Customer intercompany invoice - A/P-A/R accounting

Good Morning!

I would like to create inter-company invoices from A/P-A/R accounting module with the functions Customer intercompany invoice and Supplier intercompany invoice.

I managed to create 2 journals, but the purchase journal that must be generated does not correspond to indicated in the function: Intercompany account mapping

By other hand, this generated 2 journal but not the purchase invoice.

Have you ever used this function?

Thank you very much for your help.

Greetings.
