Download/Upload Multi-valued property using Code

We are developing program that will download document properties from one Portal Server and upload document properties to another server.
Can someone provide a code snipplet on how to deal with multi-valued property for this download/upload requirement.
1. How do we download property values for Multi-valued properties for document.
2. How do we upload property values for Multi-valued properties for document.

We were able to do this. This bug is fixed by SAP in 7.0 ICE.

Setting multi-value parameters using ReportExecutionService

Does anyone know how to set multi-value parameters using ReportExecutionService in C#?
If I have

How to create a multi value property

Hello,
I've defined a new property to use with the FAQ form, and set it to a multi value enabled (Multi-Valued checkbox on, Property Renderer set to multivalued).
I've added a new Combo Box object to the form using Form Builder, and assign the property to it.
However, I'm able to choose only one value while creating a new FAQ.
What should I do in order to make it a multi value selection box (without programming) ?
Thanks
Eli

Hi,
You have to use the PortalApp.xml file
In that file you have to create the properties and can have n options, it will not require programming.
<?xml version="1.0" encoding="utf-8"?>

Multi valued property metadata modifying using Portal Drive

Hi All,
We are analyzing Portal Drive tool for KM.
We have multivalued properties for files say geo:USA, APAC etc... Once we give value to geo property by being online in portal drive it is not reflectiong in Portal.
We are not able to view geo value in property through network mapped drive even if we maintain value in KM manually.
Please guide.

Retrieving empty values from multi value string in user profile custom properties

Hi,
I created a webpart to save and retrieve data from custom properties. I use the code below to get the stored data:
for (int i = 0; i < profile[property].Count; i++)
Item = profile[property][i] == null ? string.Empty : profile[property][i].ToString();
list.Add(Regex.Split(Item, @"\,\#"));
Nothinig special about it.
In my development environment, it works fine. The problem is in my UAT environment. I'm facing an issue that i hope someone has been through. When the custom property is a multi value string type, it returns a empty string. I tested with HTML and single
value fields and it works fine.
Independently of the field type, it saves the data all right.
Can anyone help me?
Thanks!!

Thanks, Chitvan Jain.
I did as you suggested, but nothing changed. The problem is that profile[propname] comes already blank when using multi value property, even if there is data to be retrieved.
One funny thing is that, somehow the code manages to count the number of values there is in the property. Only the data is missing. We can see the exact number of column, cause i check if there's the right number of data, if there isn't, i add up a empty
string on the grid cell, but only for viewing. The empty string is not stored in the property.

Insert Value(s) in Lookup Flat Multi-valued Table with Java API

I've been looking in MDM Java API Library Reference Guide, MDM SP4 API JavaDoc, and SDN Forums for information on how to Insert/Update different values in a field in the Main Table of a given repository that belongs to a Lookup Flat Multi-valued Table using the Java API with no success.
I also haven't been successful in adding this values in the same way that I'll add a single value, using the MDM Java API, in a single-value Lookup Table (a2iFields.Add(new A2iField(FIELD_CODE,FIELD_VALUE)) for each value I want to add, like for example:
a2iFields.Add(new A2iField("Country","USA")
a2iFields.Add(new A2iField("Country","Mexico")
a2iFields.Add(new A2iField("Country","Germany")
Can anybody point me to the correct documentation that I need to read to fulfill this task? Or, even better, if someone can post a piece of code, I'll be more thankful.
Thanks for your help.

HI,
little code example, where you add existing lookup values based on there record id:
     int USA = 1;
                    int GERMANY = 2;
                    A2iValueArray countryArray = new A2iValueArray();
                    countryArray.Add(new Value(USA));
                    countryArray.Add(new Value(GERMANY));
                    A2iFields record = new A2iFields();
                    record.Add(new A2iField("Country", new Value(countryArray)));
Please reward points if helpful.

Handling multi-value parameters in VS 2005 / Crystal 2008

In my program I am trying to handle a multi-value parameter using the following code, passing it an array of type string with the values that the user selected, but using the following code returns a 'Missing parameter values' error.
    For Each crParameterFieldDefinition In crParameterFieldDefinitions
        If Not crParameterFieldDefinition.IsLinked And crParameterFieldDefinition.ReportName = "" Then
            crParameterValues = crParameterFieldDefinition.CurrentValues
            crParameterDiscreteValue = New ParameterDiscreteValue
            If crParameterFieldDefinition.EnableAllowMultipleValue Then
                Dim j As Integer
                Dim x() As String = Session("FieldDef")
                For j = 0 To x.GetUpperBound(0) - 1
                    crParameterDiscreteValue.Value = x(j)
                    crParameterFieldDefinition.CurrentValues.Add(crParameterDiscreteValue)
                Next
            End If
            Session.Remove("FieldDef")
            i = i + 1
        End If
    Next
I have also tried loading the values into a ParameterValues object and then using ParameterFieldDefinition.ApplyCurrentValues on it, which has been working fine for all of my single value inputs, but using that throws an error about a type mismatch. Any help at all would be appreciated.

