how to filtering portal entry with 2 fields, for example

User-----Application-----access type

-------------------------------------

Jon-----Purchasing-------Read Only

Harry---Shipping---------Full Acces

if i entry Jon with Purchasing again, i want to show error duplicate message.

Can you help me..? thank you

In the file where you have User Application fields create Calculation field =User&"_"&Application then create self relation by this field. Now validations for User and Application fields Count(Self::User)<2.
