Additional field in join table for CMP EJB

Hello,
I'm trying to perform this task using CMP entity beans:
The entity A has a CMR relation of cardinality m-n with entity B (bidirectional) (This is working fine).
I want to add a parameter to the relation.
Ex : When I find that A1 is linked to B1, I need to perform "x" times an action. x would be my parameter, and I would have kept this parameter as an additional column in the join table A_TO_B.
Could anyone provide an example of how to perform this with CMP EJB?
NOTE: I'm using OC4J 10g 9.0.4 standalone (and cannot change my version).
Thanks

Manohar,
You need to create an append structure for table VBAP (for example ZAVBAP) using SE11. In this structure you create your ZZ fields. If you need a non-SAP domain/data element for your field then you need to create it first using the same transaction and activate it. Attach ZAVBAP to VBAP so the SE11 shows:
.APPEND in the Fields column and
ZAVBAP in the Field type column.
Your ZZ fields will be shown automatically.
When you have finished then activate your ZAVBAP structure. You will notice when you go VA01 (for example) that a lot of programs are being recompiled. Don't worry. It will be ok.
The user-exit screen number for items is 8459 (in program SAPMV45A).

CMP additional field in join table

I'm sorry if this question was already post on the forum, but I could not find any answer....
I have an existing application which is using CMP entity beans.
A and B have a many to many relation, then the relation is mapped to a join table with 2 columns (key of A, key of B)
I need to modify this relation in order to specify the number of B linked to A for a given relation, then adding a column to the join table :
(key of A, key of B, MyParameter)
Is there a way to specify the parameter in the beans ?
Do I have to change my CMP entity bean to BMP beans?
If I do have to use BMP, many other CMP entity beans have relations with one of the beans that I will have to modify to BMP. Will I have to transform all the CMP beans with relation to BMP beans (then almost all the application) to BMP?
Thanks a lot for your answers.

Problem with joining tables in cmp bean

This is for an informix database. when i specify to join tables in CMP beans i get a sql error.. this is what the SQL join statement looks like when the server spits it out:
SELECT t0.id, t0.name, t0.available, t0.available_date FROM drs_product t0, outer drs_category t1 ON t0.style=t1.style WHERE t0.available = 'T'
it puts the "ON" string into the join?? this gives me a SQL error, it's supposed to be like this:
SELECT t0.id, t0.name, t0.available, t0.available_date FROM drs_product t0, outer join drs_category t1 WHERE t0.style=t1.style AND t0.available = 'T'
how can i fix this

nevermind..i figured it out again.. in the INFORMIX DYNAMIC SERVER.properties file replace the left join attribute with this:
LEFT_JOIN= left join
make sure there is a space before the "l" in left and a space after the "n" in join, otherwise it will be a sql error:
the previously LEFT_JOIN=, outer statement is clearly wrong for this database.

Hi Girish,
People are answering not for points, just to share the knowledge.
And I think the way of structure is wrong. i think we cannot pass two single values in your way. am not sure about .
low means it will accept single value. for one record in sign structure.
wait for other replys.

How to map primary table for CMP?

I am using the SunONE studio EE and trying to deploy a CMP Entity bean and get the following error:
Validation failed for board.ejb.user.UserBean. Verify that all fields are mapped.
CMP Mapping Error in bean User:: Warning: The bean pcImpl0.moduleComp0.board.ejb.user.User is not mapped.
Set the primary table for the bean.
I have the CMP resou4rce set to the JNDI name of my database connection but I can't figure out hpw to set the primary table for the bean. Any help would be apprecieated.

You will need to do the mapping via the UI available on the bean (in the context of the module).
If you expand the ejb-module, you can select a bean that is in that module.
There are two SunONE App Server specific tabs added to the property sheet for a vselected CMP bean.
Entering data for these properties will do the mapping and resolve the error you are encountering.
Note: The current implementation does not conjure up tables for the entity beans (unlike the RI).

Weblogic Deployment Descriptor for CMP EJB

Hi all,
Am new to EJB, CMP. Pls help me how to write deployment descriptors for the CMP EJB for Weblogic.
Give me the list of the Deployment descriptors needed and also pls give me some samples
thanks in advance
rgds
Ravi Bharathi

The easiest way is to go through some tutorial or refer the code samples. If you have installed weblogic, there are examples provided in the weblogic installation folder itself for each type of bean. Basically for cmp you have to provide the table names and mapping between the class variables to db fields in weblogic_cmp_rdbms.xml deployment descriptor.

+1 for this. it's taking a while to lad on my 2 year old ipad mini, so this would probably help. though in my case, it's going to be an iOS install that needs to ho on a diet.i haven't worked out if it's the player part of the spp that's swelling or additional social aspects of the app that sre growing in size unecessarily.all things said, a music player shouldn't really need to be 75mb+.the android install on my htc m8s is about 13mb, by comparision, less than 2 thirds of the install size.

