Removing/updating data through CAF entity service
Does anyone know a way to remove/update data through a CAF entity service from a web dynpro which uses the webdynpro model of the CAF project ?
Hi Nicolaij,
This example describes how UPDATE and DELETE works under SP8.
Hopefully it helps.
Regards
Kamil
UPDATE of entity called "Bank"
=======================
ABank recordBank;
recordBank = BankServiceProxy.read(000000024);
recordBank.setCountryId(Germany);
IAspect aspectList = recordBank.getAspect();
aspectList.sendChanges();
DELETE from entity called "TransferID"
============================
ATransferID recordTransferID;
recordTransferID = TransferIDServiceProxy.read(123115651);
IAspect aspectList = recordTransferID.getAspect();
IAspectRow aspectRow = aspectList.getAspectRow(0);
aspectList.removeAspectRow(aspectRow);
aspectList.sendChanges();

How to design CAF Entity service?
hello,
here is my question.
how to design CAF Entity service?
i got employees data and departments data.
an employee can join over one department, and of course, a department had many employee.
in tradition RDBMS(relational database management system), i'll create three tables and named "Employee", "Department" and "DepEmp". the table "DepEmp" is a kind of table for N to N relaction.
but when i use CAF's entity service, i can't do like RDBMS.
i can create three entity services, named "Employee", "Department" and "DepEmp". i can make service refence(pull service from left side of windows), but the information about Key(in properties) cannot be "true".
how can i do?
is there a different normalization way i have to learn.thank you so much, it really help.
but when the issue more complicated.
a employee can join multiple departments, and he/she got different job title in each department. case will like fallow.
Vic is a software engineer in XX company's IT department, and he is a MIS engineer in XX company's HR department.
the db( i'm sorry for take this for example) structure will like..
=======================================
table:employee
column:
employeeCode PK
name
phone
table:department
column:
departmentCode PK
name
location
table:jobTitle
column:
titleCode PK
name
description
table:deptEmployee
column:
employeeCode PK FK
departmentCode PK FK
titleCode PK FK
=======================================
my SAP NetWeaver Developer Studio is version 7.0
1. how i make sure that three keys be mapped each other?(empCode,deptCode,titleCode)
2. is there have any "IUD abnormality" risk?
3. if there have, how can i avoid it?
thank you again, i'm sorry for ask much, because the way to design CAF Entity Service is that i didn't learn before. it really make me confused.
have a nice day -
How to use a structure in CAF entity service
Hi All
I want to use a structure as datatype of a complex attribute in a CAF entity service. I tried to use a dictionary structure created in the dictionary part
of the CAF project and added it to the public part of this DC.But I can't find it in the list of data structures while trying to mention datatype for a complex attribute in an entity service. Can any body suggest how to do it.
Cheers
SudipHello Sudip,
You can create a complex structure by doing the following:
1. From the Attributes Tab, right click on your Entity and select "Create Attribute"
- Enter an attribute name and description
- select "Complex Attribute" checkbox
- select "Finish"
2. Right click on the newly created complex attribute and select "Create Sub Attribute". Do this for each attribute in your structure.
This complex structure can now be used in your CAF application and also CAF UI patterns.
Creating complex attributes from the data dictionary is only usually used for creating enumeration types. When doing this, you have to use the CAF enumeration editor to populate the values. The "How to guide" that Jan refers to describes this.

CAF DB Update for CAF Entity Service from Web Dynpro
Hi all,
I have created an entity service in CAF called Contacts which contains the following attributes.
phoneNo
cellNo
emailID.
Another entity service called "Person" is created. This contains the following attributes.
personId
personName
personAddr
contactsRef. (Cardinality -> 0..n , Relational Type -> Composition)
That means Contacts entity service is used within Person entity service. Now it is working fine within CAF service browser. Now the Web Dynpro DC of CAF application is used within another custom Web Dynpro DC project. I want to store data from Web Dynpro.
Within the context of component controller of Web Dynpro the structure is like
APerson
|_ personId
|_ personName
|_ personAddr
|_ contactsRef
|_ phoneNo (Under contactsRef)
|_ cellNo (Under contactsRef)
|_ emailID (Under contactsRef)
So I have written the following code within web dynpro custom method.
APerson person = PersonServiceProxy.create();
java.util.List ls = new ArrayList();
for(int i=0; i<4;i++)
AContacts contact = ContactsServiceProxy.create();
contact.setCellNo("9092130156");
contact.setEmailID("[email protected]");
contact.setPhoneNo("432258");
contact.getAspect().sendChanges();
ls.add(contact);
person.setRelatedModelObjects("contactsRef",ls);
person.setPersonID("9999");
person.setPersonName("xyz");
person.setPersonAddr("ABC, KOL");
wdContext.nodeAPerson().bind(person);
person.getAspect().sendChanges();
CAFServiceFactory.getServiceFacade(idendityDefinition.class);
After saving the data from Web Dynpro I am trying to test it from CAF service browser. But I am getting only the parent row. I mean only the value of personId, personName and personAddr fields which I have stored from Web Dynpro. But no value is coming within the table for Contacts entity service for composition relation.
Could anybody help me how can I solve my problem?
Thanks & Regards

Chandan JashHi Chandan,
Can you do person.getRelatedModelObjects() and get the contact object, to check whether it is null, also check in the CAF DB whether the data you entered is present.
I am not sure the code is actually adding the contact model object to person.
Go thru this SDN Blog on usage of the CMI API's, there is a link for CMI documentation in it which might help you get the right code for adding the contact object.

