Manage Contract Notes - can we customise the Notes Type value set

EBS - Oracle Purchasing R12.2.9

Hello,

I am trying to update an existing value set in BWC.

In an agreeement, under the actions drop down, there is an option to 'Manage Contract Notes'.

If I add a new note, there are a list of values for the 'Note Type'.

As standard, these include: Contact Supplier, Extend Termination Date, Initiate Terminate etc.

I cannot find these list of values, are you able to provide guidance on where these are held, what they are called and whether these can be updated?

Thanks in advance.