What is the better way to join table for ASE 12.5?

To join table with T-SQL, there are 2 options:
select * from tab1 a join tab2 b on a.id = b.id where x=y
select * from tab1a, tab2 b where a.id = b.id and x=y
this is only a syntax difference or there is a performance difference? which one is better for performance?

The first query (using the join clause) is the ANSI standard way of writing joins and is usually supported by all mainstream RDBMSs.
The second query is the T-SQL method of writing joins and may have limited re-usability with other RDBMSs.
In most cases which one you use is usually one of preference, ie, which ever one you're comfortable with.
From a technical perspective there are some join constructs that you cannot build with T-SQL joins, but can build with ANSI joins (eg, you may have problems in T-SQL with a table that you want to be both a) an inner table of an outer join and b) part of a equi/inner join).
Soooo, ANSI joins provide you a lot more flexibility in coding as well as portability (between other RDBMSs). But if you're going to work with ASE you'll still need to understand how T-SQL joins work as you'll see quite a lot of T-SQL join-based queries.

How to populate the logical_group field in V_LTDX (table for layouts)?

Hi,
Scenario:
I have implemented the ALV using CL_SALV_TABLE. In the grid we have a 'Choose Layout' button where we have the options of choose, change, manage etc. the layouts. If we create a layout, the layout is saved in the table LTDX(view: V_LTDX).
Issue:
How do we populate the 'Logical_group' field in the table while creating/changing the layouts?
Please suggest..
Regards
s@k

Solved..:)
Solution:
While creating the ALV grid, use the method 'get_layout' of the class CL_SALV_TABLE and get the reference of the layout in a reference variable.
Data:
gw_key TYPE salv_s_layout_key.
gr_layout = gr_grid->get_layout( ).
gw_key-report = sy-cprog.
gw_key-logical_group = gc_log_grp." Pass the logical group here say logical group: 0001, 0002, etc. for each ALV
So, whenever you create/ change a layout on the ALV grid, the system automatically passes this logical group and saves it in the table LTDX.

SAP GRC 10.1 AMF No data selected when adding duplicate fields from separate tables for configurable data sources

Hi There,
In SAP GRC 10.0, our team had an issue where we could not add duplicate fields from separate table (see ERROR: Select Currency/UoM field for the selected analyzed fields). This was resolved by the SAP Note 1904313/ 1904314 (http://service.sap.com/sap/support/notes/1904313).
We upgraded our system to SAP GRC 10.1 SP05 and could now add the duplicate fields from separate tables. SAP Note 1904313/ 1904314 was part of SAP GRC 10.1 SP03 so it makes sense that we, in a higher version (SP05), would be able to do this.
The issue now is when we add the duplicate fields from different tables and run the Ad-hoc Query to test if the data source works correctly, the No Data Selected warning persists. This means that the data source provides no data for analysis, which is required to write our business rules.
Below is an example:
Basic data source with just one currency reference field EBAN-WAERS.
When you run the Ad-Hoc Query you receive data.
Basic data source with second currency reference field EKKO-WAERS.
When you run the Ad-Hoc Query no data is found.
Please also make reference to the following thread logged by my colleague (ERROR: Select Currency/UoM field for the selected analyzed fields)
Any assistance to receive data with duplicate fields from separate tables will be highly appreciated.
Thanking you in advance.

Gary Khan

Auto-numbering of item field in custom table for EEW enhancements for BUPA

Hi Experts,
We have a requirement to generat 3 custom tables in EEWB,for BUPA and assigned it to BP_HEAD. I have done all the generations and it works fine, the problem is that the tables that are generated is not allowing us to have a data(material) of 0...n cardinality.
The table that we are aiming is to allow multiple records, so my solution is to have an extra item number field so that it will allow multiple records for a material. But users are requesting to have the item number field of the tables to be auto-numbering.
I would like to know if this autonumbering is possible or not? what methods in BP_EEW should i use to implement this logic. I 'm very new to CRM2007, so I'm still not very familiar on how to use the objects generated by the component workbench.
p.s.
I've already search the forum but can find any relevant topic related to my request. If you have any known related topic, It would be highly appreciated.
Thanks and regards,
JP

Dear Syed,
   You can do many things in table maintenance screen like validation of some field, making some field required or displayed etc.
   For auto increment you have to use Number-Ranges. FM NUMBER_GET_NEXT is helpful in this case.
   Where to write the code??? The Function-Group you have made. There will be includes. You can easily locate the place to write these codes.
   Caution point is that if you re-generate the table maintenance then all code will be gone.
