Custom Metadata fields
I am still working through my upgrade from 10g to 12c. I have successfully installed and have 12c up and running. I used the CMU to pull over the configurations from 10g to 12c. Most of them worked great. One issue is with Custom Metadata fields. During the configuration upload it through an error on my xState field. After the configuration upload finished, I went and launched Configuration Manager to manually create the missing field. I went to the Information tab and clicked Add...
I filled in the input fields duplicating what I had in 10g. Field caption as State, Field Type as Memo, Field Order is 57. Checked Enable on User Interface and Enable for Search Index.
