How to replace a Financial Dimension in Default Dimensions–Condensed [AX 2012]

In my previous post on Replacing default dimensions, I had provided a job to replace one financial dimension within a default dimension. The job was pretty big and I always thought that Microsoft should have provided some way to do these operations easily. Luckily I found a class that has helped me to condense that job and make it pretty small. I am sharing that job here:
The dimensions for Customer record looks like this before running the job:


Here is the job to change the values. We will change the values for Business Unit, Department and Worker all with this simple job:
static void replaceDefaultDimensionsCondense(Args _args)
{
    /*
     * In this job, we will replace the Business Unit Value from BU-001 to BU-002
     * and fill in the values for Department as Dep-001 and Worker as 114
     */
    CustTable                       custTable = CustTable::find(‘CUS-00004′); //Customer Record containing Financial Dimension
    Struct                          struct = new Struct(); //Structure to hold the dimension values to replace
    container                       defDimensionCon; //Container to prepare the required values and dimension attribute combination
    DimensionDefault                dimensionDefault; //Get the replaced dimension recid
    DimensionAttributeSetItem       dimAttrSetItem; //Table to get active dimensions for the legal entity
    DimensionAttribute              dimAttribute; //Table to get the Financial dimensions
    int i; //For looping

    //Loop for required dimensions
    while select Name, BackingEntityType from dimAttribute
        where dimAttribute.BackingEntityType == tableNum(DimAttributeOMBusinessUnit) ||
              dimAttribute.BackingEntityType == tableNum(DimAttributeOMDepartment) ||
              dimAttribute.BackingEntityType == tableNum(DimAttributeHcmWorker) &&
              dimAttribute.Type              != DimensionAttributeType::DynamicAccount
              join dimAttrSetItem
                where dimAttrSetItem.DimensionAttribute == dimAttribute.RecId &&
                      dimAttrSetItem.DimensionAttributeSet == DimensionCache::getDimensionAttributeSetForLedger()
    {
        //Add the Dimension name and display value to struct
        if (dimAttribute.BackingEntityType == tableNum(DimAttributeOMBusinessUnit))
        {
            struct.add(dimAttribute.Name, ‘BU-002′);
        }
        else if (dimAttribute.BackingEntityType == tableNum(DimAttributeOMDepartment))
        {
            struct.add(dimAttribute.Name, ‘DEP-002′);
        }
        else if (dimAttribute.BackingEntityType == tableNum(DimAttributeHcmWorker))
        {
            struct.add(dimAttribute.Name, ’114′);
        }
    }

    //Prepare the container
    defDimensionCon += struct.fields();

    for (i = 1; i <= struct.fields(); i++)
    {
        defDimensionCon += struct.fieldName(i);
        defDimensionCon += struct.valueIndex(i);
    }

    //if there are fields in struct
    if (struct.fields())
    {
        //Get the DimensionAttributeValueSet table’s Record ID
        dimensionDefault = AxdDimensionUtil::getDimensionAttributeValueSetId(defDimensionCon);
      
        //Update to Customer
        ttsBegin;
        custTable.selectForUpdate(true);
        if (custTable.DefaultDimension)
        {
            custTable.DefaultDimension = DimensionDefaultingService::serviceMergeDefaultDimensions(dimensionDefault, custTable.DefaultDimension);
        }
        else
        {
            custTable.DefaultDimension = dimensionDefault;
        }
        custTable.doUpdate();
        ttsCommit;
    }
}

Dimensions after running the job:


Pretty Neat!
The class AxdDimensionUtil is pretty handy to do all these stuff.
