SharePoint 2013 Discussion items "visibility" depending on permession for specific groups and users

Hello,
I have a blank site in SharePoint 2013 in which i activated `CommunityFeature` and i created a discussion board app which is displayed in a web part.
Now, i want to be able to change the discussion visibility ... E.g. when i click on new discussion i want to have a people picker that allows me to choose people or groups that are allowed to see and reply for that discussion...
How can this be made? can anyone help me please?

Hi,
The OOTB feature “Audience Targeting” on list item will be capable of your requirement.
“List or library items can be targeted to appear only to people who are members of a particular group or audience”.
More information about
Audience Targeting:

  • SharePoint 2013 Discussion Board lists wrong name in Reply

    Using a basic SharePoint 2013 Discussion Board with Content Approval enabled.  Because of Content Approval, all posts/replies must be approved before they are visible.  The problem is that SharePoint references the "Modified By" column
    in the Flat.aspx view when viewing a discussion thread.
    For example, let's assume we have three employees:
    Jaclyn - User who replied to main discussion thread
    Ryan - User who replied to Jaclyn's reply
    Brian - Admin w/ Approver rights to moderate comments
    In the screenshot below, Ryan clicked "Reply" on Jaclyn's comment. Once Brian approved it, SharePoint displays the note "In response to Brian's post" instead of "In response to Jaclyn's post". It seems to be referencing the
    Modified By column which updates to Brian's name once he approves it. 
    Is it possible to have SharePoint reference the correct name?  This is causing confusion in our organization since Brian is not involved in the discussion topic at all.  Thank you.

    Hi ,
    I could produce this issue based on your description.
    And I also created another Discussion Board without Content Approval, and created a new discussion, then:
    UserA replied to the main discussion thread.
    Admin replied to UserA’s reply.
    In Admin’s reply, it displayed “In response to UserA's post”.
    Administrator edited the UserA’s reply.
    UserB replied to UserA’s reply after Administrator edited.
    In UserB’s reply, it displayed “In response to Administrator's post”.
    By design, the ReplyToLink references the Modified By column of the reply when a user replys a existing reply.
    When we enable Content Approval and the approver approves the reply, by default, the approver has changed the item, and the Modified By is changed to the approver. So, for your issue, it is normal.
    Best Regards,
    Wendy

  • Unable to Customize SharePoint 2013 Discussion Board

    Hi,
    We are trying to customize SharePoint 2013 Discussion Board app and are unable to modify existing Flat, Subject, and Threaded views or create new views.  Following are the error messages we are getting:
    *** Error message when creating new views based on view types Subject, Flat, or Threaded:
    TypeError: Unable to get value of the property '0': object is null or undefined
    Note that when creating the view no options are available (only option to name and make default are available).  The view created after display of this error message does not have any Columns, Sort, Filter or
    other properties defined.  Manually defining these properties does not make the view function as desired (Flat view is not flat).
    *** Error message when editing existing default views Subject, Flat, or Threaded:
    Cannot complete this action.
    Please try again.
    Troubleshoot issues with Microsoft SharePoint Foundation.
    Note that this is nothing to troubleshoot or error number provided.  The URL shows /_vti_bin/owssvr.dll?CS=65001.  Also, the edit screen does not show any view property to change.
    Note that both ability to edit existing views and create new views work in SharePoint 2010.  This issue is with SharePoint 2013.  Please guide to resolve this.  View in other apps can be edited. 
    This issue is only with the Discussion Board app. 
    -Thanks, Maqsood.

    You will not be able to modify the default view in SharePoint 2013 i.e. Subject/Flat or threaded. However you can create a new view based on your requirement and use it.
    When you try to create new view, the fields will not be available for you to select during creation of view, instead create a view with proper name, once the view is created, go back for modifying the new view and you will have the fields available for selection.
    Note: Make sure you have mandatory CU installed on the farm.

