The PO header has two separate fields: [Direct delivery] and [Intercompany direct delivery]
But SO header has only one. The field is labeled as "Direct delivery" but the actual field name is "Intercompany direct delivery".
When you create a direct delivery PO from a sales order, field [Direct delivery] on PO header is properly populated.
But if SO has [Direct delivery] field also marked, then [Intercompany direct delivery] field on the PO header is also marked.
Expected situation:
There should have been two fields on the Sales order header and customer: [Direct delivery], [Intercompany direct delivery].
Application should allow marking the intercompany one only when the customer and the sales order are really intercompany.
The field [Intercompany direct delivery] on the PO header should be populated only if the corresponding SO header has [Intercompany direct delivery] is marked.
