BPM "Expression must return multiline value"

Hi
i was Creating a scenario file to file Message Split using BPM. in that i have done all the IR part and after that i created integration process.but when i m check this Integration process, i got an error like "Expression must return multiline value" it display into Receiver Determination.
Can somebody who help me...
regards
Bhaumik

check for the following:
1. in your messages tab in MM and IM you have changed the occurance for the multiple message.
2. Do a f7 on your BPM and confirm it is error free.
3. chk your transformation step have you given the correct container variable there ? (chk for the correct multiline or non-multiline interface)
4. recheck wherever the multiline container is used (in case of 1:N or N:1 u need to have the multiline option)
also has your process made an exit from the BPM ?

Expression must return the interface type in Transformation Step in BPM

hi,
We are getting below while activating the IP,
Expression must return the interface type SI_Send_AA
Expression must return the interface type SI_Get_AA
No semantic errors found
We have a Transformation Step in BPM,
In OM, Source is SI_Send_AA and Target is SI_Get_AA
Also Container variable points to the same Abstract SI's.
Few Thread's for Same are error are:
Error in BPM

Error while compiling Business Process
Even after checking these i am getting this Exception.
Please Help!
Thanks,
Mayank

Also Container variable points to the same Abstract SI's
Are you sure that you are using Abstract Message Interfaces only and that these are referring to relevant container variables.
Normally it happens that there is some mis-match between the message types/ interfaces that we use in the mapping and that we use in the BPM.
If still not solved, then delete the Transformation step --> save --> activate......then again Edit the BPM to include the Transformation Step.

Expression must return the interface type

Dear XI experts,
My scenario is ;
The input parameter for the RFC is send through a file and the response from the RFC comes into XI which is then written into a File (dummy). Finally I want to have Transformation(Message Mapping to IDoc) and send to Target system.
The diagram of the following is shown below;
http://photos1.blogger.com/blogger/3087/1595/1600/6.jpg
I am getting Error in Transformation Step, EXPRESSION MUST RETURN THE INTERFACE TYPE <Target message>. 

Pls advice, Anybody ??

Hi Faith,
->This error occurs when the interface mentioned in the interface mapping and in the container difference.
->Here in your case the target Message Interface in the Interface Mapping and the Interface of the container modify are different. Do check that.
Hope this helps.

SSRS expression returns #error value in some cells

Hello,
What do you think below expression sometimes return #error value in ssrs.
=SUM(Fields!X.Value / 100 * DateDiff(DateInterval.Day,Fields!s_date.Value,Fields!e_date.Value)) /
IIF( SUM(DateDiff(DateInterval.Day,Fields!s_date.Value,Fields!e_date.Value)) = 0
,nothing
,SUM(DateDiff(DateInterval.Day,Fields!s_date.Value,Fields!e_date.Value))

Hi,
Use below expression to overcome the issue:
=
IIF( SUM(DateDiff(DateInterval.Day,Fields!s_date.Value,Fields!e_date.Value)) = 0
, 0
, SUM( Fields!X.Value / 100
* DateDiff(DateInterval.Day,Fields!s_date.Value,Fields!e_date.Value)
SUM(DateDiff(DateInterval.Day,Fields!s_date.Value,Fields!e_date.Value))

BPM collection pattern - Expression must not return a multiline value

Hi,
I am trying to create an integration process to collect messages - when I run the check function I get the message 'Expression must not return a multiline value' - I have checked everything and cannot find what is causing this message. When I click on the message I get taken to the transformation step properties.
Any ideas?
Regards
Ian

HI,
Your Interface Mapping should be of N:1 type.
i.e occurence of your source message should be of 0..unbounded and target message should be 1.
Once you change Interface Mapping, you need to change occurences of corresponding Message Maaping.
Use this interface mapping in your Transformation Step in BPM, where you collect all the messages.
Hope this helps,

Moorthy

Error: Expression must not return a multiline value

Hi all,
I am doing a file to file scenario. My input file has more than one record. I have to validate for each of these records and send back the erroneous records in a file to the source folder.
I am using BPM for this. In my BPM, i have some multiline container elements. When i try to activate my BPM, i am getting an error saying: Expression must not return a multiline value.
Can anybody tell me why this error is coming? Also i want to know what type of mapping i have to do to split my source file.
Regards,
Divija.