There are a few samples to look at here:

Upload Profile Values

Hi Folks,
I would like to know how to upload profile values in SAP.
In our current project due to time zone problem half of the profile values are stored in one valueday and the rest of the values are stored for the next valueday.
Thanks,
Imran

Hi Imran,
You can upload profile values through transaction code EEDM01.
However, through the above transaction code you can only upload on a one to one basis and not mass.
If you want to perform a mass upload of profile values you need to develop a customise program using the FM BAPI_ISUPROFILE_UPLOAD.
Hope it helps...
Thanks,
Amlan

Multi-Valued Properties in XML Forms

Hello,
Can anyone tell me how to select multiple values for multi-valued properties in an XML Forms. It seems that the combo box only allows you to select one value.
Thanks,
Chris.

Hi Chris,
nice to hear, that you're implementing my way of solving this multi value issue. And much nicer to hear, that it seems to work for you, too!
You can not write back your multi value properties from XML form. Thats for sure. You can think of:
1. Synchronize the value of your text field property with the value of the multi value propery whenever you store the document. This could be done using the event "property set".
<a href="https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/5d0ab890-0201-0010-849d-98d70bd1d5f0">See: KM Events</a>
2. Overwrite the content of your multi value property at runtime, depending on the value of the single value property which holds the csv. Do this by using a Repository Filter. <a href="https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/70ee3a57-0701-0010-3e9a-ddae7e4e0521">See: RepositoryFilter</a>
3. Forget about the multi value property and make the text field property indexable. This should work, too.
All three options should work!

Multi value refiners -- Remove Other Value

While using Multi value refiners (using check boxes) is there any way we can remove Other Value refiner.
Thanks in advance.

Hi,
You can write some CSS to hide this control, or use Javascript to remove it.
If you are looking for a more standard solution, you can create a custom refiner control template.

How can I get all the values of a String array profile property using javascript?

I am trying to build functionality into our site that records all products added to the basket against a user's profile.
I have so far been able to store the product codes against the profile as a property using Ajax:
       var dataString = ":formid=addProduct&:formstart=/apps/thread/templates/page_product/jcr:content/par/produc t/formstart&:redirect=/content/thread/en/user/cart.html&productId=151515:profile="+profile ;
                     $.ajax({
            type: "POST",
            url: "/content/women/evening/dresses/l-k-bennett-davinadress.html",
            data: dataString,
            success: function(data) {
In this example I have hardcoded a product ID of 151515.
In order to save the property as a multi string field you simply replace &productId=151515 with &productId=151515&productId=131313&productId=141414 or as many extra values as you want to build into that string. This stores a productId property against a user profile.
The issue comes from calling that data back. Using var value = CQ_Analytics.ProfileDataMgr.getProperty("productId") I can get the first value of this array (or the single value if only one is stored).
However there does not seem to be a way to get any of the other stored values in the array using getProperty. Does anyone know how I can achieve this?

Hi,
Don't think that's possible. Even if it were, you wouldn't be able to use/display BOOLEAN type in SQL.
If you just aim to see what they are, you could do something like this
select text
from all_source
where owner = 'SYS'
   and name = 'DBMS_DB_VERSION'
   and type = 'PACKAGE';Or even
select dbms_metadata.get_ddl('PACKAGE', 'DBMS_DB_VERSION', 'SYS') from dual;My version is:
SQL> select * from v$version where rownum = 1;

Passing value to multi value parameter from SSIS using Report server webservice

Hi
I am triggering SSRS report from SSIS(Script task). I am passing parameter values from SSIS package.
So far working fine. Now, I have a report which has 2 parameters. One is single value parameter and the other is multi value parameter.
No issue assigning value to single value parameter. But how can I pass multi value to multi value parameter?
My code as below
ReportExecutionService rs = new ReportExecutionService()
rs.Credentials = System.Net.CredentialCache.DefaultCredentials;
rs.Url = _webserviceURL;
rs.LoadReport(_reportPath, null);
ParameterValue[] paramval = new ParameterValue[2];
                        paramval[0] = new ParameterValue();
                        paramval[0].Name = "CountryCode";
                        paramval[0].Value = _countryNames;
                        **paramval[1] = new ParameterValue();
                        paramval[1].Name = "BusinessCode";
                        paramval[1].Value = _businessCode;****
                        rs.SetExecutionParameters(paramval, "en-us");
I am not sure how to pass value to BusinessCode(Multi value parameter)

