used for adding permits to Operation in WEC. It has list of operations in Table Control. Permit can be added for choosing the operation from table control.
Our custom program is designed to add permits for the operation. So if I have to use the above transaction for adding permits, then first I have to choose the correct operation from the table control and then add permit.

Error in ALV : Field Does not exists in Output table .

Hi All,
In my ALV report, program get dumped and showing error when i tried to put a col named Distribution channel ion the alv.
I have put the Distribution cannel field in the IT_FInal table , but still getting folwong errors :
Error : Field Symbol is not been assigned.
As Instructed i have passed I_INTERFACE_CHECK = 'X'.
By this i am getting detail error that :
Field Distribution channel does not exists in Output table & Heading for List is missing .
But i have maintained the distribition channel in IT_Final table
Please suggest wheather we have to define dis channel in any other place.
Thanks in advance.
Can any one help me regrarding this.
Thanks in advance.

Hello,
You have to populate the same in the fieldcatalog as well, i think you have not maintained this field there.

Field does not exists Error - INSTALLATION TABLE

We have applied ML MP9 on system database for our eRecruit Instance. We are getting a "Field does not exists" (for eg., INSTALLATION.GL) error for the components which refers to INSTALLATION table.
The error gets resolved if we introduce a .value in PeopleCode.
Note: Our Dev Instance is working fine which has ML MP9 applied on it.
Please find the PeopleBooks Comments for the .value Property:
Considerations Using INSTALLATION or OPTIONS Tables
When using the INSTALLATION or OPTIONS table, you cannot use the Value property. You must use the old style format, not the field object format. For example, the following code is invalid:
If %Page = Page.GP_RUN_TYPE And
INSTALLATION.TL.Value = "N" Then
&RS2.HideAllRows();

HOW DO I ADD A FIELD TO "ALL" EXISTING RECORDS IN ADD BOOK

Just trying to find an easy way to add a field to all my records...a text field....
Any thoughts or input would be appreciated.
THKS
C.R.

Hi P,
Assuming that this, being asked in the AppleWorks community, is a question regarding an AppleWorks database document, the answer is, "Quite easily."
Open the file, go Layout > Layout and choose the layout on which you wish the field to be placed.*
Go Layout > Define fields (or press shift-command-D to get to the same place)
Type the name of the new field into the Field Name box.
Choose the type of field (Text) from the pop-up menu to the right of the box.
Click Create.
The new field will be added to the Field list in the dialogue.
Repeat for each new field you want to add. When finished, click Done.
The new field(s) will be added to all existing records, and will be placed on the active layout. You can add it/them to other layouts using Layout > Insert fields.

Barry

person.getXrefs().add(xref);
person.getXrefs().add(xref);
pm.currentTransaction().begin();

Exception in thread "main"

First off, use the '-primaryKeyOnJoin true' flag when running the reverse
mapping tool so that you can get rid of that useless Xref class and have
a direct relation between Person and Project. See the documentation on
reverse mapping tool options here:
http://www.solarmetric.com/Software/Documentation/latest/docs/ref_guide_pc_reverse.html
But your real problem is that you are creating new objects, assigning
primary key values, and expecting them to represent existing objects.
That's not the way JDO works. If you want to set relations to existing
objects in JDO, you use the PM to look up those objects. If you try to
create new objects, JDO will assume you want to insert new records into
the DB, and you'll get PK conflicts like you see here.
There are several good books out on JDO; if you're just starting out with
it, they might save you a lot of time and help you master JDO quickly.

Inserting existing records to table and getting new identity ID for each row

I have an issue that I inherited where I need to insert some data to 12 tables related by FK for about 40 records to an existing database through TSQL, SSIS is not an option..
Essentially the situation is that many weeks ago someone deleted a bunch of data and I cant do a restore of the database as new data has been entered so I need to "reconstruct" the data and reinsert it back. I cant just reinsert the data with the
same Primary keys as they are autogenerated. I restored a backup of the database taken prior to the deletion and have got all of my data I need loaded to temp tables. Now the issue I am running across is how to insert my "Main" table data row by
row and get the new identity and then update the corresponding row to the source temp table so that it can be used for the next 11 tables that need that Foreign Key.

How do I loop through the 40 records I am attempting to insert into the "Parent" table though?
You don't. That is, you don't loop.
You do:
MERGE target t
USING source s ON 1 = 0
WHEN NOT MATCH BY TARGET THEN
   INSERT (col1, col2, ...)
VALUES(col1, col2, ...)
OUTPUT (t.JobId, s.JobId) INTO @idmap(newid, oldid)
UPDATE source
SET newjobdid = i.newid
FROM   source s
JOIN   @idmap i ON s.jobid = i.jobid

Problem in modifying the existing record in table control

Hi Experts,

Add a new field to an existing Condition table

How can I add a new field to an existing condition table?
I have table 971 and I want to add INCOTERMS (INCO1) to this existing table but do not see how to add it.
Thanks

Hi Vicky,
I dont think you can add new fields to the condition table once you have activated the condition table.
SAP says you can only make limited changes to the condition table, like changing the description, fast entry screen, header and footer fields, but not able to add new fields to the table, and I think that is the correct approch or else for the same table you will have two sets of condition records.
Please refer to the below link:
http://help.sap.com/saphelp_erp60_sp/helpdata/en/de/7a8534c960a134e10000009b38f83b/frameset.htm
What you can do is create a new condition table with additional field and assign this table before the currently used table in the access sequence.
Hope this helps.
Regards
Raj

How to know the R/3 table field mapped to BW info object!

