Restrict customer to resp in sales order

 Hi,

We used Form personalization to restrict to show the one specific customer for specific Responsibility.

Trigger Object - NEW ITEM INSTANCE

Trigger Object - ORDER.SOLD TO

We create Record group and attach in LOV of CUSTOMER_NUMBER. But still we are able to see that customer in sales order form.

select acct.account_number account_number, acct.account_name account_description,

party.party_number registry_id, party.party_name party_name,

party.party_type, acct.cust_account_id cust_account_id,

party.email_address email_address, nvl(party.gsa_indicator_flag,'N') gsa_indicator
