Below are the steps to create Supplier contacts in Oracle EBS R12.
AP_SUP_SITE_CONTACT_INT interface used in 11i for loading supplier contact. Currently in R12 contacts can not be loaded using the interface table.

ap_vendor_pub_pkg.create_vendor_contact API is used in R12 and the program has to be registered as a concurrent program.

### Sample R12 Code

v_party_usg_assignment_id := NULL;
v_relationship_id := NULL;
v_directional_flag := NULL;
v_rel_rowid := NULL;
fnd_file.put_line (fnd_file.LOG,
‘Vendor code :’
|| rec.vendor_name
|| ‘  Vendor site code :’
|| rec.vendor_site_code
|| ‘  Person Last Name : ‘
|| rec.person_last_name
l_vendor_contact.vendor_id := rec.vendor_id;
l_vendor_contact.vendor_site_id := rec.vendor_site_id;
l_vendor_contact.org_id := rec.org_id;
l_vendor_contact.person_first_name := rec.person_first_name;
l_vendor_contact.person_middle_name := rec.person_middle_name;
l_vendor_contact.person_last_name := rec.person_last_name; :=;
l_vendor_contact.email_address := rec.email_address;
p_init_msg_list := fnd_api.g_true;
p_commit := fnd_api.g_false;
x_return_status := NULL;
x_msg_count := NULL;
x_msg_data := NULL;

IF rec.process_flag = ‘I’
fnd_file.put_line (fnd_file.LOG, ‘Creating contacts….’);
(p_api_version             => p_api_version,
p_init_msg_list           => p_init_msg_list,
p_commit                  => p_commit,
x_return_status           => x_return_status,
x_msg_count               => x_msg_count,
x_msg_data                => x_msg_data,
p_vendor_contact_rec      => l_vendor_contact,
x_vendor_contact_id       => l_vendor_contact.vendor_contact_id,
x_per_party_id            => l_vendor_contact.per_party_id,
x_rel_party_id            => l_vendor_contact.relationship_id,
x_rel_id                  => l_vendor_contact.rel_party_id,
x_org_contact_id          => l_vendor_contact.org_contact_id,
x_party_site_id           => l_vendor_contact.party_site_id
error_handling (rec.r_id, x_return_status, x_msg_count, x_msg_data);
fnd_file.put_line (fnd_file.LOG, ‘*************’);

How to create RMA in Oracle Order Management:

I am taking the case of creation of Return Sales Order with Receipt and Credit Memo.

1.Create New Sales Order with Order Type = “Return Only . ( we can take Mixed or any other that allow return line)

2.Since Header Order Type is “Return Only”, based on the transaction Type Setup ,  System will default Line Type .In transaction type set the Default RMA = “Return (Receipt)” , with this Setup system will populate the Line Type = “Return (Receipt)”  , enter other details like
Item #
Qty etc.

3.Go to Return tab ( Lines) and Enter Return Reason (There is LOV for Return Reason select any relevent value from LOV ).
4.Book the RMA.

5.Requery the RMA , check the Line Status , It should be “Awaiting Return”.

6.Select Receipt (Purchasing Responsibility) 

7.Goto Customer Tab and Enter the RMA Num .

8.Press Find Button.

9.Ignore the receipt Header , and go to Receipts form 

10.Select the line

11.Press Save,System will ask for the Sub Inventory.Best bet is enter “Stores” ( Here I am taking the case Routing = Direct Delivery)

12.Press Save Button. Save action will automatically submit the “Receiving Transaction Processor (RTP) concurrent Program.

13.Check Order line status , it should be “Returned”.

14.Go to View > request . Submit Concurrent Program “Workflow background Process”
              with Item Type = OM Order Line
              Process Deferred = Yes
              Process Timeout = No.

Query Order line again , Status Should be “Closed”

15.Step # 14 also submit “Autoinvoice” concurrent Program.
16.Goto Transaction (Receivable Responsibility)

            Go to Find Window
             Enter Sales Order # in Sales Order Number Field
             Press Find
System should display your Invoice (Credit memo)

Examine the Invoice and you are good to go.
