We have added fields Simple Shipment Invoice Investment Account and Simple Shipment Invoice Investment Cost Center.
Field Simple Shipment Invoice Investment Account is displayed as default for invoices identified as simple shipment in program Nationalization/Incoming Documents Generation (IM3100).The account selected must meet the following requirements:

• Type: It must be equal to Asset, Liability, Expense or Revenue.
• The account must be of system and not generate entries in stock and of requisitions.

To generate the parent invoice and child invoice, follow these steps:

• Perform the import process as usual up to the program Shipments Follow-up Maintenance (IM0055).
• In program Nationalization/Incoming Docs Gen (IM3100), select parameter Parent Invoice, in folder Simple Shipment. Use a nature of operation exempt from taxes, to not calculate the taxes.

In parent invoice, the trade notes of the goods and expenses registered in program Shipments Follow-up Maintenance (IM0055) are generated for the nationalization point. 
The import tax values and statistics rate are calculated, but no trade notes are generated of these expenses. The value of these expenses is only taken into account for stock updates, to correctly deduct the value when the child invoice is updated.
Field Import Declaration is disabled when option Parent Invoice is selected.

• In program Incoming Documents Maintenance (RE3001), you must update the invoice generated.

In the parent invoice the orders and purchase orders are not generated to not change the data of the Purchases module when this invoice is updated. The receipt of stock is diverted to the investment account entered in import parameters: each item of this invoice does not update the stock so that, in the inflow of child invoices, the value considered for adjusting the investment account is the value of the incoming invoice.

• In program Preparation for Partial Shipment (IM0099), you must break up this shipment in smaller shipments.
• In program Nationalization/Incoming Docs Gen (IM3100), select parameter Child Invoice, in folder Simple Shipment, and nationalize the smaller shipments. Use a nature of operation with regular taxation. When you select option child invoice, the suspense account receives the value of the investment account of simple shipment.

• In program Incoming Documents Maintenance (RE3001), you must update the invoice generated.

In the child invoices, the purchase orders involved are considered as usual for the stock update.
