In table, iby.iby_external_payees_all column remit_advice_delivery_method is always null

Hello Experts,

We call oracle api, apps.pos_vendor_pub_pkg.create_vendor, to create records in table iby.iby_external_payees_all.

We're expecting these columns to be populated:

remit_advice_delivery_method

remit_advice_email

Column, remit_advice_email, gets populated properly.  But for whatever reason, column remit_advice_delivery_method is not getting updated and is always null.

Is there a different api we should be calling?

Can someone please help?

Thanks
