modify a report

hi all i have a requirement where i need to modify a report,

where i have to use gui_upload instead of ws_upload,

here in the internal table i have a feild naming anz_erl(2) .

which after uploading is moved like ths--> MOVE inttab-anz_erl TO anz_erl.

the feild where it is moved is declared as integer ie anz_erl type i.

and my flat file contains the value of anz_erl as character and so the program is

throwing a dump , convt_no_number

can you please tell me a remedy of thhs? i cnt change the global declaration

high points will be given

thnkx
