Hello,
Requirement Type is KE for planning strategy 20
Requirement type KMFA is for Assembly processing w. production orders that is strategy 82.
So when sales order is created system will create the production order.
So in OVZG for requirement class 201 you can set the Order type as PP03
If it not the assembly to order then the order type is used which is set via the production scheduling profile OPKP.
Please refer,
Planning Strategies - Assembly-to-order (LO-ASM) - SAP Library
