Thank you very much for the reply.I wil try soon whatever you suggested and
let you know in case of any anomaly.
For the time being may i say that NOTE-1 in IRRPROFILE and NOTE-2 in
DCYTIMES are not valid in light of the explanation you provided just to
make sure that users in future are not confused.
Thank you and have a nice evening
