Form settings UDF

Hi!

I have created a UDF in the marketing documents called Last_Quot. This is Row-wise as I want the UDF per line item.

This field is available to check/uncheck against in the form settings in some of the transaction screens but is unavailable in some others. For example, I can see it in the form settings of Sales Order, but cannot see it in the form settings of Sales Quotation. I have just upgraded from 2005B to 2007B. It used to work well in 2005B but this is different in 2007B. Is it a bug, or is there a place to enable it? Other UDF's seem to be visible alright.
