Excel Function to query BW using Web Services API

Hello,
I need to write an Excel function as an .XLA that will do the following:
It will be invoked like any other Excel function. E.g. =GetCost(param p1, param p2)
This function queries an InfoCube and must return a single numerical value for the Cell in Excel that the function is used in.
I have never done anything like this before. I have done a decent amount of reading to discover the best way to attack this. It seems like the best way to create this functionality is to:
1. create a web service in a BW function group with a function module that is RFC enabled.
2. I'm thinking the function module will use native SQL to query the InfoCube and pull the value and then somehow pass this value to a web service.
3. The value in the web service will be accessed through it's API in Excel/VBA.
I am not sure if this is best way to do this, or if it is even possible to do it this way. I was wondering if anyone could tell me if I am heading down the right path and possibly direct me to a tutorial or other information that would aid in accomplishing this. I have yet to find some type of proof of concept from beginning to end on how to do something like this. Any help would be greatly appreciated.
These are the documents I have found insightful so far:
How to build an XLA: http://www.fontstuff.com/vba/vbatut03.htm
If you can read a table and dump it into Excel then you can query an InfoCube? https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/c043d836-166c-2910-b99e-ae3633dec547

Thanks!

Query as a Web Service can't see .unx universes to use as data source?

Hi,
I created a Universe using Information Designer. The Universe is published on the server as *.unx.
With Query as a Web Service Designer, I connect to the server to create a query. However, in "Choose a universe as a data source for the query", I do not see the *.unx Universes, I only see *.unv Universes.
Both software are the latest version (XI 4.0).
Anyone know what is the issue here?
Thanks,

Hi there,
So in QaaWS tool, therefore, only UNV files are seen?
Regarding going through WebI Rich client > Web Services, how do I generate a URL?
In WebI Rich client this is already sourcing the Web Service (provided i already have a URL)...
I am confused with this.
Can someone please reply?

Query for job status using Web Services in BODI

Hello,
I am starting a Batch job in DI using Web Services, getting the following response from DI:

How can I know the status of the started job?
How can I know if the job execution finished with success or not?
I did not find in WSDL file any method to query for job or service status...
Thank you in advance,

Did you ever get this figured out? I am having exactly the same problem in code generated by VS, with the BAPIRET2 structure.
Any help you could provide would be greatly appreciated.

Query as a Web Service and In List

Hi,
Here is my scenario (Xcelsius 2008 Enterprise SP2):
- List builder object which returns multiple values
I want to use those values to filter a Query as a Web Service data connection (to BW based universe). How is that possible?
My web service contains a Filter defined as <Dimension> In List <Prompt>
I have tried the following:
1) Selected multiple rows in the Input Values/Read From section of the connection
2) Tried to concatenate the individual values using ; and , and then passing the concatenated values to the Read From section of the connection (as one cell)
1) works fine as long as I just select one value, but when I select multiple values, only the first one is used to filter the QaaWS
2) Does not work
Any ideas/suggestion on how to solve this?
Thanks in advance,
Jacob

Hello David,
I tried this feature of BI Services through WebI Rich Client. But I am having problem with sending values for Prompts using Xceslius. Below is the procedure I followed in developing a report and using BI web service to connect to Xcelsius.
1) Build a report in Web Intelligence rich client along with Query filters (Inlist, Optional Prompts).
2) Activate BI Service and publish the block after exporting the file.
3) Use the WSDL URL to connect to Xcelsius from Data Connection (Add as Query As Web Service and Import it).
4) Method: Get_ReportBlock_<Block name>,
    set input values <Enter_value_s_for_prompt>
        i) Valueofprompt (bind to single values, hard coded)
       ii) Index (leave blank, not binded)
5) set <refresh> as 1 (or true) and <getfromlatestdocumentinstance> as 0 (false)
6) Bind the output values to excel and pull a scorecard component to view the data.
7) Preview the dashboard and now I get this error
                Cannot Access external Data: String index out of range: -1
When I remove both the values inserted in step 5, I get complete data (prompt is not applied). I also have a doubt whether I can pass multiple values for the prompt without using + sign to duplicate the Prompt.
From some of the previous posts I came to know about Value formatting compatibility issue between BI Services and Xcelsius. Which is addressed with two fix packs
1) XI 3.1 SP2.5 (available since last March) for WebIntelligence Rich Client & BI Services, and
2) Xcelsius 2008 SP3.1 (available since last April).
Are these the up to date Fix packs available and will they solve my problem?
Where can I download them from (SAP Market place)? or from our SAP service consultant?

What is the best way to deploy application that uses web services?

