Activating fields in DGP3 for phrases

Hi

There are a number of fields within DGP3 where there is no ability to add a list of phrases. When you go into the "Edit Phrase Set-to-Attribure Assignment" function and select the relevant attribute e.g. Packaging Group, you get the error 'No phrase-enabled characteristic is available for class SAP_EHS_1025_003".

When I go into CL02 to look at this class, it doesn't show it so it doesn't appear to exist.

Do I need to create these classes each time, or is there a step in the config that I've missed.

Thanks for any help in advance !

Cheers

Alistair
