We are upgrading from IFSAPPS8 to IFSAPPS10

On sales Parts in IFS8 we had fields PACKAGE_TYPE, PALLET_TYPE, PROPOSED_PALLET_QTY, PROPOSED_PARCEL_QTY, VOLUME, WEIGHT_GROSS,  WEIGHT_NET.

In IFSAPPS10 , above mentioned fields are not available on salespart screen and not mentioned in the package sales_part_api, but he fields are still in the table. In upgrade scripts, I cannot see that data from above fields is migrated into other tables. 

My question : we have data in mentioned fields, but this data is currently not accessable in an IFS10-screen. How to deal with this?

Did somebody encounter the same problem? Maybe for some other LU?