"Can anybody tell me why this error is coming? Also i want to know what type of mapping i have to do to split my source file."
Go through the following blogs which give step-bystep approach for split mapping using BPM:-
1. /people/sudharshan.aravamudan/blog/2005/12/01/illustration-of-multi-mapping-and-message-split-using-bpm-in-sap-exchange-infrastructure
2. /people/narendra.jain/blog/2005/12/30/various-multi-mappings-and-optimizing-their-implementation-in-integration-processes-bpm-in-xi
Also, you might want to look at this, where a BPM is not required..i think you can avoid a BPM altogether if you have very little validation..

Expression must not return a multilne value

Hi
I am trying to create PurchaseOrder message via BPM.
The target MI has:
One Header record
Unbounded Items records
In BPM, Fork of 2 braches is created to recieve Header, another branch use looping to received Items and store into ItemsList
After the fork, a tarnsformation is use to create target MI, which the source contains:
Header (single record) and
ItemList (multiline with Item record)
Now the problem, when I do a check, I always hit the error: "Expression must not return a multilne value"
However if use :
Header (single record) and
Item (single Item record)
OR
HeaderList (multiline record) and
ItemList (multiline Item record)
It does not generate this error.
I seems the tarsnformation does not allow mixing of "Multiline" and "Singleline" for N:1 transformation???
Please advise

Help with an SQL Expression - Return field value where Datetime is Min or First datetime

Hello,
I'm extracting results for a patient population.
I have 6 SQL expressions that pull back the first date for specific procedures or Medications being ordered.
These Expressions work perfect - One of the expressions return the first time a lab was ordered.
I'm using SQL that return
Min(OrderDatetime)
From OrderTable
Where
LABCode = XXX
I've now been ask to return the value of this lab result.
Question: How do I write an SQL expression that return the Lab value of the Min(OrderDatetime)
Example Data
PATID* LABID * OrderDatetime * ResultValue
Pat1*133 * 12/12/2013 11:00:pm * 77

SSAS- DAX expression : Is there any DAX function that can return multiple values ?

Hi,
Iam in search of a DAX function that can return multiple values as result. please find below scenario where i want to implement the same.
I have three Tables: Table A (typeid, Cost, Qty ) ,Table B (typeid, Cost, Qty ) , Table C ( typeid,Typename ) .
Table A                                       Table B
Table C
type id cost Qty             type id   Cost    Qty
typeid typename
1          100    100                3         300
300                  1           aa
2           200    200                4          400
400                  2           bb
                                                                                         3           cc
                                                                                         4
dd
i have to club cost and Qty of two tables(four measures) as two measures in the UI report. There are more columns in these tables that restrict the UNION of the tables.(for the sake
of understanding , i have not mentioned the othr columns). In the UI report(Execl 2013-power pivot) iam plotting these measures against the
Table C.Typeid. Hence the measures drill down against each
Table C. Typeid as shown below:
Typeid Table A.cost Table A.Qty TableB.cost TableB.Qty
1              100             100
2              200             200
3
300             300
4
400             400
My requirement is to club these measures so that the report will be as below
Type id cost   Qty
1          100    100
2          200    200
3         300     300
4        400      400
Since i cannot club these in model,as a work around, i created a calculated measure in excel(Analyze tab->Calculations->olap tools->calculated measure) with the condition as below:
new cost = IIF (ISEMPTY(TableA.cost)="TRUE",TableB.cost,TableA.cost)
new Qty = IIF(ISEMPTY(TableA.Qty)="TRUE",TableB.Qty,TableA.Qty) and dragged these new measures into the report. It was working fine as expected.
But this functionality of Creating calculatedmeasure in excel report is possible only in 2013 excel version.
Now the requirement is to get the same result in 2010 excel. Can you please help me in implementing the same in 2010 excel? or any other alternative method to bring the columns in model itself. I tried to create a measure in table A with DAX expression as
: new cost :=CALCULATE(SUM(Table B.cost),ISBLANK(TableA.cost)) -> but this will return only 1 result .i need Sum(Table A.cost) also if it is not blank.
Thanks in advance

You can use SUMX ( 'Table A', 'Table A'[Cost] + 'Table B'[cost] )
However, if you install the latest version of Power Pivot in Excel 2010, it supports the ISEMPTY function, too.