  • Adding Attchement button inside create new discssion in SharePoint 2013 Discussion Board not from the Ribbon

    all that i want to customize create a new discussion layout by adding new attach new document but not by using Ribbon

    Hi,
    For your issue, you can customize the layout for the discussion board new form with content editor web part.
    For more information, you can refer to the blog:

    http://www.shillier.com/archive/2013/03/26/uploading-files-in-sharepoint-2013-using-csom-and-rest.aspx
    Actually in my opinion, the new file upload behavior in SharePoint 2013 is great. As we can click in the body and upload files via the ribbon INSERT tab.The
    new 2013 discussion board allow attachments to be stored in any document libraries besides the default Site Asset library.

  • Unable to get the SharePoint 2013 List names using Client object model for the input URL

    Please can you help with this issue.
    We are not able to get the SharePoint 2013 List names using Client object model for the input URL.
    What we need is to use default credentials to authenticate user to get only those list which he has access to.
    clientContext.Credentials = Net.CredentialCache.DefaultCredentials
    But in this case we are getting error saying ‘The remote server returned an error: (401) Unauthorized.’
    Instead of passing Default Credentials, if we pass the User credentials using:
    clientContext.Credentials = New Net.NetworkCredential("Administrator", "password", "contoso")
    It authenticates the user and works fine. Since we are developing a web part, it would not be possible to pass the user credentials. Also, the sample source code works perfectly fine on the SharePoint 2010 environment. We need to get the same functionality
    working for SharePoint 2013.
    We are also facing the same issue while authenticating PSI(Project Server Interface) Web services for Project Server 2013.
    Can you please let us know how we can overcome the above issue? Please let us know if you need any further information from our end on the same.
    Sample code is here: http://www.projectsolution.com/Data/Support/MS/SharePointTestApplication.zip
    Regards, PJ Mistry (Email: [email protected] | Web: http://www.projectsolution.co.uk | Blog: EPMGuy.com)

    Hi Mistry,
    I sure that CSOM will authenticate without passing the
    "clientContext.Credentials = Net.CredentialCache.DefaultCredentials" by default. It will take the current login user credentials by default. For more details about the CSOM operations refer the below link.

  • Tweak SharePoint 2013 Discussion Forum

    I have a discussion forum created in SharePoint 2013.  I want to make some minor tweaks, but searched everywhere on how to do it and changing random settings is getting me nowhere.  
    Add choice column
    I would like to add a category as a Choice column so that it shows up:
    1.    In the Subject view, ideally before the author.  E.g.
    My question about so and so
    CategoryXYZ | By Randar Puust | Latest reply by Randar Puust | About an hour ago
    2.    Editable when I add or edit a post.  I know I can do this through List Settings.  I just want to makes sure the solution to 1 does not break this.
    Default for Question
    I would like to make the Question field Yes by default.  Everything starts as an unanswered question unless they explicitly turn it off.
    Note: I am not afraid of changing code if I need to, but I've never actually done any code level customization of SharePoint.  I've barely used the SharePoint designer.  So not quite a newbie, but far from a guru.

    In terms of using the Discussion Board app, either I'm not understanding what you mean (which is very possible), or you may not realize how restricted the discussion app is 2013.  The three out of the box views (Threaded, Flat and Subject) do not allow
    any customization at all.  I can't even add columns.  I've tried to add the columns like so:
    But they do now show up in any of the views.
    I can get it to show up when the discussion item is created and when I export to Excel, but I cannot get it to show up in the threaded view.  I would include more screenshots, but this forum only allows 2 images per post, so hopefully these screenshots
    help clarify my challenge.

  • Workflow in SharePoint 2013: Update item in list

    I have a task list where anyone can post a suggestion for a blog. There is a string field for the status.
    I have a library where the author can upload the blog article when ready to send for review. Uploading the document triggers the workflow to start. This document is reviewed twice and when the author is satisfied it will go for translation and then for web
    publication.
    All of this is worked out in the workflow except for one thing: I would like to update the task list at each stage of the process to the current status. Since it can all be done programmatically, I don't need to use a "choice" field. The string
    field would be just fine. One of the things I saw in my research is that "choice" fields won't update.
    I have put a lookup field in the blog article library to correspond with the title in the task list to create a relationship.
    First of all, is it possible to do to update a task from a document library, or am I just spitting in the wind? If so, why doesn't it work?

    which specific field you want to update after task approval. Did you create a content type based on workflow task (SharePoint 2013) and associated that particular content type with your task list?
    I repeat my question - do you want to update task list after the task execution or just after assignment?
    If its just after assignment then I think its not possible OOB and if its after the execution of the task then its doable OOB since there are two variables set as task out i.e. task outcome and TaskID (guid of the current task list item) and from that TaskID
    you can lookup the task list item and update any field.

