We have a Make to order with Project scenario (similar to strategy 21). We are using Requirement Class 80 and Requirement type KP.
When we create a Sales order, through user exit, WBS element is created automatically. Billing element is WBS element.
There is no network/network activity in our scenario.
When we run MRP, a planned order with type "KD" is created. Here the Account assignment category is "D"(individual customer order/project). Special stock indicator is "E" (sales order stock) and the consumption is "P" (project).
Here the sales order number is copied to planned order, whereas the WBS element is not copied into planned order (you can see this in "Assignment" tab in planned order). Because of this we are not able to convert Planned order into Production Order. As the account assignment category is "D", WBS Element is mandatory.
Problem is occurring recently and it was working well earlier.
Please provide me solution for this problem
