Create Intercompany AP Invoices - Document category Code is null

 Hi, 

When I run the "Create Intercompany AP Invoices" program it creates records in the AP interface tables but the document category code is null so I can´t import them into AP with out manually assigning a document category code first.  

My guess is that it´s because the document category is missing a sequence as we haven´t used intercompany invoicing before. However I can´t find what document category the program is supposed to use. 

Do you know if the "Create Intercompany AP Invoices" program is supposed to populate the "Document category Code" field and if so with what value?
