Problem for Function RSPO_RGET_PAGE_NUMBER

Hi,

I've to call the function RSPO_RGET_PAGE_NUMBER to get the no. of pages.

I know I have to export the parameter X of type TSP01SYS to this function, i.e.

CALL FUNCTION 'RSPO_RGET_PAGE_NUMBER'

EXPORTING RQ = IRQ

IMPORTING PAGES = ITLOG-NOFPAGE.

I defined IRQ as

DATA IRQ LIKE TSP01SYS.

I have an internal table itab storing the info from TSP01 and TSP02,

I just want to copy all the data from itab to IRQ,

MOVE-CORRESPONDING itab TO IRQ.

this just move a line to IRQ,

but i want to append all the data from itab to IRQ,

how to do so?

Thanks.
