Error Creating Supplier Site

Hi,

        I am trying to create a supplier site for an existing supplier using the API but whenever I try to set the supplier liability account i get the following errors.

ACCTS_PAY_CCID is invalid-

AccountsPay Code Combination ID is invalid-

Invalid Payee context values. Org parameters exist only with party site and supplier site

Following is the code I am using to create the supplier site

PROCEDURE XX_CREATE_VENDOR_SITE AS

l_vendor_site_rec ap_vendor_pub_pkg.r_vendor_site_rec_type;

l_return_status     VARCHAR2(10);

l_msg_count     NUMBER;

l_msg_data  VARCHAR2(1000);
