Eric,
OK. Where are the CO09's I asked for?
To confirm, here are the detailed steps you took:
you did not change any production orders
you did change the MM strategy to 40
the original production order still exists
you added a new sales order against this material, using the same customer data.
the new sales order uses the same storage location and same plant as the old sales doc.
The sales doc confirmed to a different date.
Best Regards,