Hi,
I have an extractor which is extracting the data from R/3 using View in generic data source.
Now i am making a documentaion of each infoobject involved in the extraction of how exactly it is mapped and how is it getting filled.
In transfer rules i could find the R/3 find easily but i want a table as well as i need to make a screen shots as well for the documentaion.
Example, the field AUFNR which is order number is existing in three tables namely AFRU,AUFK and AFKO ( all are used in view definition )
Now how can i ensure that from whcih table the data is getting filled to the BW info object?
Any suggestions would be appreciated .
Thanks,
Ravi

OC4j10.1.2CMP bean not updating field after creating a record in the table.

I have a simple table in Oracle 9i database:
SQL> desc temp_tbl
Name Null? Type
OPER_ID NOT NULL NUMBER(5)
OPER_STS_TM_DT NOT NULL DATE
OPER_STS_CD NUMBER(2)
First 2 fields are the Primary Key. last field is standalone. No FK references.
I generate a CMP bean using Jdeveloper 10.1.2 for this table.
Then I try to insert a record into this table and update the oper_sts_cd field.
Problem: CMP inserts the record correctly, but does not update the field: oper_sts_cd, even though trace indicates that the field has been updated.

How to add one more field to an exist internal table

hi abapers
i am a very new abap programmer and just started learning it.
i want to know How to add one more field to an exist internal table.
lemme me put my question in a very simple way.
i have a internal table having fields f1,f2,f3 and which also that internal also contains some data.
now i want to add two more fields (mm & nn) to that internal table now.
how can i do that.
and i wanna know the websites names where i can find some brain teasing questions in abap programming.
eagerly waiting for ur reply
regards,
Maqsood A Khan

Hi, MAQSOOD.
You can insert more fields in your internal table like this.
refer this code snippet.
DATA : BEGIN OF tbl_itab OCCURS 0.
        INCLUDE STRUCTURE zsdtc009.
DATA : vkorg   LIKE vbak-vkorg, "inserted one
        vtweg   LIKE vbak-vtweg, "inserted one
        vkbur   LIKE vbak-vkbur, "inserted one
        vkgrp   LIKE vbak-vkgrp, "inserted one
       END OF tbl_itab.
you can also read the book "Teach yourself abap in 21 days"
at http://cma.zdnet.com/book/abap/
but that book is just about basic concept of abap and report program.
it doesn't give a lecture for on-line program.
you can get pdf version books(about abap, sap...things) from sap.
http://help.sap.com/printdocu/core/Print46c/en/Data/htm/english.htm
I wish I could help you.

Adding new field in an existing condition table

Dear friends,
I have an existing condition table for material exclusion with the combination of Plant and material.
Is it possible to change this table and add a field of division also?
Regards,
Ronnie

Hi,
The optimzed solution is to better create a new sequence of fields including the division, so that a new condition table is created based on the key combination or access sequence.
You can add a new field to an existing condition table using APPEND structure facility in Se11. But once on activating the table, how will this division field get populated in the table.
But whereas if you create a new key combination, the data for this condition tables will automatically gets filled up while creating master data thro VK11.
So, its better to go for a new access sequence combination
as a new table is created for this key combinations.

JLN

Specify field mapping when changing table location

I want to change the tables in a report to refer to database tables with a different schema, and specify the mapping of fields in code.
I already have code that changes table locations successfully when the schema does not differ, using the RAS API. As far as I can tell, the RAS API doesn't have a way of handling schema differences. Is that true?
OTOH, the higher-level CR API does appear to have a mechanism to do field mapping, using the FieldMapping event in the ReportDocument class. I've been trying to use this API for the job, but I don't seem to be able to change the location of a table in the report.
Here's an example scenario:
The report was created using an ODBC data source Source1 that contains a table Table1
I have an ODBC data source Source2 that contains Table1 as well as a table Table2 that is identical to Table1 except that the field names are all slightly different
I want to change the report so that it uses Table2 in Source2
I've managed to get the report switched to Source2 with code like this:
report.DataSourceConnections[0].SetConnection("Source2", "", id, pwd);
Here's the code I'm using to try to change the report table to refer to Table2:
            Table table = report.Database.Tables[0]; // only one table in the report
            TableLogOnInfo logOnInfo = table.LogOnInfo;
            logOnInfo.TableName = "Table2";
            table.ApplyLogOnInfo(logOnInfo);
            report.VerifyDatabase();
I've also tried the simpler
table.Location = "Table2";
Neither approach changes the table location. I know this because when I preview the report I see data. Since the field names are all different, changing the location should have removed all the fields from the report. (Also, the event handler I have hooked up to the FieldMapping event is not called. Yes, I did enable the event in the ReportDocument.)
So:
How do you change the location of a table using the high-level API?
If you change the location using the RAS API, is the FieldMapping event fired? (Haven't tried this, but somehow I doubt it.)
Is there a way to do field mapping with the RAS API?
Thanks!

Hi Rick
This is not considered a bug. It is a limitation that has been discusses extensively in many of our internal meetings. The implementation job proved to be much too massive and with highly limited ROI. E.g.; the number of requests for the feature is just not there...
