EBS 12.1.3: Why does Payables Open Interface allow Batching when Batch Control is not Enabled?

Hello,

Why does Payables Open Interface Import allow Batching when Batch Control is not Enabled?

Profile Option "AP: Use Invoice Batch Controls" is set to No. However I am able to specify a "Batch Name" (instead of the default "N/A") while submitting "Payables Open Interface Import" via fnd_request.submit_request from a PL/SQL Wrapper program.

I am doing this for records that I populate in AP_INVOICES_INTERFACE and AP_INVOICE_LINES_INTERFACE for Received but not Invoiced PO Distributions using a Custom Source "eCycle Auto Invoice creation from PO" (XXEC_AUTO_INV_FROM_PO).

The Import request runs successfully and creates the Invoices. I am then able to search for these Invoices in the Invoice Workbench using the Batch Name I provided above.
