SNP1 tab Penalty Cost updation not happen through LSMW

Hi,

We have currently upgraded from SCM 5.0 to SCM 7.0. We used to run LSMW for Penaly Cost updation in SNP1 tab of production master, but after upgradtion we are not able to run the same LSMW. We created the new one also but LSMW is not able to record the Penalty Cost Updation. Does Anybody have solution for this problem .....
