How to calculate GST for Purchase order Confirmation

Description: How to calculate the GST taxes on purchase order confirmation. Here i am sharing some code to get Taxes details (IGST/CGST/SGST) in AX.

static void GSTForPOLineWise(Args _args)
{
    vendPurchOrderJour                  vendPurchOrderJour;
    PurchLineAllVersions                ObjPurchLineAllVersions;

    ITaxDocumentComponentLineEnumerator componentLineEnumerator;
    ITaxDocumentComponentLine           componentLineObject;
    ITaxDocumentMeasureEnumerator       measureEnumerator;

    ITaxDocumentLine                    line;
    ITaxDocumentLineEnumerator          lineEnumerator;

    TaxAmount                           taxAmount,taxValue;
    TaxComponent_IN                     taxComponent;
    ;

    vendPurchOrderJour = vendPurchOrderJour::findRecId(VendPurchOrderJour::findByPurchId("PurchaseOrderId").RecId);
    taxDocument = TaxBusinessService::getTaxDocumentBySource(vendPurchOrderJour.TableId, vendPurchOrderJour.RecId);
    //Tax Document not null,GST Apply start
    if(taxDocument != null)
    {
        componentLineEnumerator = taxDocument.componentLines();
        lineEnumerator = taxDocument.lines();
        //Tax Document not null,GST Apply start-1
        if (taxDocument)
        {
            //lineEnumerator for Current line taxDocument start
            lineEnumerator = taxDocument.lines();
            while(lineEnumerator.moveNext())
            {
                //Getting Current line RecId for GST start
                line = lineEnumerator.current();
                line.setTaxDocument(taxDocument);
                if(line.originSourceRecId() != 0 && line.getInvoiceTax().value() != 0)
                {