  • SharePoint 2013 Empty Item Workflows

    Dears, When querying for List Item Workflows, it always returns 0 items although there is an active workflow associated with that item. The workflow is designed using SharePoint designer 2013 and using SharePoint 2013 workflow. The code below is a sample

  • [Forum FAQ] SharePoint 2013: Extracting values from a multi-value enabled lookup column and merge values to a multi-value enabled column

    For some business requirements, users want to extract values from a multi-value enabled lookup column
    and add items to another list based on each separate value. In contrast, others want to find duplicate values in the list and merge associated values to a multi-value enabled column and then
    add items to another list based on the merged value. All of these can be achieved using SharePoint Designer 2013 Workflow.
    How to extract values from a multi-value enabled lookup column and add items to another list based
    on each separate value using SharePoint Designer 2013.
    Important actions: Loop Shape; Utility Actions
    Three scenarios
    Things to note
    Steps to create Workflow
    How to merge values to a multi-value enabled column and add item to another list based on the
    merged value using SharePoint Designer 2013.
    Important actions: Call HTTP Web Service; Build Dictionary
    Things to note
    Steps to create Workflow
    How to
    extract values from a multi-value enabled lookup column and
    add items to another list based on each separate value using SharePoint Designer 2013.
    For example, they have three lists as below. They want to
    extract values from the Destinations column
    in Lookup2 and add items to Lookup3 based on each country and set Title to current item: ID.
    Lookup1:
    Title (Single line of text)
    Lookup2:
    Title (Single line of text), Destinations (Lookup; Get information from: Lookup1 in Title column).\
    Lookup3:
    Title (Single line of text), Country (Single line of text).
    Important action
    1. Loop Shape: SharePoint Designer 2013 support two types of loops: loop n times and loop with condition.
    Loops must also conform to the following rules:
    Loops must be within a stage, and stages cannot be within a loop.
    Steps may be within a loop.
    Loops may have only one entry and one exit point.
    2. Utility Actions: It contains many actions, such as ‘Extract Substring from Index of String’ and ‘Find substring in String’.
    Three scenarios
    We need to loop through the string returned from the look up column and look for commas. There are three
    scenarios:
    1.  No comma but string is non-empty so there is only one country.
    2.  At least one comma so there is at least two or more countries to loop.
    3.  In the loop we have consumed all the commas so we have found the last country. 
    Things to note
    There are two things to note:
    1. "Find string in string (output to Variable:index)"  will return -1 if doesn't find
    the searched for string.
    2. In the opening statement "Set Variable: Countries to Current Item:Destinations" set the return
    field as  "Lookup Values, Comma Delimited".
    Steps to create Workflow
    Create a custom list named Lookup1.
    Create a custom list named Lookup2, add column: Destinations (Lookup; Get information from: Lookup1 in Title column).
    Create a custom list named Lookup3, add column: Country (Single line of text).
    Create a workflow associated to Lookup2.
    Add conditions and actions:
    Start the workflow automatically when an item is created.
    Add item to Lookup2, then workflow will be started automatically and create multiple items to lookup3.
    See the below in workflow History List:
    How to merge values to a multi-value enabled column and add item to another list based on the
    merged value using SharePoint Designer 2013
    For example, they have three lists as below. They want to find duplicate values in the Title column in
    Lookup3 and merge country column to a multi-value enabled column and then add item to lookup2 and set the Title to Current Item: Title.
    Lookup1:
    Title (Single line of text)
    Lookup3:
    Title (Single line of text), Country (Single line of text).
    Lookup2:
    Title (Single line of text), Test (Single line of text).
    Important actions
    "Call HTTP Web Service"
    action: In SharePoint 2013 workflows, we can call a web service using a new action introduced in SharePoint 2013 named Call HTTP Web Service. This action
    is flexible and allows you to make simple calls to a web service easily, or, if needed, you can create more complex calls using HTTP verbs as well as allowing you to add HTTP headers.
    “Build Dictionary"
    action:
    The Dictionary variable type is a new variable type in the SharePoint 2013 Workflow.
    The following are the three actions specifically designed for the Dictionary variable type: Build Dictionary, Count Items in a Dictionary and Get an Item from a Dictionary.
    The "Call HTTP Web Service" workflow action would be useless without the new "Dictionary" workflow action.
    Things to note
    The
    HTTP URI is set to https://sitename/_api/web/lists/GetByTitle('listname')/items?$orderby=Id%20desc and the HTTP method is set to “GET”. Then the list will be sort by Id in descending order.
    Use Get
    d/results(0)/Id form
    Variable: ResponseContent (Output to
    Variable: maxid) to get the Max ID.
    Use Set
    Variable: minid to Current List:ID to get the Min ID.
    Use Copy from
    Variable: destianation , starting at
    1 (Output to
    Variable: destianation) to remove the space.
    Steps to create Workflow
    Create a custom list named Lookup1.
    Create a custom list named Lookup2, add column: Test (Single line of text).
    Create a custom list named Lookup3, add column: Country (Single line of text).
    Create a workflow associated to Lookup3.
    Add a new "Build Dictionary" action
    to define the http request header:
    Add a Call HTTP Web Serviceaction, click on
    this and paste your http request.
    To associate the
    RequestHeader variable, select the Call action property,
    set the
    RequestHeaders property to
    RequestHeader:
    In the Call action, click on
    response and associate the response to a new
    variable: ResponseContent (of type Dictionary).
    After the Call action add Get item from Dictionary action to get the Max ID.
    Add Set Workflow Variable action to get the Min ID.
    Add Loop Shape (Loop with Condition) to get all the duplicate titles and integrate them to a string.
    Create item in Lookup2.
    The final Stage should look like this:
    Start the workflow automatically when an item is created.
    Add item to Lookup3, then workflow will be started automatically and create item to lookup2.
    See the below in workflow History List:

