Linked Lists by Lookup/ Retrieve value in workflow

I have two lists linked by a look-up.
Genere List has title of genres and a Radio button named Active selectable values Yes/No.
Track list has a lookup field to Genere List and displays the title of the Genere.
I have a List Workflow on Track  that starts on new track item. At some point in the workflow, I want to get the Active field from the Genere of the current track.I have been trying but doesn't work and my workflow just get stuck on that stage.
I am not finding anywhere how to do this step by step to identify what I am doing wrong. Or perhaps I'm not using the right search queries/terminology

Hi Stephan,
While creating Lookup column in Track list to show Genere title from Genere list, you have the option to select 'Add a column to show each of these additional fields:' You can select your column 'Active' there. 
When you select Genere for a new Track, it also pulls the value for Active field. You should be able to easily access Active field through Designer workflow running for a new Track item.
Thanks.

  • Addition in a linked list

    Hi,
    I want to add numbers in a linked list. For example when i pass in the string 123456789, i reverse it so that it appears as 987654321 in the linked list. If i add this to the string 954 which appears as 459 in the linked list, i am supposed to get 123457743 but i get 1743. How do i rectify this from my code.

  • Workflow will lookup a value from one list and update to second list , in second list wants to calculate using that lookup value

    Hi,
    I'm Palanivel , In my site collection , I have 2 lists , In 1st list , i have id,name and Total Annual leave . In 2nd List i have ID,No of Days(taking leave),Balance Annual Leave.
    My first task is,In List 2, get the value from list 1.total annual leave to list 2.balance annual leave. Next , i do some calculation ,that is (balance annual leave - no of days = balance annual leave) .
    Now my updates working correctly . and the calculation also working but when next time applying leave , again the update process working , so balance annual leave becomes my total annual leave .
    my question is how to do a update process only first time , next time only calculation task has to be performed .
    how to do 2 task in a single workflow , the 1st task must run only one time .
    please help ....
    thanks in advance

    Anyway-hopefully I am not talking to myself here.
    The database i am using is Oracle 10 g version 1 and using vb2005 express.
    As mentioned above the problem is the value of the parameter does not go into the query statement.
    The same logic with changes made works for other major databases. So I do not think it is the logic.
    Any suggestions?

  • Reading values from lookup columns through custom workflow in SharePoint 2013

    We are able to read the values of text, number columns through custom workflow (via coding) in SharePoint 2013. However, we are not able to read values from lookup columns. So, request anyone to provide help on this.
    Thanks & regards,
    Aditya

    Hi,
    According to your post, my understanding is that you want to read values from lookup columns through custom workflow in SharePoint 2013.
    Since the workflow just doesn't get lookup fields, let's give it something static to work with instead. If we can capture the ID of the lookup field and store that as a static value in our list, the workflow can happily use that to look up our related.
    For more information, you can refer to:
    SharePoint 2013 Workflows and Lookup Columns

  • How to set a list form field data value that is linked to another document library's data when the link gets broken!!??

    In summary, I have created 3 document libraries and one issues list in a site collection.
    The issues list has a form that has mainly been created in SharePoint 2010 but tweaked in InfoPath 2007 and one of the fields links to the title of a document in the first document library (so an issue can be linked/referenced to a particular document).
    This all works great until I want to move a document (using the workflow that I built) from document library 1, to document library 2 or 3 as this is what I've set up to move documents through the business process we are taking it through.
    When this happens, the link between the issue that was raised originally against the document is broken and therefore you can no longer tell which document the issue is linked with.
    Does anyone know a way of 'setting' the field that is linked to data in another document library on original selection/creation of the issue, so that when the link is broken the original data remains.
    Any ideas welcome as I am stomped!!! 
    Cheers!!
    Louis Maxwell

    
    Hi  Louis,
    According to your description, my understanding is that you want to keep the link field of the issue list working after moving the linked document.
    Whether the link field  is a lookup column or not ?
    If so, due to the information source of  lookup column cannot be changed, you need to add other lookup fields for document library 2 and document library 3. Just one lookup column corresponds one document
    library. Then you can update the lookup column in the workflow when move the linked document. Such as when a document is moved to document library 2, you need to clear the lookup1 field (corresponding document library 1) and update the lookup2 field (corresponding
    document library 2).
    For updating the lookup column, you can refer to the following actions:

    Which version are you using?  Can you please try and narrow down to the offending field?  You can do this by limiting the fields you provide to ResultDefinition.

    Initially I had the above, it return only 1 that was the reason for puting the loop.You don't seem to understand recursion or variable scope.
    int large = 0;large is a different variable inside each instance of the method.
    So when you get back up to the value 1 from the recursive calls its just comparing 1 to 0
    Here's a solution...
         public static int Largest(Node top){
              if(top.next != null){
                   if(Largest(top.next) > top.num)
                        return Largest(top.next);}

  • Values of data  in a linked-list

    hello.
    i declare a small linked list of elemets (about 10), everything is fine and dandy but i need to assign an int value to every one of those elements as a counter whenever a certain action is performed on the element in the list.
    LinkedList mylist = new Linkedlist();
    int value=0;
    //i need to assign a unique int value to every element in the list as a counter to keep track of how many times [whatever element] is accessed, moved around, ect.
    is this possible?

