Mass creation of Supplier list

Hi,

I have just read a lot of discussions about the problems that I am about to explain, but nothing resolved.

We need to do a program of Supplier List mass creation. The criteria to group them is Product Category and Purchase Organization. The Idea is Upload an excel with Prod Category ID supplier and Pur. Organization on the Function BBP_PD_AVL_CREATE,  and generate a new guid with Function GUID_CREATE.

Which fields have to be completed to run the Function succesfully?

When we run the function BBP_PD_AVL_CREATE, with some fields, the error-messages are:

Interface data contains errors

Incorrect interface data for set &1 in method &2

We are in SRM 702.

Regards,