    GREAT info, but it may be helpful to note that when replacing a portion of the variable "Countries" with a whitespace character, you may cause the workflow to fail in a few specific cases (certain lookup fields will not accept this and will automatically
    cancel).  I only found this out when recreating your workflow on a similar, but much more complex list set.  
    To resolve this issue, I used another utility action (Extract Substring from Index of List) to clear out the whitespace.  I configured it as "Copy from
    Variable: Countries, starting at
    1 (Output to Variable: Countries), which takes care of this issue in those few cases.
    Otherwise, WOW!  AWESOME JOB!  Thanks!  :)

  • Sharepoint 2013: Problem / Error when creating Variation Hierarchy for French and German Languages from Variation root EN

    Hi,
    I have a website with English and Arabic Language Packs installed. I have the corresponding Variation heirachies created and the whole site collection is published.
    Recently the client asked for french and german languages to be accomodated as well. So I followed the same approach I did for English and arabic (installed the language packs) for foundation, ran ocnfiguration wizard, installed server language pack &
    ran configuration wizard.
    But after creating the variation label, when i try to create the variation heirarchy, I am getting the following error.
    "Unknown failure when creating a variation of page http://server:port/en/pages/default.aspx in label /fr/Pages/default.aspx.
    The Variations Create Hierarchies job failed with the following error message&  Unknown failure when creating a variation of site
    http://server:port/en in label fr."
    Am not sure what is going wrong. Appreciate a feedback.

    Hi,
    According to your description, my understanding is that the error occurred when you created the Variation Hierarchy for French and German Languages from Variation root EN.
    I recommend to check the Resources folder located at C:\Program Files\Common Files\microsoft shared\Web Server Extensions\15 to see if the file core.fr-FR.resx exists in the folder.

