Inversion in the next year

Hello all ,

we have a problem. Our consolidation frequency is set to period 0 to 16. Document type that are set to be inverted in the next year are not reverse in period one because the last period we really use id the period 12. The period 13 can be used for specific purpose. In the old BCS (EC-CS), period 13 to 16 was automatically reversed in period 1 of the following year. Is ther a way we can make it work in that way. We need entries from certain document type to be inverted from period 12 into period 1 of 2008.

Do I have to remove the special period 13 and up from the cons. frequency ?

Please give your input I need help !!
