Value-Help with fields of data dictionary structure

Hello guys,

is it possible to create a value-help for the fields (not the content!) of a data dictionary structure? I have my custom ddic structure Z1 with the fields A, B and C. Now I have ddic table Z2 where I want to input field-names. Therefor i have a field FIELDNAMES in this table. For this field I want as value-help the names of fields A, B and C of structure Z1. Is this possible?

Regards

Michael
