MRP Summary Inquiry
The information in MRP Summary Inquiry (23.13) is similar to that shown in Master Schedule Summary Inquiry, but the MRP summary includes information about planned orders, which are MRP calculated. In general:
• The Master Schedule Summary Inquiry deals in more detail with demand, forecasts, and sales orders, and displays one row of supply: the Master Schedule.
• The MRP Summary Inquiry deals more with the supply orders, showing only one line of demand, the Gross Requirements. Then gives detail of when planned orders are due, must be released, and are scheduled for receipt.
Planned Orders Due are calculated to satisfy demand from sales orders, forecasts, and so on.
Planned Orders Release indicates when the planned orders should be released to meet the due date. MRP calculates by backward scheduling from the due date, using the lead time and shop calendar information.
Once a planned order is released, it becomes a scheduled receipt and no longer appears on the Plan Ord Rel line but rather on the Sched Receipt line.
