Dear everyone,

i would like to suggest, that the requested ship and receipt date in the purchase order line is calculated correctly, while using the standard direct delivery function. The business scenario requires, that the feature "Supplier requested and confirmed shipment dates" is activated and the procurement and sourcing parameter "Calculate purchase order delivery date based on lead time and working days" are collaborating correctly. Both in combination unfortunately lead to a miscalculation of the requested ship and receipt date, whenever a purchase order with an active purchase agreement is created out of the direct delivery function.

Short version of the current issue (a more detailed one can be found below):

Requested ship date and requested receipt date is calculated differently in head and line details of a purchase order, which is created by a direct delivery process. The requested receipt date will be postponed by the supplier into the feature, which shouldn't be possible. It only appears, if there is an effective purchase agreement for the supplier, purchase transport days is defined between supplier and customer and procurement and sourcing parameter "Calculate purchase order delivery date based on lead time and working days" is activated. 

Detailed Version with an case study:

We are looking at a direct delivery process between a supplier, which is located in Italy, and a customer/receiver, who is located in Germany. For international delivery we have set up purchase transport days to define the time of transport of goods between supplier and customer (e.g., 7 Days from Italy to Germany). Additionally, we have an effective purchase agreement for the supplier with a lead time of 0.

Now we starting the direct delivery process by creating a sales order, choosing the correct product (which is included in the purchase agreement), and using the direct delivery function in the action pane. In the sales order we are setting the requested ship date and the requested receipt date to 15.04.2024. We are using the supplier in Italy and activate the "Search for purchase agreements" button and as a result a purchase order is being created. With the new feature we would expect, that the requested ship date will be calculated backwards by 7 days to ensure a requested receipt date of 15.04.2024. While the header in the purchase order has calculated the requested ship date correctly to 08.04.2024, the date information in the line details are incorrect. Here, the requested ship date is set to the initial 15.04.24 and the receipt date has been calculated to 22.04.24. In our opinion the requested receipt date shouldn't be able to be changed by the supplier and there is inconsistent data between header and line details. 

After troubleshooting the incident and debugging with our developer we have figured out, that the calculation of requested ship/receipt date in the line details is influenced by a parameter of procurement and sourcing. When the parameter "Calculate purchase order delivery date based on lead time and working days" is activated, the issue described above is occurring. Being deactivated and repeating the same procedure again, the requested and receipt date are calculated correctly in the head and in the line details. 

Consequently this means, that the customer will receive their products with a big delay, only because the requested ship date is set to the feature instead of to the past. To avoid this issue, the new feature and the parameter should corrabolate smoothly, so the requested receipt date is not postponed by the supplier.
