Problem Adding BOM using Product Trees Object

Question

Hey I am having problems with the following code:
qProductTree = (SAPbobsCOM.ProductTrees)this.m_SboAddon.SboCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oProductTrees);
int RetVal = 0;
qProductTree.TreeCode = "productTree1";
qProductTree.TreeType = SAPbobsCOM.BoItemTreeTypes.iProductionTree;
qProductTree.Quantity  = 5;
qProductTree.Items.ItemCode = "test1";
qProductTree.Items.Price = 20;
qProductTree.Items.Quantity = 1;
qProductTree.Items.Currency = "Eur";
qProductTree.Items.Comment = "test comment";
qProductTree.Items.IssueMethod = SAPbobsCOM.BoIssueMethod.im_Manual;
RetVal = qProductTree.Add();
string errMsg;
int errCode;
if (RetVal != 0 )
     this.m_SboAddon.SboCompany.GetLastError(out errCode, out errMsg);
     MessageBox.Show(errMsg);
I get an error message with ID 2028 which when I look it up in the SDK it states DataSource - No Data found.
Any ideas?

Hi Laura!
In DI reference you can find topic 'Add a Bill Of Material sample', hope it'll help you.
Note, that there are some lines in that sample:
    Dim vItem As SAPbobsCOM.Items
    <b>Set vItem = vCmp.GetBusinessObject(oItems)</b>
    Dim vProdTree As SAPbobsCOM.ProductTrees
    Set vProdTree = vCmp.GetBusinessObject(oProductTrees)
           'Get the Item I want to create as Product Tree
    <b>RetVal = vItem.GetByKey("MyProdTree")</b>
    'Set Values to the fields
    vProdTree.TreeCode = <b>"MyProdTree"</b>
    vProdTree.TreeType = iProductionTree
In my mind, you should find an existing Item (via GetByKey) before you create ProductTree.