Problem in data source mapping - CAF entity service.
Hi,
I created an external service for the bapi given below.
It has 2 tables as input parameters.
In entity service I created attributes(for input parameters) for table1 and table2. but in data source i couldn't map more than one attribute to the MATNRSELECTION and PLANTSELECTION.The attributes of the bapi are under the same collection.
I'm using NWDS version 7.0.06.
BAPI_MATERIAL_GETLIST (To List all Materials for a Particular Plant)
Input Parameters:
Table1: MATNRSELECTION
MATNRSELECTION-SIGN
MATNRSELECTION-OPTION
MATNRSELECTION-MATNR_LOW
Table 2: PLANTSELECTION
PLANTSELECTION-SIGN
PLANTSELECTION-OPTION
PLANTSELECTION-PLANT_LOW
Regards,
Shobhendrain your entity if you did create 2 attributes for one material number and one for plant, you can map them to the corresponding MATNRSELECTION-MATNR_LOW and PLANTSELECTION-PLANT_LOW.
For the sign and option, you should uncheck the IsNull parameter in the "Entity to External Operation parameters" mapping window of the Datasource Tab of your entity. And you should set default values like sign = I and option = EQ or something like that.
But if you want to pass a list of material numbers or plants, I do have a recollection from last year experiments of some limitation using collections as input parameters. maybe somebody else had better success with that -
How to sort web dynpro table wich data bind to CAF Entity Service
Hi
I created UI Table based on Model Node (CAF Entity).
When I try to sort this Table with using TableSorter, I get following in the trace log:
The error is: com.sap.caf.rt.exception.CAFBaseRuntimeException: Aspect does not support changing rows via its list interface
Have I met CAF limitation, or do I do something wrong?Hi Nikolai,
if you use the implementation
<code>
IServiceFacade serviceFacade = CAFServiceFactory.getServiceFacade(ts2Definition.class);
</code>
it means you use the typed access.
Possible in this sneak the
<code>
IServiceFacade serviceFacade = CAFServiceFactory.getServiceFacade();
</code>
does not work.
Try the following way - it must work.
<code>
private IServiceFacade getServiceFacade() {
final String method = "getServiceFacade()";
entering(method);
if (m_serviceFacade==null) {
try {
CoolConnectionProperties properties = new CoolConnectionProperties()
public String getCoolHost()
return "caf";
m_serviceFacade = CoolUtils.getServiceFacade(properties);
} catch (CoolConnectionPropertiesException e) {
wdComponentAPI.getMessageManager().reportException(e.getMessage(),false);
CAFUIPublicLogger.traceThrowable(Severity.ERROR, method, e) ;
} catch (CoolUtilsException e) {
wdComponentAPI.getMessageManager().reportException(e.getMessage(),false);
CAFUIPublicLogger.traceThrowable(Severity.ERROR, method, e) ;
exiting(method) ;
return m_serviceFacade;
</code>
Also do not sort in query. Sort the model node after you aspect binded. Use the method
node.sort(your_comparator) ;
the comparator like this:
<code>
public class YourComparator implements Comparator
public int compare(Object o1, Object o2)
IWDNodeElement nodeElement1 = (IWDNodeElement) o1 ;
IWDNodeElement nodeElement2 = (IWDNodeElement) o2 ;
String name1 = nodeElement1.getAttributeAsText(_attrName) ;
String name2 = nodeElement2.getAttributeAsText(_attrName) ;
if (name1 == null)
return -1 ;
if (name2 == null)
return 1 ;
if (_direction == "up")
return name1.compareToIgnoreCase(name2) ;
else if (_direction == "down")
return -name1.compareToIgnoreCase(name2) ;
return 0 ;
public void initilize(String attrName, String direction)
_attrName = attrName ;
_direction = direction ;
private String _attrName ;
private String _direction ;
</code>

Error Updating Data using a Web Service from BPM
Hi there,
I'm trying to update data in an oracle database using a webservice created in DSP and get the following errors. It appears that BPM is unable to find a name, but I'm not sure what name this is referring to. The web service is straight forward and takes in the original and current objects as arguments. I can successfully call the query and insert web services and have double checked my code for the update web service but can't figure out why this is failing. Any idea on why this error might be occurring, or any pointers on what I need to be aware of?
Caused by: Task '0' in activity '/PlanSubmittal#Default-1.0/Interactive[ViewEditPlan]' for instance '/PlanSubmittal#Default-1.0/1/0' could not be successfully executed. The task failed while executing method 'AddEditWell_Router'.

