Groups of companies

sir in case of groups of companies, a member company has a right to not offset its current year trading losses against its current year other income and simply pass it on to some other member company which has Total taxable profits in excess of this company’s trading losses?

i understand that there is a strict rule for c/f losses to be first offset against other income of current year within the company (before opting for a group transfer), but am not sure if the same rule applies for current year losses too?