  • Mass delete of PO item texts for specific PO and SA

    Hi All,
    I have thousands open PO's and SA's coming in during conversion in SAP system. For many of them we have material specifications and drawing number coming in from legacy and we populate them using standard BAPI create function module.
    On the other hand we also have a BADI activated ME_PROCESS_PO_CUST which populates the PO item text 'spec details' from material master CLASSIFICATION and drawing number from BASIC DATA2.
    We have a logic implemented saying if legacy file has a value in Material Specification it will not trigger the BADI, if the value is NULL it will trigger the BADI and fetch the data from Material Master.
    But now we want to have the material specifications coming in from legacy as it is. If it has a value it will populate, if it is blank it will leave it blank.
    My question is without a change around the BADI and PO create function module what are the ways to delete the item texts from the PO's and SA's for which legacy value is NULL. The deletion will be only for specific PO's, say out of 10000 PO line items posted in the system I want to delete Material Spec for 6000 of them. Appreciate your help in advance.

    you have to write your selection  logic in a small ABAP and then call the funcion module DELETE_TEXT

  • Sharepoint 2013 discussion board item view (flat.aspx) throws js error after being migrated from moss 2007

    After preforming a migration from moss 2007 to 2013 on-prem we have noticed that html tags are showing up in the discussion board posts.  I have tracked the problem down to the flat.aspx page throwing a js error. 
    'SPAnimationUtility' is undefined - coming from the sp.ui.discussions.js file
    this is what I see on the page: 
    The reply and edit buttons function fine.  Its just that the html is exposed. 
    Anyone seen this before or have a clue as to how to solve?  
    Thanks,
    -Alex

    As I remember there are a couple managed properties (metadata) that are used by the views that don't get created when you migrate a discussion board from a previous version.  I don't remember the specific properties, but take a look at a new discussion
    board in 2013 and compare the properties in the views and you will find them.

  • Sharepoint 2013 Discussion Board Web Part, Subject line link on Home Page does not link to the list view

    I am by no means a SharePoint developer, but I really wanted to customize the discussion board for my site - so I found this link: http://www.codeproject.com/Articles/733164/How-to-create-HelpDesk-on-SharePoint-Online
    I added the columns, like the article said, and then completed the section "Modification of the discussion board views".  I skipped the workflow stuff because while I think it would be useful I wanted to make sure I could get
    the actual customization of the discussion board to work first. 
    My Problem (Just to preface - I followed the above instructions, including disabling the Minimal Download Strategy):
    When I clicked into my discussion board list, I was able to get it to look and function as described for both the subject and flat views. However, when I click on the Subject, from the Discussion Board Web Part on my Home Page, it does not redirect into the
    Discussion Board List Flat View.  Instead, it tries to open the root folder from the Home Page while still using the subject view.  The outcome being an empty discussion board on the Home Page.
    So I decided to create a whole new discussion board to see if that one would work, when I inserted a new Discussion Board Web Part into the Home Page, newly created from the app menu, it used the same custom JS file(plumTickets), even though I never linked
    the discussion board to the JS file. Of course when I went into the newly created Discussion Board list it opened as it does OOTB.
    I am so close it having this work like I have been envisioning.  I just need users to be able to click on a discussion subject from the Home Page and be redirected to the list view of the parent folder (I think that is the correct terminology,
    but it may not be) so they would be able to see any replies and be able to reply.  Please Help Me!!!
    I truly appreciate any help you are able to provide, thank you!

    I figured it out. I was using ?FilterField1=fieldname&FilterValue1=value on the URL to the page to pick out one project number. The web part I was trying to add was for a list that did not have that particular fieldname. I didn't realize that would matter
    since I was using the Connections -> Get Filter Values From to get my filter values from the main web part, which does have that fieldname.
    I added a field with that fieldname to the other list and set a workflow to copy the lookup value of the project number lookup field into the new field. Now all is working fine.  Sorry for the wild geese in my original question.

  • SharePoint 2013 - In document library, an unexpected error has occurred when a user clicks on ellipsis then "EDIT"

    Just as the title infers, I have a user who is experiencing an unexpected error when he clicks on "EDIT" after clicking on the ellipsis. Document in the Document library is an MS Word file.

    Hi,
    According to your post, my understanding is that an unexpected error has occurred when a user clicks on ellipsis then "EDIT".
    Please make sure he has the edit permission.
    Please make sure the Office 2013 is installed correctly on his computer.
    In addition, I recommend to use another brower to check whether it works.
    If so and the error message persists, please check the SharePoint ULS log to find more information about this error, the ULS
    log file is in the location: C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\LOGS
