Hi Sarah,
First - do you really reserve components “ASAP” to your created shop orders? Or perhaps you wait with creating your shop orders until close their scheduled start date? Well, you almost know me after all DDMRP training :-) I usually send back a couple of questions.
What you can look into is our functionality for Shop Order Auto processing. In Manufacturing Standards Basic Data you have the Shop Order Process Types.
You can define that you would like to:
Create Shop Orders - x number of days prior start date
Release Shop Orders - x number of days prior start date
Reserve Shop Orders - x number of days prior start date (and of course - the components must be in stock in order to reserve the shop order component lines)
Then you can define and setup a schedule for when you want to run “Auto Processing of Shop Order”
If you look into this and play with this in a test database I’m sure you will understand.

In general when it comes to DDMRP and planning and execution it is good to work in the pages:
- Demand Driven Planning for Parts (tip - use conditional formatting to color the zones in a nice way)
- Demand Driven Execution for Parts (tip - use conditional formatting to color the zones in a nice way)
I mean in DDMRP you prioritize by buffer status. You want to protect the buffers. It is different from the normal mrp world where everything is by due date.
