Containing:
Part: N
AVI: N
Syslog: N

Work Around: Had a customization written that will read the values from the legacy I-deas form and then repopulate the values for the properties on the ItemRevision.
Steps to Duplicate:
Add a custom item to your TC 10.1.5 database
Select the custom ItemRevision and open it in BMIDE
Add a property to this itemRevision called Minster Drawn By
Deploy the change to Teamcenter
Import the attached attribute mapping file: attr_allow_null_value.txt
Make a new I-deas part using the custom item type and save to TC. Or import the attached package file.
Add a Minster Drawn By property by editing the properties form and saving it
Migrate the I-deas part using CMM
Check the properties form and see how the Drawn By property is removed
