Printing problem

Hi

I have got a peculiar problem, it is....

we print all the billing documents due for printing in background by using RSNAST00 program. with Application ID as V3 and output type as ZRAD (custom defined output type)

Now the problem is, two variables values are appearing wrongly in the output. I did the debugging and found that the these two varaibles are populated correctly in the print program. But when i see the spool, its different.

I could not able to come to a conclusion, please help me in solving this

regards
