Error: Target or source of mapping are null

Dear CAF experts,
I created one composite application project which has one entity and an
External Service (WebService). This entity has two fields "userName"
(shortText) and "password" (shortText). It has all CRUD methods and a
"logIn" method, which takes userName and password as input and gives
back the userEmailId as the response. I have defined this mapping (
between the attributes of the entity and the parameters of the
WebService method LogIn ) in the datasource tab of the entity. I marked
the entity as remote enabled and created a web service using it. Then I
deployed the CAF project to the J2EE engine and configured the WSDL URL
and the End point URL for the WebService in the "External Service
Configuration" application.
Finally I tested the service using the "Service Browser" application. It
simply throws the exception "ERROR. Target or source of mapping are
null!:".
Have I missed anything here? Any leads..?
Thanks,
Bala

Rene,
As mentioned aleady I've an attribute called "response" that is mapped to the userEmailId of the service.
The error in the browser is simply the same as the subject of this thread. i.e. "Error: Target or source of mapping are null"
The full exception is
com.sap.caf.rt.exception.DataAccessException: Target or source of mapping are null!

Extraction error "Target cost version in controlling area does not exists"

Hi Gurus,
I am trying to pull some data from a SAP OLTP system into SAP BW 710 system, using extractor "0CO_PC_02". The data load is failing with the below error message:

It works with jdev/adf 11.1.1.1.4. only with jdev/adf 11.1.1.1.5 (JDEVADF_11.1.1.5.0_GENERIC_110409.0025.6013) we're having this error. FacilitySummaryVO doesnt have primary key attribute.
Data got populated to VO programmatically
All VO attribute value updatable value is always

Hi,
hard to say. Actually the "node" variable reference is only available during tree rendering. So if you have any reference to the "node" variable that is invoked after tree rendering then this would explain the exception

Mapping multiple source value to one target value in value mapping

Hello experts,
In my scenario, i need to map more than one source value to one target value in value mapping. Like:
1 TenderPickup
2 TenderLoan
7 TenderPickup
101 TenderPickup
102 TenderLoan
107 TenderPickup
But when I enter the same target value for the second time and try to save it, it gives me an error saying value mapping already exists.
But this should logically be allowed. How can this be done. Please provide a solution.
Thanks,
Yash

Hi Prabhu,
When i right click on the target field, it gives me only 3 options:
1) Insert Row
2) Delete Value Mapping
3) Value Mapping in all agencies
I dont see nay option for duplicating rows.
What I hae done is in ID i clicked on TOOLS and then VALUE MAPPING. I checked the option "Value Mapping Agencies" and gave my source and target agencies detials. Then i clicked on DISPLY and in the next page I have 3 columns - Value for <source agency>, Value for <target agency> and Group name.
When I give duplicate values in the column Vlaue for <target agency>, it doesnt allow me to and if i right click in this column, i get the above mentioend options.
Please point out where i m going wrong.
Thanks,
Yash

Searching a Field In Source or Target Message in Message Mapping

Hey Guys,
I came accross this peculiar behaviour and it keeps bugging me , I could search any field in source or target message in message mapping in PI 7.0 by copying the path( /ns1:MaestroAcreedores/Acreedores/ClaveDeGrupo or any idoc field /FIDCCP02/IDOC/E1FIKPF/BUDAT ) but in PI 7.1 i cant , its giving me an error String /ns1:MaestroAcreedores/Acreedores/ClaveDeGrupo not found , i can only search the field independently.Can anyone please help me out in this.

Hi
I am not sure whether it worked in 7.0 or not, but having checked myself i can confirm that it is not working in 7.1 in my system also.
For alternative, you can check by changing into source text view where it will display as xml. Here when you search the keyword, it would display you the hierarchy better than normal view.
I dont think there is any other alternative. although I would say in the worst case scenario you would not have more than 10-15 occurrences of same element in an idoc.

Mapping constant values to the target data source columns

Hi
A Target data source has only two columns(RPT_NAME, RPT_LEVEL) and both of them are constants and mapped as follows
WITH TEMP1 AS
(select 'AS' as A from dual
union
select 'IS' as A from dual
union
select 'ED' as A from dual
select t.A as RPT_NAME, 'INV' as RPT_LEVEL from TEMP1 t
Here there is no source tabel involved for mapping and gnerating a from query.
Kindly let me know hoto map this table.
Thanks

Hi Amit
Is there a way we can create an intermediary staging table or model or view in ODI itself, the business requirements are such that the source and the target databases cannot change/include any other view or table .

Mapping of target data source

hi all,
while mapping the target datasource column we just write the column name in the mapping area and the query will automatically be generated.
but i want to write my own query in the mapping area.
how can i do this?
means i am not able to write the 'from table_name' statement in the mapping area.
please give any solution.
regards,
prateek.

hi,
thanks for rplying.
if i put the where condition at the source database using filter then all the data will be filtered.
but in my case the where condition is required only when i am inserting the data to target.
if i put the filter at the source then the whole answer will get filtered.
and one more thing, while inserting the data to the target datastore we can execute the query only on one of the source data store.
the value that i want to insert in the target column requires a query to get executed on two tables(source datastore).
is there any way to execute that query on more than one or two datastore?
can u please tell me that how to change the filter condition at the interface level?
thanks and regards,
prateek.

Error in generating data source from planning area

Hi experts! I have an error while making data source from planning area:
after the screen when i fill in the data source name (Window name: Generate export data source) i have the SYNTAX_ERROR Message:
Syntax error in program /sapapo/cl_im_extract_ex======cp
the main reason: the type /BI0/9A0IVWKNDGD is unknown
what you can suggest to solve this problem?
Thanks.

Dear Andrey Kudriavzev,
The reason is the program is trying to use the datatype '/BI0/9A0IVWKNDGD' which does not exist in the system.
Go SE11 to cross check if it exists. Check dataelement radiobutton -> enter /BI0/9A0IVWKNDGD -> Choose display option. You would need to create this datatype in the system. I feel there must some OSS Note related to this.
Search for an OSS Note. Raise one if you cannot find the relevant notes.

Hi,
If agent is installed on the VMM server, it will collect the information and send it to SCOM server. The event indicates the SCOM agent tried to access the registry key that was included in the User Profile but failed.
Please specify a local account or domain account as the SCOM action account for a test.
