PRGN_COMPRESS_TIMES in SAP R/3 4.6

Hi SAP Security comrades,

I've a question from SAP 4.6 system - we need to remove the expired roles (duplicate ones) from users account. I checked in SA38 to run the program PRGN_COMPRESS_TIMES but it says "

Program PRGN_COMPRESS_TIMES does not exist"

Is there any other program or way to remove the expired roles in 4.6 ?

Thanks,

Daya

P.S Manually removing would be the end of the world / last option, which we don't want to get in