Hi Rajkm,
In order to pass a multi-value parameter through the Reporting Services Web services, you need to define the same numbers of ParameterValue objects as the number of the values of the multi-value parameter being past into the report. The Name property
of these ParameterValue objects must be specified same to the parameter name.
I found a good FAQ article for this scenario:
How do I pass a multi-value parameter into a report with Reporting Services Web service API?:
http://blogs.msdn.com/b/sqlforum/archive/2010/12/21/faq-how-do-i-pass-a-multi-value-parameter-into-a-report-with-sql-server-reporting-services-ssrs-web-services-api.aspx

I have checked MP ; it has all the values but some how the template not called. When I removed this condition it working and when choose other MP other then Multi valued. It is working as expected.
Please let me know if i miss something here.
PS: I have checked each option from the Query drop down like "Equals any of" and "Contains any of" not working in case of multi value attribute. Please help.

ECC6.0 code download/upload with unicode

Hi, we have a need for on-going parallel code maintenance of 2 separate development instances. In end effect we need to manually synchronize two development instances for a period of time. We have before in the past used custom programs and some of the standard SAP utilities provided. However I'd be surprised if there isn't a more comprehensive utility supplied by SAP by now for this purpose. By now I mean with release ECC6.0 with unicode active. Does anyone out there know of a utility that can download any program(WebDynpro, BSP, R/3 dynpro, report, program, function module, class, etc with all relevant textpools and documentation) to a file so that it can be uploaded in its entirety without great effort? We currently have a custom program which downloads/uploads ABAP source and text but it only works with standard executable r/3 programs.
Thanks in advance,
Kevin

Useful Code of the Day: Multipart Form File Upload

So, you want to upload files to your web server, do ya? Well, I've seen this topic posted a few times in the last month or so and many of the response I've seen here haven't included definitive answers. Of course, the actual problems vary, but ultimately, a bunch of people want to do file upload from an applet or application to an existing file upload script (CGI, PHP, JSP, etc.) on a web server. And invariably, there are problems with formatting the HTTP request to get things working.
Well, I had a need to do the same thing. I realize there are other solutions out there, such as some sample code that comes with Jakarta Commons Upload. But since we all like reusable code, and we also all seem to like reinventing wheels, here's my go at it: MultiPartFormOutputStream!
MultiPartFormOutputStream is a specialized OutputStream-like class. You create your URLConnection to the server (a static method included can do this for a URL for you, as some of the settings, doInput and doOutput specifically, seem to confuse people). Then get the OutputStream from it and create a boundary string (a static method to create one is provided as well) and pass them to the constructor. Now you have a MultiPartFormOutputStream which you can use to write form fields like text fields, checkboxes, etc., as well as write file data (from Files, InputStreams or raw bytes).
There are some convenience methods for writing primative type values as well as strings, but any higher level objects (aside from Files or InputStreams) aren't supported. (You can always serialize and pass the raw bytes.)
Sample usage code is below. Also, any recommendations for improvement are requested. The code was tested with the Jakarta Struts.

I have a weird problem here. I'm using the Java POST (slightly altered for my purposes) mechanism but the receiving script doesn't receive any form variables (neither files nor regular form fields). If I try using the same receiving script with a regular upload form, it works. Because I've been pulling my hair out, I even went so far as to analyze the ip-packets. I can see that the file is actually sent through the Java POST mecahnism. Anybody any ideas. Here's the ip-packet of the failing upload:
----- Hypertext Transfer Protocol -----
HTTP: POST /fotoxs/upload.cfm HTTP/1.1
HTTP: Connection: Keep-Alive
HTTP: Content-Type: multipart/form-data; boundary=-----------------------------fb2649be18
HTTP: User-Agent: Mozilla/4.7 [en] (WinNT; U)

The one that works (from the regular post) is as follows:

One detail worth mentioning is that I don't read a file from harddisk, I'm streaming it directly to the connection outputstream from an image compression utility. But I can see the data in the ip-packets, and even if that somehow didn't work right, it doesn't explaing the fact that the receiving scripts reports no form fields whatsoever.
Thanks,
Marc
