Hi Bhavani,
What Abhilash suggestion is perfectly suitable to your problem, if you feel it is lengthy if the crosstab you placed in group1 then you placed that text object "Customer" in page header and right click on grey area of "PageHeader" go to Section Expert > Select Page header > check 'Underlay Following Sections'.
Then the "customer" text Object will display on each page of crosstab.
Hope the above information will help you...
