Hi Friends, This is my first post on this forum. I have created an object with one attribute defined as a lookup - string. The table that was created at the back-end had this attribute field size of varchar2(20 bytes). But I want this to be a bit longer .. say 200 bytes. I checked the object attribute settings but could not find an option to increase the field size there.Also tried altering the table column value to 200 bytes. But still when I try to create an instance and select a value greater than 20 chars from the lookup, it throws 'Value too large' error. I am using Clarity 7.5.3. any help is much appreciated. Thanks.