Table Name Issue of CAF Entity Service
Hi All
I have a problem in the following scenario :--
I have created a CAF project named xflit_01 in local development. Another CAF project xflit_02 is created in local development of another machine's NWDS but both the project has a same entity service name,'Flight'. But one interesting observation from persistency tab of the entity service'Flight' is that for tables generated for both the entity services are same name, 'XAP_XFL_FLIGHT0001' where "XAP_XFL_" is namespace and "FLIGHT0001" is names. Both entity services are mapped with same external service.
Next I have deployed that two projects such as xflit_01 and xflit_02 in same central WAS from different machine's NWDS one by one. but how two tables with same name, 'XAP_XFL_FLIGHT0001' would be handle by WAS? But after the deployment we need to configure external service. So in External Service configuration window we are getting error when the link Service Registry is clicked.
Any idea will highly be appreciated.
Thanks
ChandanSolved by myself. Reason is for same db and CAF table naming convention

Problem when creating CAF Entity Service finder Methods
Guys,
Can any one please suggest me appropriatly to the below problem.
I am using NWDS 7.06. I have no problem when creating CAF project, Application Service and Entity Service even.
But in the Entity Service:
1. Add a string or longtext attribute.
2. try to create a custom finder method in operations tab, during that operation i am not finding the attribute which i have created in step1.
That means i am not able to create the my own finder methods with parameters.
I was able to do that in some version long ago but i have forgotten that NWDS version.
summary of Problem Is: " Cannot create custom methods with custom parameters in Entity Service"
Can you please suggest me the right version or a solution to this problem on urgent basis please.
I promise you that i will give you full points to you who ever gives me the right solution.
Please mail your suggestions to [email protected]Guys,
I have solved the problem successfully. Thanks for your attention. -
How to read CAF entity services in BCO
Hello,
I try to read an entity service out of an background callbale object.
For this i added the the public part of the webdynpro DC of the entity service as used DC to my bco. I did this as well with the library, including my bco.
The problem is, that the included class cant be found in the deployed bco.
I get the NoClassDefFoundError while executing the bco.
Any hints how to reference my entity service?
Regards
RobertHi,
If I understand your problem then I can tell that you are trying to make a link in between two Entity service of two different projects. If I am correct then I can tell you that please publish the DC part of your EJB project not the Web Dynpro. Then you use that in another projects (ejb sub project) DC dependency part. Then try it.
If any problem please let me know.
Thanks

How to create index attributes in CAF Entity Service
When one creates an entity service with external persistency (local persistency on the persistency tab is unchecked) you have to create at least one "key" attribute. However, how do you create "index" attributes to improve performance. Currently, if you add custom key you must select "key" checkbox in attribute wizard when creating an attribute and this key field must be unique. This is not what I am looking for. I'd like to create a few custom keys that the contents allow duplicate.
Hi Tom,
This is a very valuable question. Yes, you can add an index for specific fields to the generated database table. You can do in the NWDS, navigate to the dictionnary view and open the corresponding database table. Now you can add an index and assign database field(s) to this index.
However: you must be aware that, if the entity is changed (i.e. new parameters are added), the database table is re-generated and the indices are lost.

How to update data from a web service
Hi all,
I have a webservice that returns some data as e4x type. I
pull the data i need and put it into an object. I manipulate that
data, then I want to write it back with another webservice. I get
serialization errors when I call the update method. I must be doing
something wrong here. Can anyone help?

Problem while updating Data through IDOC
hi!
I have declared an Internal Table like a structure which has 10 fields.
To generate Idoc i need to pass the records from Internal Table to EDIDD-SDATA.
Since SDATA is a string of Char 1000, i'm concatenating all the columns of internal table to a variable.
In debug mode all the fields size are adopting to its correct size.
but after generating the IDOC and view through WE02 the data are miss placed bz of inclusion of space.
Example:
field1 (Size 4) - ABCD
field2 (Size 10) - 0000001234
field3 (size 10) - 09.02.2010
field4 (Size 6) - _12345
field5 (Size 4) - 6 AB --> missed character is continuing in next field after a space data of its corresponding field starts
field6 (Size 3) - C 2 -->missed character is continuing in next field after a space data of its corresponding field starts
Tried by suppressing the space. CONDENSE NO-GAPS. . . .it dnt help me

KvHi,
Populate it this way :-
LOOP AT IT_DATA into wa_data.
CALL METHOD CL_ABAP_CONTAINER_UTILITIES=>FILL_CONTAINER_C
EXPORTING
IM_VALUE = WA_DATA
IMPORTING
EX_CONTAINER = EDIDD-SDATA
EXCEPTIONS
ILLEGAL_PARAMETER_TYPE = 1
others = 2 .
append EDIDD.
ENDLOOP.
