In CA Asset Portfolio Management 14.1, a data import fails with the error: 1. You cannot change the Asset Family for this model because there are assets based on this model. 2. Invalid hierarchy data entered for Class.

In CA Asset Portfolio Management 14.1, a data import fails with the errors:  

1. You cannot change the Asset Family for this model because there are assets based on this model. 

2. Invalid hierarchy data entered for Class. 

This error occurs when the data import was written to update assets in a specific asset family, but the input data file contains some records in a different asset family. 

There are a couple of options to handle this type of error:

1.  If you want the data import to remain restricted to a single asset family, then this error is valid and you'll want to remove the bad data records from the input data file.

2.  If you want the records with the different asset family updated with this import, then create a new data import map file that operates on 'across all families'.