[UIX] How To: Return multiple values from a LOV

Hi gang
I've been receiving a number of queries via email on how to return multiple items from a LOV using UIX thanks to earlier posts of mine on OTN. I'm unfortunately aware my previous posts on this are not that clear thanks to the nature of the forums Q&A type approach. So I thought I'd write one clear post, and then direct any queries to it from now on to save me time.
Following is my solution to this problem. Please note it's just one method of many in skinning a cat. It's my understanding via chatting to Oracle employees that LOVs are to be changed in a future release of JDeveloper to be more like Oracle Forms LOVs, so my skinning skills may be rather bloody & crude very soon (already?).
I'll base my example on the hr schema supplied with the standard RDBMS install.
Say we have an UIX input-form screen to modify an employees record. The employees record has a department_id field and a fk to the departments table. Our requirement is to build a LOV for the department_id field such that we can link the employees record to any department_id in the database. In turn we want the department_name shown on the employees input form, so this must be returned via the LOV too.
To meet this requirement follow these steps:
1) In your ADF BC model project, create 2 EOs for employees and departments.
2) Also in your model, create 2 VOs for the same EOs.
3) Open your employees VO and create a new attribute DepartmentName. Check selected in query. In expressions type (SELECT dept.department_name FROM departments dept WHERE dept.department_id = employees.department_id). Check Updateable always.
4) Create a new empty UIX page in your ViewController project called editEmployees.uix.
5) From the data control palette, drag and drop EmployeesView1 as an input-form. Notice that the new field DepartmentName is also included in the input-form.
6) As the DepartmentName will be populated either from querying existing employees records, or via the LOV, disable the field as the user should not have the ability to edit it.
7) Select the DepartmentId field and delete it. In the UI Model window delete the DepartmentId binding.
8) From the data controls palette, drag and drop the DepartmentId field as a messageLovInput onto your page. Note in your application navigator a new UIX page lovWindow0.uix (or similar) has been created for you.
9) While the lovWindow0.uix is still in italics (before you save it), rename the file to departmentsLov.uix.
10) Back in your editEmployees.uix page, your messageLovInput source will look like the following:
<messageLovInput
 model="${bindings.DepartmentId}"
 id="${bindings.DepartmentId.path}"
 destination="lovWindow0.uix"/>Change it to be:
<messageLovInput
 model="${bindings.DepartmentId}"
 id="DepartmentId"
 destination="departmentsLov.uix"
 partialRenderMode="multiple"
 partialTargets="_uixState DepartmentName"/>11) Also change your DepartmentName source to look like the following:
<messageTextInput
 id=DepartmentName
 model="${bindings.DepartmentName}"
 columns="10"
 disabled="true"/>12) Open your departmentsLov.uix page.
13) In the data control palette, drag and drop the DepartmentId field of the DepartmentView1 as a LovTable into the Results area on your page.
14) Notice in the UI Model window that the 3 binding controls have been created for you, an iterator, a range and a binding for DepartmentId.
15) Right click on the DepartmentsLovUIModel node in the UI Model window, then create binding, display, and finally attribute. The attribute binding editor will pop up. In the select-an-iterator drop down select the DepartmentsView1Iterator. Now select DepartmentName in the attribute list and then the ok button.
16) Note in the UI Model you now have a new binding called DCDefaultControl. Select this, and in the property palette change the Id to DepartmentName.
17) View the LOV pages source, and change the lovUpdate event as follows:
<event name="lovSelect">
 <compound>
 <set value="${bindings.DepartmentId.inputValue}" target="${sessionScope}" property="MyAppDepartmentId" />
 <set value="${bindings.DepartmentName.inputValue}" target="${sessionScope}" property="MyAppDepartmentName" />
 </compound>
</event>18) Return to editEmployees.uix source, and modify the lovUpdate event to look as follows:
<event name="lovUpdate">
 <compound>
 <set value="${sessionScope.MyAppDepartmentId}" target="${bindings.DepartmentId}" property="inputValue"/>
 <set value="${sessionScope.MyAppDepartmentName}" target="${bindings.DepartmentName}" property="inputValue"/>
 </compound>
</event>Thats it. Now when you select a value in your LOV, it will return 2 (multiple!) values.
A couple things to note:
1) In the messageLovInput id field we dont use the .path notation. This is mechanism for returning 1 value from the LOV and is useless for us.
2) Again in the messageLovInput we supply _uixState as an entry in the partialTargets.
3) We are relying on partial-page-refresh functionality to update multiple items on the screen.
Im not going to take the time out to explain these 3 points, but its worthwhile you learning more about them, especially the last 2, as a separate exercise.
One other useful thing to do is, in your messageLovInput, include as a last entry in the partialTargets list MessageBox. In turn locate the messageBox control on your page (if any), and supply an id=MessageBox. This will allow the LOV to place any errors raised in the MessageBox and show them to the user.
I hope this works for you :)
Cheers,
CM.

