Defaulting values in complex table drop down fields based on the value selected in other complex table drop down field

Hi Experts,

I am working on Work Manger 5.3 Application.There is tab to add standalone Notifications and related items from Device(iPad).In the Notification Item add screen, there are three fields damage,part and cause.These three field type are Complex table drop down(damage-code group,part-catalog profile,cause-catalog profile complex tables are mapped).Now if i select a value from damage field, that value should be defaulted in to part and cause fields as well .That means the cause and part group will contain the values selected in the damage field.But the user should also be given an option to change the values in part and cause field.If they want to edit the defaulted values in cause and part,drop down should be available to them.

I have tried with update rules for the fields but no luck.Please clarify can this be achieved. The Agentry Client version is 6.0.50.1.

Thanks in advance.

Thanks & Regards,
