How to change size of a nvarchar DAC field in an existing screen ?

Thank you for the reply @sweta68 !

@oshadarodrigo64 yes you can change the length of custom field in existing screen.In the project editor for that field we can customize attributes and change the length.

To change the length, you need to add the PXDBString attribute and in a brackets specify the length whiсh you want. Also value of string lenght should be the same in code, SQL, and customization. If it's not it could be a data lost. Also you need change value in SQL table and than you need to press Reload from Database button in Database Scripts in your customization package

 [PXDBString(100, IsUnicode = true, InputMask = "")]
        [PXUIField(DisplayName = "Description")]
        public virtual string OrderDesc { get; set; }
        public abstract class orderDesc :
        PX.Data.BQL.BqlString.Field<orderDesc>
        { }

To change value length using customization, you need to click Increase Column Length under Database Scripts and in the window select needed table, then the field and after that set the desired length