Hi all,
I'm having some problems figuring out the best way to deploy our app now that we've switched over to using web services.
I'm fairly new to Java and web services. From what I understand, JNLP and WebStart are methods to deploy Java clients to users and not for creating war files and the like.
Here's a little background:
We have a large PowerBuilder/Oracle application. The db consists of over 500 tables and the client consists of several thousand PB components. A user creates "transactions" which contain a series of "sub-transactions" within. Most of the data is collected and stored locally in the client in a series of datastores. When the "finalize" happens, the records are validated and sent to the database.
We are in the process of moving each of the subtransactions (currently in the PB client) into subPROCESSES on a java project. We are using the JAX-WS framework to develop the web services in Netbeans. These web services aren't much more than remote xml as the messaging technology. For writing data back to the database, we are using the Java Persistence API to function outside of an EJB container but will shortly be migrating to the Glassfish application server to use several of the EJB container frameworks including the EntityManager.
We haven't attempted any type of deployment and are unsure of where to start. Any suggestions would be so helpful and appreciated!
Thanks!

It is for launching rich client GUI based (AWT, Swing, SWT..) applications onto the end-user's desktop.
There are some parts of JWS that might seem peripherally useful to the installation of a web-app., but it is really not a 'good fit'.

Novice Help with Creating Opportunities Using Web Services 2.0

Hello,
I recently took over our CRM integration services and was asked to push some data via our custom portal.
We use our portal to automate the creation of new opportunities in our Oracle CRM System.
The code was developed using Web Services 1.0
I was recently asked to add data to the "Parent Opportunity" field upon creation of a new Opportunity. Now I may be mistaken and if I am I will be very pleased, but it seems to me this field isn't available in 1.0
If I am mistaken and there IS a way to push data to the "parent opportunity" field using 1.0 Please completely disregard what I have typed below.
Upon looking at the WSLD for 2.0 I see "ParentoptyID" as an available field.
I took it upon myself to try and move this process over to 2.0 but I have hit a few major stumbling blocks. Here is the working code for 1.0:
Public Function CRMAddFinalShipmentOpportunity2(ByVal Session As Session, ByVal Subject As String, ByVal Type As String, ByVal Priority As String, ByVal Account As String, ByVal DueDate As String, ByVal Status As String, ByVal Description As String, ByVal AnnBudget As String, ByVal oppType As String, ByVal partNumber As String, ByVal currency As String, ByVal Territory As String, ByVal Owner As String, ByVal Opp As String) As String
Dim opportunity As nkkcrm.SiebelOpportunity20.Opportunity = New nkkcrm.SiebelOpportunity20.Opportunity
Dim input As New nkkcrm.SiebelOpportunity20.OpportunityInsert_Input
Dim results As New nkkcrm.SiebelOpportunity20.OpportunityInsert_Output
Dim strPriority As String = "1-High,2-Medium,3-Low"
Dim strType As String = "Call,Correspondence,Email,Event,Final Shipment - Book,Final Shipment - Special,Lead Follow-Up,Meeting,Opportunity Follow-Up,Other,Presentation,Quote Follow-Up,Sample Follow-Up,Service Request Follow-Up"
Dim strStatus As String = "Completed,Deferred,Waiting For Someone Else,In Progress,Not Started,Assigned,In Call"
CRMAddFinalShipmentOpportunity2 = ""
' Validate Data (CRM will validate if owner is valid)
If Owner = "" Then
AddError("Error: Missing Owner")
Exit Function
End If
If Subject = "" Then
AddError("Error: Missing Subject")
Exit Function
End If
If strType.IndexOf(Type) < 0 Then
AddError("Error: Invalid or Missing Type")
Exit Function
End If
If strStatus.IndexOf(Status) < 0 Then
AddError("Error: Invalid or Missing Status")
Exit Function
End If
If strPriority.IndexOf(Priority) < 0 Then
AddError("Error: Invalid or Missing Priority")
Exit Function
End If
If Not IsDate(DueDate) Then
AddError("Error: Invalid or Missing DueDate")
Exit Function
End If
Try
opportunity.Url = Session.GetURL()
opportunity.CookieContainer = Session.GetCookieContainer()
'Create the opportunity
Dim tmpAry(0) As nkkcrm.SiebelOpportunity20.Opportunity
input.ListOfOpportunity(0) = tmpAry
input.ListOfOpportunity.SetValue(New nkkcrm.SiebelOpportunity20.Opportunity, 0)
'Assign the opportunity Properties
input.ListOfOpportunity(0).Owner = Owner
input.ListOfOpportunity(0).OpportunityName = Subject
input.ListOfOpportunity(0).AccountName = Account
input.ListOfOpportunity(0).SalesStage = "Rebuy"
input.ListOfOpportunity(0).CloseDate = Date.Today
input.ListOfOpportunity(0).Territory = Territory
input.ListOfOpportunity(0).stProject_Name = "FINAL SHIPMENT REBUY"
input.ListOfOpportunity(0).SourceCampaign = "Rebuy"
input.ListOfOpportunity(0).OpportunityType = oppType
input.ListOfOpportunity(0).Revenue = AnnBudget
input.ListOfOpportunity(0).Description = Description
input.ListOfOpportunity(0).bRebuy = "Y"
input.ListOfOpportunity(0).ProductInterest = partNumber
input.ListOfOpportunity(0).plCurrency_Type = currency
'input.ListOfOpportunity(0).ParentoptyId = Opp
'insert the opportunity
results = opportunity.OpportunityInsert(input)
If results.ListOfOpportunity.Length > 0 Then
CRMAddFinalShipmentOpportunity2 = results.ListOfOpportunity(0).OpportunityId
End If
Catch webex As WebException
AddError(webex.Message)
Catch ex As Exception
AddError(ex.Message)
End Try
End Function
What changes might I need to make in order to make this function correctly using Web Services 2.0?
Currently I get the following errors- For every line of input.ListOfOpportunity(0) I get: '..cannot be indexed because it has no default property.'
Another example of an issue I'm running into is: 'SetValue' is not a member of 'nkkcrm.SiebelOpportunity20.ListOfOpportunityData'

