Here you can select a dimension value code for a dimension. To see the dimension value codes you have set up for this dimension in the Dimension Values window, click the AssistButton in the field.
If you enter a dimension value code in this field, the program will use the corresponding dimension value as a default each time you enter the account on an entry line. Default dimension values are only suggestions and you can change them on the entry line, for example in a journal.
