POS - Consolidate the Receipt (Stock Management)

This code has been copied from this forum thread.

These scripts will consolidate the receipt (Stock Management) by, removing duplicate item entries and adding their units to the first entry of the item.

1) Edit stateTransition method in StockManagement (com.openbravo.pos.inventory) class

Put before saveData() method:

else if (cTrans == ' ' || cTrans == '=') {
  if (m_invlines.getCount() == 0) {
    // No podemos grabar, no hay ningun registro.
    Toolkit.getDefaultToolkit().beep();
  } else {
    //HERE!!!
    saveData();
  }

the following code:

               int numlinessm = m_invlines.getCount();
               for (int icounter = 0; icounter < numlinessm; icounter++) {

                   current_stockmgtline = m_invlines.getLine(icounter);
                   current_unitsm = current_stockmgtline.getMultiply();

                   if (current_unitsm != 0) {
                       for (int jcounter = icounter + 1; jcounter < numlinessm; jcounter++) {
                           loop_stockmgtline = m_invlines.getLine(jcounter);
                           loop_unitsm = loop_stockmgtline.getMultiply();
                           String current_productidsm = current_stockmgtline.getProductID();
                           String current_productatt = current_stockmgtline.getProductAttSetInstId();
                           String loop_productidsm = loop_stockmgtline.getProductID();
                           String loop_productatt = loop_stockmgtline.getProductAttSetInstId();
                           if (loop_productidsm.equals(current_productidsm) && (loop_unitsm != 0) && ((loop_productatt!=null && loop_productatt.equals(current_productatt)) || (loop_productatt==null)&&(current_productatt==null)) ) {
                               current_unitsm = current_unitsm + loop_unitsm;
                               loop_stockmgtline.setMultiply(0);
                           }
                       }
                       current_stockmgtline.setMultiply(current_unitsm);
                   }
               }
               for (int icounter = numlinessm - 1; icounter > 0; icounter--) {
                   loop_stockmgtline = m_invlines.getLine(icounter);

                   }
               }
