Mass Produce Purchase Orders

Hello,

I have a client that wants to mass produce, 1000+, purchase orders in a week.

So far these options are non starters:

• EDI - Supplier won't implement EDI so supplier schedules are not an option.
• Blanket agreements and releases
  • Too time consuming due to volume
• Copying POs
  • Too time consuming

Possible Options

• Forecasting independent demand
  • MRP creating purchase requisitions
    • Using Purchase Order Processing Types and Auto Processing
      • Automatically Release POs
• Data Migration jobs to and events to create large numbers of POs

Has anyone dealt with large volume PO creation without using supplier schedules?

Thanks in advance
