Hello Prabhu,
     From your doubt, what I understand is that, You have designed a header in Master Page. You need to fill this header using the Item table which is already designed in the design view(body page). Means you want to fill the Item details(which are in body page) into the header(which is in the master page).
To read the contents from body page into master page, you need to write Javascript code on the header fields(which is in the master page) in the Layout Ready Event.
For example, if you want to fill the field Order_description in header(master page) from the column Order_Description which is in the Item table(body page)
In the form layout, select the order_description field and in the event READY LAYOUT write the below JavaScript code.
var currpage = xfa.layout.page(this);------> Get the current page
var fields = 0;------> Variable to store the number of fields in that page.
fields = xfa.layout.pageContent(currpage-1, "field", 0); ------> Get the number of fields
for ( i=0; i<= fields.length-1; i++ ) ------> Loop on each field on the page
    if ( fields.name == "ORDER_DESCRIPTION" ) ------> Check if the corresponding field is in the Item table
         this.rawValue = fields.item(i).rawValue; ------> Assign that value in the Header field
Repeat the same steps for other fields in the Header. This will work for all Purchase Orders spanned across multiple pages.
