This is all I can find about creating a lookup I need to use in a script......

Use As Lookup
You use the Use as Lookup column to select a dimension for a custom lookup table. When Use
as Lookup is selected, the Enabled field cannot be used. The custom lookup dimension is used
only for custom scripting.

What I did,
In MetaData>Dimension I checked "Use as lookup" for the dimension I want to use...

Where do I load the lookup values? To the mapping table for that dim? I have 6000 locations and I need to have one table to maintain...

I need to load to one table for all lookup values is my understanding...is that the case?

Thanks,
