Maintain the Back-to-Back (BtB) purchase order

Select the Work with sales order menu item.
On the Work with sales orders, Header view panel, select the sales order and click Lines.
On the Order lines panel, select the BtB sales order line and click BtB.

You access Work with purchase orders, Order lines, which is the maintenance panel for the purchase order that is connected to the sales order. See Change a purchase order for instructions about how to maintain the order. Note: The connected purchase order can also be found via the BtB list printout the Sales order enquiry or the BtB purchase overview enquiry. Note: Depending on the changes you make and the status of both the purchase order and sales order, they may have an impact on the sales order. (See Impact of changing the Back-to-Back (BtB) sales order and/or purchase order for an outline of this impact).

Delivery times
Knowing when the goods will be delivered to your transit stock or directly to your customer is imperative. The system calculates the delivery and arrival times as follows:

Transit deliveries:

Date/Time

Result

Purchase order dispatch date

(meaning supplier dispatch time)

Dispatch date on sales order – transport time – 1 security day

It is either security day or week, depending on the Delivery date format in Work with companies.

Goods arrival time
into your transit stock

Purchase order dispatch date + transport time

Direct deliveries:

Purchase order dispatch date (meaning supplier dispatch time)	Dispatch date on sales order
Goods arrival time at your customer	Since you do not know the transport time from the supplier to the customer, the goods arrival time is the same as the Purchase order dispatch date.

When you finish the maintenance, you continue with the work order flow applicable for the type of delivery. See Work flow for Back-to-Back (BtB) orders with direct delivery or Work flow for Back-to-Back (BtB) orders with transit delivery for a description.