    If your linked list contains a specific type of object, add a counter to it. This may mean extending whatever the class the element is.
    If you want to do theis generically, you are probably going to have to extend LinkedList and inside that class encapsulate another collection (maybe a linked list). The encapsulated collection will contain the set of counters. You will have to override all of LinkedLists methods so that you can maintain the counters.

    you can use cascading LOV for that, i which the other LOV field will be changing depending upon the selection of other value(which is in LOV).

  • Append Lookup Column Values using SharePoint Designer Workflow

    Hi all,
    I can set the value of a lookup column using number;#itemname (ex. 1;#MyValue), but I need to add a value to a lookup column that has existing values. I have tried setting the lookup column to the current value plus the new value, but it fails. Please assist.
    Regards,
    Kelly
    Personal Blog: http://thebitsthatbyte.com

    This would fail because when using a lookup, that value must exist. The lookup creates a reference and if it can't find the reference in the list it's looking up to, it will fail. If you want to set it to something that is not in that list, then you'd
    either need to add it to the list first (run a loop through the list and check to see if it's there, Yes=set the field, No=create new item in list and then set field) or use a single line of text field.

  • Changing data in a linked list object.

    hi,
    i'm still pretty new to java, so bear with me if i am making stupid mistakes, heh.
    i'm having trouble with changing data in an object stored in a singly-linked list. i've created a class that will store polynomials in sorted order (descending) in a singly-linked list. each linked list is one polynomial, and each node references to a polynomial object that stores two ints: the coefficient and the exponent of that term.
    i'm having trouble when it comes to 'collecting like terms,' though. here's a rough skeleton of my code:
    public class Polynomial
    private LinkedList polynoList;
    private LinkedListItr Itr;
    private int coeff;
    private int exponent;
    public Polynomial()
    zeroPolynomial();
    } // this constructor sets up an empty linked list
    public Polynomial( int c, int e )
    coeff = c;
    exponent = e;
    } // this creates a Polynomial object storing the two ints
    public void zeroPolynomial()
    polynoList = new LinkedList();
    theItr = polynoList.zeroth();
    } // this method creates the empty linked list and sets the
    //iterator on the zeroth node.
    //various other methods are here, not relevant to my post
    //this next method is the one i am having trouble with.
    //it takes two ints as parameters, the coefficient
    //and the exponent.
    public void insertTerm( int c, int e )
    //...i have a few if/then statements here
    //so that the terms can be inserted in descending order.
    LinkedListItr tester = polynoList.first();
    //the 'tester' iterator is set on the first node
    //this following if statement retrieves the exponent
    //in the current node by casting the information
    //retrieved from the LinkedList retrieve() method
    //into Polynomial, then compares it to the current
    //exponent. if they are equal, i want to add the
    //coefficients.
    if( e == ((Polynomial)tester.retrieve()).getExp() )
    this.coeff = ((Polynomial)tester.retrieve()).getCoeff() + c;
    //a main method goes here wherein the user can insert
    //terms, print the polynomial, etc.
    }//end Polynomial class
    can anyone help me out? the code i'm using compiles correctly, but it does not change the value of the current coeff variable as i'd like to think it should. any input would be GREATLY appreciated, thanks!

    hey,
    thanks for the reply...
    i am sure that ((Polynomial)tester.retrieve()).getExp() will return an int equal to 'e.' i tried this:
    System.out.println("e="+e);
    System.out.println((Polynomial)tester.retrieve()).getExp());
    if( e == ((Polynomial)tester.retrieve()).getExp() ){
    this.coeff = ((Polynomial)tester.retrieve()).getCoeff() + c;
    System.out.println( "this.coeff = " + this.coeff );
    with that, the output showed that e and the getExp() output were the same. it also showed (as output) that this.coeff did change in value, but when i tried this:
    System.out.println( ((Polynomial)tester.retrieve()).getCoeff() )
    to check if the value changed within the object, it didn't. this.coeff changed, but the actual coeff variable in the object didn't.
    any ideas?

  • Can we set List View Lookup Threshold at site collection level ?

    Hello,
    Presently, we have requirement to set the List View Lookup Threshold  at Site Collection/Sub-Site level instead of web application level.
    Could you please let me know, are there any ways to set
    List View Lookup Threshold setting at Site Collection/Sub-Site level
    in SharePoint 2010 using Powershell/Object Model
    Also, it would be helpful if you colud let me know, upto what extent , we can drill down List View Lookup Threshold setting i.e. SubSite/List/Library-Folder.
    Thanks in advance !

    Hi Sagar,
    We cannot set list view threshold value at sitecollection/subsite level. It can only be set at web application level.
    However we can bypass the 5000 limit using PowerShell command by setting “Enable Throttling”= false for particular list.

  • Linked List  - deleeting nodes - HELP!

    How do I delete all occurences of the nodes with the same parameters in the linked list ?
    example:
    Node1-> Node2 ->Node3->Node4->Node5
    Node1, Node4, and Node5 have the same String value, how do I delete them in one method without breaking the linked list ?
    thanks

    Hi,
    You have iterate thru the linked list remove one by one. Also have look at other collection classes like HashSet or HashMap for fast retrieval.
