Although this forum is in English, but the user have clearly stated his inability to communicate in English so I’m going to translate it.
The user is objecting to the behavior of Production Orders being automatically delayed and it’s effects distorting the Profit and Loss statement.
The user states that when he tries to enter a production order dated 2 Jul it gets automatically changed to 2 Aug which causes the month of July to show Zero cost and a 100% margin.