We were able to make this work by re-modeling my code after a code sample I found that creates new Activities.
Here's my code in case it helps someone scanning these forums in the future (Disregard the Opportunity entries that are missing when you compare this to my earlier code- Those weren't relevant to making this work or not work, I simply am not using them now.):
Public Function CRMAddFinalShipmentOpportunity2(ByVal Session As Session, ByVal Owner As String, ByVal Subject As String, ByVal Type As String, ByVal Priority As String, ByVal DueDate As String, ByVal Status As String, ByVal Description As String, ByVal POValue As String, ByVal oppType As String, ByVal partNumber As String, ByVal currency As String, ByVal servername As String, ByVal pass As String, ByVal usrname As String) As String

How can I test my Query As A Web Service?

Hi,guru:
    I have created my Web Service based on universe which based on SAP BW query using Query As A Web Service Designer, but when I use it in Dashboard on BOBJ platform by passing a parameter to the Web Service, it seems no response from the Server,I made 2 test steps:
    1.Pass a value to the input parameter,I checked by ST01 in BW Server and see no records of the action, and no result return.
    2.Pass a blank to the input parameter,I checked by ST01 in BW Server and got many records,and all data be retrived.
    It seems that when I passed the parameter,the Web Service seems no response and didn't run at all. Is there anybody who can tell me how can I test the Web Service,I want to test it and input my parameter.
    Thanks very much for your quick response.
Best Regards
Martin Xie

% Wildcard selection - extract data via Query as a Web Service

Hello all,
I am using Query as a Web Service to extract data through to my Xcelsius document. I have a series of charts that display summed data according to user selections within some combo boxes.
Is there any way to send through a wildcard selection, i.e. pass a " like '%' " query string somehow through to the database?
With the query that I have created:
I have a measure value returned
I have 4 filter objects
I have selected the "Prompt" option for each
Within the Data Manager, the prompt fields are assigned to cells which reference the combo box selections
When I build the query, the selections available are many (equal to, not equal to, greater than, greater than or equal to, etc), but there is no 'like' comparison.
Alternatively, is there a way that I can pass the selected parameter values, including " like '%' " if no value is selected within a dropdown, to the original measure calculations within the universe?
I hope this makes sense, let me know if I need to clarify anything. Any help would be very much appreciated.
Cheers,
Marco

Very easy solution - select 'matches pattern' within the filter objects selection when building the query.
Don't know why I didn't try this earlier.

How to use web service in ECC 6.0

Hi.
I found some WSDL in "SDN ES Workplace".
Anybody know how to use this WSDL ?
For example, I want to use 'Query Sales Order' web service and I found WSDL in "SDN ES Workplace".
What's next step to use this web service ?
Regards, Arnold.

Hi Austin,
Link provided for mySAP ERP Enterprise Service Package ECC-SE 600, does not work. My company is SAP customer and I am SDN member.
Do I need some special login or membership to download ES packages?
I also understand that I can access the Enterprise Service from the ES Workplace (implementation) and for that I have to Apply For an Account. I applied for an account at this link https://www.sdn.sap.com/irj/sdn/esareg .
After applying for an Account should be getting an email with user Id/password OR I can use the my Service Market Place ID?
Tried entering the my service market place Id, does not work.

