Financial Dimensions blank in value model

Hi ,
User has purchased an FA from the Purchase order , after posting invoice ,when user drill down the FA value model of that asset – financial dimensions are blank ( even user assigned the dimensions).
Did anybody face the same problem ?

Did anybody find the solution ?

The fixed asset is tied to the group which is tied to the model, meaning you define the dimensions on the model and these are then applied to teh FA, these is no push down from PO to the model group, it would make no sense as it would impact on all FA’s in that group.
