I am sending print request using below xml on FTP.

<?xml version="1.0" standalone="no"?>
<label _FORMAT="ITEM.ZPL">
    <variable name= "PN_VALUE">test PN Value</variable>
    <variable name= "DESC_VALUE">test DESC value</variable>
    <variable name= "UOM_VALUE">test UOM Value</variable>
    <variable name= "DATE_VALUE">test Date VAlue</variable>
    <variable name= "PO_VALUE">Test PO</variable>
    <variable name= "PROJECT_VALUE">Test project</variable>
    <variable name= "SUPPLIER_VALUE">Test Supplier name</variable>
    <variable name= "RECEIPT_VALUE">Test Receipt value</variable>
    <variable name= "LOTNUMBER_VALUE">Testlot12</variable>
</label>undefined</labels>

Please find the attached generated label after sending xml request to FTP. All fields display on the label has been changed based on xml variable. but variable which are mentioned in barcode was change. Below are the output of generated barcode after scanning.

Generated Label:

barcode output : 10LOTNUMBER_VALUE400PO_VALUE89901PN_VALUE89902DESC_VALUE89903UOM_VALUE89904PROJECT_VALUE89905SUPPLIER_VALUE89906RECEIPT_VALUE89907DATE_VALUE

I did not got any idea why variable inside barcode was not changed ?
