R12 Descriptive Flex Field with Value Set based validation on Table dedicated to Customer Framework

Hello

I have defined a Descriptive FlexField segment assigned to Customer Address as defined in 11i and I received this error message "No field listener is registered to resolve field ADDR.CUSTOMER_ID referenced by the flexfield with application short name AR and name RA_ADDRESSES_HZ. Please contact your system administrator"

Value set table validation contains is

select *

from hz_cust_acct_sites hcs, hz_cust_site_uses hsu

WHERE hcs.cust_account_id = :ADDR.CUSTOMER_ID

 AND hcs.status = 'A'

 AND hsu.cust_acct_site_id = hcs.cust_acct_site_id

 AND hsu.site_use_code = 'INV'

 AND hsu.status = 'A'
