Asset revaluation for AUCs

Hello,

We are implementing the asset revaluation in our AM module that is already working without revaluation areas (these are being maintained in an spredsheet)

All the configuration is done and working, but now I face a problem with the data take over: when trying to load values in the revaluation areas I am undertain on how to load the AUCs..the fields to get the values updated are in grey, I tried creating a transaction type specific for take overs, but it is not possible to create a revaluation one...

Any idea?

Thanks a lot!
