Issue with hz_cust_account_v2pub.update_cust_account API

Question

Hello,
I am facing a strange problem. I am updating oracle customers via hz_cust_account_v2pub.update_cust_account API. This is on 11.5.10.2
The problem is, when I pass NULL values to customer class, customer type and warehouse_id fields, The API does not apply the same in database. For e.g. If warehouse_id is 91 and I need to update that warehouse ID to NULL using this API, it does not work.
Even after applying a NULL update through API, the value 91 still remains un-updated. Same is the story with Customer Class and Customer Type fields.
All other updates are just working fine. Even if I pass other values to these fields in question, they work just fine. Only when you are passing NULL this problem arises.
Any idea why? Please Advise.

Hello,
Oracle allows you to default many of the values for their API's. When you do this they will not delete the values but leave them unchanged. Since the API cannot tell if you set the value to be NULL explicitly, it is not clearing the value. When you want to actually clear a value you need to set it to a specific value. The FND_API package spec has these defined. I cannot connect my my EBS instance at the moment, so I cannot remember if it is the G_MISS or G_NULL variables that you want. You will need to double check that.
p_cust_account_rec.customer_class_code := FND_API.g_null_char;  -- This is the problem. Not updating Null
p_cust_account_rec.customer_type := FND_API.g_null_char;    -- This is the problem. Not updating Null
p_cust_account_rec.ship_sets_include_lines_flag := 'N';
p_cust_account_rec.warehouse_id := FND_API.g_null_num;     -- This is the problem. Not updating NullHTH,
