X++ Display Financial Dimension Value

I found this useful post https://sumitsaxfactor.wordpress.com/2011/12/16/getting-individual-dimension-combination-valuesdimension-storage-class-ax-2012/ written by Sumit Loya.

As real beginner on Financial module. This is a simple to show financial dimension from table/class. For example,  General ledger -> Common -> Trial Balance -> Click Journal entries 'Balance' -> Choose a journal and click 'Transaction Origin'.

Only input of this code is RecId of table GeneralJournalAccountEntry. In short words, this table keeps the key of LedgerAccount and Journal.

static void getDimensionCombinationValues(Args _args)
{
    // DimensionAttributeValueCombination stores the combinations of dimension values
    // Any tables that uses dimension  combinations for main account and dimensions
    // Has a reference to this table’s recid
    DimensionAttributeValueCombination  dimAttrValueComb;
    //GeneralJournalAccountEntry is one such tables that refrences DimensionAttributeValueCombination
    GeneralJournalAccountEntry          gjAccEntry;
    // Class Dimension storage is used to store and manipulate the values of combination
    DimensionStorage        dimensionStorage;
    // Class DimensionStorageSegment will get specfic segments based on hierarchies
    DimensionStorageSegment segment;
    int                     segmentCount, segmentIndex;
    int                     hierarchyCount, hierarchyIndex;
    str                     segmentName, segmentDescription;
    SysDim                  segmentValue;
    ;

    //Get one record for demo purpose
    gjAccEntry = GeneralJournalAccountEntry::find(5642191935);  //put the input here

    setPrefix("Dimension values fetching");
    //Fetch the Value combination record
    dimAttrValueComb = DimensionAttributeValueCombination::find(gjAccEntry.LedgerDimension);
    setPrefix("Breakup for " + dimAttrValueComb.DisplayValue);

    // Get dimension storage
    dimensionStorage = DimensionStorage::findById(gjAccEntry.LedgerDimension);
    if (dimensionStorage == null)
    {
        throw error("@SYS83964");
    }

    // Get hierarchy count
    hierarchyCount = dimensionStorage.hierarchyCount();
    //Loop through hierarchies to get individual segments
    for(hierarchyIndex = 1; hierarchyIndex <= hierarchyCount; hierarchyIndex++)
    {
        setPrefix(strFmt("Hierarchy: %1", DimensionHierarchy::find(dimensionStorage.getHierarchyId(hierarchyIndex)).Name));
        //Get segment count for hierarchy
        segmentCount = dimensionStorage.segmentCountForHierarchy(hierarchyIndex);

        //Loop through segments and display required values
        for (segmentIndex = 1; segmentIndex <= segmentCount; segmentIndex++)
        {
            // Get segment
            segment = dimensionStorage.getSegmentForHierarchy(hierarchyIndex, segmentIndex);

            // Get the segment information
            if (segment.parmDimensionAttributeValueId() != 0)
            {
                // Get segment name
                segmentName = DimensionAttribute::find(DimensionAttributeValue::find(segment.parmDimensionAttributeValueId()).DimensionAttribute).Name;
                //Get segment value (id of the dimension)
                segmentValue        = segment.parmDisplayValue();
                //Get segment value name (Description for dimension)
                segmentDescription  = segment.getName();
                info(strFmt("%1: %2, %3", segmentName, segmentValue, segmentDescription));
            }
        }
    }
}

The result looks like below.
