Context: a manufacturing plant pushes inventory to a nearby warehouse where all shipments to other regions and final customers.

On hand inventory (and inventory in transit from the manufacturing plant) are the only receipts seen by ATP at the warehouse. Therefore, the production schedule, that is generally used to confirm sales orders, is not accounted for by ATP.

You want the production schedule to be seen by ATP, but said production schedule shows on the manufacturing plant only.


The Mirror makes the production schedule visible by ATP at the warehouse by creating a stock transfer requisition between the plant and the warehouse, corresponding to each receipt at the plant.

    6. Then hit:

    7. You may also add collaborators to your ticket.
    8. Note that you may ask for more than one flow in one ticket.
  2. Have the Planned Delivery time of all products involved updated at the receiving plant.
    1. the PDT should cover the time that spans from the GI at the shipping plant until the expected GR at the receiving plant.
    2. Note: if Purchasing Info Records exist for that combination (receiving plant / shipping plant / material), make sure the PDT in the PIR is either set to blank, or at least coherent with the above
    3. in case of complex processes where QC Analysis is involved, you want to refer to this documentation
  3. Have the 'push' flag updated at the shipping plant (manufacturing plant)
  4. You're all set. 
    1. you probably want to give it a try.  Use transaction ZDP_1C_PUSH to test it. This transaction lets you run the mirror on-demand.
