Hello experts,
I'm using PBCS and I would like to know if is possible to delete entire "Period Mapping" to add new rows.

I have a lot of rows (previous project) If I delete application don't remove this rows. Also I try to import period mapping that I need by migration component (from another cloud) but don't delete old rows.
Solution could be delete each row manually...but i have 300 hundred rows...
Is possible to achieve this? Delete period mapping and import period mapping that I want.
Thanks!
