Answer 1

Before:
//Populate the item detalis
table_item.appendRow();
table_item.setRow(1);
table_item.setValue("000010","ITM_NUMBER");
table_item.setValue("AA01","PO_ITM_NO");// can be changed
table_item.setValue("IAD-SC3000","MATERIAL");
table_item.setValue(CUSTMAT,"CUST_MAT");// can be changed
table_item.setValue("20041212","REQ_DATE");// can be changed in yyyymmdd
table_item.setValue(RQTY,"REQ_QTY");// can be changed Qty * 1000
table_item.appendRow();
table_item.setRow(2);
table_item.setValue("000020","ITM_NUMBER");
table_item.setValue("AA01","PO_ITM_NO");// can be changed
table_item.setValue("IAD-SC3000","MATERIAL");
table_item.setValue(CUSTMAT,"CUST_MAT");// can be changed
table_item.setValue("20041212","REQ_DATE");// can be changed in yyyymmdd
table_item.setValue(RQTY,"REQ_QTY");// can be changed Qty * 1000
Try to add:
//Populate the item detalis
table_item.appendRow();
table_item.setRow(2);
table_item.setValue("000020","ITM_NUMBER");
table_item.setValue("AA01","PO_ITM_NO");// can be changed
table_item.setValue("IAD-SC3000","MATERIAL");
table_item.setValue(CUSTMAT,"CUST_MAT");// can be changed
table_item.setValue("20041212","REQ_DATE");// can be changed in yyyymmdd
table_item.setValue(RQTY,"REQ_QTY");// can be changed Qty * 1000
table_item.appendRow();
table_item.setRow(2);
table_item.setValue("000020","ITM_NUMBER");
table_item.setValue("AA01","PO_ITM_NO");// can be changed
table_item.setValue("IAD-SC3000","MATERIAL");
table_item.setValue(CUSTMAT,"CUST_MAT");// can be changed
table_item.setValue("20041212","REQ_DATE");// can be changed in yyyymmdd
table_item.setValue(RQTY,"REQ_QTY");// can be changed Qty * 1000