Thanks Chris,
It took me some time to find the information I needed, how to use return multiple values from a LOV popup window, then I found your post and all problems were solved. Its working perfectly, well, almost perfectly.
Im always fighting with ADF-UIX, it never does the thing that I expect it to do, I guess its because I have a hard time letting go of the total control you have as a developer and let the framework take care of a few things.
Anyway, I'm using your example to fill 5 fields at once, one of the fields being a messageChoice (a list with countries) with a LOV to a lookup table (id , country).
I return the countryId from the popup LOV window, that works great, but it doesn't set the correct value in my messageChoice . I think its because its using the CountryId for the listbox index.
So how can I select the correct value inside my messageChoice? Come to think of it, I dont realy think its LOV related...
Can someone help me out out here?
Kind regards

Returning multiple values from a function

Hello everyone,
I am pretty new to actionscript and flex and one thing i am not entirly sure it is done is how to get the value in actionscript when returning multple values.
for example i have the following function:
public function sayhello():string
     var hello:String="hello World";
     return hello
var myvalue:String=sayhello();
trace(myvalue);
How do go about getting the values of two returns:
public function sayhello():string
     var strhello:String="hello";
      var strWorld:String="World";
     return strhello,strWorld;
var myvalue1:String=?????
var myvalue2:String=???

To solve this problem you must use a object for storing complex return value.
You can do it using inline anonymous object:
public function sayhello():Object
     return {strHello: "hello";strWorld: "World"}
and accesing result as:
var obj:Object = sayhello();
var strHello:String = obj.strHello;
You may also create a custom class
class HelloWorldResult{
     public var strHello:String;
     public var strWorld:String;
and return a new instance of this class from your method:
public function sayhello():HelloWorldResult
     var hwr:HelloWorldResult = new HelloWorldResult();
     hwr.strHello = "Hello";
     hwr.strWorld = "World";
     return hwr;

Return multiple values from a method

For a school project I have to make a parameter-less constructor that can input values from the keyboard and calculate those values. Now that I have the values how do I return them? I need to return 3 values from this parameter-less method.
I hoope someone can help.

Here is the wording of the assignment. I have copied and pasted it word for word:
"Declare and use a no-argument (or "parameter-less") constructor to input the data needed, and to do the calculations."
Any advice???Find a teacher who isn't an idiot. That sentence is vague ("to input the data needed"? Does that mean that it's supposed to query the user (which is terrible) or that it's supposed to encapsulate the data as hardcoded values, or what?) and is a bad design. Constructors shouldn't do this sort of thing.
Ok I have done that part and now I want to retrieve the values of the calculations. How can I get those values out of that method What do you mean "that method"? Constructors aren't methods, and they don't return values.
I suppose you could define a class whose constructor queries the user, and which would have a method to return values. That could be pretty simple; the method signature would be like this:
Set<Integer> getValues();
This seems like an advanced problem.It's not advanced; it's just garbage.
I can't post the code in hear because that may constitute cheating. I am allowed to discuss it verbally but I cannot share code, sorry.You can't get a lot of help then. We can't psychically see what you've done so far.
In conclusion: I have to have two methods. One method is a constructorConstructors aren't methods. If your teacher told you that they are, then he/she doesn't know what he/she is doing.
that has NO parameters that will get input from the keyboard (done) and do the calculations (done). The other method must print that values to the screen on separate lines (not done). I don't know how to get the values out of the method.If they're two methods in the same class, then the constructor just needs to store the user input into a field of the class, and the other method can read the values in that field.

PL/SQL function/Expression in a default value

Hi,
I want to generate a sequence number using oracle sequence and populate a field when user hits create button. I tried using PL/SQL expression in the default value of a field. What is the exact syntax for this. I tried this
:P18_PROJECT_NUMBER := MNT_PROJECTS_NUMBER_S.NEXTVAL;
Did not work.
select MNT_PROJECTS_NUMBER_S.NEXTVAL into :P18_PROJECT_NUMBER
from dual;
Did not work. Can anyone help me with this ?
Thanks
Naresh

Naresh - You should never say something "did not work" without saying what happened. It is useless otherwise.
