is only one company.
We need create a one purchOrder with somes lines from sales orders.
When i try
"Procurement and sourcing - Common - Purchase orders - All purchase orders - (button option) - from sales order.
I select some lines (lines from all my sales order from different projects) and then click accept buttton
The system repond:
"When sales orders with different project numbers are selected, you cannot create purchase orders."
so.
this restriction is inside of a class
"Class PurchCreateFromSalesOrder Method Chekline"
but why?
what´s is the problem ?
