How to get distinct values of sharepoint column using SSRS: paramter Greyed out

Posted By:      Posted Date: September 30, 2010    Points: 0   Category :Sql Server
 

I'm referring to a previous thread: How to get distinct values of SharePoint column using SSRS.  I followed all the steps as set out but when I view my report, the parameter is greyed out.  I then downloaded the example report of Jin Chen.  In that report, he suggests a blank parameter label for the main parameter, as well as, a default value for the hidden parameter (which is different from the initial thread posted).  When I change my report accordingly, I get an error: An error occurred during local report processing. MainParameter.  Anyone with suggestions?

Hi,

    I have integrated sharepoint list data to SQL Server reporting services. I am using the below to query sharepoint list data using sql reporting services.

<Query>
   <SoapAction>http://schemas.microsoft.com/sharepoint/soap/GetListItems</SoapAction>
   <Method Namespace="http://schemas.microsoft.com/sharepoint/soap/" Name="GetListItems">
      <Parameters>
         <Parameter Name="listName">
            <DefaultValue>{GUID of list}</DefaultValue>
         </Parameter>
         <Parameter Name="viewName">
            <DefaultValue>{GUID of listview}</DefaultValue>
         </Parameter>
         <Parameter Name="rowLimit">
            <DefaultValue>9999</DefaultValue>
         </Parameter>           
      </Parameters>
   </Method>  
<ElementPath IgnoreNamespaces="True">*</ElementPath>
</Query>

By using this query, I am getting a dataset which includes all the columns of sharepoint list. Among these columns, I wanted to display only 2 columns (i.e Region and Sales type) using chart. I have created a Region parameter but when I click

How to get sum of a column from sharepoint list into SSRS(2005)

  
Hi, I have a about 100 columns created for survey questions. I need to get the sum of each column into SSRS. Can it be done in dataset instead of adding the aggregate expression in the footer of ssrs table. Some research that I have done so far.......Under the sharepoint list there is an option for Total for each columns. I can select the sum option and it appears in the list, but how can I access this sum in SSRS.

How to sum multiple values in column in SSRS 2008

  

Hi all,

Stuck on a reporting services issue when it comes to summing multiple values from a column.

I have created a table in SSRS (VS 2008) where one of the cells computes its value from summing all the values in column X. All the values in column X are expressions (Parameters!pABC.Value * Fields!DEF.Value). 

How do I write an expression in cell A that will sum all the values that result in column X when the report is run? Do I need to write custom code for this?

Number of rows/Values in column X is dynamic.

All help much appreciated! Thank you!

Duplicate column names from forms in SharePoint lists

  

 

I'm in the process of migrating from a WSS 2 site to WSS 3/MOSS. On the old site I used an Infopath 2003 form for absence requests. During the migration I now use Infopath 2007. There wasn't any problem initially when the form was stored with the SharePoint form library. However, when I published the form as a content type from Infopath 2007 and then added that content type to the form library, there are two columns for each piece of data from the form. (One from the content type and one from the form list.) I relinked each old form (list content type) to the new AbsenceRequest content type and removed the original one from the list. However, the duplicate column names are still there. Since they came from the Infopath form, they are not editable or deletable from the SharePoint list management interface. The duplicate column names make it tough to build views since it isn't apparent which column to use in the form building UI. It can be determined form the overview display, but it is very cumbersome.

 

Does anyone know a way to get rid of the old, absolute, columns?

SSRS 2008 R2 and sharepoint 2007 report builder problems

  

I upgraded our enterprise sql server 2008 to sql server 2008 r2 last weekend.  Along with this i installed the report builder 3.0 on the servers as well and the updated ssrs add in for sharepoint.  The upgrade went fine, no errors that i could find.  The problem is now when i go to a library that has the report builder content type enabled and click report builder report under new it does not load report builder 3.0.

I updated the custom report builder url in central administration from /_vti_bin/ReportBuilder/ReportBuilder_2_0_0_0.application to /_vti_bin/ReportBuilder/ReportBuilder_3_0_0_0.application

however when i do click the new report builder report it kicks me over to http://company.com/ReportServer_MossEnt  which itemizes out each individual sharepoint site in the farm.

Is the integration of ssrs 2008 r2, sharepoint 2007 and report builder 3.0 work?  did i install the wrong version of the report builder add in?  The above is the only problem i am having now.

all servers are server 2008, 64 bit and moss 2007 enterprise with sp2 & april 2010 cu

Configure BDC column to have multiple values selected

  

How do I Configure BDC column to have multiple values selected and make multiple entities data available in the same column.  Currently it supports only single value for an item.  This requirement is crucial need some solution immediately.


BDC Column with Ability to Select Multiple Values

  

Use Case:

We are creating a storage location for technical product articles. These will be SharePoint publishing pages. Each page will have metadata assigned to it to make it searchable by properties. The possible values for one of the columns (Part Number) could potentially be sourced by our ERP system. I'd like to do this to eliminate the possibility of free-text entry errors, but there are probably over 10,000 parts so a drop-down list isn't feasible.

 

Ideal Situation:

The end user enters the part number and clicks a button to verify it against a BDC entry from our ERP system. If they weren't sure on the part number they needed, they could do a lookup from that metadata entry screen. They'd need to have the option to add multiple part numbers as one technical product article could reference multiple part numbers.

 

Question:

Is BDC an option for all of this or am I looking at a custom metadata solution? I thought I heard along the way that BDC only supported one value choice, but I couldn't find a verification for that in the forums.

 

Thanks.

wss2.0 update/delete/hide lookup column that does not display any values

  

Hi All,

I have a document library that contains a Category column that is a lookup field. This is a default column that is a required field when uploading documents to the document library. The Category column is empty and I am unable to amend, hide, make it not required or delete it.

I have gone to Modify settings and columns -> clicked on the Category field to edit, but there is no option to amend the content or delete it. I am only able to amend the Column name and Description.

Since then, I have amended the column name to eg. Category1 and created a new Category field as a lookup and linked it to the correct list.

The problem I am facing now, is that I cannot hide, delete or make the Category1 (old Category) field NOT required. Either I would like to update the original field to display the correct values or alternately hide, delete or make the column not required.

Please help.
