CPE formula evaluation in purchasing docs

Hello,

Is anyone using CPE in MM Contracts or Purchase Orders?   Using GR posting date as  Ref Date Routine -  I cannot evaluate formula with delivery date in future and this is causing problems.    Error: quote period is completely in the future. 

Have tried numerous sulutions - Offset Routines and Badi helps but am no longer able to post GR and accrue using daily quotes?

Thanks

Diane
