In MRP Run screen,There is a line called "Create purchase req"
there are 3 options
1 Purchase Requisitions
2 Purchase requisitions in <b>opening period</b>
3 Planned Orders
What is that opening period?
When i should go for 2nd option?
What is the necessary of creating a planned order rather than a purchase requisition?
If you choose 1 , that means it will create always PR for total planning
If you choose 2 , it will create PR for Opening period which you have mentioned in scedule margin key and more then openning period it will planned order , MRP controller will have hold or when it reqs he will convert to PR
If it is 3 , It will be awlays Planned order and MRP controller will decide to convert PR or not
