Passing values to the Validation Rule error message

Question

Hello
Help me please
I have the following inquiry :
I am using JDeveloper 10.1.3
I am working on ADF and JSF environment
I have entity object called "Invoices"
and I have the following business rule
" Total purchases from any supplier should not exceed 5000 $ per month "
I am using a validation query to check for the purchases from
specific supplier and validate the Amount.
and I want the message for this validation rule to be :
" Total purchases for this supplier is X , you cannot purchase more than 5000 $ "
where X is variable depending on the supplier ?
I used to do this in Oracle Forms and PL-SQL
I want to generate messages like :
Total purchases for this supplier is 6500 , you cannot purchase more than 5000 $
Total purchases for this supplier is 5250 , you cannot purchase more than 5000 $
???
