Writing new Data record ( key figure values are initial)

Hello,

Could somebody help me out with following problem!

I create new data records in an exit function which dosen't always compute to non-initial key figures. Simpley put, in new data records, the key-figures gets computed to initial values. Would it be possible to write this new data record with initial Key-Figures without changing the data-model of the Cube!

Data record for example

[ {Char1, Char2}, {keyf1 = 0, keyf2 = 0} ]
