INSTEAD of Trigger View for an Oracle EBS New form development

Question

Hello,
I am developing a new EBS form based on a database view.
This form is an EBS form will run in an 11.5.10.2 environment and developed using 6i.
The form has one data block that is based on the view. The view is joined and based on following tables.
Hz_Parties Hp,
Hz_Cust_Accounts
Hz_Cust_Acct_Sites_All
Hz_Party_Sites
Hz_Locations
Ra_Salesreps_All
Hz_Cust_Site_Uses_All
Ar_Vat_Tax_All
xx_custom_table t
The view is inherently not updatable. Therefore, I am thinking to write an INSTEAD OF trigger on the view. The question. The form which is based on the view is require to update Oracle EBS tables mentioned above. As you know, there are APIs available to update above tables.
Typically, you would write API in a program unit in the form and call from triggers. But here the form is based on the view. And to support DMLs on the view, I HAVE TO write INSTEAD of trigger(or that is the only way i know) so the question is:
1. Do I write these APIs under INSTEAD of triggers?
2. Or, I write these API in the form triggers and write DML referencing OLD and NEW values in INSTEAD of trigger? Where, these OLD and NEW values will refer on above tables.
Please advise.
And lastly, Do I have to write an INSTEAD of trigger? The USER_UPDATEABLE_COLUMNS view for this table shows no columns are updateable at the moment
Thanks,
A

As you know, there are APIs available to update above tables.No, I don't B-) You'd better ask this in the eBusiness Suite form, as this is very EBS, not Forms, specific.
In general, I would say that in this case you can use the EBS API's in the instead of trigger, not in the form.
Or you can base the form on stored procedures, not directly on the view.
