KB10243: How to change the Mapping Method of an Attribute Form from Automatic to Manual using the MicroStrategy 9.x Server SDK

Each Form of an attribute has a setting called 'Mapping Method'. When this is set to Automatic, the attribute form will automatically have access to every column with the same name in every table associated with the project. If this setting is 'Manual,' then the user can select which tables this attribute should have access to. It is possible to programmatically toggle this setting using the Server SDK. To achieve this, perform the following steps:

1. Declare the variables:
   

   
   Dim strAttributeID as String
   Dim MySource as IDSSSource
   Dim MySession as IDSSSession
   Dim oInfo as IDSSObjectInfo
   Dim oAttribute As IDSSAttribute
   Dim oPGroup As IDSSPropertyGroup
   Dim oPSet As IDSSPropertySet
   Dim oProp As IDSSProperty
   Dim strPropName As String
   Dim strPropValue As Variant
   Dim oDomDoc As New DOMDocument
   Dim oNodeList As IXMLDOMNodeList
   Dim oNodeMap As IXMLDOMNamedNodeMap
   Dim myNode As IXMLDOMNode
   Dim Node1 As IXMLDOMNode
   Dim Node2 As IXMLDOMNode
   Dim r As Integer

   
    
   
2. Retrieve the following attribute object:
   
   Please Note: For simplicity, only one attribute is being modified in this example. It is possible to run this on all attributes in the project. To do this, you must first create an object of type IDSSSearch to return all attributes in the project. Next, create a For loop that will iterate through the entire collection of attributes. This For loop should contain all code from steps 3 to 6. For instructions on how to create the search object please reference KB6100-7X0-0094 - "How to search an object in Strategy SDK 7.x"
   

   
   strAttributeID = "8D679D4811D3E4981000E787EC6DE8A4"
   Set MySource = MySession.Component(DssRoleObjectSource)
   Set oAttribute = MySource.FindObject(strAttributeID, DssTypeAttribute)

   
    
   
3. This information is stored as a property set which is available from the IDSSObjectInfo Interface:
   

   
   Set oInfo = oAttribute.Info
   Set oPGroup = oInfo.PropertySets

   
    
   
4. Create a for loop to iterate through all property sets to find the "Expressions'" node:
   

   
   For Each oPSet In oPGroup
   If oPSet.Info.Name ="Expressions" Then

   
    
   
5. The return type of this property will be in XML format. This value can be loaded into an XMLDOM Document where it can be parsed and the value changed:
   

   
   oDomDoc.async = false
   oDomDoc.loadXML (oProp.Value)
   oDomDoc.Validate
   
   Set oNodeList = oDomDoc.getElementsByTagName("E")
   For r = 0 To oNodeList.Length - 1 Step 1
   Set oNodeMap = oNodeList.Item(r).Attributes
   Set Node1 = oNodeMap.getNamedItem("MM")
   oDomDoc.getElementsByTagName("E").Item(r).Attributes.getNamedItem("MM").nodeValue = 2
   Next

   
    
   Complete the outer For loop and save the object:
   

   
   oProp.Value = oDomDoc.xml
   oAttribute.Info.Save
   End If
   Next oPSet