MDX Driver WIS 10901 Error in Query as a Web service Tool

Hello,
I'm trying to design the query as a web service to use for Xcelsius Dashboard (created connection, universe etc in Designer), but can't proceed with query definition - it's only possible to put one characteristic otherwise error WIS 10901 is triggered. Everything works fine with data based on cubes and some other queries.
Couldn't get help anywhere:

Hi Mark,
Sorry for late,
Actually the problem is in QAAWS. I can see the Universe created in QAAWS but when try to see the output bydropping the fields into the output box in QAAWS then I am getting the data base error WIS : 10901
Actually I want to know how to design the output of the query(Universe) called in QAAWS.

Multiple List Builder and Query As A Web Service Problems

Hi All,
I quickly became aware that trying to pass multiple parameters to "Query As A Web Service" from a "List Builder" object in Xcelsius was not a simple task to acheive after reading this post here :-
Query as a Web Service and In List
I followed the advice that David Brunner suggested towards the end of the thread about creating a "BI Service" by publishing a block from a Webi Rich Client report.
I then referenced the newly created "BI Service" by using it's WDSL URL through the Xcelsius Data Manager - Query As A Web Service connection.
Everything appeared to work fine (e.g. Did my selections from the last builder and got refreshed/changed figures in my Spreadsheet Table object in the Dashboard) until I realised figures in my dashboard were not reconcilling and appeared much lower than expected.
After monitoring what was happening traffic wise with "Fiddler 2" I discovered that Xcelsius was only passing the first entry in each of the selected values for the list builder even though a range of cells (e.g Month_Year!$a$2:$a$13) was specified to be passed as an input parameter to the BI Service (confirmed through viewing the Input/Output XML being sent).
I even tried specifying the multiple values in the different suggested ways that David Brunner advised such as a semi colon delimited list (e.g. Miami;Boston;Chicago) but this didn't appear to be working either.
Can anyone suggest what I may be doing wrong here? Why is only the first value being passed?
I am using Xcelsius Enterprise 2008 SP3.
Many Thanks,
Gary

Query as a web service Sorting issue

Hi All,
We have designed an existing BI query as a web service but it seems to be ignoring the Sort order of different characteristics used (as defined in Bex Query Designer).
Using the Context menu in QAAS and defining/managing the Sort is not working.
Has anyone experienced such an issue and how to handle this?
Thanks and Regards,
Bansi

Hi All,
You can try this solution. It has something to do with the universe parameter, END_SQL.
I implemented this as a work around and it solved our problem about the sorting issue with QAAWS.
Here are the steps:
1: Open the universe
2. Ope File, then Universe Parameter
3. Click the parameter tab
4. Scroll down until you see the 'END_SQL' entry. This entry is blank by default.
5. Select END_SQL
6. On the VALUE box, type: ORDER BY 1
7. This will enable the REPLACE button. Click REPLACE
8. Save the universe
9 Test a query using 2 columns and view the SQL.
You should see now the ORDER BY 1 inferred in the SQL statement.
Voila!!!!
Of course you can always add ORDER By 1,2,3 later if there's a need.
Enjoy.....

Issue using web-service with forms9i

using web-service with forms9i
Hi
I have a setup of oracle9ias release 2 on solaris machine. I have made a web-service which is deployed on nt machine on weblogic server. I have made a call from my form (forms9i) to this web-service. When i try to use that web-service after deploying my form on solaris, it initializes the web-service and performs the action successfully. Now the problem is that my form also makes a call to report server to generate a report. The problem is when i initialize the web-service and uses its function it works but after that making a call to report server will fail. Also if i make a call to report server first, it generates the report and then i make call to the web-service, then that web-service fails to run. And in both cases, the forms application stops saying session has aborted.
Why cant i make call to both the things in one session of application? What could be the reason for that? Need help urgently.

Sorry,
I didn't know that this was necessary to find a solution.

Hi AshishDatar:
For you question you want to get data from data base using web service connection. Here I can give you some suggestions
1.Write a web service to retrieve data from data base, then use Xcelsius u201Cweb service connectionu201D under u201CManage Connectionu201D section to consume the service and get the data from data base to spread sheet.
2.Xcelsius also provide you a tool to generate web service with easy way (without coding). (Suggested)
Using flynet, you can get flynet installation file under Xcelsius installation folder u201CXcelsius\Connectivity\Flynet Webservice Generatoru201D for more information about flynet please refer to

Here is also a demo on how to use web service conneciton with Xcelsius + Flynet
